Virus writers at war | Channel Register
April 12, 2006VXers are also turning against each other. Some cybercrims use malicious programs that destroy the software developed by rival groups. Malware authors are fighting each other for control of infected PCs. In early November 2005, for example, an attempt to hijack a botnet was detected that resulted in a network of infected computers changing hands three times in one day. "Criminals have realised that it is much simpler to obtain already infected resources than to maintain their own botnets, or to spend money on buying parts of botnets which are already in use," Kaspersky reports.
