Harvesting Data on the Xarvester Botmaster

August 6, 2012

In February, I published the results of an investigation into the identity of the man behind the once-infamous Srizbi spam botnet. Today’s post looks at the individual(s) likely involved in running the now-defunct Xarvester botnet, a spam machine that experts say appeared shortly after Srizbi went offline and shared remarkably similar traits.

Consumer demand for cheap prescription drugs sold through spam-advertised Web sites shows no sign of abating, according to a new analysis of bookeeping records maintained by three of the world’s largest rogue pharmacy operations.

Researchers at the University of California, San Diego, the International Computer Science Institute and George Mason University examined caches of data showing the day-to-day finances of GlavMed, SpamIt, and Rx-Promotion, shadowy affiliate programs that over a four-year period processed more than $170 million worth of orders from customers seeking cheaper, more accessible and more discretely available drugs. The result is is perhaps the most detailed analysis yet of the business case for the malicious software and spam epidemics that persist to this day.

Global spam volumes have fallen precipitously in the past two months, thanks to a cessation of junk e-mail from Rustock — until recently the world’s most active spam botnet. But experts say those behind Rustock haven’t gone away, but have merely shifted the botnet’s resources toward other money-making activities, such as installing spyware and adware.
