Black Hat conference: Cisco IOS often targeted by hackers
IT professionals constantly worry about the next computer virus or worm, but there is a greater threat that is often ignored - Cisco routers. While many people think of the router as a hardware device, Cisco IOS, the software that powers the vast majority of routers is vulnerable to attack. Today, at the Black Hat computer security conference in Las Vegas, security expert Michael Lynn demonstrated just how easily a router can be taken over.
Routers are vital to the Internet as they route and prioritize traffic around the world. Using various techniques that we will explain in a later article, Lynn was able to move memory values within a Cisco router, thereby gaining the "enable" prompt or administrator access.
