Israel Says Iranian Cyberattacks Tripled Since Last Year as Hacking Groups Coordinate

Iranian cyberattacks against Israel have tripled since last year, according to Yossi Karadi, director general of Israel’s National Cyber Directorate, who spoke to the German newspaper Die Welt. Karadi said Tehran has turned its wide hacking ecosystem into a more coordinated wartime operation.

Karadi said Israeli authorities recorded around 4,800 hostile cyber incidents in June, compared with roughly 1,600 in the same month of 2025. He said the attacks had targeted critical infrastructure, government bodies, businesses and professional services firms.

Karadi said Israel had so far fended off attacks on critical infrastructure, and that its most sensitive networks had remained operational. He said other organisations had seen systems wiped by destructive attacks.

Karadi attributed the rise not only to a greater number of attacks but also to closer cooperation among Iran’s hacking groups, which he said were sharing intelligence, infrastructure and techniques. He also claimed that Tehran had enlisted ransomware gangs and hackers outside Iran to strengthen its cyber operations. He warned that artificial intelligence was speeding up cyber conflict by making attacks easier to launch while giving defenders new tools to detect and respond. He advised organisations to prepare for what an adversary is capable of rather than trying to predict its intentions.

The source notes that Karadi’s figures have not been independently verified. Neither Die Welt nor the National Cyber Directorate published how incidents were counted or what qualifies as a “hostile cyber incident,” and the Directorate did not immediately respond to Resilience Media’s questions. Clear counting methods and open answers from officials are the kind of truthful evidence that allows the public to weigh such claims fairly before repeating them (Proverbs 18:17).

The article places Karadi’s remarks within a wider pattern in which both sides accuse the other of cyberattacks. Public reporting has linked Iran-aligned groups to espionage, phishing and disruptive campaigns, while suspected Israel-linked actors have been blamed for destructive attacks on Iranian banks, fuel systems and industrial sites. Iran has repeatedly denied carrying out offensive cyber campaigns against other countries and has accused Israel and its allies of targeting Iranian networks.
