WhatsApp has confirmed it has been targeted by hackers with surveillance software they say resembles a spyware developed by intelligence agencies.
WhatsApp has described the attack as targeted at a “select number” of users, and said it was carried out by “an advanced cyber actor”.
A fix for the vulnerability was rolled-out last Friday, and the company is urging its 1.5 billion users to update their apps as a precaution.
The software worked by using the app’s call function to ring a target’s device. Even if the call was not answered, the software would be installed and the record of the call would vanish from the device’s call log.
