PSA Update your WhatsApp NOW.
Facebook-owned WhatsApp warned users to upgrade the application to plug a security hole that allowed for the injection of very sophisticated malware that could be used to spy on journalists, activists, and others.
WhatsApp said it released an update to fix the latest vulnerability in the messaging app used by 1.5 billion people around the world.
WhatsApp encourages people to upgrade to the latest version of our app, as well as keep their mobile operating system up to date, to protect against potential targeted exploits designed to compromise information stored on mobile devices. Security researchers have found that Android and Apple phones can be infected with the spyware with a simple audio call through WhatsApp, even if the user does not answer and its encryption feature has encouraged activists, journalists, and others for sensitive information.
Facebook did not comment on the number of users affected or who targeted them and said it had reported the matter to US authorities.
