    BLOM BANK SAL,

    Defendant-Appellee. †
    ______________
    Before:
    POOLER, WESLEY, CARNEY, Circuit Judges.
    Plaintiffs-Appellants sued BLOM Bank SAL (“BLOM Bank”) for aiding and
    abetting Hamas, designated as a foreign terrorist organization by the United
    States, in carrying out attacks in which Plaintiffs-Appellants and their relatives
    were injured or killed. They allege BLOM Bank aided and abetted Hamas’s attacks
    in violation of the Anti-Terrorism Act (“ATA”), 
    18 U.S.C. § 2333
    , as amended by
    the Justice Against Sponsors of Terrorism Act (“JASTA”), by providing financial
    services to customers affiliated with Hamas. The district court granted BLOM
    Bank’s motion to dismiss for failure to state a claim under Federal Rule of Civil
    Procedure 12(b)(6) (“Rule 12(b)(6)”), concluding that Plaintiffs-Appellants did not
    plausibly allege BLOM Bank aided and abetted Hamas’s attacks. Plaintiffs-
    Appellants argue that the district court misapplied the standard for JASTA aiding-
    and-abetting liability, and that their complaint suffices to survive a Rule 12(b)(6)
    dismissal. Although we agree that the court did not apply the proper standard,
    Plaintiffs-Appellants’ complaint nonetheless fails to state a claim. Accordingly,
    we AFFIRM the judgment of the district court.

    WESLEY, Circuit Judge:
    Plaintiffs-Appellants and their family members (collectively, “Plaintiffs”) 1
    were injured or killed in attacks carried out by Hamas, which the United States
    has designated as a foreign terrorist organization. They sued BLOM Bank SAL
    (“BLOM Bank”) for aiding and abetting Hamas’s attacks by providing financial
    services to customers affiliated with Hamas, in violation of the Anti-Terrorism Act
    (“ATA”), 
    18 U.S.C. § 2333
    , as amended by the Justice Against Sponsors of
    Terrorism Act (“JASTA”), 
    id.
     § 2333(d)(2). The United States District Court for the
    Eastern District of New York (Matsumoto, J.) granted BLOM Bank’s motion to
    dismiss for failure to state a claim under Federal Rule of Civil Procedure 12(b)(6),
    concluding that Plaintiffs failed to plausibly allege BLOM Bank aided and abetted
    Hamas’s attacks in violation of JASTA. Plaintiffs argue on appeal that the district
    court erred in dismissing their complaint because it applied the wrong standard
    for JASTA aiding-and-abetting liability. Although we agree that the court did not
    apply the proper standard, we affirm its judgment because Plaintiffs’ complaint
    fails to state a claim under the correct standard.
    1
    As alleged, Plaintiffs brought this action on behalf of themselves and as representatives
    of the estates of their family members who died in the attacks.
    4
    BACKGROUND
    The United States government has designated Hamas 2 as a foreign terrorist
    organization (“FTO”) since 1997. 3 Between December 1, 2001 and August 19, 2003,
    Hamas carried out a series of attacks, including shootings and bombings, in Israel
    and the Palestinian territories in which Plaintiffs were injured or killed. BLOM
    Bank is a Lebanese bank that operates internationally. Plaintiffs sued BLOM Bank
    for damages under the ATA for allegedly aiding and abetting Hamas’s attacks by
    providing financial services to three customers affiliated with Hamas: the Sanabil
    Association for Relief and Development (“Sanabil”), Subul al-Khair, and the Union
    of Good (collectively, the “Three Customers”).
    I. Plaintiffs’ Complaint
    As alleged, Hamas operates a “civilian infrastructure” called the “da’wa,”
    which translates in Arabic to “the call to the believers to shelter beneath the faith”
    2“‘Hamas’ is an acronym for the Arabic phrase ‘Harakat al-Muqawama al-Islamiya,’
    sometimes translated as the ‘Islamic Resistance Movement.’ . . . In accordance with
    common usage, we refer to it here as ‘Hamas.’” Linde v. Arab Bank, PLC, 
    706 F.3d 92
    , 97
    n.6 (2d Cir. 2013) (internal citation omitted).
    3
    The U.S. Secretary of State “is authorized to designate an organization as a foreign
    terrorist organization” if it “engages in terrorist activity” or “retains the capability and
    intent to engage in terrorist activity” and “the terrorist activity . . . threatens the security
    of United States nationals or the national security of the United States.” 
    8 U.S.C. § 1189
    (a)(1).
    5
    and provides “social welfare activities.” J.A. 141, 141 n.6. One of the founders of
    Hamas explained in an interview in 1998 that “[s]ocial work is carried out in
    support of [Hamas’s aim to liberate Palestine from Israeli occupation], and it is
    considered to be part of the [Hamas] movement’s strategy.” 
    Id. at 141
    . In the early
    1990s, Hamas pursued a “three-pronged strategy” to strengthen its influence:
    (1) improving its military capacity, (2) “intensify[ing] its efforts to systematically
    gain control” of institutions important to the Palestinian public, and (3)
    “accelerat[ing] the development of its world-wide fundraising network.” 
    Id. at 143
    .
    A. The Three Customers: Sanabil, Subul al-Khair, and Union of
    Good
    Hamas established Sanabil in 1994 “with the unofficial goal of competing
    with H[i]zbollah’s [(a designated terrorist organization’s)] social welfare
    infrastructure.” 
    Id. at 152
    . Sanabil was Hamas’s “da’wa headquarters in Lebanon
    until late 2003.”   
    Id. at 154
    .   It distributed funds it received from Hamas’s
    fundraising network to Palestinian refugee camps in Lebanon “to build [Hamas’s]
    support within that community.” 
