Ethernet communication module for the Modicon Quantum PLC platform, widely used in critical infrastructure. The module exposes HTTP (FactoryCast), FTP, and Telnet services with hard-coded credentials.

Schneider issued firmware updates removing Telnet/WinDriver access but the HTTP and FTP defaults remain in many unpatched deployments.
