***-***tems.*** Listed by devman Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On December 14, 2025, the organization ***-***tems.*** appeared on a leak site operated by the ransomware group devman. The listing states that internal files were exfiltrated during a ransomware operation. No figure for the number of people affected has been reported, and the precise contents of the material have not been disclosed publicly. Ransomware groups continue to combine encryption of systems with the removal of data for later leverage. Listings on dedicated leak sites form part of that pattern, allowing the actors to pressure organizations that do not meet ransom demands.

Inside the incident

The only confirmed information is the appearance of ***-***tems.*** on the devman leak site on the reported date. The group claims to have stolen internal data. No details on the timing of the intrusion, the volume of data taken, the method of initial access, or any ransom demand have been made public. It remains unconfirmed whether the organization has acknowledged the incident or whether any data has been published beyond the listing itself.

Who is devman?

Devman is a ransomware group that maintains a leak site to list organizations from which it claims to have obtained data. Such groups typically encrypt victim systems and remove copies of files, then use the threat of disclosure to encourage payment. Public records of the group’s prior activity show repeated use of this dual tactic of encryption and data exposure, though specific claims regarding any single victim must be treated as unverified until corroborated by the affected organization or independent investigation.

About ***-***tems.***

***-***tems.*** operates in a sector that routinely manages internal operational records, client or project documentation, and administrative systems. Organizations of this type hold data necessary for day-to-day functions, including communications and technical materials. Exposure of such holdings can affect both the organization’s own continuity and any third parties referenced in the files.

The information in question

The listing refers to “internal files exfiltrated in ransomware attack.” No further breakdown of file types, categories, or sensitivity levels has been released. Organizations in this sector commonly store records such as contracts, employee information, technical specifications, and correspondence. The exact scope and nature of the material allegedly taken from ***-***tems.*** remain unconfirmed.

Why it matters

Internal files can contain details that, if disclosed, allow inference about business relationships, ongoing projects, or personnel. For the organization, the incident adds operational disruption from any encryption that occurred alongside the exfiltration. For individuals or partners referenced in the data, the primary concern is the potential for the material to be used in further targeted activity, though the likelihood and form of any such use cannot be assessed from the information currently available.

If your data was in this claimed breach

Monitor official statements from ***-***tems.*** for any confirmation or guidance. Review accounts that may be referenced in internal records for unusual activity. Enable or strengthen multi-factor authentication on systems that could be linked to the organization. A short list of immediate actions includes:

• Change passwords for any accounts associated with ***-***tems.***
• Check bank and credit statements for unrecognized entries
• Run a free exposure scan of your email address against known breach data
• Retain records of any correspondence from the organization about the incident
