Hostile online activity linked to Iran has surged since the U.S.-Israel campaign against Iran began this year, with detected malicious cyber events nearly tripling in June compared to the previous year. Yossi Karadi, head of Israel’s National Cyber Directorate, disclosed the sharp increase in an interview, highlighting the escalating digital threat landscape amid ongoing regional tensions.

Surge In Malicious Cyber Events

Israeli authorities counted approximately 1,600 malicious cyber events in June 2025 during Israeli military activity involving Iran. The tally for June 2026 rose to roughly 4,800, representing a significant year-over-year jump. Karadi noted that some attacker groups are highly skilled, emphasizing the need for serious vigilance.

Impact On Targets

The attempted intrusions have targeted a broad spectrum of victims, ranging from essential services and major institutions to smaller businesses and individual users. Professional-services firms, including law offices and accounting shops, were among the smaller organizations that came under pressure. Karadi stated that less-protected organizations sometimes saw their systems erased after being breached, though specific companies were not identified.

Defense Of Critical Infrastructure

Despite the volume of attacks, Israel has to date prevented successful hits on key infrastructure systems. "So far — and hopefully it stays that way — we’ve managed to fend off attacks on critical infrastructure," Karadi said. He described the cyber realm as one without a ceasefire, unlike kinetic warfare, underscoring the persistent nature of the threat.
