US government data found on HDD in Africa
Red faces at contractor.

The safe disposal of old computer equipment is once again in the headlines after a hard disk drive (HDD) purchased from a market in Ghana was found to contain sensitive documents belonging to US government contractor Northrop Grumman.
The drive had belonged to a Fairfax, Virginia, employee who still works for the company and contained "hundreds and hundreds of documents about government contracts," said Peter Klein, an associate professor with the University of British Columbia, who led the investigation for the Public Broadcasting Service show Frontline.
Klein would not disclose details of the documents, but he said that they were marked "competitive sensitive" and covered company contracts with the Defense Intelligence Agency, the National Aeronautics and Space Administration and the Transportation Security Agency.
The data was unencrypted, Klein said in an interview. The cost? $40 (£24.60).
Northrop Grumman is not sure how the drive ended up in a Ghana market, but apparently the company had hired an outside vendor to dispose of the PC. "Based on the documents we were shown, we believe this hard drive may have been stolen after one of our asset-disposal vendors took possession of the unit," the Northrop Grumman said in a statement. "Despite sophisticated safeguards, no company can inoculate itself completely against crime."
A Northrop Grumman spokesman would not say who was responsible for disposing of the drive, but in its statement the company noted that "the fact that this information is outside our control is disconcerting."
Some of the documents talked about how to recruit airport screeners and several of them even covered data security practices, Klein said. "It was a wonderful, ironic twist," Klein said. "Here were these contracts being awarded based on their ability to keep the data safe."
According to Klein, it's common for old computers and electronic devices to be improperly dumped in developing countries such as Ghana and China, where locals scavenge the material for components, often under horrific working conditions.
Last year the US Government Accountability Office found that a substantial amount of the country's e-waste ended up in developing countries, where it was often dangerously disposed of.
The reporters bought seven hard drives, Klein said. The other drives contained sensitive information about their previous owners, including credit-card numbers, resumes and online account information.
Off-camera, sources in Ghana told the reporters that data thieves routinely scour these hard drives for sensitive information, Klein said.
Although that may be worrying to some, security experts say that there is already a vast quantity of this type of information available online from criminals who have stolen it from hacked computers.
Compared to hacking, stealing data from old hard drives is pretty inefficient, said Scott Moulton, an Atlanta data-recovery expert who teaches classes on data recovery. "It's a tremendous amount of work, so it's only going to be the bottom-of-the-barrel guys who would do that," he said. "It's happening on a small scale."