    Id. at 154
    . Its board members were well-known
    leaders of Hamas in Lebanon. In August 2003, a Lebanese newspaper reported
    that pursuant to an order by a Hamas political leader, Sanabil had opened offices
    6
    in all of the Palestinian refugee camps in Lebanon. “Sanabil regularly distributed
    small sums in cash from its accounts to hundreds (if not thousands) of individual
    dependents in the Palestinian refugee camps under the categories of ‘Orphan
    Sponsorships,’ ‘Student Sponsorships,’ ‘Needy Sponsorships’ and ‘Family
    Sponsorships.’” 
    Id. at 159
    . As a Lebanese publication reported in 2004, Sanabil
    “sponsored 1,200 Palestinian families and spent around $800,000 on orphans and
    $55,000 on needy patients.” 
    Id.
    On August 22, 2003, the U.S. Department of the Treasury designated Sanabil
    as a Specially Designated Global Terrorist (“SDGT”), 4 finding that it is “part of a
    web of charities raising funds on behalf of [Hamas] and using humanitarian[]
    purposes as a cover for acts that support [Hamas].” 
    Id. at 147
    . The Treasury
    Department explained in a press release:
    [Hamas] recruits permanent members from the religious and the
    poor by extending charity to them from organizations such as
    Sanabil. . . . After starting by providing basic necessities the charity
    eventually began asking poor families within the camps to fill out
    application forms, particularly those who had worked with the
    Islamic Movement . . . and [Hamas].
    4
    The “SDGT designation is distinct from the State Department’s FTO designation.” Weiss
    v. Nat’l Westminster Bank PLC, 
    768 F.3d 202
    , 209 n.7 (2d Cir. 2014). The Treasury
    Department is authorized to designate groups and individuals who “pose a significant
    risk of committing[] acts of terrorism” or “are determined . . . to assist in, sponsor, or
    provide financial, material, or technological support for . . . acts of terrorism” as SDGTs
    under Executive Order 13224. See Exec. Order No. 13224, 
    3 C.F.R. § 13224
     (2001).
    7
    
    Id. at 155
    . Sanabil was also “identified . . . as an unindicted co-conspirator” in the
    U.S. government’s 2004 prosecution of the Holy Land Foundation (“HLF”), a
    charity designated as an SDGT, which transferred money to Sanabil. 
    Id. at 159
    .
    Subul al-Khair was founded in 1998 in Beirut, Lebanon, and “functioned
    much like Sanabil, but was more focused on [Hamas] supporters in the Beirut
    area.” 
    Id. at 161
    . It “regularly distributed small sums in cash from its accounts to
    individual[s] under the categories of ‘Orphan Sponsorships’ and ‘Student
    Sponsorships.’” 
    Id.
     Subul al-Khair was not designated as an SDGT; however, it
    was listed as an unindicted co-conspirator in HLF’s criminal trial.
    Union of Good was founded in 2000 “as the umbrella organization for
    [Hamas’s] global fundraising activity.” 
    Id. at 162
    . It “originally began as a limited
    101-day fundraising drive for emergency aid at the outset of what was later called
    the Second Intifada.” 5 
    Id.
     Because of its success, Union of Good became a
    permanent institution and “raise[d] tens of millions of dollars for [Hamas].” 
    Id.
    5
    The “Second Intifada” was “a period [in the early 2000s] of intensified violence by
    Palestinian terrorist groups in the aftermath of failed peace negotiations between Israel
    and the Palestinian Authority.” See Linde v. Arab Bank, PLC, 
    882 F.3d 314
    , 319 (2d Cir.
    2018).
    8
    The U.S. Department of the Treasury designated Union of Good as an SDGT in
    November 2008. 6 
    Id. at 163
    . The Treasury Department’s press release noted:
    Union of Good acts as a broker for [Hamas] by facilitating financial
    transfers between a web of charitable organizations––including
    several organizations previously designated . . . for providing
    support to [Hamas]––and [Hamas]-controlled organizations in the
    West Bank and Gaza. The primary purpose of this activity is to
    strengthen [Hamas’s] political and military position in the West
    Bank and Gaza, including by: (i) diverting charitable donations to
    support [Hamas] members and the families of terrorist operatives;
    and (ii) dispensing social welfare and other charitable services on
    behalf of [Hamas]. . . . In addition to providing cover for [Hamas]
    financial transfers, some of the funds transferred by the Union of
    Good have compensated [Hamas] terrorists by providing
    payments to the families of suicide bombers.”
    
    Id. at 163
    . The chairman of Union of Good, Sheikh Yusuf al-Qaradawi, gave
    interviews in 2002 and later years commending Hamas’s suicide attacks and
    martyrdom operations.
    B. BLOM Bank’s Financial Services to the Three Customers
    Each of the Three Customers held accounts at BLOM Bank. Sanabil held its
    account at BLOM Bank “[d]uring the relevant period (1999-2003).” 
    Id. at 156
    .
    6
    Israel also “designated” Union of Good in 2002 “in an order of the Minister of Defense
    of the State of Israel, based on its being ‘part of the Hamas organization or supporting it
    and strengthening its infrastructure.’” J.A. 162. The complaint does not specify what
    designation Israel gave Union of Good.
    9
    Three organizations in Hamas’s fundraising network transferred money to
    Sanabil’s account at BLOM Bank. Specifically:
    (1) HLF, a charity based in the U.S., “transferred over $2 million . . .
    through BLOM [Bank’s] correspondent bank accounts in New York
    to Sanabil’s bank account(s) at BLOM [Bank] in Lebanon.” 
    Id.
     The
    last payment from HLF to Sanabil was on September 7, 2001. The
    U.S. Department of the Treasury designated HLF as an SDGT on
    December 4, 2001; the complaint does not allege BLOM Bank
    processed any payments from HLF to Sanabil after HLF’s
    designation.
    (2) KindHearts, a charity based in the U.S. which “succeeded to
    HLF’s fundraising for [Hamas] after HLF was designated,” “sent
    an additional $250,000 to Sanabil’s accounts between July 2002 and
    July 2003.” 
