BabLock Ransomware: Signs, removal steps, and prevention tips

BabLock Ransomware

What it is (in plain words):
BabLock is ransomware that breaks into Windows and Linux systems, scrambles (encrypts) your files, and demands payment to unlock them. It typically goes after small and mid-size businesses where one infected PC can quickly disrupt the whole office.

How it spreads:

  • Phishing emails and booby-trapped attachments

  • Cracked/unknown software and malicious installers

  • Exposed or weakly protected RDP/VPN access

  • Unpatched software vulnerabilities and supply-chain downloads

Signs to watch for:

  • Files won’t open and new extensions appear

  • Ransom notes in many folders

  • Sudden CPU/disk spikes; security tools disabled

  • Backups or mapped drives also encrypted

If it happens, do this now:

  1. Isolate affected machines from the network (unplug/disable Wi-Fi).

  2. Do not delete notes or logs—they help recovery and investigation.

  3. Check offline backups and prepare clean rebuilds.

  4. Rotate passwords (especially admin/domain) from a clean device.

  5. Call IT/IR support; consider reporting to local authorities.

Prevent it:

  • Keep systems and apps patched; remove unused remote access.

  • Enforce MFA on RDP/VPN and limit admin rights.

  • Use reputable EDR/anti-malware and email filtering.

  • Maintain offline, tested backups (and practice restore drills).

  • Train staff to spot phishing.
