US hacker gets five years in the slammer

A US man has been sentenced to nearly five years in prison after he was found guilty of illegally controlling around 400,000 third party PCs for the purposes of launching malware attacks.

Jeanson James Ancheta, 21, from California, rented out space on this zombie network of compromised machines for the sending of spam and malware, and also for launching denial of service attacks.
