Update: Iranian-U.S./Israeli Hostilities Lead to Increased Threat Landscape

Assura details proactive threat-hunting and detection focused on Iranian-sponsored activity following increased hostilities, identifying multiple APT actors (Educated Manticore, Void Manticore, Mango Sandstorm, Charming Kitten, Static Kitten, MuddyWater), compiling IP/CIDR IOCs, and performing retrospective analysis that generated alerts for attempted connections on high-numbered ports (no successful intrusions). The post notes two attacks attributed to MuddyWater against U.S. airports in early 2026, describes blacklisting of malicious CIDR blocks, shares findings to OTX, and provides operational recommendations (MFA, external exposure review, phishing awareness, IR readiness).