    Id. at 158
    . BLOM Bank processed these transfers to
    Sanabil’s account. The complaint does not allege KindHearts was
    designated as an SDGT.
    (3) The Al-Aqsa Foundation (“Al-Aqsa”), a charity based in
    Germany, “transferred at least $50,000 into Sanabil’s accounts at . . .
    BLOM [Bank] between April – May 2003.” 
    Id.
     at 158–59 (emphasis
    omitted). Al-Aqsa was designated as an SDGT on May 29, 2003;
    BLOM Bank processed one transfer from Al-Aqsa to Sanabil the
    day after Al-Aqsa’s designation. The complaint does not allege
    BLOM Bank processed any later transfers from Al-Aqsa to Sanabil.
    In an invoice attached as an exhibit to the complaint, the stated purpose of
    the payment from Al-Aqsa to Sanabil’s account at BLOM Bank was “help
    concerning orphan children.” 
    Id.
     at 177–78.
    Subul al-Khair also maintained an account at BLOM Bank and BLOM Bank
    “deposited multiple transfers sent by HLF to Subul al-Khair.” 
    Id. at 161
    . “HLF
    10
    sent Subul al-Khair over $500,000 between 1999 and 2001,” but the complaint does
    not specify whether BLOM Bank processed that entire amount or some portion of
    it. 
    Id.
     The complaint does not provide dates or further information regarding the
    financial services BLOM Bank provided for Subul al-Khair.
    Union of Good held an account with BLOM Bank. The complaint does not
    identify any dates for this account; nor does it note the transactions, if any, BLOM
    Bank processed for Union of Good.
    II. Applicable Law
    The ATA authorizes U.S. nationals “injured in his or her person, property,
    or business by reason of an act of international terrorism” to sue for treble damages
    as well as attorney’s fees and costs. 7        
    18 U.S.C. § 2333
    (a).   “[I]nternational
    terrorism” encompasses “activities that—(A) involve violent acts or acts
    dangerous to human life that . . . would be a criminal violation if committed within
    the jurisdiction of the United States or of any State,” “(B) appear to be intended—
    to (i) to intimidate or coerce a civilian population; (ii) to influence the policy of a
    government by intimidation or coercion; or (iii) to affect the conduct of a
    government by mass destruction, assassination, or kidnapping,” and “(C) occur
    7
    Before the enactment of JASTA in 2016, the ATA did not specify which parties could be
    sued. See 
    18 U.S.C. § 2333
    (a).
    11
    primarily outside the territorial jurisdiction of the United States.” 
    Id.
     § 2331(1)(A)–
    (C).
    The ATA did not expressly permit relief against parties who aided the
    primary perpetrator of the act of international terrorism. JASTA, Pub. L. No. 114-
    222, 
    130 Stat. 852
     (2016), amended the ATA to create a cause of action against “any
    person who aids and abets, by knowingly providing substantial assistance, or who
    conspires with the person who committed . . . an act of international terrorism.” 8
    
    18 U.S.C. § 2333
    (d)(2). JASTA applies to “any civil action . . . pending on, or
    commenced on or after, the date of [its] enactment . . . and . . . arising out of an
    injury to a person, property, or business on or after September 11, 2001.” 130 Stat.
    at 855. Congress was clear that its purpose in enacting JASTA was to:
    [P]rovide civil litigants with the broadest possible basis, consistent
    with the Constitution of the United States, to seek relief against
    persons, entities and foreign countries, wherever acting and
    wherever they may be found, that have provided material support,
    directly or indirectly, to foreign organizations or persons that engage
    in terrorist activities against the United States.
    Id. at 853 (emphases added). Congress also specifically endorsed the reasoning of
    the D.C. Circuit in Halberstam v. Welch, 
    705 F.2d 472
     (D.C. Cir. 1983) in conducting
    8
    The term “person” includes corporations. See 
    18 U.S.C. § 2333
    (d)(1) (incorporating the
    definition of “person” in 
    1 U.S.C. § 1
    ).
    12
    the aiding-and-abetting analysis. 
    Id. at 852
    . “Halberstam . . . provides the proper
    legal framework for how [aiding and abetting] liability [under the ATA] should
    function.” 
    Id.
     (emphasis added).
    Under Halberstam, there are three elements for aiding-and-abetting liability:
    “(1) the party whom the defendant aids must perform a wrongful act that causes
    an injury” (the “aiding party who causes injury” element); “(2) the defendant must
    be generally aware of his role as part of an overall illegal or tortious activity at the
    time that he provides the assistance” (the “general awareness” element); “(3) the
    defendant must knowingly and substantially assist the principal violation” (the
    “substantial assistance” element). 
    705 F.2d at 477
     (emphases added).
    III. The District Court’s Decision
    The district court granted BLOM Bank’s motion to dismiss for failure to state
    a claim pursuant to Federal Rule of Civil Procedure 12(b)(6) (“Rule 12(b)(6)”),
    concluding that Plaintiffs’ complaint did not plausibly allege that BLOM Bank
    aided and abetted Hamas’s attacks. See Honickman for Est. of Goldstein v. BLOM
    Bank SAL, 
    432 F. Supp. 3d 253
    , 271 (E.D.N.Y. 2020). In the court’s view, Plaintiffs
    failed to allege the latter two elements of JASTA aiding-and-abetting liability:
    “(1) that [BLOM Bank] was generally aware of its role as part of an overall illegal
    or tortious activity at the time that it provided the assistance, and (2) that [BLOM
    13
    Bank] knowingly and substantially assisted the principal violation.” 
    Id. at 263
    (alterations in original, internal quotation marks, and citation omitted).
    As to general awareness, the court first found “Plaintiffs’ complaint does
    not plausibly allege that BLOM [Bank] was generally aware of any connection
    between the Three Customers and Hamas.” 
