GoKawiilSynology warns C3RB3R ransomware is hitting unpatched NAS devices
Synology issued an advisory saying threat actors are exploiting a vulnerability patched in December 2024 to deploy C3RB3R ransomware against NAS devices still running outdated DSM software. The company did not name the specific flaw but pointed to a November 2024 advisory covering three vulnerabilities allowing code execution and file read/write access. Synology is urging customers to update DSM immediately, enable automatic updates, and block internet access to the management web interface.
GoKawiil's interpretation of the reporting above, not reported fact.
Synology's decision to issue a public attack warning is notable since the company has done so only once before, in 2019, suggesting the current campaign may be unusually active or damaging. The advisory highlights a recurring risk for NAS users: devices left unpatched and exposed to the internet remain prime ransomware targets, and attackers often weaponize vulnerabilities months after patches are released.
- Synology confirms active C3RB3R ransomware attacks exploiting a vulnerability patched in December 2024.
- Users on outdated DSM versions across multiple product lines are urged to update immediately.
- Synology recommends blocking internet access to the DSM management interface as an added precaution.
