01. Dark Web & SNS Monitoring

Find out if you're already a target.

We sweep the open web, restricted sites and the dark web for leaked credentials and ransomware-group chatter.

  • Telegram / cybercrime forums
  • paste sites / ransomware blogs
  • illicit marketplaces
◆ Our philosophy
An incident is not a question of if — but when.
— ransomware has shifted from mass-mail to intrusion-based
