Yossi Karadi, director-general of Israel’s National Cyber Directorate, claims Iranian cyberattacks against Israel have surged since the launch of the US-Israeli war on Iran, Al Jazeera reports.

He told German newspaper Die Welt that hostile incidents rose from about 1,600 in June 2025 to roughly 4,800 in June 2026.

“Some groups are very skilled,” Karadi said. “We can handle them, but we have to take them seriously. Unlike in the kinetic realm, there’s no ceasefire in cyberspace.”

The attacks targeted critical infrastructure, large organisations and smaller businesses such as law firms and accounting practices. Companies that were easier to penetrate often had their systems wiped entirely, he claimed.
