A recent CT scan of an O.MG pen testing USB-C cable has uncovered hidden electronics that could allow an attacker to take control of any device plugged into it.
The scan, conducted by Lumafield, revealed advanced components such as a microcontroller, antenna, and a secondary die, which could easily evade traditional detection methods like X-ray scans.
Created by security researcher Mike Grover, the O.MG cable is designed for penetration testing, enabling security experts to assess vulnerabilities in devices.
It features functions such as keystroke and mouse injection, keylogging, and geo-fencing, making it a powerful tool for red teamers and awareness training.
The discovery underscores the risks of supply chain attacks, where malicious electronics can be inserted into consumer products unnoticed.
While cables like these are expensive, starting at $119.99, it’s important to remain cautious when purchasing electronics.
Experts recommend buying cables from trusted sources and avoiding public USB charging ports to reduce the risk of device compromise.