    Id. at 265
    . It then concluded that
    “even if Plaintiffs’ allegations plausibly alleged that BLOM [Bank] knew the Three
    Customers were related to Hamas, ‘[e]vidence that [BLOM Bank] knowingly
    provided banking services to [Hamas], without more, is insufficient to satisfy
    JASTA’s scienter requirement.’ . . . Plaintiffs have not plausibly alleged that BLOM
    [Bank] knew that by providing financial services to the Three Customers, it was
    playing a role in Hamas’s violent activities.” 
    Id.
     at 265–66 (second alteration in
    original) (citation omitted). Regarding substantial assistance, the court analyzed
    the six factors identified in Halberstam, discussed below, and ruled that “[t]he
    complaint fails to establish that BLOM[] [Bank’s] provision of financial services to
    the Three Customers amounted to providing ‘substantial assistance’ to Hamas.”
    
    Id. at 268
    .
    Plaintiffs argue on appeal that: (1) the district court applied the wrong legal
    standard in evaluating the sufficiency of their complaint; and (2) their complaint
    14
    plausibly alleges that BLOM Bank was generally aware of its role in Hamas’s
    illegal activities and that BLOM Bank knowingly provided substantial assistance
    to Hamas.
    DISCUSSION
    “We review de novo a district court’s dismissal of a complaint under Rule
    12(b)(6), accepting all of the complaint’s [non-conclusory] factual allegations as
    true and drawing all reasonable inferences in the plaintiffs’ favor.” Giunta v.
    Dingman, 
    893 F.3d 73
    , 78–79 (2d Cir. 2018). It is well established that:
    [t]o survive a [Rule 12(b)(6)] motion to dismiss, a complaint must
    contain sufficient factual matter, accepted as true, to state a claim
    to relief that is plausible on its face. A claim has facial plausibility
    when the plaintiff pleads factual content that allows the court to
    draw the reasonable inference that the defendant is liable for the
    misconduct alleged. The plausibility standard is not akin to a
    probability requirement, but it asks for more than a sheer
    possibility that a defendant has acted unlawfully. Where a
    complaint pleads facts that are merely consistent with a
    defendant’s liability, it stops short of the line between possibility
    and plausibility of entitlement to relief.

    15
    I. The Standard for JASTA Aiding-and-Abetting Liability
    The “Aiding Party Who Causes Injury” Element
    The first element, that “the party whom the defendant aids must perform a
    wrongful act that causes an injury,” Halberstam, 
    705 F.2d at 477
    , is straightforward.
    It is satisfied when the party whom the defendant directly or indirectly aided
    performed the injury-causing act. BLOM Bank argues that Plaintiffs’ complaint
    falls short because “the only parties whom BLOM [Bank] allegedly ‘aided’ are the
    [Three] Customers,” and “JASTA limits aiding-and-abetting liability to those
    circumstances in which a defendant actually ‘aided and abetted . . . the person who
    committed’ the relevant ‘act of international terrorism.’” Appellee’s Br. at 63
    (emphasis omitted) (quoting 
    18 U.S.C. § 2333
    (d)(2)). We recently rejected the same
    contention in Kaplan v. Lebanese Canadian Bank, SAL, 
    999 F.3d 842
     (2d Cir. 2021),
    holding that “[t]he language and purpose of JASTA are meant to allow an aiding-
    and-abetting claim where the defendant’s acts aided and abetted the principal”
    who committed the wrongful act “even where [the defendant’s] relevant
    substantial assistance was given to an intermediary” of the principal. 
    Id. at 856
    .
    B. The “General Awareness” Element
    The second (“general awareness”) and third (“substantial assistance”)
    elements form the crux of most JASTA aiding-and-abetting cases. The “general
    16
    awareness” element requires the defendant to be “generally aware” of its role in
    “an overall illegal or tortious activity at the time that [it] provides the assistance.” See
    Halberstam, 
    705 F.2d at 477
     (emphasis added). The defendant need not be generally
    aware of its role in the specific act that caused the plaintiff’s injury; instead, it must
    be generally aware of its role in an overall illegal activity from which the act that
    caused the plaintiff’s injury was foreseeable. See 
    id. at 477, 488
    .
    Halberstam establishes this foreseeability principle. There, the D.C. Circuit
    held that Linda Hamilton was civilly liable for aiding and abetting the murder of
    Michael Halberstam during a burglary of his home by Bernard Welch, Hamilton’s
    partner, even though she was unaware of Welch’s plan to burglarize or kill
    Halberstam. See 
    id. at 474, 488
    . Over the five years Hamilton and Welch lived
    together, Welch acquired significant wealth by selling stolen goods that he
    obtained through burglaries. 
    Id. at 475
    . Although Hamilton was never present
    during Welch’s burglaries and claimed she was unaware that they were occurring,
    she performed the “secretarial work” for Welch’s illegal enterprise, such as typing
    transmittal letters for sales of the stolen goods and keeping inventories of the
    stolen goods that were sold. 
    Id.
    17
    The court concluded that the “sudden influx of great wealth” Hamilton and
    Welch experienced, “the filtering of all transactions through Hamilton except
    payouts for [the] goods” sold, and “Hamilton’s collusive and unsubstantiated
    treatment of income and deductions on her tax forms . . . combine[d] to make the
    district court’s inference that [Hamilton] knew [Welch] was engaged in illegal
    activities acceptable, to say the least.” 
    Id. at 486
    . Indeed, given the facts, “it
    [would] def[y] credulity that Hamilton did not know that something illegal was
    afoot.” 
    Id.
    Hamilton’s “general awareness of her role in [Welch’s] continuing criminal
    enterprise,” 
    id. at 488
    , sufficed to establish her liability for aiding and abetting
    Halberstam’s murder because the murder was a foreseeable consequence of Welch’s
    illegal activity. As the court explained:
    [U]nder an aiding-abetting theory, [the murder] was a natural and
    foreseeable consequence of the activity Hamilton helped Welch to
    undertake. It was not necessary that Hamilton knew specifically that
    Welch was committing burglaries. Rather, when she assisted him, it
    was enough that she knew he was involved in some type of personal
    property crime at night—whether as a fence, burglar, or armed
    robber made no difference—because violence and killing is a
    foreseeable risk in any of these enterprises.
