A ransomware group calling itself Genesis claims to have carried out an attack against Interim HealthCare (Oklahoma and Tulsa), with the claim dated August 10, 2026. This claim was posted on the group’s own dark-web leak site and has been tracked by ransomware.live, a security research platform that monitors ransomware groups’ public leak sites. At this time, the claim has not been independently verified, and it should be treated as an unconfirmed statement from 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 associated with Interim HealthCare, and avoid reusing that password on other sites.
- Enable two-factor authentication (2FA) wherever it is offered, particularly for email, financial, and healthcare portal accounts.
- Be cautious of unexpected emails, texts, or calls referencing Interim HealthCare, especially those urging urgent action or requesting personal information — these could be phishing attempts capitalizing on this claim.
- Monitor your financial and insurance statements for unfamiliar activity, and consider placing a fraud alert or credit freeze if you notice anything suspicious.
- Since healthcare-related claims can sometimes involve personal identifiers, using a service like a service like Aura or LifeLock to watch for signs of identity misuse can add an extra layer of protection while this situation remains unconfirmed.
