LOSSEWERK Listed by blackbasta Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The LOSSEWERK Listed by blackbasta Ransomware Group (reported July 6, 2022) 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.
On July 6, 2022, the ransomware group Black Basta listed LOSSEWERK on its data-leak site. The listing stated that internal files had been taken during a ransomware operation. No figure for the number of people affected has been made public, and the organization has not confirmed the claims.
The incident is one of many in which a ransomware operator publicly names a victim and threatens to release stolen material. Because the scale of the data and the method of access remain undisclosed, the practical consequences for individuals or the organization cannot yet be quantified from available information.
What happened
LOSSEWERK appeared on Black Basta’s leak site on July 6, 2022. The group claimed to have exfiltrated internal files during a ransomware attack. No additional details about the timing of the intrusion, the volume of data, or the encryption status of systems have been released. The number of individuals whose information may be involved is also unknown.
Who is blackbasta?
Black Basta is a ransomware group that began publishing victims in early 2022. Like several other contemporary ransomware operations, it follows a double-extortion model: it encrypts systems and also removes data, then uses the threat of publication to pressure victims. The group maintains a leak site where it lists organizations it claims to have targeted. Public reporting has associated the group with attacks on entities in multiple countries and sectors, though specific claims about any single victim remain unverified unless confirmed by the victim or independent investigation.
About LOSSEWERK
LOSSEWERK is the organization named in the July 2022 listing. Public information about its size, sector, or operations is limited in reports of the incident. Organizations that hold internal operational files routinely manage records relating to employees, clients, suppliers, and business processes. When such an entity appears on a ransomware leak site, the primary concern is the potential circulation of those internal records.
What was likely exposed
The only data category named in the listing is internal files exfiltrated during the ransomware attack. The precise contents of those files have not been disclosed. Organizations of this type commonly maintain personnel records, financial documents, contracts, and communications; however, whether any of these categories were taken in this case remains unconfirmed.
Why it matters
Stolen internal files can contain information that is later used for further targeting, fraud, or reputational harm. For the organization, the incident adds the costs of investigation, potential regulatory scrutiny, and remediation. For individuals whose details appear in the files, the main risks are identity misuse or unwanted disclosure of personal or professional information. Without a confirmed inventory of the data, the extent of these risks cannot be assessed from public sources.
If your data was in this claimed breach
Monitor bank, email, and government-service accounts for unusual activity. Enable multi-factor authentication where available and change passwords for any accounts that may have reused credentials. Individuals can also run a free exposure scan of their email address against known breach data sets to check whether their information has appeared in previously published collections.

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.
