If your office files live on a Synology NAS, check its software version today.
Security researchers are tracking a ransomware strain called C3RB3R that has been encrypting Synology NAS devices since early October. It gets in through critical flaws in DSM, Synology's operating system, and it doesn't need a password to do it. Locked files get a ".L0CK3D" extension, and the attackers leave a ransom note behind.
Synology released the fix back in September, so the devices getting hit are mostly ones nobody updated. The ransomware also encrypts any backups stored on the same NAS. A backup that sits right next to the original is not a backup.
What we recommend:
• Update DSM now and turn on automatic updates
• Don't expose the NAS directly to the internet. Use a VPN for remote access
• Turn on 2FA and disable the default "admin" account
• Keep at least one backup copy off the device and disconnected
If you're not sure who's responsible for patching the box in your closet, that's worth sorting out this week.

💾 When was the last time you actually tested your backups?
Most businesses have "a backup." Far fewer have one they've ever tried to restore from. Ransomware, a dead hard drive, a spilled coffee or an accidental "delete all" can stop a business cold, and the worst time to find out your backup doesn't work is the day you need it. With the year winding down, now is a great time for a quick check-up:
✅ Follow the 3-2-1 rule: 3 copies of your data, on 2 different types of storage, with 1 copy offsite or in the cloud.
✅ Do a test restore. Pick a few files (or a whole folder) and actually bring them back. If it's slow or confusing, better to learn that now.
✅ Don't forget the cloud. Microsoft 365 and Google Workspace keep your email and files running, but they aren't a complete backup plan on their own. Check what's covered and for how long.
✅ Keep one copy disconnected or locked from changes. Ransomware can encrypt backups that are always plugged in or syncing.
✅ Write down who does what. If your server, POS or camera system went down tomorrow, who calls whom, and how long can you afford to be offline?
A backup you've never tested is really just a hope. 🙂
