What happened
The incident came to light through a listing on the coinbasecartel leak site on 31 January 2026. The group claims to have obtained internal files from CigamSoftware in the course of a ransomware operation. No information has been released on the timing of the intrusion itself, the volume of data involved, or whether any systems were encrypted. Public reporting on the event is limited to the existence of the listing.
The group behind it: coinbasecartel
coinbasecartel is a ransomware operation that has appeared in multiple public listings of compromised organisations. Groups of this type typically gain initial access through phishing, exposed remote services or supply-chain weaknesses, then move laterally to locate and exfiltrate data before deploying encryption. Their listings serve as a form of pressure on victims. The appearance of CigamSoftware on the group’s site constitutes a claim by coinbasecartel; independent confirmation of the data or the attack method has not been provided.
Who is CigamSoftware?
CigamSoftware operates in the software sector. Organisations in this field commonly maintain internal development repositories, customer records, licensing information and administrative systems. A breach at such an entity can expose both the company’s own operational data and any information it holds on clients or partners. The precise nature of CigamSoftware’s business activities and client base is not detailed in available reports on the listing.
What data was at risk
The only data category named in connection with the listing is internal files exfiltrated during the ransomware attack. No inventory of specific file types, databases or record counts has been disclosed. Organisations of this kind routinely store source code, configuration data, employee records and customer-related material, but whether any of these categories were present in the exfiltrated material remains unconfirmed.
- Internal files listed as exfiltrated
- Number of individuals affected: unknown
- Exact data categories: not disclosed
The real-world impact
Exposure of internal files can create operational and reputational consequences for the affected organisation and any third parties referenced in the material. Individuals whose information appears in such files may face risks of targeted phishing or misuse of credentials. Without a confirmed inventory of the data, the scale of personal impact cannot be quantified. The organisation itself may incur costs related to investigation, remediation and any regulatory obligations that arise once the contents are assessed.
If your data was in this claimed breach

Enable or review multi-factor authentication on those accounts and change passwords if reuse is suspected. Check official communications from the company for any guidance it may issue once its investigation concludes.

Publicly posted by coinbasecartel — 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.
