Bugged typewriters
26 October 2015

During the 1970s and 80s, the IBM Selectric was a popular typewriter with a unique replaceable print ball that provided superiour quality. It was widely used at the US Embassies around the world for typing classified documents.

Unknown to the Americans however, the Soviets managed to plant bugs inside these typewriters, which remained undiscovered for eight years. Crypto Museum now explains how the bug worked and how they were eventually found.

We need your help
28 September 2015

A few years ago, Crypto Museum aquired the spy radio set shown in the image on the right. It is listed in the Louis Meulstee's book Wireless for the Warrior, Volume 4, as the French 1950s Minature, but we now have reason to believe that it is not French but rather East-European. Please help us identifying this radio set.

Enigma Corrosion Alert
16 February 2015

Researchers at EnigmaMuseum.com in the US have discovered that some WWII-era Enigma machines can be seriously damaged by a certain type of light-green lamp filter.
