Iranian state media alleges that U.S.-manufactured networking equipment from Cisco, Fortinet, Juniper, and MikroTik was deliberately disabled during U.S. military strikes on Isfahan Province. Officials claim the failures could not be attributed to remote cyberattacks given Iran's near-total internet isolation, pointing instead to pre-positioned firmware code or hidden backdoors. U.S. vendors have not confirmed such vulnerabilities, and no independent technical analysis exists. The broader context includes acknowledged U.S. offensive cyber operations, Iranian intrusions into American critical infrastructure targeting PLCs, and ongoing cyber activity by Iran-aligned hacking groups independent of diplomatic developments.
