A ransomware group calling itself coinbasecartel claims to have carried out an attack against Crowe, with the claim dated August 19, 2026. This claim originates from an entry on the group’s own dark-web leak site, which was tracked and archived by ransomware.live, a security research platform that monitors ransomware groups’ public leak-site postings. At this stage, the claim is unverified: Crowe has not issued any public confirmation, and no regulator or law enforcement body has corroborated the group’s statement.
What we know — and don’t
- A group identifying itself as coinbasecartel listed Crowe on its leak site with a claimed date of August 19, 2026.
- Crowe operates in a professional services capacity, categorized here under the ‘other’ sector, outside of the standard finance, legal, education, retail, or healthcare classifications.
- The specific types of data the group claims to have obtained — whether client records, employee information, financial documents, or something else — have not been disclosed by the group and have not been confirmed by any independent source.
- There is no independent verification at this time that any system was actually accessed or that any data changed hands.
- This listing was identified and archived via ransomware.live, a platform that catalogs claims made on ransomware leak sites for research purposes; inclusion on such a site does not itself confirm the claim’s accuracy.
What should you do if you have an account with this company?
- Change your password for any account associated with Crowe, and avoid reusing that password anywhere else.
- Enable two-factor authentication (2FA) wherever it is offered, particularly on email and financial accounts.
- Be cautious of unexpected emails, calls, or texts referencing Crowe, especially those urging urgent action or requesting personal or financial details — this is a common follow-on tactic after claims like this surface.
- Review recent account activity and financial statements for anything unfamiliar, and report suspicious transactions promptly.
- Because claims like this can precede identity theft attempts even before any facts are confirmed, consider signing up for a service like Aura or LifeLock to monitor for misuse of your personal information.
- Keep an eye on official communications directly from Crowe rather than relying solely on third-party reports.
