HERE'S THE COMPANY THAT DESIGNED THE ESPION SOFTWARE DISCOVERED IN THE INSTATS WHATSAPP MESSENGER.

WhatsApp's instant messaging platform teams have recently discovered a major loophole for spying on a phone through a single call, the Financial Times reported on Monday.

Spyware, created by an "advanced technology actor", used a flaw in the instant messaging application WhatsApp to take control of mobile phones, says the Financial Times. A patch removing the breach was deployed on Monday 13 May.

According to the British media, this flaw was exploited by Pegasus software, conceived by the Israeli company NSO Group, one of the most advanced companies in the development of surveillance software.

According to a spokesman for Facebook, this flaw allowed anyone to spy on all the activity of a mobile phone, by a simple call. Even if the victim did not take the time to answer them. The company did not reveal how many smartphones were infected among the 1,5 billion users.

"There is nothing that a user could have done"

John Scott-Railton, a researcher at the Citizen Lab, a cybersecurity reference research group, described the hacking as "very scary". "There is nothing that a user could have done, unless they did not have the application," he said.
