Researchers To Debut Botnet-Resistant Coding Techniques
As the botnet epidemic continues to rage, researchers are expanding the scope of their search for new methods to prevent users from becoming unwitting victims of these massive malicious networks. One pair of researchers this week will unveil a new technique they've developed to help Web sites protect users whose machines already have been compromised by bots.
One of the main problems created by botnets is that many users whose PC have been infected by a bot have no idea it's happened. In most cases, there are few outward signs that are noticeable to the average user and so the victims go about their normal online business with no clue that their sensitive data is being packaged up and exfiltrated every day. Botnet traffic typically looks like normal port 80 Web traffic and so it's extremely difficult for victims to identify it and backtrack it to a bot infection.
Most anti-botnet efforts currently focus on finding the network's command-and-control servers and either sinkholing them or working with the hosting providers and law enforcement to take them offline. But this can be a long and laborious process and it's typically only effective on a temporary basis as the attackers often have layers of backup C&C servers ready to come online. The limitations of this approach led to Miami-based researchers to develop several methods that Web site operators can implement to limit the effectiveness of botnets' data extraction methods.

It's nice to see people trying to combat this. Just recently I read how some ISP(s) are now contacting their customers who have infected machines, instead of just ignoring the matter. The pro-active approach taken by people other than the victim seems the best route. As not everyone is security conscious or has legal fully patched operating system(s.)
