Who is avoslocker?
Avoslocker is a ransomware group that emerged in 2021 and follows a double-extortion model. The group typically encrypts systems and also removes copies of data, threatening to publish the material if a ransom is not paid. It maintains a leak site where it lists organizations it claims to have targeted. Public reporting has documented similar activity by the group against other entities in the same period, though each listing represents an unverified claim by the operators.
About Mauck & Baker
Mauck & Baker is a law firm. Organizations of this type routinely hold client records, case files, correspondence, and other materials that contain personal and financial details. A compromise at a legal practice can therefore affect not only the firm’s own employees but also clients whose matters are documented in the affected systems.
What was likely exposed
The only detail provided is that internal files were claimed to have been exfiltrated. The exact categories of data, file counts, or time periods covered have not been disclosed. Law firms commonly store client identifiers, communications, billing information, and sensitive legal documents; however, whether any of these specific items were taken in this case has not been confirmed.
Why it matters
Legal practices maintain records that can include identifying information, financial data, and privileged communications. Exposure of such material can lead to privacy intrusions, identity-related risks, or complications in ongoing legal matters for the individuals and entities involved. For the organization, the incident adds to the operational and reputational consequences that follow any confirmed or claimed ransomware event.

Review any communications from Mauck & Baker for guidance on protective steps. Individuals can also run a free exposure scan of their email address against known breach data sets to check for appearances in previously published incidents.

Publicly posted by avoslocker — 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.
