Iran-linked cyberattacks targeting Israel have nearly tripled since the start of the U.S.-Israeli offensive against Iran, according to a senior Israeli cybersecurity official, highlighting how cyber operations continue to intensify even as military hostilities fluctuate.
Yossi Karadi, director general of Israel's National Cyber Directorate, told German newspaper Die Welt that Israel recorded about 4,800 hostile cyber incidents in June 2026, compared with around 1,600 incidents during the same month a year earlier, when Israeli military operations against Iran were underway.
"Some groups are very skilled," Karadi said in the interview. "We can handle them, but we have to take them seriously. Unlike in the kinetic realm, there's no ceasefire in cyberspace."
According to Karadi, attackers have targeted a broad range of organizations, including critical infrastructure operators, government organizations, small and medium-sized businesses, and the general public. He said law firms and accounting firms were among the smaller organizations that had come under attack.
While cyberattacks have become more frequent, Karadi said Israeli authorities have so far succeeded in protecting critical infrastructure from significant disruption.
"So far — and hopefully it stays that way — we've managed to fend off attacks on critical infrastructure," he said.
He added that organizations with weaker cyber defenses have been more vulnerable, with some suffering destructive attacks that wiped their computer systems, although he did not identify any affected companies.
The figures illustrate the growing role of cyberspace in the broader conflict between Israel and Iran, where cyber operations continue alongside military and geopolitical tensions. Governments and cybersecurity agencies have repeatedly warned that state-backed and affiliated hacking groups increasingly target both public infrastructure and private-sector organizations during periods of heightened conflict.
Iran has consistently denied carrying out offensive cyber campaigns against other countries, while frequently reporting that it has itself been the target of cyberattacks.
