WhatsApp discovers 'targeted' surveillance attack
Hackers were able to remotely install surveillance software on phones and other devices using a major vulnerability in messaging app WhatsApp, it has been confirmed.
WhatsApp, which is owned by Facebook, said the attack targeted a "select number" of users and was orchestrated by "an advanced cyber-actor".
A fix was rolled out on Friday.
On Monday, WhatsApp urged all of its 1.5 billion users to update their apps as an added precaution.
