DAWN O’HARA PAGAN, individually and on behalf of all others similarly situated,

Plaintiff, Case No. 2:25-cv-14907 (BRM) (JSA)

v. OPINION

AVANTIC MEDICAL LAB, INC.,

Defendant.

MARTINOTTI, DISTRICT JUDGE Before the Court is Plaintiff Dawn O’Hara Pagan’s (“Plaintiff”) Motion for Class Certification pursuant to Federal Rule of Civil Procedure (“Rule”) 23 and for Default Judgment as to the issue of liability only pursuant to Rule 55(b) (the “Motion”). (ECF No. 14.) Defendant Avantic Medical Lab, Inc. (“Avantic”) has not appeared in this matter. The Court has jurisdiction under 28 U.S.C. § 1332.1 Having reviewed the submission filed in connection with the Motion and having declined to hold a hearing pursuant to Federal Rule of Civil Procedure 78(b), for the reasons set forth below and for good cause having been shown, Plaintiff’s Motion for Class Certification (ECF No. 14) is GRANTED and Plaintiff’s Motion for Default Judgment (ECF No. 14) is GRANTED IN PART and DENIED IN PART.

1 The Court specifically has jurisdiction over this action under the Class Action Fairness Act, because the amount in controversy exceeds five million dollars, the number of proposed class members is greater than one hundred, and at least one member of the proposed class is a citizen of a state diverse from Avantic. 28 U.S.C. § 1332(d)(2). I. BACKGROUND For the purpose of a class certification motion, the Court must conduct a “rigorous analysis” of the facts, evidence, and arguments submitted. See In re Lamictal Direct Purchaser Antitrust Litig., 957 F.3d 184, 187 (3d Cir. 2020). Upon a motion for default class certification, the Court accepts all of Plaintiff’s well pleaded facts as true, which “extends to specific allegations

relating to the prerequisites for class certification” and then performs the Rule 23 analysis. Lehman v. Calls After Hours, LLC, Civ. A. No. 18-2601, 2019 WL 8405591, at *2 (N.D. Ohio Aug. 16, 2019). The Court may also consider any “document integral to or explicitly relied upon in the complaint.” In re Burlington Coat Factory Sec. Litig., 114 F.3d 1410, 1426 (3d Cir. 1997) (quoting Shaw v. Digit. Equip. Corp., 82 F.3d 1194, 1220 (1st Cir. 1996)). A. Factual Background This action arises out of a cyberattack and data breach, which allegedly targeted Avantic’s IT Network on July 3, 2025 (the “Data Breach”). (ECF No. 1 ¶ 1.) The Data Breach resulted in unauthorized access to the Private Information (“PI”), including the Private Health Information (“PHI”) and Personally Identifiable Information (“PII”)2, of approximately 1,400 individuals

(proposed “Class Members”), including named plaintiff Dawn O’Hara Pagan. (ECF No. 14-1 at 1.) Plaintiff seeks to recover damages on behalf of the Class Members for Avantic’s failure to secure its IT Network. (ECF No. 1 ¶¶ 16–19.)

2 Because the Health Insurance Portability and Accountability Act (“HIPAA”) protects PHI and the Federal Trade Commission (“FTC”) Act empowers the FTC to enforce various forms of PII, the Court will refer to the total private information disclosed in the Data Breach as “PI.” Citizens for Health v. Leavitt, 428 F.3d 167, 173 (3d Cir. 2005) (explaining HIPAA prohibits “‘covered entities’. . . from using or disclosing an individual's ‘protected health information’); F.T.C. v. Wyndham Worldwide Corp., 799 F.3d 236, 248 (3d Cir. 2015) (explaining the various acts of Congress which protect consumers’ personal information, information collected from children, and consumer data, within the FTC’s ambit). Avantic is a full-service clinical laboratory, which provides a wide array of diagnostic testing services. (Id. ¶ 25.) As a clinical laboratory, the proposed Class Members entrusted Avantic with their necessary and highly sensitive PI. (Id. ¶ 26.) Plaintiff alleges Avantic “promise[d] and represent[ed]” to these individuals the PI collected from them would be kept safe and confidential, and the privacy of the information would be maintained. (Id. ¶ 27.) Avantic, however, neither

encrypted the PI nor deleted information when it was no longer needed. (Id. ¶ 35.) Non-party Everest Ransomware Group (“Everest”) is a notorious cybercriminal group, which has been active since December 2020. (Id. ¶ 33.) Everest targets organizations across different industries and regions, which has included a number of high-profile victims such as NASA and the Brazilian Government. (Id. ¶ 33.) On June 10, 2025, Everest added a listing to its leak site, accompanied by a one-week countdown clock and four screenshots containing patient information as proof of its claims of obtaining PI stored in Avantic’s IT Network. (Id. ¶ 30.) On July 3, 2025, Everest leaked thirty-one gigabytes of proposed Class Members’ files, including PI such as names, addresses, telephone numbers, Social Security numbers, medical record numbers,

referring doctors, and their personal health insurance, medical, and financial information. (Id. ¶ 31.) B. Procedural History Plaintiff filed her Class Action Complaint against Avantic on August 26, 2025. (ECF No. 1.) Plaintiff seeks to recover damages on behalf of the 1,400 individuals whose files were leaked in the Data Breach. (Id. ¶¶ 16–19.) Plaintiff asserts four counts in her Complaint: (1) Negligence; (2) Negligence Per Se; (3) Breach of Implied Contract; and (4) Unjust Enrichment. (See id.) Plaintiff served Avantic on September 3, 2025. (ECF No. 5.) Avantic’s deadline to file a responsive pleading was September 24, 2025. (Id.) To date, Avantic has neither filed a responsive pleading nor appeared in this action. (ECF No. 14-1 at 2.) On December 3, 2025, Plaintiff filed a request for entry of default pursuant to Rule 55(a) (ECF No. 10), which the Clerk entered against Avantic (Clerk’s Entry dated December 4, 2025). On December 29, 2025, Plaintiff filed this Motion for Class Certification and Default Judgment on the issue of liability pursuant to Rules 23 and 55(b).3 (ECF No. 14-1.) To date,

Avantic has not opposed the Motion or appeared in this action. II. DEFAULT CLASS CERTIFICATION A. Legal Standard A class action under Rule 23 is “an exception to the usual rule that litigation is conducted by and on behalf of the individual named parties only.” Wal-Mart Stores v. Dukes, 564 U.S. 338, 348 (2011) (citing Califano v. Yamasaki, 442 U.S. 682, 700–01 (1979)). “To invoke this exception, every putative class action must satisfy the requirements of Rule 23(a) and the requirements of either Rule 23(b)(1), (2), or (3).” Marcus v. BMW of N. Am., LLC, 687 F.3d 583, 590 (3d Cir. 2012). A party seeking class certification must first demonstrate the proposed class satisfies the

four requirements of Rule 23(a): (1) the class is so numerous that joinder of all members is impracticable;

(2) there are questions of law or fact common to the class;

(3) the claims or defenses of the representative parties are typical of the claims or defenses of the class; and
