Researchers say they’ve come up with ways to make infected machines useless to botnet operators. They studied samples of Zeus and SpyEye Trojans, then wrote code for Web servers that mitigates these botnets. Zeus uses POST-logging to glean valuable data from Web sessions from the machines it infects. Their methods don’t prevent a bot infection, but rather stymie the botmaster from ultimately gathering any useful information from the victim. They hope to convert these methods into software modules for the OWASP Enterprise Security API.”]
