FBI Warns: End-of-Life Wi-Fi Routers Pose Major Cybersecurity Threats

The Federal Bureau of Investigation (FBI) has issued a warning regarding the cybersecurity risks associated with older Wi-Fi routers. The advisory specifically targets devices manufactured in the late 2000s and early 2010s that are considered end-of-life by their manufacturers. These devices no longer receive software updates or security patches, making them vulnerable to cyberattacks.

The FBI highlights that older, end-of-life Wi-Fi routers, particularly those from the late 2000s and early 2010s, are highly susceptible to cyberattacks due to a lack of ongoing security support.

Vulnerabilities and Exploitation

When routers reach their end-of-life status, they become susceptible to exploitation due to unpatched security flaws. The FBI reports that threat actors are leveraging these known vulnerabilities to perform several malicious activities, including:

• Installing malware on the devices.
• Gaining root access to the routers.
• Integrating the compromised devices into botnets, which are networks of machines used for coordinated attacks or to sell proxy access to other criminal entities.

Affected Router Models

The FBI identified several legacy router models as particularly vulnerable, primarily from Linksys:

• Linksys E1200 (2011)
• Linksys E2500 (2011)
• Linksys E4200 (2011)
• Linksys WRT320N (2009)
• Linksys M10 (2010)
