trellisware.com Listed by dispossessor Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The trellisware.com Listed by dispossessor Ransomware Group (reported February 4, 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.
What happened
The incident was first reported on 4 February 2022. The only confirmed information is that dispossessor added trellisware.com to its leak-site listing and asserted that internal files had been taken during a ransomware operation. The scale of the intrusion, the method of initial access, and any ransom demand or payment remain undisclosed. No independent confirmation of the data’s authenticity or volume has been published.
Who is dispossessor?
Dispossessor is a ransomware group that publishes victim names on a dedicated leak site when negotiations fail or to increase pressure. Like other groups in this category, it typically combines file encryption with data exfiltration and then threatens to release the stolen material. Public records show the group has listed organisations across multiple sectors in the past, though specific claims about any single victim are treated as unverified until corroborated by the affected organisation or independent investigation.
About trellisware.com
Trellisware.com is the public domain of an organisation that operates in the technology sector, specialising in communications systems. Entities of this type routinely hold internal engineering documents, customer records, partner agreements, and employee data. A breach at such a firm can expose both proprietary technical information and personal details of staff or clients, even when the exact records taken are not disclosed.
What was likely exposed
The listing refers only to “internal files exfiltrated in ransomware attack.” No inventory of file types, record counts, or data categories has been released. Organisations in this sector commonly store technical specifications, contract information, and personnel records, but the precise contents of the exfiltrated material remain unconfirmed.
Why it matters
Even without a published count of affected individuals, the exposure of internal files can create downstream risks including targeted phishing, misuse of technical details, or secondary incidents if credentials or contact information are present. For the organisation, the incident adds operational disruption and potential regulatory scrutiny typical of ransomware events involving data exfiltration.
If your data was in this claimed breach
Monitor official statements from trellisware.com for any notification or guidance. Use a reputable breach-checking service to scan your email address against known public data sets. Enable multi-factor authentication on accounts that may share passwords or email addresses with the organisation, and review recent login activity for any unfamiliar access.

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.