    18
    
    Id.
     (emphases added). 9 Foreseeability is thus central to the Halberstam framework,
    and as a result, to JASTA aiding-and-abetting liability. 10
    The district court, however, rejected the foreseeability principle, holding
    that “it is not enough for Plaintiffs to plausibl[y] allege that BLOM [Bank] was
    generally aware of [its] role in terrorist activities, from which terrorist attacks were
    a natural and foreseeable consequence.” Honickman, 432 F. Supp. 3d at 264 (first
    and third alterations in original) (emphasis, internal quotation marks, and citation
    omitted). The court’s conclusion contravenes both Halberstam and Linde v. Arab
    9
    The Halberstam court extracted the foreseeability principle from American Family Mutual
    Insurance Co. v. Grim, 
    201 Kan. 340
     (1968), in which a group of teenagers broke into a
    church at night looking for soft drinks in the kitchen. See Halberstam, 
    705 F.2d at 482
    . Two
    of them failed to extinguish the torches they used to light their way to the attic, causing
    the church to catch on fire. See 
    id.
     The defendant, one of the teenagers, did not know
    about the torches, did not enter the attic, and was not near the church when it caught on
    fire. See 
    id.
     Still, he was found liable for damages caused by the fire because as part of
    the attempt to reach the church attic, “the need for adequate lighting could reasonably be
    anticipated,” making the use of torches and subsequent fire foreseeable. See 
    id. at 483
    (citation omitted).
    10
    Halberstam did not specifically attach foreseeability to the general awareness or
    substantial assistance elements; it used foreseeability broadly for establishing the extent
    of liability under an aiding-and-abetting theory. See 
    705 F.2d at
    482–83. As a result, it is
    more important that courts do not skip foreseeability altogether rather than apply it at a
    precise stage of the JASTA aiding-and-abetting analysis.
    19
    Bank, PLC, 
    882 F.3d 314
     (2d Cir. 2018), one of the first cases in which we interpreted
    aiding-and-abetting liability under JASTA. 11
    Linde was brought before JASTA was enacted. The plaintiffs alleged that a
    defendant bank was liable as a principal under the ATA for committing an act of
    terrorism by “knowingly providing” material support to an FTO in the form of
    “financial services.” Linde, 882 F.3d at 318. At trial, the district court instructed
    the jury that the “provision of material support to [an FTO in violation of a distinct
    statute, 18 U.S.C. § 2339B] . . . necessarily proved the bank’s commission of an act
    of international terrorism” under the ATA. Id. at 325. We held that this instruction
    was erroneous because providing material support to an FTO does not qualify
    under the definition of “an act of international terrorism.” Id. at 326. However,
    the plaintiffs argued on appeal that the availability of aiding-and-abetting liability
    under JASTA, enacted between the time of trial and the appeal, 12 made the error
    in the jury instruction harmless.      Id. at 328.   Linde rejected their argument,
    determining that:
    11
    We acknowledge that the district court’s decision came before our opinion in Kaplan
    clarified the import of our earlier JASTA aiding-and-abetting precedents which may have
    generated some ambiguity as to the proper standard.
    12
    We agreed that the plaintiffs were entitled to invoke JASTA on appeal because the act
    applies retroactively. See Linde, 882 F.3d at 328.
    20
    aiding and abetting an act of international terrorism requires more
    than the provision of material support to a designated terrorist
    organization. Aiding and abetting requires the secondary actor to
    be ‘aware’ that, by assisting the principal, it is itself assuming a
    ‘role’ in terrorist activities. Halberstam[], 
    705 F.2d at 477
    . Such
    awareness may not require proof of the specific intent demanded
    for criminal aiding and abetting culpability . . . . Nor does
    awareness require proof that Arab Bank [(the defendant)] knew of
    the specific attacks at issue when it provided financial services for
    Hamas. What the jury did have to find was that, in providing such
    services, the bank was ‘generally aware’ that it was thereby playing
    a ‘role’ in Hamas’s violent or life-endangering activities.
    Halberstam[], 
    705 F.2d at 477
    . This is different from the mens rea
    required to establish material support in violation of 18 U.S.C. § 2339B,
    which requires only knowledge of the organization’s connection to
    terrorism, not intent to further its terrorist activities or awareness that
    one is playing a role in those activities. See Holder v. Humanitarian Law
    Project, 
    561 U.S. 1
    , 16–17 . . . (2010).
    Linde, 882 F.3d at 329–30 (some emphases omitted and others added) (footnotes
    and internal citation omitted).
    Here, the district court misread this passage from Linde to conclude that
    applying the Halberstam foreseeability standard to the “general awareness”
    element would contravene Linde by “replac[ing] the scienter for aiding-and-
    abetting liability with the lower scienter required for [criminal] material support.”
    Honickman, 432 F. Supp. 3d at 264. The court erred in equating the foreseeability
    standard and the scienter required for criminal material support; the two are
    21
    distinct. In doing so, the court also implicitly perceived Linde as requiring more
    than the Halberstam standard for general awareness, which we rejected in Kaplan.
    “[N]othing in Linde repudiates the Halberstam standard that a defendant
    may be liable for aiding and abetting an act of terrorism if it was generally aware
    of its role in an ‘overall illegal activity’ from which an ‘act of international
    terrorism’ was a foreseeable risk.” Kaplan, 999 F.3d at 860. Nor could it, of course,
    given Congress’s unambiguous assignment of Halberstam as the appropriate legal
    framework for JASTA aiding-and-abetting liability. Linde’s holding that aiding-
    and-abetting “requires more than the provision of material support to a terrorist
    organization,” 882 F.3d at 329, means only that allegations that a defendant
    “knowingly provid[ed] material support to an FTO, without more, does not as a
    matter of law satisfy the general awareness element.” Kaplan, 999 F.3d at 860
    (emphasis added). That language “does not establish that [a defendant’s provision
    of] material support to an FTO is never sufficient for [JASTA] aiding-and-abetting
    liability.”   Id. (emphasis added).   Instead, “[w]hether a defendant’s material
    support to an FTO suffices to establish general awareness is a fact-intensive
    inquiry” depending on allegations that a defendant “was generally aware . . . that
    22
    it was playing a role in unlawful activities from which [terrorist] attacks were
    foreseeable.” Id. at 860–61 (emphasis added).
