### AI overview

Synology warned that attackers are using a vulnerability patched in December 2024 to target NAS devices running outdated DiskStation Manager (DSM), encrypting data and demanding ransom. It urged users to update DSM immediately and enable automatic updates. The article also advises blocking Internet access to the management web interface, and notes that Synology had not provided information about fixes for several other cited vulnerabilities. Reports from affected customers described a ransom note directing victims to buy "C3rb3r Decryptor" and encrypted files renamed with a .L0CK3D extension. The excerpt does not establish how many exposed devices remain vulnerable.
