Hackers are taking credit for at least three breaches at anti-piracy firm MediaDefender. The newly revealed attacks threaten to turn what started as an embarrassing e-mail leak into a full-blown security meltdown for the company. The revelations began Saturday, when more than 6,000 internal company e-mails were exposed in a 700-megabyte BitTorrent download. A note from the hackers that accompanied the download points to a MediaDefender employee’s personal Gmail account as the source of the purloined mail, which covered six months of internal correspondence.
