Esse Health’s Cyber Snafu: 263,000 Patients Caught in Data Breach Debacle

Esse Health, the St. Louis medical group, is notifying 263,000 patients of an April cyberattack. While no social security numbers were compromised, personal and health details were swiped. Patients are advised to monitor their credit reports. Meanwhile, Esse Health’s phone systems have resumed operations, so patients can now call to complain about hold music.

Looks like cybercriminals are taking their “patient” game to a whole new level by making patients out of patient data. Esse Health’s systems got a taste of ransomware’s bedside manner, and let’s just say, it wasn’t pretty. With over 263,000 patients potentially playing “Guess the Identity Thief,” this is one doctor’s appointment you don’t want to miss!

  • Patient-facing systems and phone lines were down from April 21 and restored by June 2.
  • Sensitive data including personal and health information was accessed, though social security numbers were reportedly spared.
  • Free identity protection services are offered to affected individuals if they enroll by September 25, 2025.
