Here's how to update WhatsApp to the latest version after hack sparks security warning

WhatsApp was targeted by an “advanced cyber actor” which exploited a major vulnerability in the messaging app to install spyware.

The company said a “a select number of users” had been chosen by an “advanced cyber actor” in a breach uncovered earlier this month.

The spyware gave hackers the ability to take over the functions of mobile phone operating systems remotely.

WhatsApp said the vulnerability has been fixed, but is urging users to update the app to its most recent version to provide the highest level of security.

Here's how to update your app

A WhatsApp spokesperson said the company was encouraging people to upgrade to the latest version of the app and keep their mobile operating system up to date.

This helps protect against potential targeted exploits designed to compromise information stored on mobile devices.

“We are constantly working alongside industry partners to provide the latest security enhancements to help protect our users,” they added.
