Jail for student who hacked into Facebook from bedroom A student who hacked into Facebook in the "most extensive and grave" case of social media hacking to come before a British court was jailed for eight months yesterday. Glenn Mangham, 26, admitted infiltrating the website from his bedroom in his parents' house between April and May last year. His actions were said to have risked destroying "the whole enterprise" and sparked fears among American authorities of industrial espionage. Mangham, a software development student from Cornlands Road, York, had previously shown the search engine Yahoo how it could improve its security and said he wanted to do the same for Facebook. But prosecutor Sandip Patel rejected his claims, saying: "He acted with determination, undoubted ingenuity and it was sophisticated." Facebook spent $200,000 (£126,400) dealing with Mangham's crime, which triggered a "concerted, time-consuming and costly investigation" by the FBI and British law enforcement. "The prosecution does not accept that the defendant's actions were anything other than malicious," Mr Patel said. Passing sentence, Judge Alistair McCreath told Mangham his actions could have been "utterly disastrous" for Facebook.
