WhatsApp pressed users to update its messaging service, following a report that a vulnerability in the software allowed attackers to hack into people’s phones using commercial spyware.

WhatsApp said it had discovered a vulnerability in early May that could enable attackers to insert and execute code on mobile devices. This made changes to its infrastructure late last week to block the attacks from taking place, adding that only a select number of users appeared to have been targeted through the vulnerability by an advanced cyber actor.

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,” a spokeswoman for the company said Tuesday.
