A ransomware group calling itself coinbasecartel claims to have carried out an attack on Kessler Creative, with the claim dated August 22, 2026. This assertion comes from an entry on the group’s own dark-web leak site, which is monitored by ransomware.live, a security research platform that tracks the public claims made by ransomware operators. At this time, the claim is unverified — it has not been confirmed by Kessler Creative, and no regulator or independent investigator has substantiated it. BreachLetter is reporting on the existence of the claim itself, not on a confirmed data breach.
