Overview

• The Cybersecurity and Infrastructure Security Agency, FBI, NSA and Defense Department Cyber Crime Center cautioned that state-backed hackers and sympathetic hacktivists may still target U.S. networks despite the Israel-Iran ceasefire.
• Defense contractors with holdings in or ties to Israeli research and defense firms are singled out as facing heightened risk of espionage or disruptive intrusions.
• Officials report no evidence of a coordinated, large-scale Iranian cyber campaign in the U.S. but warn of opportunistic exploits of unpatched software, default credentials and exposed devices.
• The advisory predicts a probable surge in distributed denial-of-service attacks against U.S. and Israeli websites following recent regional strikes.
• Recommended mitigation steps include applying software patches, segmenting networks, enforcing multifactor authentication and isolating critical systems from public internet access.