    On the other hand, we reject Plaintiffs’ attempt to equate the Halberstam
    foreseeability standard with the “fungibility” theory in Holder v. Humanitarian Law
    Project, 
    561 U.S. 1
     (2010). Linde recognized that general awareness “is different
    from the mens rea required to establish material support in violation of 18 U.S.C.
    § 2339B, which requires only knowledge of the organization’s connection to
    terrorism . . . . See Holder[,] 561 U.S. [at] 16–17.” Linde, 882 F.3d at 329–30. In Holder,
    a criminal material support case under § 2339B, the plaintiffs 13 knowingly
    provided material support to FTOs but claimed they were “seek[ing] to facilitate
    only the lawful, nonviolent purposes of those groups.” 
    561 U.S. at
    7–8. The
    Supreme Court determined that for the purpose of § 2339B, it did not matter that
    the “[m]aterial support [was] meant to promote peaceable, lawful conduct”
    because “[m]oney is fungible” and “there is reason to believe that foreign terrorist
    organizations do not maintain legitimate financial firewalls between those funds
    13
    The plaintiffs were U.S. organizations and citizens who challenged the constitutionality
    of the criminal material support statute (18 U.S.C. § 2339B) and sought an injunction to
    prohibit its enforcement. See Holder, 
    561 U.S. at
    10–11.
    23
    raised for civil, nonviolent activities, and those ultimately used to support violent,
    terrorist operations.” 
    Id.
     at 30–31 (internal quotation marks and citations omitted).
    Plaintiffs urge us to adopt Holder’s “fungibility” rationale in assessing the
    sufficiency of their complaint. They contend that Linde merely recognized that the
    mens rea for aiding and abetting is “different” from criminal material support, not
    that it is “higher.” Appellants’ Br. at 44. However, Linde determined that the facts
    in Holder––adequate for criminal material support––fall short for the general
    awareness element of JASTA aiding and abetting. 882 F.3d at 329–30. Indeed,
    Linde could not have been clearer: aiding and abetting “requires more than the
    provision of material support to a designated terrorist organization,” 882 F.3d at
    329.   Plaintiffs’ fungibility argument would displace the aiding-and-abetting
    standard with the standard for criminal material support by making “knowingly
    providing material support to an FTO, without more” sufficient “as a matter of
    law” for the general awareness element. See Kaplan, 999 F.3d at 860. Not only
    would this erase Linde’s distinction between general awareness and criminal
    material support, but it would also evade Halberstam’s foreseeability standard. 14
    14
    Plaintiffs rely on Boim v. Holy Land Found. for Relief & Dev., 
    549 F.3d 685
     (7th Cir. 2008),
    a pre-JASTA case in which the Seventh Circuit held that the causation element of primary
    liability under the ATA, 
    18 U.S.C. § 2333
    (a), is satisfied when the defendant knowingly
    24
    Accordingly, the relevant inquiry for the general awareness element is: did
    Plaintiffs “plausibly allege[] the [Three] Customers were so closely intertwined
    with [Hamas’s] violent terrorist activities that one can reasonably infer that [BLOM
    Bank] was generally aware while it was providing banking services to those
    entities that it was playing a role in unlawful activities from which [Hamas’s]
    attacks were foreseeable[?]” 15 Kaplan, 999 F.3d at 860–61.
    C. The “Substantial Assistance” Element
    The last element for aiding-and-abetting liability requires that the defendant
    “knowingly and substantially assist[ed] the principal violation.” Halberstam, 
    705 F.2d at 477
    . As the analysis in Halberstam reveals, the “principal violation” must
    be foreseeable from the illegal activity that the defendant assisted; knowing and
    substantial assistance to the actual injury-causing act––here, Hamas’s attacks––is
    unnecessary. See 
    id. at 488
    .
    donated money to a terrorist organization because “[a]nyone who knowingly contributes
    to the nonviolent wing of an organization that he knows to engage in terrorism is
    knowingly contributing to the organization's terrorist activities.” 
    549 F.3d at 698
    . Boim
    is inapposite. It was decided before Congress assigned Halberstam as the appropriate
    framework for JASTA aiding-and-abetting liability claims and therefore lacks the
    requisite analysis. Moreover, any persuasive value it might have is insufficient to
    overcome the binding effects of Linde and Kaplan on us.
    15
    Contrary to BLOM Bank’s argument, the Three Customers do not themselves need to
    be “engaged in . . . violent or terrorist acts.” See Appellee’s Br. at 32–34.
    25
    The district court appeared to impose a higher standard on the “knowing”
    prong of “knowingly and substantially” assisted than required, concluding that
    “Plaintiffs’ complaint fails plausibly to allege that any assistance BLOM [Bank]
    provided––even if substantial––would have been knowing.” Honickman, 432 F.
    Supp. 3d at 268. The “knowledge component” is satisfied “[i]f the defendant
    knowingly––and not innocently or inadvertently––gave assistance.” 16 Kaplan, 999
    F.3d at 864. For instance, Halberstam held that “the district court . . . justifiably
    inferred that Hamilton assisted Welch with knowledge that he had engaged in
    illegal acquisition of goods.” 
    705 F.2d at 488
    . It did not require Hamilton to
    “know” anything more about Welch’s unlawful activities than what she knew for
    the general awareness element.
