Bot software looks to improve peerage
The worm, dubbed Nugache and classified also as bot software, attempts to infect systems through email, America Online's instant messaging network, and network shares on vulnerable computers. Once it compromises a computer, the program uses a seed list of 22 different Internet addresses to establish connections to other victims' computers in a peer to peer network.
The program appears to encrypt--or at least obfuscate--the data it sends to other servers, possibly making it harder for intrusion detection systems (IDSs) to detect the program, according to an analysis posted to a security mailing list by university network administrator Brian Eckman.
