Last year we wrote about how rival online scammer gangs had their botnets fighting each other by disabling trojans of competing botnets on their computers -- but it appears that some researchers have a different idea for creating a "good" botnet to fight the "bad" botnets being used for denial of service attacks (found via Slashdot). This is quite different than some older proposals to create "good worms" that go about automatically patching infected machines (which are wide open to abuse). Instead, the idea is rather creative. It involves setting up a distributed system of computers that effectively act as a way station for connect requests -- which then wait for the actual server to request the inbound requests. This prevents the server from being overloaded (though, I would imagine it could slow down access somewhat). Either way, it's nice to see efforts under way to stop such zombie botnets. Hopefully someone isn't sitting on a patent for such an idea and waiting to sue, like we've seen with other security measures.
