Dozens of ZeuS Botnets Knocked Offline.
Security experts are tracking a massive drop in the global number of control servers for various ZeuS botnets that are online, suggesting that a coordinated takedown effort may have been executed by law enforcement and/or volunteers from the security research community acting in tandem.
Sold for anywhere from $300-$2,000 in shadowy underground forums, ZeuS is a software kit that allows criminals to set up distributed networks of hacked PCs, usually for the purposes of siphoning user names, passwords and financial data from victim computers. A criminal operating a ZeuS botnet can control the systems from afar using a central “command and control” (C&C) server, and it is not uncommon for a single ZeuS C&C server to control tens of thousands of infected hosts. In most cases, the infected PCs continuously upload the victim’s personal data to so-called “drop servers,” or data repositories online that are specified by the criminal controlling the ZeuS botnet.
