WhatsApp is encouraging its users to upgrade the app to plug a security breach that allowed sophisticated attackers to sneak spyware into phones, in the latest trouble for its parent Facebook.
The vulnerability, first reported by the Financial Times FT, and fixed in the latest WhatsApp update allowed hackers to insert malicious software on phones by calling the target using the app, which is used by 1.5 billion people around the world.
The FT cited a spyware dealer as saying the tool was developed by a shadowy Israel-based firm called the NSO Group, which has been accused of helping governments from the Middle East to Mexico snoop on activists and journalists.
And according to The New York Times, security researchers said the malicious code bore similarities to other tech developed by the firm.
The latest exploit which impacts Android devices and Apple’s iPhones, among others was discovered earlier this month and WhatsApp scrambled to fix it, rolling out an update in less than 10 days.
The firm did not comment on the number of users affected or who targeted them, and said it had reported the matter to US authorities.
