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
