A ransomware group calling itself coinbasecartel claims to have obtained data from Sweet Water Holdings, according to a listing posted on the group’s own leak site and dated August 14, 2026. This claim comes from the group’s self-reported leak-site listing, which is tracked by ransomware.live, a security research platform that monitors ransomware groups’ public extortion sites. Sweet Water Holdings has not confirmed this claim, and no regulator or independent authority has verified it. At this stage, it remains an unverified assertion made by a criminal group seeking attention or leverage, not an established fact.
