probat.com Listed by lockbit5 Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
probat.com was listed by the LockBit5 ransomware group on June 11, 2026, after internal files were exfiltrated in a ransomware attack. Anyone who may have had an account or provided data to probat.com should check the company’s site for guidance and take steps to protect their information.
On June 11, 2026, the ransomware group lockbit5 listed probat.com on its leak site, claiming to have exfiltrated internal files from the German company. The number of individuals whose information may be involved remains unknown, and no further details about the scope or confirmation of the incident have been made public. For people connected to the organisation through employment, contracts or services, the listing raises the possibility that documents containing personal or operational information have left the company’s control.
Inside the incident
The only confirmed public information is the listing itself and the statement that internal files were taken during a ransomware attack. No date of intrusion, volume of data, or method of access has been disclosed. The organisation has not issued a statement confirming or denying the claims, and no independent verification of the files’ contents or subsequent use has been reported.
Who is lockbit5?
Lockbit5 belongs to the LockBit ransomware operation, a group that has conducted numerous attacks since at least 2019. The group typically uses ransomware-as-a-service arrangements in which affiliates deploy the malware and the core operators manage infrastructure and a leak site. Its standard approach involves encrypting systems and copying data, then threatening to publish the stolen material if a ransom is not paid. The listing of probat.com follows this pattern; the group claims responsibility, but that claim has not been independently confirmed.
About probat.com
Probat is a medium-sized group of companies headquartered in Emmerich am Rhein, Germany. It operates internationally and maintains internal records typical of a commercial organisation of its size, including employee information, supplier and customer details, and operational documents. A breach at such a company can expose data that individuals and business partners have entrusted to it over time.
What data was at risk
The listing refers only to “internal files exfiltrated in ransomware attack.” No inventory of specific file types or data categories has been released. Organisations of this kind routinely hold personnel records, financial documents, correspondence, and technical information; however, whether any of these categories were actually taken in this case remains unconfirmed.
Why it matters
Internal files can contain identifying details about employees, clients or partners that, if released, may be used for targeted fraud or further social-engineering attempts. For the organisation, the incident adds the cost of investigation, potential regulatory reporting, and the need to review access controls. Because the number of affected individuals is unknown, the practical impact on any single person cannot yet be quantified.
If your data was in this claimed breach
Monitor accounts for unusual activity and consider changing passwords for any services linked to the organisation. Enable multi-factor authentication where available. Individuals can run a free exposure scan of their email address against known breach data to check whether their information appears in previously published sets. Organisations should follow standard incident-response steps, including notifying regulators if required by local law.

Publicly posted by lockbit5 — 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.
