A ransomware group calling itself Direwolf claims to have targeted Colla Health, according to a listing on the group’s dark-web leak site dated August 15, 2026. This claim comes from the group’s own extortion-site posting, which has been tracked and archived by ransomware.live, a security research platform that monitors ransomware groups’ public leak sites. At this time, Colla Health has not issued any public confirmation of an incident, and no regulator has verified the group’s claim. It should be treated strictly as an unverified assertion by a criminal group rather than an established fact.

What should you do if you have an account with this company?
- Change your password for any account with Colla Health, and avoid reusing that password anywhere else.
- Enable two-factor authentication (2FA) on your account if it is offered and not already active.
