I was reading about bot-nets and was wondering why it is not possible to find the origin of these nets and route them out by identifying the origin computer which sets these up ?
I perhaps don't understand them very much so pardon my naive question.
Theoritically all traffic that originates from every computer has to go through an ISP, a bunch of intermediate routers and finally reach it's destination host. So if the ISPs monitor incoming and outgoing addresses they should be able to tell which IP addresses is making all these connections to a large number of destinations or some such heuristic...
In general these backbone providers and ISPS together essentially know where the connections from each computer go, so why not follow them ?
