Hackers have breached the Cisco firewall used by the US government internally, with initial assessments indicating that key infrastructure has been affected. On September 26th, the US Cybersecurity and Infrastructure Security Agency revealed this information. The agency issued an emergency directive requiring federal agencies to investigate Cisco firewall vulnerabilities, identify and eliminate potential intrusions. The specific departments currently under attack and the severity of the breach have not been disclosed, but the agency believes that the attacks have impacted critical infrastructure. In their report, Cisco stated that this attack is highly likely to be carried out by the same group of hackers responsible for the "ArcaneDoor" cyber operation launched in 2024.
