Cyber Warfare: Disrupting Iran Amid Military Strikes
TechCrunch reports that U.S. and Israeli kinetic strikes against Iran were accompanied by coordinated cyber and space operations that disrupted Iranian communications and sensor networks ahead of the attack. U.S. military leadership said the operations aimed to disrupt and disorient Iran. Reports describe Israel bombing state-owned IRIB channels and hijacking broadcasts to air speeches by Donald Trump and Benjamin Netanyahu, and using hacked Tehran traffic cameras and penetrated mobile networks as part of operations. Hackers also breached an Iranian prayer app (BadeSaba Calendar) to send messages to users. Multiple news outlets cited in the article characterize these activities as cyber-enabled support for military action and psychological operations.
Reports indicate cyber and space operations were used to support large-scale military action, demonstrating that state-sponsored hacking can materially contribute to kinetic conflict, with implications for infrastructure security, surveillance, media integrity and psychological operations relevant to the technology and advertising ecosystem.

Cyber Attacks and Airstrikes Disrupt Iran Amid Conflict
U.S. and Israel-led airstrikes struck cities across Iran, reportedly killing Supreme Leader Ali Hosseini Khamenei and other top leaders, while coinciding cyberattacks and an extensive internet outage disrupted connectivity nationwide. Users reported a flood of unsolicited notifications on the BadeSaba prayer app containing anti-regime messaging, suggesting the app was compromised. Internet monitoring firms Kentik and Cloudflare reported connectivity collapsed to near-zero levels after strikes. Amazon reported a concurrent outage at its Middle East data center in the UAE, saying objects struck the facility and caused sparks and fire. The conflict risks wider regional disruption — including interruptions to e-commerce routes through the Strait of Hormuz — and raises concerns about impacts to cloud, networking and online services in the region.
Iran Faces Internet Blackout Amid U.S.-Israel Cyber Warfare
Iran entered its fourth day of a near-total nationwide internet blackout, with connectivity at roughly 1% of normal levels, according to NetBlocks. Independent analysts and cybersecurity firms said the outage appears to combine a state-imposed shutdown and external cyber disruption tied to reported U.S. and Israeli cyber operations that accompanied kinetic strikes. Reported cyber incidents include compromises of government-aligned news sites and the BadeSaba Calendar app (reported to have over 5 million downloads), which displayed unauthorized alerts. Security vendors including Flashpoint and CrowdStrike said they observed activity consistent with Iranian-aligned actors conducting reconnaissance and denial-of-service attacks, and U.S. authorities warned of potential low-level retaliatory attacks against U.S. networks. The episode highlights cyber operations as an integrated front in modern hybrid warfare.
Iran's Internet Blackout Enters Second Week Amid Tensions
NetBlocks reported that Iran remains under a near-complete, regime-imposed national internet blackout entering its second week, with internet traffic at roughly 1% of normal levels. The outage followed a week of U.S. and Israeli airstrikes targeting Iran’s nuclear and missile capabilities. Analysts cited in the report say the disruption is likely caused by a mix of state-ordered shutdowns and external cyber disruption; Iran has not officially commented. Cybersecurity vendor CrowdStrike said it is seeing activity consistent with Iranian-aligned threat actors and hacktivists conducting reconnaissance and initiating denial-of-service attacks. Observers warned the communications blackout increases the fog of war for citizens and could presage retaliatory cyber operations.
