Jeanson Ancheta, a 21-year-old southern California hacker, was sentenced yesterday to 57 months in prison for using an automated program to hack into some 400,000 PCs and infect them with pop-up generating adware.
In 2004 and early 2005, Acheta used a customized "rxbot" Trojan horse program to build a "botnet" of compromised PCs, on which he installed ad-delivery programs from two companies: Quebec-based Gammacash, and LOUDcash, which has since been acquired by adware giant 180solutions.
From my article on Ancheta's indictment last November.
Ancheta banked another $3,000 by renting out his botnet to black hats for use in launching denial-of-service attacks or laundering spam.
It's good to see prosecutors going after the people who make the internet a worse place for everyone, but five years is a long sentence for a 21-year-old on his first offense. Ancheta is in custody at the federal Metropolitan Detention Center in Los Angeles.
