ModiPwn: Critical vulnerability in Modicon PLCs bypasses security mechanisms.

See how you can reduce risk and downtime in your environment.

See how you can protect both IT & OT devices.

Armis researchers discovered a new vulnerability in Schneider Electric Modicon PLCs which bypasses security mechanisms. Their research analysis reveals the weak points which lack encryption and proper authentication mechanisms in PLCs commonly found in manufacturing and utility organizations environments.

The deficiencies found lead to vulnerabilities which have been discovered, patched, and re-patched time and time again, in a classic whack-a-mole cycle. This indefensible patchwork can lead to an adversary gaining native code execution.
