Updating routers with the latest firmware is a frequent recommendation to improve network security. When it comes to home routers, though, the latest updates won’t help you much. According to a study by Germany’s Fraunhofer Institute for Communication (FKIE), vendors have failed to fix hundreds of vulnerabilities in their consumer-grade routers, leaving people exposed to a wide range of attacks.
The FKIE examined 127 routers spanning seven large vendors and found security flaws in all of them. It called its results “alarming.”
“Many routers are affected by hundreds of known vulnerabilities,” it warned. “Even if the routers got recent updates, many of these known vulnerabilities were not fixed.”
