A federal magistrate is granting Sony the right to acquire the internet IP addresses of anybody who has visited PlayStation 3 hacker George Hotz’s website from January of 2009 to the present.

Thursday’s decision by Magistrate Joseph Spero to allow Sony to subpoena Hotz’s web provider (.pdf) raises a host of web-privacy concerns.

Respected for his iPhone hacks and now the PlayStation 3 jailbreak, Hotz is accused of breaching the Digital Millennium Copyright Act and other laws after he published an encryption key and software tools on his website that allow Playstation owners to gain complete control of their consoles from the firmware on up.

Sony also won subpoenas (.pdf) for data from YouTube and Google, as part of its lawsuit against the 21-year-old New Jersey hacker, as well as Twitter account data linked to Hotz, who goes by the handle GeoHot.

Bluehost maintains Hotz’s geohot.com site. The approved subpoena requires the company to turn over “documents reproducing all server logs, IP address logs, account information, account access records and application or registration forms” tied to Hotz’s hosting. The Bluehost subpoena also demands “any other identifying information corresponding to persons or computers who have accessed or downloaded files hosted using your service and associated” with the www.geohot.com website, including but not limited to the “geohot.com/jailbreak.zip file.”