    How much aid qualifies as substantial assistance? Halberstam identified six
    factors:
    (1) the nature of the act encouraged, (2) the amount of assistance
    given by defendant, (3) defendant’s presence or absence at the time
    16 BLOM Bank argues in its post-argument letter brief that under Kaplan, “where a
    complaint alleges that the assistance was indirect, it must allege (among other things) that
    the defendant had ‘actual knowledge’ of the intermediary’s connection to the FTO.”
    Appellees’ Letter Br. at 14. Kaplan did not so hold; instead, it asserted “the actual
    knowledge component of the Halberstam standard requires that the defendant ‘know[ ]’
    that it is providing ‘assistance,’ . . . whether directly to the FTO or indirectly through an
    intermediary.” 999 F.3d at 863–64 (alteration in original) (citation omitted).
    26
    of the tort, (4) defendant’s relation to the principal, (5) defendant’s
    state of mind, and (6) the period of defendant’s assistance.
    Linde, 882 F.3d at 329 (citing Halberstam, 
    705 F.2d at
    484–85). No factor is
    dispositive; the weight accorded to each is determined on a case-by-case basis. See
    Halberstam, 
    705 F.2d at 483
    ; see also Kaplan, 999 F.3d at 856.
    The district court misunderstood the first factor, “the nature of the act
    encouraged,” to be a question of whether Plaintiffs plausibly alleged “that BLOM
    [Bank] knowingly encouraged Hamas’[s] violent activities, such as those which
    caused Plaintiffs’ injuries.” Honickman, 432 F. Supp. 3d at 268. However, the
    “nature of the act involved dictates what aid might matter.” 17 See Halberstam, 
    705 F.2d at 484
     (emphasis omitted). As a result, the factor requires assessing whether
    the alleged aid (facilitating the transfer of millions of dollars to the Three
    Customers) would be important to the nature of the injury-causing act (Hamas’s
    terrorist attacks).
    For the second factor, the “amount of assistance,” the district court held
    “Plaintiffs make no non-conclusory assertions that any of the funds processed by
    the Three Customers actually went to Hamas, or that BLOM [Bank], at the time it
    17
    For example, verbal encouragement of “physical acts of violence” may be important to
    a principal’s commission of battery. See Halberstam, 
    705 F.2d at 484
    .
    27
    provided banking services to the Three Customers, was aware or intended that
    Hamas would receive the corresponding funds.” Honickman, 432 F. Supp. 3d at
    268. However, Plaintiffs did not need to allege the funds “actually went to
    Hamas.” Factual allegations that permit a reasonable inference that the defendant
    recognized the money it transferred to its customers would be received by the FTO
    would suffice. See Kaplan, 999 F.3d at 866. In other words, if a plaintiff plausibly
    alleges the general awareness element, she does not need to also allege the FTO
    actually received the funds. Instead, the inquiry should focus on the amount and
    type of aid the defendant provided. See Halberstam, 
    705 F.2d at 488
    .
    Lastly, the fourth factor, the “defendant’s relation to the principal,” is useful
    for determining the defendant’s capacity to assist. See 
    id. at 484
    . The district court
    erroneously construed this Court’s finding in Siegel v. HSBC N. Am. Holdings, Inc.,
    
    933 F.3d 217
     (2d Cir. 2019), that “the plaintiffs d[id] not plead any non-conclusory
    allegations that [the defendant-bank] had any relationship with [the FTO]” to
    mean that Plaintiffs must plead a direct relationship between BLOM Bank and
    Hamas. 
    Id. at 225
    ; see Honickman, 432 F. Supp. 3d at 269. In Siegel, the defendant-
    bank’s “relation to the principal” was several steps removed: it allegedly had a
    commercial relationship with another bank that was linked to various terrorist
    28
    organizations including the FTO that caused the plaintiffs’ injuries. See 933 F.3d at
    220–21. Although the relationship between the defendant and the FTO should not
    be so attenuated as in Siegel, a direct relationship between the defendant and the
    FTO is not required to satisfy this factor.
    II. The Sufficiency of Plaintiffs’ Complaint
    For Plaintiffs’ JASTA aiding-and-abetting claim to be viable, the complaint
    must plausibly allege all three elements of the Halberstam standard for aiding-and-
    abetting liability.
    The first element, that the party whom the defendant aided performed the
    injury-causing act, merits little attention. Plaintiffs plausibly allege that the party
    whom BLOM Bank aided (indirectly), Hamas, committed attacks causing
    Plaintiffs’ injuries. For the second element, general awareness, the complaint must
    plausibly allege: (1) as a threshold requirement, that BLOM Bank was aware of the
    Three Customers’ connections with Hamas before the relevant attacks; and (2) the
    Three Customers were so closely intertwined with Hamas’s violent terrorist
    activities that one can reasonably infer BLOM Bank was generally aware of its role
    in unlawful activities from which the attacks were foreseeable while it was
    providing financial services to the Three Customers. See Kaplan, 999 F.3d at 860.
    29
    For the final element of substantial assistance, the complaint must contain
    sufficient factual allegations relating to the six factors identified above.
