The Israeli military says it detected over 600 cyberattacks attributed to Hezbollah during the conflict, describing cyber operations as a "silent war" that continues across ceasefires.
The Israeli military has identified more than 600 cyberattacks linked to Hezbollah against Israeli targets during the war, according to reporting by Israeli journalist Netsan Shapira. The attacks represent what Iran and Hezbollah describe as a "silent war" that allows them to continue targeting Israel even when direct military confrontation subsides.
Hezbollah, working with Iranian backing and other armed groups active in Lebanon, has expanded its offensive cyber capabilities in recent years, the Israeli military said. The military's cyber defence division, operating within the communications and information technology branch, is tasked with countering these operations in coordination with other security agencies.
Israel has recorded more than 2,500 cyberattack attempts since October 7, according to figures cited in the report. The military's cyber teams operate specialised operations rooms, "red teams" and dedicated intelligence systems to manage these incidents.
The character of the threat has shifted qualitatively in recent years with the integration of artificial intelligence into cyber warfare. AI can be used to identify security vulnerabilities and in some cases to assist in executing attacks themselves, the military said.
The advancement has raised the capability threshold for attackers. Organisations previously considered to have limited capacity can now conduct more sophisticated operations using AI tools. Cyber attacks themselves have become higher quality and more complex.
The Israeli cyber defence division said it is developing advanced capabilities and training programmes to match the evolving threat landscape and accelerating technological change. The military said it has not recorded any cyber successes of "significant importance" by Hezbollah to date.
