"Roy Zoppoth stands over a Xerox 914 copy machine, the world's first, which was used in soviet embassies all over the world. The machine was so complex that the CIA used a tiny camera designed by Zoppoth to capture documents copied on the machine by the soviets and retrieved them using a "Xerox repairman" right under the eyes of soviet security."
“From the numbers of cameras ordered, we later realized the CIA had placed secret cameras in every Xerox copy machine in all embassies in the world – friend and foe alike.”
Another - Russian security agencies use Western hardware ( i mean what other option do they have seriously ?). Before being put to use the hardware is disassembled as much as it is possible with specific goal of finding the "mini-scanners". Similar history - http://www.spybusters.com/Great_Seal_Bug.html