    We conclude that Plaintiffs’ aiding-and-abetting claim fails because the
    allegations do not support an inference that BLOM Bank was aware of the Three
    Customers’ ties with Hamas prior to the relevant attacks, thereby undermining the
    second element of general awareness. In assessing this element, the district court
    found that the complaint’s references to media articles and publications on the
    Three Customers’ connection to Hamas were insufficient because “Plaintiffs
    fail[ed] plausibly to allege that BLOM [Bank] . . . actually knew or should have
    known of any of the cited sources.” Honickman, 432 F. Supp. 3d at 265. However,
    as we explained in Kaplan, Plaintiffs did not need to allege that BLOM Bank knew
    or should have known of the public sources at the pleading stage. See 999 F.3d at
    865. Such a requirement at this juncture would be too exacting.
    Nevertheless, the public sources cited in the complaint do not plausibly
    support an inference that BLOM Bank had the requisite general awareness at the
    time that it provided banking services to the Three Customers. See Halberstam, 
    705 F.2d at 477
     (“[T]he defendant must be generally aware of [its] role . . . at the time
    that [it] provides the assistance.”) (emphasis added). One of the news articles on
    30
    Sanabil referenced in the complaint was dated August 27, 2004, more than a year
    after the last relevant attack, and reported only that Sanabil sponsored Palestinian
    families and spent money on orphans. The Lebanese press’s coverage of Sanabil’s
    center in Sidon closing due to “its links to [Hamas]” is undated. J.A. 159. The
    complaint lacks any allegations that at the time of the interviews in which al-
    Qaradawi––who chaired Union of Good––praised martyrdom and criticized the
    United States’ designation of Hamas, it was public knowledge that al-Qaradawi
    chaired Union of Good. 18       Indeed, the Treasury Department’s press release,
    announcing the designation of Sanabil and similar organizations as SDGTs only
    after the final attack at issue, describes these organizations as using
    “humanitarian[] . . . purposes as a cover for acts that support [Hamas],” which the
    Treasury Department unveiled only after developing “credible evidence” in an
    investigation. J.A. 147 (emphasis added). That organizations like the Three
    Customers maintained a “cover” in public undermines the plausibility of
    18Plaintiffs argue that “the publicly available evidence [in the complaint] was largely
    available before or during the relevant period or discussed facts that were previously
    knowable.” Appellants’ Br. at 39, n.11. However, “publicly available” evidence is not the
    same as public sources such as media articles. The latter, depending on their substance,
    plausibly suggest a defendant’s knowledge which can be confirmed during discovery,
    whereas the former requires the implausible inference that the defendant was aware of
    those facts even before the news media.

    Plaintiffs’ theory that BLOM Bank understood these organizations’ true nature
    and activities from the public record at the time.
    The limited public sources Plaintiffs cite pale in comparison to the detailed,
    numerous sources that sufficed in Kaplan.             See 999 F.3d at 864.        The Kaplan
    complaint alleged Hizbollah made public statements identifying the defendant-
    bank’s customers as “integral parts of Hizbollah” prior to the relevant attacks
    which were “specific as to the status of the speaker,” “the circumstances in which
    the statements were made,” and “the other specific media in which they were
    made,” including Hizbollah’s own websites. Id.
    Plaintiffs’ remaining allegations also fail to suggest BLOM Bank was aware
    of the connections between the Three Customers and Hamas. 19 The complaint
    alleges certain leaders of Hamas were board members of the Three Customers but
    does not aver that this was public knowledge during the relevant period. Sanabil
    and Subul al-Khair were identified as unindicted co-conspirators in HLF’s
    19
    Plaintiffs referenced in their briefs and at oral argument a 2001 FBI report identifying
    Sanabil as a “known front[]” for Hamas. See Appellants’ Br. at 32; Appellants’ Letter Br.
    at 11. Their complaint contained no reference to this FBI report. Similarly, Plaintiffs
    characterized BLOM Bank’s transactions for the Three Customers as “untraceable” for
    the first time in their post-argument letter brief. See, e.g., Appellants’ Letter Br. at 8. “[A]
    Rule 12(b)(6) motion tests the adequacy of the complaint . . . not the briefs.” Hack v.
    President & Fellows of Yale Coll., 
    237 F.3d 81
    , 91 (2d Cir. 2000), abrogated on other grounds by
    Swierkiewicz v. Sorema N.A.,

     (2002), (internal citation omitted).

    criminal trial and/or prosecution, but HLF was not indicted until 2004, after the
    relevant period. Sanabil and Union of Good were not designated as SDGTs until
    after the last relevant attack, and BLOM Bank did not transfer any funds from non-
    customer charities after they were designated as SDGTs except for one transfer
    from Al-Aqsa to Sanabil the day after Al-Aqsa’s designation. We agree with the
    district court that this single post-designation transfer, standing alone, is
    insufficient to suggest BLOM Bank was aware of Sanabil’s links to Hamas. 20
    Because we conclude Plaintiffs failed to plausibly allege BLOM Bank was
    aware the Three Customers were related to Hamas, we do not need to consider
    whether they plausibly alleged the Three Customers were closely intertwined with
    Hamas’s violent terrorist activities. 21 Nor do we need to address whether the
    20
    The allegation that Israel designated Al-Aqsa as a terrorist organization in 1998, without
    specifying whether and where this was made public, is also unavailing. Moreover, even
    if the complaint plausibly alleged it was public knowledge that Al-Aqsa, HLF, and
    KindHearts were linked with Hamas, those entities were not BLOM Bank’s customers.
    Without any further allegations, a defendant-bank’s transfers of funds from non-customers
    associated with an FTO to the defendant’s customers does not compel an inference that
    the defendant knew of its customers’ connections to that FTO.
    21
    However, we note that there is a meaningful difference between the alleged functions
    of the Three Customers and those of the customers in Kaplan. In Kaplan, the plaintiffs’
    theory was that the defendant-bank’s customers provided subsidies to the families of
    Hizbollah suicide bombers––i.e., veterans’ funds for terrorists––and the defendant-bank
    “permitted the laundering of money . . . in violation of regulatory restrictions meant to
    hinder the ability of FTOs to carry out terrorist attacks.” 999 F.3d at 858, 865. By contrast,
    33
    complaint satisfies the substantial assistance element. The complaint’s failure to
    support a reasonable inference that BLOM Bank knew of the Three Customers’
    links to Hamas sounds the death knell of Plaintiffs’ JASTA aiding-and-abetting
    liability action.
    CONCLUSION
    We AFFIRM the judgment of the district court.
    Plaintiffs’ theory rests on the da’wa, Hamas’s social welfare program, and the Three
    Customers were alleged only to have supported orphans in Palestinian refugee camps.
