sjl-legal.com Listed by ms13089 Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
sjl-legal.com was listed by the ms13089 ransomware group on 15 January 2026, with internal files reported as exfiltrated. Anyone connected to the firm should verify whether their information was exposed and take steps to protect their data.
On January 15, 2026, the ransomware group ms13089 listed sjl-legal.com on its leak site. The listing states that internal files were exfiltrated during a ransomware attack on the firm. The number of individuals affected remains unknown, and no further details on the volume or contents of the data have been made public.
The incident involves a boutique law firm established in 2010 that specialises in alternative investment funds, finance, corporate matters, and insolvency and restructuring. Public disclosure at this stage is limited to the group’s claim and the general description of the data as internal files.
Inside the incident
The only confirmed information is the listing itself and the statement that internal files were taken. No date of the intrusion, no attack method, and no confirmation of encryption or ransom demands have been released by the firm or by investigators. The scale of the operation and whether data was published or used for further activity also remain undisclosed.
The group behind it: ms13089
ms13089 is a ransomware operator that maintains a public leak site to list victims and, in some cases, to publish stolen material. The group’s listing of sjl-legal.com constitutes a claim by the actor that it obtained internal files; independent verification of that claim has not been reported. Public records show the group has targeted organisations across multiple sectors in prior incidents, typically through ransomware deployment followed by data exfiltration.
About sjl-legal.com
SJL Legal is an independent business law firm founded in 2010. It operates as a boutique practice focused on alternative investment funds, finance, corporate advisory, and insolvency and restructuring work. Firms of this type routinely receive and generate documents that contain details of transactions, client strategies, and regulatory filings.
What data was at risk
The listing refers only to “internal files exfiltrated in ransomware attack.” No inventory of file types, client names, or specific categories has been published. Organisations in this sector commonly hold contracts, financial records, correspondence with clients and regulators, and internal memoranda; whether any of these categories were among the files taken has not been confirmed.
The real-world impact
Exposure of internal legal files can create risks of follow-on fraud, targeted phishing, or reputational harm to clients whose matters appear in the material. For the firm, the incident may affect ongoing client relationships and regulatory obligations concerning data security. Because the number of individuals whose information was involved is unknown, the full scope of personal or commercial consequences cannot yet be assessed.
What to do if you're exposed
Individuals who have been clients of sjl-legal.com or who have corresponded with the firm should monitor their accounts and correspondence for unusual activity. Practical first steps include:
- Reviewing bank and investment statements for unauthorised transactions.
- Changing passwords for any accounts linked to the firm’s matters.
- Enabling multi-factor authentication on email and financial services.
- Contacting the firm directly for any official guidance it may issue.

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.
