Microsoft has become the latest technology giant to respond to WikiLeaks’ release of 8,761 documents allegedly detailing the CIA’s spying methods.

The files forming the enormous Vault 7 release claim that the agency was able to exploit zero-day vulnerabilities in Windows, which it used to secretly monitor users.

Microsoft has encouraged customers to update to the latest version of its desktop operating system, saying that most of the vulnerabilities allegedly used by the CIA have already been patched.

“Most of the issues are dated and likely have been addressed in its latest software,” a Microsoft spokesperson told The Wall Street Journal.

Older versions of Windows, however, could still be at risk.

Microsoft’s statement echoes previous responses made by Apple and Google, who were forced into action by WikiLeaks’ claim that the CIA also took advantage of unknown flaws in iOS and Android.

Both firms urged customers to update to the latest software, as doing so as gives them the highest level of protection possible. They are currently working to fix any outstanding issues.

Julian Assange, meanwhile, has offered to give technology companies exclusive access to redacted documents detailing all of the CIA’s cyber weapons, in order to help them to prepare themselves against hackers.
