International Cyber Digest on X: "The CIA and West German intelligence secretly bought Swiss encryption maker Crypto AG in 1970, turning the machines governments paid to protect their secrets into a way to read them. Those governments had no idea the machines were rigged to read their messages. In the 1980s, Crypto devices accounted for roughly 40% of the foreign government messages the NSA decoded. The CIA didn't sell the company until 2018 and called the operation "the intelligence coup of the century.""
