Evil bot-master Jeanson James Ancheta (aged 20) was sentenced to 57
months (4 1/2+ years) in prison for spreading a bot program which
compromised over 400,000 computers including those used in national
defence and healthcare. The 20-year-old made over $100,000 in affiliate
schemes involving the installation of adware the victims machines—he
also admitted to selling access to his botnets for unknown activities
which could have included DOS attacks and sending of SPAM.
After serving his prison term, Ancheta will be under 3 years of
supervised release in which time his access to computers will be limited.
