A hacking group called d33ds broke into the online shop of a rival hacker who sells unauthorized access to high-profile websites and data.

This illegal marketplace has been used in the past to advertise information stolen from websites belonging to the U.S. Army, the U.S. Department of Defense, the South Carolina National Guard and other institutions. Its owner, a hacker calling himself Srblche, also offered services that included compromising the particular servers his customers wanted.

According to Rob Rachwald, director of security strategy at security firm Imperva, Srblche is believed to be Kuwaiti. "We tracked his Facebook profile," Rachwald said Thursday.
