GAO found numerous defense-related items for sale to the highest bidder on eBay and Craigslist. A review of policies and procedures for these Web sites determined that there are few safeguards to prevent the sale of sensitive and stolen defense-related items using the sites. During the period of investigation, GAO undercover investigators purchased a dozen sensitive items on eBay and Craigslist to demonstrate how easy it was to obtain them. Many of these items were stolen from the U.S. military. According to the Department of Defense (DOD), it considers the sensitive items GAO purchased to be on the U.S. Munitions List, meaning that there are restrictions on their overseas sales. However, if investigators had been members of the general public, there is a risk that they could have illegally resold these items to an international broker or transferred them overseas.
