Efraim Diveroli (born December 20, 1985) is an American former arms dealer and author. His company, AEY Inc., was a major weapons contractor for the U.S. Department of Defense. The U.S. government suspended AEY for violating its contract after AEY provided Chinese ammunition and attempted to hide the origins by repackaging it as being from Hungary, thus violating the American arms embargo against China. As a result of the publicity surrounding the contract and the age of the arms dealers – Diveroli was 21 and partner David Packouz was 25 when AEY landed the ammunition deal – the United States Army began a review of its contracting procedures.Diveroli was sentenced to four years in federal prison. He is a central subject of the Todd Phillips dramedy film War Dogs, released in 2016, as well as a memoir written in conjunction with convicted fraudster Matthew Cox and published in 2016.
