IPHONE users are being warned to update WhatsApp immediately following a cyber attack.

WhatsApp confirmed it had fixed the security glitch in its iOS and Mac apps on Friday.

The attack targeted dozens of Whatsapp users and was labelled an “advanced spyware campaign” over a three-month duration, according to Donncha Ó Cearbhaill, who heads Amnesty International’s Security Lab, confirmed.

Ó Cearbhaill added that the bug was a “zero-click”, meaning the victim could do nothing to avoid the indiscriminate targeting of their device.

The attacker would then “compromise your device and the data it contains, including messages.”

The culprit is yet to be identified.

Global cyber crime is on the rise with 73 per cent of adults in the US recently reporting they had experienced an online attack.
