Cyberwarfare 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.
