Facebook has deleted the accounts of employees who work at the Israeli NSO group only one after it sued it over WhatsApp hack. "Your account has been deleted for not following our terms," said a message sent to one employee by Facebook-owned Instagram. "You won't be able to log into this account, and no one else will be able to see it. We're unable to restore accounts that are deleted for these types of violations." Last Tuesday, WhatsApp sued the Israeli spyware maker for mass exploiting a critical vulnerability that targeted 1,400 devices with spyware. They targeted journalists, diplomats, human rights activists, senior government officials and other parties. Deceased Saudi journalist, Jamal Khashogji, was among those whose devices were hacked. The lawsuit seeks, among other things, a permanent injunction barring all NSO employees from "accessing or attempting to access WhatsApp's or Facebook's services, platform, and computer systems."
