US Warns of Iranian Cyber Threat to Infrastructure

U.S. security agencies, including CISA, FBI, NSA, and the Defense Cyber Crime Center, have jointly warned of heightened cyberattack risks from Iranian state-sponsored and affiliated hackers targeting critical infrastructure amid recent geopolitical tensions. The alert follows U.S. involvement in Israeli military actions against Iran's nuclear sites and highlights defense contractors with Israeli ties as particularly vulnerable. These Iranian-linked hackers exploit poorly secured networks and have escalated activities such as website defacements and data leaks. While there is no evidence yet of a coordinated campaign, agencies caution that DDoS and hack-and-leak operations could increase in response to ongoing events. Critical infrastructure operators are urged to bolster security by patching software, updating credentials, and enabling multifactor authentication. The warning comes as Israel and Iran maintain a ceasefire and continue negotiations.
