Iranian cyberattacks against Israel have tripled since the launch of the US-Israeli offensive against Iran this year, according to a senior Israeli security official. Yossi Karadi, Director General of Israel's National Cyber Directorate, told German newspaper Die Welt that in June 2025, during Israeli military operations against Iran, Israeli authorities registered around 1,600 hostile cyber incidents. By June 2026, that number had jumped to some 4,800 incidents.
Skilled Attack Groups and No Ceasefire in Cyberspace
“Some groups are very skilled,” Karadi said, according to the German text of the interview. “We can handle them, but we have to take them seriously. Unlike in the kinetic realm, there's no ceasefire in cyberspace.” He noted that the attacks targeted systems used by Israel's critical infrastructure, central organisations, small to medium-sized companies, and the public. Law practices and accounting firms were among the smaller entities hit.
Defense of Critical Infrastructure
“So far — and hopefully it stays that way — we've managed to fend off attacks on critical infrastructure,” Karadi said. However, he warned that companies which were easier to penetrate often ended up having their computer systems wiped, though he did not name any specific victims.
