Dexter is a malware built to steal payment card data from Point-of-Sale systems. A new version was just leaked this is the latest updated build.
What it actually gets
  • Complete Track 1 & Track 2 data from card swipes
  • Card numbers entered manually
  • Billing information (name, address, zip)
  • Session cookies and browser details
 
Latest updates from the leak
  • Modular PHP structure: Now appears as a “payment module” with proper comments
  • Cloud C2: Uses AWS/Azure IPs rotated via domain generation
  • Stealth: Writes logs to 
    Code:
    /tmp/
     with random names, auto-deletes after 24h
  • Anti-detection: Checks for security tools (Monit, OSSEC, cPHulk) before activating
  • Mobile targeting: Now captures mobile checkout forms (Apple Pay/Google Pay proxies)
 
Real defenses
  • File integrity monitoring on 
    Code:
    gateway.php
     and similar payment files
  • Regular checks for unknown 
    Code:
    .exe
     files on web servers
  • Strict FTP/SFTP access with 2FA
  • Memory protection on POS systems (e.g., McAfee POS Endpoint)
  • WAF rules blocking unknown PHP files in payment directories
