Freak is a vulnerability caused by software engineers making encryption weaker in operating systems as a result of an order by the USA in the 1990s.
Previously, it was known that the Freak vulnerability affected devices such as Apple and Android operating systems.
Microsoft described Freak “as an industry wide issue that is not specific to Windows operating systems”.
Microsoft doesn’t believe that peoples’ computers have yet been publicly exploited.
Microsoft said it is working with its partners to give information to customers to help them secure their machines. The security advisory can be found here.
