In March 2017, WikiLeaks has published more than 8,000 documents on the CIA. The confidential documents, codenamed Vault 7, dated from 2013–2016, included details on the CIA's software capabilities, such as the ability to compromise cars, smart TVs,[82] web browsers (including Google Chrome, Microsoft Edge, Firefox, and Opera),[83][84] and the operating systems of most smartphones (including Apple's iOS and Google's Android), as well as other operating systems such as Microsoft Windows, macOS, and Linux.[85] WikiLeaks did not name the source, but said that the files had "circulated among former U.S. government hackers and contractors in an unauthorized manner, one of whom has provided WikiLeaks with portions of the archive."[82]
