**FireEye reports TRITON (TRISIS) has resurfaced at a Middle East critical‑infrastructure site, with attackers using persistent, stealthy reconnaissance and custom tools to access SIS engineering workstations and deploy a TRITON backdoor; FireEye links the toolset to a Russian government research institute and ties the activity to the XENOTIME actor, warning of potential disruptive or destructive consequences.**
