Synology is warning that C3RB3R ransomware is encrypting NAS devices running outdated DiskStation Manager (DSM), using flaws patched in December 2024. If your office stores files or backups on a Synology NAS, update DSM now, turn on automatic updates, and make sure the management page is not open to the internet. Keep one backup copy off the NAS.
