A ransomware group calling itself direwolf claims to have carried out an attack on AliveCor, Inc., with the claim dated August 10, 2026. This claim comes from an entry on the group’s own leak-site listing, which is tracked and cataloged by ransomware.live, a security research platform that monitors public leak sites run by ransomware groups. At this time, the claim is unverified — AliveCor has not issued a public statement confirming or denying an incident, and no regulator or independent investigator has corroborated it. BreachLetter is reporting on the existence of this claim, not on a confirmed breach.

What should you do if you have an account with this company?
- Change your password for any AliveCor account or related app login, and avoid reusing that password elsewhere.
- Enable two-factor authentication (2FA) on your account if it is available and not already active.
- Be alert for phishing emails, texts, or calls that reference AliveCor, your health data, or account details — attackers sometimes use claimed breaches to craft convincing scams.
- Monitor your financial and healthcare-related accounts for any unusual or unauthorized activity.
- Consider signing up for an identity monitoring service such as a service like Aura or LifeLock to get alerted if your personal information appears in places it shouldn’t.
- Keep an eye on official communications from AliveCor for any updates regarding this claim.
