CTB-Locker. Like Cryptolocker But Worse.

Cryptolocker was insanely successful.  It extorted millions of dollars from home and business users.  Like all successful software, upgrades were bound to happen.

Meet CTB-Locker ( a.k.a – Critroni ).

CTB-Locker stands for Curve Tor Bitcoin Locker.  Here are some of the new features at a glance:

  • Hides from authorities by communicating to command and control over the TOR anonymous network.
  • Uses elliptic curve cryptography for encrypting your files.  This encryption is a lot faster than cryptolockers, so once it get’s on your PC or mapped drives it has a better chance of encrypting more files, faster (doing more damage).
  • Accepts payment to unlock your files via bitcoin.
  • Blocking TOR traffic only prevents users from paying, CTB still encrypts the files.

Preventing and mitigating CTB-Locker.

  1. Install a good antivirus (like Kaspersky/Bit Defender).  Keep it patched and updated.
  2. Install Malwarebytes Premium as a second line of defense.  It’s only $25/year.
  3. Always install your Windows updates
  4. Backup your files daily to an external hard drive.
  5. Backup your files via something like Carbonite (if your PC does get hit by something like CTB call Carbonite immediately so they can freeze your backup).
