We have come across a botnet worm spreading around called "psyb0t". It is notable because, according to my knowledge, it:

* is the first botnet worm to target routers and DSL modems
* contains shellcode for many mipsel devices
* is not targeting PCs or servers
* uses multiple strategies for exploitation, including bruteforce username and password combinations
* harvests usernames and passwords through deep packet inspection
* can scan for exploitable phpMyAdmin and MySQL servers
