NSO Group – the controversial Israeli cyber-firm making some of the world’s most sophisticated spyware – has been accused of a new hack using WhatsApp. The popular messaging app, a Facebook subsidiary with some 1.5 billion users, discovered in early May that “an advanced cyber actor” had infected an unknown number of smart phones by exploiting a vulnerability in its voice calling feature, according to the Financial Times. Even if the target didn’t pick up the call, the malware was able to infect the phone and expose the user’s personal information. WhatsApphas urged all users to update their operating systems and has involved human rights organizations and law enforcement in the investigation.
NSO Group has denied any involvement in the WhatsApp hack. The cyber-surveillance company leases its highly sophisticated malware to intelligence agencies
