Currently serving a 10-year prison sentence, Jeremy Hammond is the hacker who stole 60,000 credit card numbers and used them to make donations to charity. So quite a nice hacker then? He certainly seems to be broadly on the side of good, attacking neo-nazis and holocaust deniers, but there’s no denying he’s on the wrong side of the law at the same time. One of his biggest achievements was hacking the e-mails of the Stratfor group, who specialize in global intelligence, and publishing 973 of them on the WikiLeaks website. Among the revelations contained in the e-mails were details of Osama bin Laden’s death and plans to incite a revolution in Venezuela. It was shocking stuff, but it was the credit card theft that saw him sent to jail, some say unfairly.
