AMEOS Group, a major healthcare network in Central Europe, has disclosed a security breach that may have compromised sensitive information of customers, employees, and partners. In response, the organization has shut down its IT systems and engaged external experts to investigate the incident, which remains under investigation with no evidence of data dissemination so far.

Cyberattacks surged during the summer of 2025, with ransomware groups targeting healthcare and retail sectors, while nation-state actors engaged in geopolitical cyber activities. Major incidents included the rise of the Interlock and Qilin ransomware groups, significant data breaches in retail, and the exploitation of Microsoft SharePoint vulnerabilities in a widespread campaign. Organizations are urged to improve their defenses by patching vulnerabilities, training personnel, and monitoring for lateral movement post-intrusion.
