The Government Accountability Office (GAO) confirmed in a report released on Thursday that sensitive defense-related items are available for sale on eBay and Craigslist, many of which were stolen from the U.S. Military. The investigators also identified U.S. government property also stolen and put on sale.

Undercover investigators managed to purchase items of sensitive-military nature, such as an F-14 antenna and enhanced Small Arms Protective Inserts on eBay or nuclear biological chemical gear on Craigslist.

If the items had been purchased by members of the general public, GAO investigators said, there is a high risks that they could have been further resold overseas, which is illegal, as the items are currently on the U.S. Munitions List (which means there are restrictions to oversea sales).

“Unauthorized individuals, companies, organization and other countries continue their attempts to obtain sensitive items related to the defense of the United States,” which would pose a threat to national security, the Subcommittee on National Security and Foreign Affairs said in the report.

Not all buyers on websites that commercialize sensitive items pose a threat to national security, as many of them are hobbyists, military enthusiasts and emergency response or law enforcement units; however, there is a “real risk that illegal weapons, brokers, terrorists, and unauthorized agents of foreign governments also number among the potential buyers,” the report says.

During its undercover investigation, GAO worked with eBay’s Fraud Investigations Team to obtain information on the identity and account history of the sellers, and scanned the DOD Employee Interactive Data System to establish whether they were active members of the U.S. military.

The investigation conducted from January 2007 through March 2008 identified numerous defense-related objects for sale on eBay and Craigslist, which were easily available to buyers “no questions asked,” the investigators said.

Among items available for purchase, investigators bought two F-14 components from two separate buyers (which, according to the report, are highly demanded in Iran), night vision goggles with image intensifier tube, an Army Combat Uniform (ACU) and accessories, or body armor vests and Small Arms Protective Inserts (SAPI).
