Swartz Campbell Listed by interlock Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Swartz Campbell was listed by the Interlock ransomware group on December 22, 2025, after internal files were taken in a ransomware attack. An undisclosed number of people may have been affected; anyone who has dealt with the firm should review their records and take protective steps.
Inside the incident
Public reporting on the incident is limited to the December 22, 2025 listing. The group claims to have obtained internal files, yet no confirmation of the volume, file categories, or encryption status has been issued by Swartz Campbell or independent investigators. The timing of the initial intrusion, the method of access, and any ransom demand or payment remain undisclosed.
The group behind it: interlock
Interlock is a ransomware operation that has appeared in public reporting since 2024. The group follows a double-extortion model in which data are first copied and later threatened with publication if a ransom is not paid. Its leak sites have listed victims across multiple industries, including legal, healthcare, and manufacturing entities. Claims posted on such sites are unverified until corroborated by the affected organisation or law-enforcement findings.

The information in question
The listing refers only to “internal files exfiltrated in ransomware attack.” No inventory of specific data categories has been published. Law firms commonly retain documents containing names, addresses, Social Security numbers, medical details, employment histories, and litigation materials; however, whether any of these categories appear in the exfiltrated material is unconfirmed.
The real-world impact
Individuals whose records are held by the firm face the possibility that personal or legal documents could be exposed. Such exposure can lead to follow-on fraud, identity misuse, or unwanted disclosure of sensitive proceedings. For the firm itself, the incident creates obligations under attorney-client privilege rules and data-protection regulations, along with potential costs for investigation, notification, and remediation.

Publicly posted by interlock — unverified claim, pending independent verification
Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
