Software development Student from York, Glenn Mangham admitted hacking into the Facebook between April and May of this year, but argued that he only wanted to show Facebook how to improve its security as he had done for Yahoo(Mangham, who had previously been rewarded by Yahoo for finding vulnerabilities in its systems).
Facebook discovered evidence that pointed back to Mangham and he was arrested by the Metropolitan Police Central e-Crime Unit (PCeU) in June.
He hacked into Facebook systems and downloaded “highly sensitive intellectual property”, said prosecutor Sandip Patel.
Mangham's defence has argued that he was an "Ethical Hacker", he was attempting to discover the vulnerabilities so that Facebook can fix it.
"That was his plan here but the activity was found by accident," said barrister Tom Ventham.
Facebook said its users’ personal data was not compromised in the security breach. Mangham will be sentenced on 17 February 2012.
