FBI announces major cyber incident.

This report covers two high-risk developments: the FBI disclosed a "major incident" in which China‑affiliated hackers are suspected of compromising the agency’s surveillance systems via a commercial ISP/vendor infrastructure—potentially exposing sensitive law‑enforcement data and demonstrating supply‑chain risk—and a multi‑agency CISA advisory warning that Iranian‑affiliated actors are actively targeting internet‑exposed programmable logic controllers (notably Rockwell/Allen‑Bradley) with potential for disruptive, real‑world impacts on critical infrastructure.
