Czech researchers are warning of the Chuck Norris botnet, which takes advantage of poorly configured routers and DSL modems.

According to Computerworld, by guessing default administrative passwords, the bot installs itself on routers and modems. It also takes advantage of the fact that many devices are configured to allow remote access. Once Chuck Norris installs itself in the router's memory, it blocks remote communication ports and starts scanning the network for other vulnerable machines.

Users can mitigate the risk by using a strong password on the router or modem. Keeping firmware up-to-date and disabling remote-access services are other ways to address the problem.
