Analytic 1914

Real-time monitoring identifies a browser process on an Industrial Control System (ICS) workstation spawning an unexpected child process immediately following navigation to an external website, particularly a vendor support or software-download site. Documented Havex precedent: adversaries compromised legitimate ICS vendor websites to serve trojanized software downloads. OT operational-fidelity gate: Alert only when the account/device/session violates the approved identity + source host/jump path/zone policy and is corroborated by access to a protected OT asset, execution, configuration change, or another security-relevant follow-on event. Suppress approved shift activity, vendor support, break-glass use, commissioning, and documented remote-access windows.
