A jury has convicted 22-year old Anonymous hacktivist Christopher Weatherhead for playing a lead role in organizing a series of distributed denial of service attacks against PayPal (and others) in 2010. Weatherhead's cohorts, Peter Gibson, Jake Bichall and Ashley Rhodes, were also accused of and plead guilty to participating in "Operation: Payback" -- a 10-day DDoS attack which crippled PayPal (and others) for several hours. PayPal claims the stunt cost it a whopping £3.5 million, or about $5.6 million, in damages.
