Iranian Cyberattacks on Israel Triple in 2026
In a normal war, diplomats at least mark pauses on paper. In cyberspace, though, attacks run nonstop, with no clear front line. Israel has seen a sharp rise in Iran-linked cyber incidents during the 2026 war.
A Threefold Jump in Hostile Incidents
Yossi Karadi leads Israel’s National Cyber Directorate. He told the Times of Israel that officials logged about 1,600 hostile cyber incidents in June 2025. That was during the first round of the Israel-Iran war. By June 2026, that number had tripled to 4,800 cases.
A Layered Iranian Cyberwar System
Iran’s cyber-war setup, Karadi says, has several layers. Iranian military units sit at its core. So does the Islamic Revolutionary Guard Corps. Both groups run full cyber teams. Below them sit civilian hackers and activists. They attack for belief or for money.
Who the Attacks Targeted
These attacks hit critical systems and large firms. They also hit small and mid-sized businesses, plus everyday users. Karadi named legal and accounting firms among the victims. Israel has managed to defend its key systems so far, he said. Still, weaker firms sometimes lost data. Attackers wiped their systems clean.
Propaganda as a Cyber Weapon
Karadi also pointed to Iranian propaganda online. He called it a separate layer of pressure. That propaganda includes AI-made videos with a Lego-style look. These clips don’t replace direct hacks. Instead, they support cyber operations and help push a military message online.
A Sharp Rise Since 2024
Karadi noted that Israel’s Cyber Directorate handled more than 26,000 cyberattacks in 2025 alone. That figure marks a 55% jump from 2024 levels. Per Microsoft, Israel took 3.5% of all cyberattacks worldwide over the past year. The country ranked third among the most targeted nations.
A Long-Term Defense Plan Through 2030
Israeli officials plan to cut future risk. They’re building a long-term plan for that goal. It should be fully in place by 2030. That plan covers stronger cloud protection. It also covers AI-aware cyber work and prep for quantum computing threats.
