"The botnet, which appears to be larger than the infamous Storm
botnet was in its heyday, has infected machines from some 77
government-owned domains -- 51 of which are U.S. government ones,
according to Ophir Shalltin, marketing director of Finjan, which
recently found the botnet. Shalltin says the botnet is controlled
by six individuals and is hosted in Ukraine.
"Aside from its massive size and scope, what is also striking
about the botnet is what its malware can do to an infected machine.
The malware lets an attacker read the victim's email, communicate
via HTTP in the botnet, inject code into other processes, visit
Websites without the user knowing, and register as a background
service on the infected machine, for instance. The bots communicate
with their command and control systems via HTTP."
