The data breach lawyers at The Lyon Firm are investigating a recently reported data breach at PEMHS, operating as Eleos Wellness, a mental health and substance abuse treatment provider based in Florida.

What Happened at Eleos Wellness?

The Eleos security breach stems from unauthorized actors allegedly gaining access to PEMHS’s systems, potentially compromising a large amount of protected health information (PHI) and personally identifiable information (PII) of patients. While the exact number of individuals impacted and full scope of data breached remains under investigation, the attack is believed to have affected electronic records, possibly including names, Social Security numbers, treatment histories, and contact details.

Eleos Wellness, operating under PEMHS (Pinellas County Emergency Medical Services, Inc.), is a Largo, Florida-based healthcare provider specializing in mental health and substance abuse treatment. The entity offers psychiatric care, counseling, addiction recovery programs, and dual-diagnosis treatment for those with co-occurring mental health and substance use disorders across Pinellas, Pasco, and Manatee counties.

PEMHS has engaged forensic experts to assess the damage and will notify affected individuals with data breach notification letters. The healthcare industry is frequently targeted in ransomware and cyberattacks because they offer huge data troves—PHI and PII are goldmines for identity theft and fraud, fetching high prices on the dark web. Weak cybersecurity, reliance on outdated systems, and third-party vendors create exploitable gaps.
