Cyber officials say Iranian, Hezbollah attacks against Israel tripled since Oct. 7
2025-03-26
[IsraelTimes] Deputy cyber defense chief Nitzan Amar says that the intensity of cyberattacks against Israel has tripled since the outbreak of the Hamas war on October 7, 2023, as Iran and its proxies, including Hezbollah, joined hacking efforts.

“The last year was not a normal year, but a challenging and unique one,” says Amar speaking at the global Cybertech 2025 conference in Tel Aviv. “Ever since the war broke out, we have observed a major amplification in the scope of Iran and Hezbollah malicious activity targeting Israeli entities.”

“Despite our enemies’ efforts, not a single attack targeting an Israeli entity was able to harm neither our national infrastructure, nor the IDF operational freedom to fulfill its missions since October 7,” Amar remarks.

Amar cautions that Israel experienced a 300 percent increase in phishing attacks, the highest ever, seeking to “exploit information, Internet of Things (IoT) devices and disrupt the daily life of Israeli civilians.”

He listed various types of cyberattacks, including rapid exploitation of newly discovered security vulnerabilities, such as “unprecedented-scale DDoS attacks, and cyber intrusions via Managed Service Providers (MSPs).”

“During the war, we began implementing the ‘Cyber Dome’ program to bolster national cyber defense,” says Amar. “We deployed advanced defensive technologies that played a crucial role in mitigating these threats.”
