Iran tried to penetrate Israeli military networks
During the War Against Iran: Tehran Launched Dozens of Cyberattacks on Israel—Including Attempts to Breach Home Front Command Systems

During Israel’s 12-day military campaign against Iran, the cyber arena played a significant, though less-publicized, role. While Israeli cyber units—according to foreign reports—targeted Iranian banking and crypto systems linked to the Islamic Revolutionary Guard Corps, Iran too launched dozens of cyberattacks against Israel, revealed this morning by veteran Israeli analyst Doron Kadosh.
According to senior IDF officials, Iran had some “localized successes,” but these were limited to civilian subcontractor companies that provide services to Israel’s defense apparatus. No military systems were penetrated, and no meaningful damage was inflicted on the IDF’s operational continuity.
These targeted companies are part of the Defense Ministry’s supply chain and were seen by Iran as more vulnerable cyber targets than military systems, which are protected by significantly more robust defense layers. The aim was to disrupt operations or extract sensitive data.
Iran also attempted to breach and attack Israel’s Home Front Command systems. Had they succeeded, the consequences could have been severe—potentially disrupting rocket warning alerts and disabling civilian notification systems. However, none of these attempts were successful, and the Home Front Command operated at full capacity throughout the campaign.
In response to the cyberattacks, Israeli security bodies—the IDF, Shin Bet, and the National Cyber Directorate—contacted affected companies and offered assistance. In some cases, IDF Cyber Defense Brigade personnel even accessed the companies’ systems directly to help contain and neutralize the Iranian intrusions. The government also helped reinforce their cyber defenses—an effort referred to as "raising the walls."
A senior Israeli security official told *Galei Tzahal*:
“Iran is a serious adversary in this domain as well, but they’re not a cyber superpower like we are. The IDF’s cyber fortifications are strong, but as with any physical border, cyber defenses will inevitably be breached. Our mission is to identify these weak points in advance and better prepare for the next round against Iran. Because while the missiles and airstrikes may have stopped—the cyber war never ends.”
