Iranian cyberattacks on 'Israel' triple in 2026, official says

• 'Israeli' cyber chief says Iranian cyberattacks tripled during June 2026 compared with the same period last year.
• Critical infrastructure has withstood the attacks, but smaller businesses remain vulnerable.

The number of Iranian cyberattacks targeting 'Israel' has surged sharply this year, according to the head of the country's National Cyber Directorate, as cyber warfare intensifies alongside regional military tensions.

Speaking to German newspaper Die Welt in comments reported by Reuters, National Cyber Directorate Director General Yossi Karadi said the increase followed the start of the US-'Israeli' military campaign against Iran earlier this year.

Karadi said 'Israeli' authorities recorded about 4,800 hostile cyber incidents in June 2026, compared with roughly 1,600 incidents during the same month in 2025, when 'Israeli' military operations against Iran were underway.

"The number of Iranian cyberattacks on 'Israel' has risen sharply," he said, adding that cyber conflict has continued without interruption.

"There is no ceasefire in cyberspace," Karadi said.

According to Karadi, the attacks have targeted systems used by 'Israel's critical infrastructure, central organizations, small and medium-sized businesses, and members of the public.

He said law firms and accounting companies were among the smaller organizations affected by the cyber campaign.

While some of the attackers possess advanced technical capabilities, Karadi said the threat remains manageable.

"Some groups are highly skilled, and we are able to deal with them, but we must take them seriously," he said.

Karadi said 'Israeli' authorities had successfully blocked attacks against critical infrastructure, preventing major disruptions to essential services.

However, he noted that organizations with weaker cybersecurity defenses often suffered severe consequences after being compromised.

"Companies that were easier to breach often ended up having to wipe their computer systems," he said.

The latest figures underscore the growing role of cyber warfare in the confrontation between Iran and 'Israel'. As regional tensions persist, cybersecurity officials warn that digital attacks are likely to remain a key component of the broader conflict, affecting both government institutions and private businesses.
