Centaris.com Listed by alphv Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The Centaris.com Listed by alphv Ransomware Group (reported December 30, 2021) is an unverified claim; the data involved is undisclosed belonging to roughly unknown people. If you have an account with them, your information may now be circulating on the open web and with data brokers. Here’s exactly what happened, how to check if you were affected, and what to do next.
What happened
Public records show only that Centaris.com appeared on the alphv leak site on the reported date. The group claims to have exfiltrated internal files in a ransomware attack. No further details on the timing of the intrusion, the volume of data, or the method of access have been released by either the organization or the group.
Who is alphv?
Alphv, also tracked publicly as BlackCat, is a ransomware-as-a-service operation that first appeared in late 2021. The group typically uses encryption combined with data theft to pressure victims, then posts samples or directories on its leak site when negotiations fail. Its listings function as claims of possession rather than independently verified disclosures.
About Centaris.com
Centaris.com operates as a commercial entity whose internal systems were referenced in the listing. Organizations of this type routinely maintain records related to clients, employees, contracts, and technical operations. Any exposure of such material can affect both the company and parties whose information it holds.
What was likely exposed
The only data category named is internal files exfiltrated during the ransomware attack. The exact types of records, file counts, or whether personal information was included have not been disclosed. Without a published inventory, the contents remain unconfirmed.
Why it matters
Internal files can contain operational details, communications, or third-party information that, if released, may create follow-on risks such as targeted fraud or further intrusions. For the organization, the incident adds costs related to investigation, potential regulatory reporting, and remediation. Individuals cannot yet assess personal exposure because the scale of any data set is unknown.

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.
