Colorado Behavioral Healthcare Provider Discovers Insider Data Breach
Data breaches have been announced by NAS Recovery Solutions, Entyre Care Massachusetts, Carle Health, and Brown Health Medical Group-MA.
NAS Recovery Solutions
NAS Recovery Solutions, a Lakewood, Colorado-based substance use disorder treatment and behavioral health services provider, has announced a data breach affecting up to 7,000 current and former clients. According to the company’s breach notice, this was an insider breach rather than a hacking incident. The company learned on May 13, 2026, that certain workforce members had downloaded client data without authorization.
The investigation revealed only limited information had been copied, such as first and last names, dates of birth, and telephone numbers; however, since NAS Recovery Solutions is a substance use disorder (SUD) treatment provider, it could be inferred that the individuals were receiving SUD treatment. There are no indications that any other information was obtained by the workforce members. The breach notice does not provide any clue as to why that information was obtained.
NAS Recovery Solutions said it has reviewed workforce access and security controls and is implementing additional safeguards to prevent similar incidents in the future. Additional training has been provided to the workforce on HIPAA and patient privacy, and appropriate corrective action has been taken against the workforce members involved. The sanctions imposed were not disclosed in the notice.

The exposed files were identified on March 12, 2026, and were immediately secured.
