  • Check Point Research has identified a shift in the targeting of the Iranian hacktivist proxies which are now extending their cyber operations to include targets in other countries besides Israel, with a particular emphasis on the United States. Moreover, groups such as CyberAv3ngers and Cyber Toufan appear to be adopting a narrative of retaliation in their cyberattacks. They claim to target US entities using Israeli technology, suggesting a strategy of simultaneously targeting both Israeli and US interests.
