Inside coinbasecartel
Coinbasecartel is a ransomware group that maintains a leak site where it lists organizations it claims to have targeted. Such groups typically encrypt systems and remove copies of data, then use the site to pressure victims. The listing of Demand.io constitutes the group’s claim; independent verification of the underlying events has not been provided.

What data was at risk

The real-world impact
Individuals whose information appears in the exfiltrated files face the possibility of future misuse, including targeted phishing or account takeover attempts.

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.
