MEMORANDUM ORDER In 2024, a hacker accessed the data of 294,000 Allegheny Health Network patients. The hacker then posted the data for ransom on the so-called “dark web,” where the personal and confidential information of these AHN patients is still for sale. Plaintiffs—current and former AHN patients—have brought this putative class action against AHN and AHN’s IT vendor, IntraSystems, LLC, because of the data breach. AHN and IntraSystems move to dismiss. ECF 54; ECF 56. Both argue that Plaintiffs lack Article III standing and that Plaintiffs fail to otherwise state viable state-law claims. After careful review, the Court finds that Plaintiffs have standing. But not all of Plaintiffs’ claims are legally appropriate, so the Court grants in part and denies in part the motions to dismiss. For the reasons below, Plaintiffs’ claims for negligence (Count I), breach of fiduciary duty (Count II), breach of implied contract (Count III), unjust enrichment against AHN (Count V), and declaratory judgment (Count VI) survive with some modification. The Court dismisses Plaintiffs’ claims for breach of contracts to which Plaintiffs were third-party beneficiaries (Count IV), and unjust enrichment against IntraSystems (Count V). BACKGROUND AHN is a health network local to Pittsburgh that has 14 hospitals, over 200 primary and specialty care practices, over 300 clinical locations, and employs about 2,600 physicians. ECF 44 at ¶ 4. Patients must provide their health network with personal information for effective treatment, so AHN collects and stores information like patients’ names, dates of birth, addresses, SSNs, financial account numbers, and health insurance identification numbers. Id. at ¶ 1. Plaintiffs refer to this type of information as personally identifiable information (“PII”) and protected health information (“PHI”), and the Court does the same. AHN uses IntraSystems to secure and protect its patients’ PII and PHI. Id. at ¶ 6. On January 17, 2025, AHN announced in a press release that “IntraSystems experienced a cybersecurity incident that led to the unauthorized access to computer systems” which stored AHN’s patients’ PII and PHI. Id. at ¶ 58. According to that press release, the hack started on October 11, 2024, and AHN learned of the event on November 19, 2024. Id. at ¶ 61. The hack affected the PII and PHI of 294,000 AHN patients, including all named Plaintiffs. Id. at ¶¶ 9, 64. The hacker then took the stolen information and advertised it on the dark web. Id. at ¶ 11. A hacker called “LockBit3.0” ransomed Plaintiffs’ PII and PHI on February 27, 2025, where Plaintiffs’ information is still available as of the filing of this action. Id. at ¶¶ 79–80. All five named Plaintiffs share similar allegations. Each allege that their data was intentionally accessed, downloaded, and published for ransom to the dark web by a known hacker. ECF 62 at 5; see ECF 44 at ¶ 80 (“Anyone who can access the dark web can download Plaintiffs’ and Class Members’ PII and PHI. . . .”). And each allege that since learning of the hack, they have suffered from “stress, anxiety, worry, and fear.” ECF 44 at ¶¶ 98 (Brooks), 108 (Foti), 116 (Kehr), 124 (Silliman-Guyer), 132 (Weltz). With these facts, Plaintiffs are suing AHN and IntraSystems. Against both Defendants, Plaintiffs have claims for negligence (Count I), breach of contracts to which Plaintiffs were the third-party beneficiaries (Count IV), unjust enrichment (Count V), and declaratory judgment (Count VI). Against only AHN, Plaintiffs have claims for breach of fiduciary duty (Count II) and breach of implied contract (Count III). Both Defendants move to dismiss. ECF 54; ECF 56. The Court received full briefing on the motion (ECF 55; ECF 57; ECF 62; ECF 63; ECF 66; ECF 67), so both motions are ready for disposition. STANDARD OF REVIEW “To survive a 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.” Ashcroft v. Iqbal, 556 U.S. 662, 678 (2009) (cleaned up). “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.” Id. Any reasonable inferences should be considered in the light most favorable to the plaintiff. See Lula v. Network Appliance, 255 F. App’x 610, 611 (3d Cir. 2007) (citing Rocks v. City of Phila., 868 F.2d 644, 645 (3d Cir. 1989)). DISCUSSION & ANALYSIS I. Plaintiffs have Article III standing. To establish standing under Article III, a plaintiff must have “(1) suffered an injury in fact, (2) that is fairly traceable to the challenged conduct of the defendant, and (3) that is likely to be redressed by a favorable judicial decision.” Spokeo, Inc. v. Robins, 578 U.S. 330, 338 (2016). “The plaintiff, as the party invoking federal jurisdiction, bears the burden of establishing these elements.” Id. In a class action, each named plaintiff must have standing. See Lewis v. Gov’t Emps. Ins. Co., 98 F.4th 452, 459 (3d Cir. 2024). AHN and IntraSystems contend that this Court thus must separate out each of the five named Plaintiffs and analyze standing one by one. ECF 55 at 3; ECF 57 at 1. Sort of. When each plaintiff alleges roughly the same facts, a plaintiff-by-plaintiff analysis isn’t needed. See Tignor v. Dollar Energy Fund, Inc., 745 F. Supp. 3d 189, 200 (W.D. Pa. 2024) (Stickman, J.) (evaluating each plaintiff’s standing separately only where the factual allegations “diverge”). Because the five named Plaintiffs here all share roughly the same allegations, the Court does just one standing analysis.1 At the outset, the Court notes that it has already written on the standing issues that arise in data-breach cases in Zimmerman v. Highmark, Inc., 780 F. Supp. 3d 588 (W.D. Pa. 2025) (Ranjan, J.). The Court finds that the framework laid out in Zimmerman—based on the Third Circuit’s decision in Clemens v. ExecuPharm Inc., 48 F.4th 146 (3d Cir. 2022)—represents the appropriate legal framework for this case, too. So the Court writes with reference to Zimmerman as it proceeds through the standing analysis here. A. Plaintiffs have pled an injury in fact. An injury in fact must be: (1) either actual or imminent; and (2) concrete.2 Spokeo, 578 U.S. at 339. Here, Plaintiffs base their standing argument on “the threat

1 Were this Court to proceed plaintiff-by-plaintiff, the outcome would remain the same: Plaintiffs have standing. But the Court’s reasoning would differ slightly. For example, the Court below assesses whether Plaintiffs have alleged a sufficiently imminent injury. But as AHN and IntraSystems acknowledge, under a plaintiff-by- plaintiff approach, Ms. Foti and Ms. Brooks have suffered an actual injury. See ECF 55 at 6 n.2; ECF 57 at 14–15. So a plaintiff-by-plaintiff analysis would only strengthen certain Plaintiffs’ standing arguments. In this way, the shared facts that the Court considers act as the least common denominator for standing.
