Whatsapp spyware

WhatsApp disclosed a major security vulnerability that allowed hackers to remotely install spyware on mobile devices.

The vulnerability, discovered earlier this month, allowed third parties to see and intercept encrypted communications. The spyware deployed has been traced back to NSO Group, an Israeli cyber company alleged to have enabled Middle East governments to surveil its citizens.

“The attack has 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,” WhatsApp announced in a statement.

NSO Group has denied involvement.

“Under no circumstances would NSO be involved in the operating or identifying of targets of its technology, which is solely operated by intelligence and law enforcement agencies,” the company said in a press release.

WhatsApp, which is owned by Facebook, has released a patch to fix the vulnerability and urges all users to update as soon as possible.

“Given the limited information we collect, it is hard for us to say with certainty the impact to specific users,” WhatsApp said in a statement. “Out of an abundance of caution we are encouraging all users to update WhatsApp as well as keep their mobile OS up to date.”
