Occasionally, I run across a computer virus or a worm that manages to constantly top itself with new variants. After nearly 20 variations, the Sober virus still amazes me. Beginning January 6, 2006, the Sober virus will launch another wave of e-mail attacks on the Internet. How do we know this? Thanks to diligence of Mikko Hypponen and his antivirus research staff at F-Secure, we know that within an encrypted part of the latest Sober worm is a complex set of instructions detailing several dates on which Sober is likely to make another attack; and thanks to another set of researchers at iDefense, we think January 5 or 6, 2006, either a Thursday or a Friday--just in time to fill everyone's e-mailbox with junk over the weekend--is the most likely of those dates for that attack to occur.

The "bootstrap" effect
Imagine sending a very large and sophisticated virus over e-mail--your ISP or company would certainly stop it dead at the gateway. So, virus writers have started sending out smaller versions that merely infect. Once installed, the small virus then opens a backdoor to call out to the predetermined Web server IP address from which it then loads a more sophisticated version of itself (or it transforms the infected PC into a conduit for spam, pornography, or a host of other malicious uses). If the small virus downloaded the larger code upon infection, there would be a collision of newly infected machines and second-wave infections, so virus writers have started delaying the second wave by several days or even several weeks. ...
