Facebook shared a security advisory on Monday, May 13th warning WhatsApp users that an “advanced cyber actor” has been spreading spyware through the app by taking advantage of a buffer overflow vulnerability. All that it took to install the spyware on a target’s phone was calling them through the WhatsApp mobile app.
According to the UK’s National Cyber Security Centre, WhatsApp has announced that a small number of users have been affected and that everyone who uses the app should update it from their respective app stores as soon as they can. More
The spyware has been credited to an Israel company, NSO Group that specializes in engineering hackware for intelligence agencies. “NSO Group sells its software to governments around the world, in particular in the Middle East, a business that has given it a market valuation of around $1bn (£770m). This single bug alone will have meant millions of pounds in revenue.” More
