use of electronic warfare during the 2026 Iran war
Cyberwarfare during the 2026 Iran war is the digital and information operations conducted by Israel, the United States, Iran, and affiliated hacktivist groups as part of the ongoing 2026 Iran war that began on 28 February 2026.
The cyber domain played a supporting role in the initial kinetic strikes, with coordinated U.S.–Israeli operations reportedly disrupting Iranian command, control, and sensor networks ahead of airstrikes. Israel also conducted large-scale information operations, including the compromise of a popular Iranian prayer app and state broadcasting channels. Iran and pro-Iran hacktivists threatened and claimed retaliatory cyberattacks, though widespread internet blackouts inside Iran limited their effectiveness.
Background
The Iran war erupted on 28 February 2026 when Israel and the United States launched coordinated airstrikes (codenamed Operation Roaring Lion and Operation Epic Fury) targeting Iranian leadership, nuclear facilities, and military sites, including the assassination of Supreme Leader Ali Khamenei. Cyber and electronic-warfare capabilities were integrated into the opening phase to disrupt Iranian command-and-control, communications, and sensor networks.
Iran has maintained an active state-sponsored cyber program for years, and has previously been both perpetrator and victim of state-sponsored cyber operations (notably Stuxnet in 2010) with documented capabilities in wiper malware, distributed denial-of-service (DDoS) attacks, and espionage against critical infrastructure. Prior to the 2026 conflict, Iran had conducted cyberattacks on financial institutions and election-related targets, and maintained proxy hacktivist networks for plausible deniability.
