US security agencies, including the National Security Agency (NSA) and the Federal Bureau of Investigation (FBI), have issued warnings about Russian military intelligence hackers targeting home internet routers. These hackers, linked to the GRU (Main Intelligence Directorate of the General Staff of the Armed Forces of the Russian Federation), exploited known software vulnerabilities in thousands of routers, including popular TP-Link models. This allowed them to manipulate Domain Name System (DNS) settings, redirecting internet traffic through malicious servers to harvest sensitive information such as passwords and emails. The operation, known as 'Operation Masquerade,' spanned over 20 states and targeted government and critical infrastructure networks. In response, the FBI took proactive measures by remotely removing malicious settings from compromised routers, ensuring that users' personal data remained secure. The agencies stress the importance of router security, noting that a significant percentage of users have never changed their default passwords or updated their firmware. They recommend users reboot their routers weekly, update firmware, and disable remote management features to enhance security.
