AnMed, a nonprofit health system, suffered a data breach in late July that has left some of its systems still offline. Now, an infamous hacker group is claiming credit for the attack in an unusual way. 

The data trove from Medical Computer Business Services includes sensitive patient care information. A hacker group called PEAR had claimed credit for the attack, which occurred in 2025.

DentaQuest, the second-largest dental benefits administrator in the U.S., suffered the record-setting cyberattack in May. A notorious ransomware gang has taken credit for the attack. 

The technology company claims the incident stemmed from a cybersecurity test gone wrong, where its application escaped a closed environment and broke into an external database to complete its task of being an elite hacker

An analysis from cybersecurity consultancy group Omega Systems reveals that most healthcare practices place too much trust in their third-party vendors to secure patient data, neglecting their own IT systems in the process.
