The comittee of the German Bundestag tasked with investigating NSA spying activities is apparently considering switching to mechanical typewriters. At least that is what the head of the enquiry board Patrick Sensburg (CDU) told German public broadcaster ARD.
The whole thing probably isn’t a good idea, as an NSA document from 2007 shows. It describes the GUNMAN Project in the ’80s where NSA scrutinised typewriters from their Moscow embassy and found the Russians had cleverly bugged them with an integrated curcuit built right into the typewriter. The Russians used this bug as early as 1976 and it went undiscovered for years.
