The Department of Defense (DOD) acquisition chief confirmed on Friday in a press conference that they've been silently working on a "Do Not Buy" list of companies known to use Chinese and Russian software in their products.

Ellen Lord, defense undersecretary for acquisition and sustainment, said the Pentagon started compiling the list about six months ago. She said the Department shared the list with DOD agencies but have not enforced or made it obligatory.
