Owners of Linux-based routers are in for a “reverse treat” – a botnet called Chuck Norris attacks these devices.
PCWorld reports the following:
Once installed in the router’s memory, the bot blocks remote communication ports and begins to scan the network for other vulnerable machines. It is controlled via IRC.
Because the Chuck Norris botnet lives in the router’s RAM, it can be removed with a restart.
So: change that default password, folks!
