Iran cyberattacks on Israel surged in 2026, Israeli cyber chief says

June 29 (Reuters) – The number of Iranian cyberattacks against Israel has shot up since the launch of the U.S.-Israeli offensive ​against Iran this year, a senior ‌Israeli security official was quoted as saying on Monday.

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, Israel’s authorities ⁠registered around 1,600 hostile cyber incidents.

During the same month in 2026, the number had jumped to some 4,800 incidents, he told ​the paper.

“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.”

Karadi said the attacks ‌were directed against systems used by Israel’s critical infrastructure, central organisations, small to medium-sized companies and the public, citing law practices ⁠and accounting firms as among the smaller ones hit.

“So far — and hopefully it stays that way — we’ve ⁠managed to ‌fend off attacks on critical ⁠infrastructure,” he said.

Companies that were easier ​to ‌penetrate often ended up having their ​computer systems ⁠wiped, he said, without mentioning any names.

Iran typically denies carrying out hacking campaigns against other countries while reporting attacks on itself.
