DDoS and Cyber Operations Escalate Amid Israel–U.S. Strikes on Iran
Threat monitoring and situation reporting tied a surge in distributed denial-of-service (DDoS) activity and broader cyber disruption to the escalation of the Israel–U.S. conflict with Iran in late February 2026. NSFOCUS reported sustained DDoS targeting of Iranian IP space following internal unrest and rising U.S.–Iran nuclear tensions, describing both botnet-driven floods and reflection/amplification techniques against 259 Iranian IPs, including government, news, and network-infrastructure entities. As kinetic events intensified—particularly after Israel announced strikes on Iran—reporting described a sharp increase in DDoS activity and subsequent Iranian network control measures, including an internet shutdown intended to reduce exposure to anticipated cyberattacks.
CloudSEK characterized the period as a shift into hybrid conflict, citing coordinated Israeli–U.S. strikes (described as Operation Roaring Lion/Epic Fury) alongside what it called a major cyber campaign contributing to a near-total Iranian internet blackout and disruption to government services, media, and parts of energy and aviation. In parallel, Russia’s internet regulator Roskomnadzor and the Russian Defense Ministry reported a separate “complex multi-vector” DDoS incident that briefly disrupted access to multiple Russian government websites and related infrastructure (including the Main Radio Frequency Center), with traffic attributed to servers/botnets across several countries; no actor claimed responsibility. While DDoS is a common tactic in geopolitical crises, the Russian incident appears operationally and geographically distinct from the Iran-focused escalation reporting.

Cyber and information operations intensify amid US-Israel strikes on Iran under “Operation Epic Fury”
US and Israeli military action against Iran under **“Operation Epic Fury”** has been accompanied by heightened cyber activity and public acknowledgment of offensive cyber operations. Reporting indicated a surge of pro-Iranian activity including **DDoS attacks**, attempted compromises, and targeting of **critical infrastructure**, with researchers warning that Iranian state-linked actors tied to the **IRGC** and **MOIS**, as well as aligned hacktivists, are likely to sustain retaliatory operations aimed at economic, reputational, and potentially physical disruption. Separately, reporting alleged Israeli intelligence conducted long-running surveillance by compromising **Tehran traffic cameras**, exfiltrating encrypted video and telemetry to servers outside Iran to build “pattern of life” intelligence on senior leadership movements. The Pentagon also elevated the visibility of cyber as a warfighting domain, with the Chairman of the Joint Chiefs describing coordinated **space and cyber** effects used to “disrupt, degrade, and blind” Iranian communications and sensor networks, though without operational detail. In parallel but unrelated to the Iran conflict, Russia’s internet regulator **Roskomnadzor** and the Russian Defense Ministry reported a “complex multi-vector” **DDoS** incident that temporarily disrupted multiple government sites, with traffic attributed to botnets and servers across several countries and continued user-reported instability after initial containment.

Cyber Operations Escalate Following US-Israeli Strikes on Iran
Military strikes by the United States and Israel against Iranian targets on **February 28, 2026** were followed within hours by a sharp escalation in cyber activity across the Middle East. Reporting describes widespread **DDoS attacks, website compromises, defacements, and breach claims**, with more than 150 hacktivist incidents reportedly claimed in the first two days of the crisis. Iranian connectivity was heavily disrupted, including outages affecting **IRNA**, while **Tasnim News** was reportedly compromised and displayed anti-regime messaging. The most affected sectors were identified as **government, aerospace and defense, and technology**, and regional states including **Israel, Kuwait, Jordan, Bahrain, Qatar, and the UAE** saw elevated cyber pressure. The surge also expanded beyond immediate regional targets, with security reporting warning that the conflict was driving attacks against global commercial sectors such as **travel, hospitality, and energy**. One cited example was a **March 11** claim by **Handala**, a hacktivist group alleged to have ties to Iranian intelligence, that it had conducted a large-scale **data-wiping attack** against medical technology company **Stryker**, allegedly destroying several terabytes of data. Additional reporting noted unconfirmed concerns that Iranian-linked actors could target the physical and digital infrastructure of major U.S. technology firms. The activity reflects a broader pattern of **geopolitically motivated cyber operations** acting as a force multiplier alongside kinetic conflict, rather than a standalone marketing or advisory narrative.

Iran–Israel–US conflict triggers rapid hacktivist mobilization and elevated DDoS risk to government and critical infrastructure
Cyber activity surged immediately following joint **U.S.–Israel strikes on Iran** (described as *Operation Epic Fury*), with reporting indicating a fast-moving “cyber swarm” of hacktivists and aligned collectives conducting disruption, influence messaging, and broad cyber claim activity within hours of the kinetic events. A day-by-day Telegram-focused timeline described early **DDoS campaigns against Israeli government sites** expanding into a wider coalition of **pro-Iranian, pro-Palestinian, and Russian-aligned** groups targeting additional regions and sectors, including Gulf states, Europe, and the U.S., with increasing attention on **critical infrastructure**; examples cited include claims of DDoS disruption against Israeli commercial, defense-adjacent, and energy-related entities (e.g., an oil company and an advanced defense firm), sometimes accompanied by third-party availability “verification” links. U.S. state and local governments were separately warned by **MS-ISAC** to expect heightened “low-level” activity—particularly **DDoS**—in the wake of the Iran-related escalation, and were urged to harden internet-facing and cloud services (e.g., remediation of critical/cloud infrastructure, use of firewalls/CDNs, and reducing exposed employee/organizational data). In parallel, a critical-infrastructure-focused interview tied to an upcoming OT security summit reiterated that energy, water, pipeline, and ICS environments face persistent probing by state adversaries and that “low-cost entry” cyber operations can be used to test and disrupt mission-critical systems; while not specific to the Iran conflict, it reinforces the broader risk context for OT operators amid heightened geopolitical tensions.
