• Iran’s National Cyber Security Command alleges Israel has initiated a large-scale cyber offensive targeting critical digital infrastructure.
  • The cyber conflict follows Israel’s "Operation Rising Lion," a military strike in mid-June 2025 that degraded Iran’s nuclear and military capabilities.
  • Escalating cyber warfare risks disrupting Iran’s banking, utilities, and healthcare sectors, with potential spillover effects on global markets.

Cyber Retaliation After Kinetic Strikes

Iran’s claim of a "massive cyber war" by Israel marks a rapid escalation in the long-running shadow conflict between the two nations. The cyber offensive reportedly targets critical infrastructure, including financial networks and public utilities, according to Iranian state media. This comes just weeks after Israel’s "Operation Rising Lion" inflicted significant damage on Iran’s military and nuclear facilities, killing senior officials and limiting Tehran’s conventional response options.

Economic and Strategic Fallout

The cyber campaign risks destabilizing Iran’s already fragile economy, with banking disruptions and energy sector vulnerabilities posing immediate threats. Analysts warn that prolonged attacks could spill into global markets, particularly if oil exports or financial systems are impacted. Meanwhile, Israel faces retaliatory cyber operations from Iranian-linked groups, with recent attacks targeting industrial systems and government databases.

"This is no longer just espionage—it’s disruption warfare," said one cybersecurity expert familiar with the attacks, who requested anonymity due to the sensitivity of the matter. "Both sides are pushing boundaries, and the risk of unintended escalation is high."

A New Normal in Conflict

The shift toward cyber operations as a primary tool of retaliation underscores a broader trend in modern warfare, where digital capabilities compensate for asymmetrical military strength. With Iran’s conventional forces weakened, cyber operations offer a lower-risk, high-impact alternative. Israel, meanwhile, has long prioritized cyber dominance as part of its national security strategy.

Regional tensions remain volatile, with U.S. officials reportedly attempting to mediate behind the scenes. However, neither side shows signs of de-escalation, and experts predict sustained cyber hostilities in the coming months.

Correction: An earlier version misstated the timing of "Operation Rising Lion." The strikes occurred in mid-June 2025, not late May.
