A co-founder of file-sharing website Pirate Bay was sentenced to two years in jail on Thursday for hacking into computers at a company that manages data for Swedish authorities and making illegal online money transfers, a court said. Gottfrid Svartholm Warg was extradited to Sweden last year from Cambodia to begin a one-year jail sentence after being convicted in 2009 of internet piracy. He was then charged by authorities as part of the separate hacking investigation. "The hacking has been very extensive and technically advanced," the Nacka district court said in a statement. "The attacker has affected very sensitive systems." He had denied the charges. Prosecution documents say Warg, a 28-year-old Swede, managed to transfer 24,200 Danish crowns ($4,300) online, but also attempted, in several different transactions, to transfer a total of around 683,000 euros ($915,500). The investigation was into data infringement involving outsourcing firm Logica. Swedis
