Christopher Weatherhead has been found guilty along with Jake Birchall, Ashley Rhodes, and Peter Gibson, who pleaded guilty earlier on. The charges? Conspiring to impair the operation of computers. The four took part in the Anonymous operation that targeted PayPal and Mastercard.

"Weatherhead is a cyber-criminal who waged a sophisticated and orchestrated campaign of online attacks on the computer systems of several major companies," said Russell Tyner, a lawyer from the prosecutors' organized crime division.

The attacks reportedly cost the companies targeted more than $5.6 million in software, sales losses, and extra staffing. Recently, the British police have been investigating hacking collectives Anonymous and LulzSec. We're sure to see more people brought before a judge over similar charges.

The punishment has not yet been dolled out by the judge.
