Cybersecurity experts have warned WhatsApp users to update the messaging app as soon as possible following the discovery of a major vulnerability that could allow attackers to install a malicious code on smartphones.
The Facebook-owned app said it identified and fixed the issue earlier this month but Citizen Lab, a research group at the University of Toronto, suspects that an attacker attempted to exploit it again on Sunday.
WhatsApp believes that a select number of users were targeted by an advanced cyber actor, exploiting its voice calling feature, which it said had all the hallmarks of a private company reportedly that works with governments to deliver spyware that takes over the functions of mobile phone operating systems.
