Synology NAS Devices Targeted in Ransomware Attacks Exploiting Patched DSM Flaw

Synology is urging customers to update the DiskStation Manager (DSM) software powering its Network Attached Storage (NAS) devices after observing active ransomware attacks. Threat actors are exploiting vulnerabilities patched in late 2024 to target outdated instances and deploy payloads such as the C3RB3R ransomware. Users are advised to immediately apply software updates and disable unnecessary exposure of administrative interfaces to the internet.
