The vulnerabilities include two kernel flaws and one in WebKit and Apple released iOS 9.3.5 to fix them. The attack that set off the investigation into the vulnerabilities targeted Ahmed Mansoor, an activist living in the UAE. Earlier this month, he received a text message that included a link to what was supposedly new information on human rights abuses. Suspicious, Manor forwarded the link to researchers at the University of Toronto’s Citizen Lab, who recognized what they were looking at.
“On August 10 and 11, 2016, Mansoor received SMS text messages on his iPhone promising “new secrets” about detainees tortured in UAE jails if he clicked on an included link. Instead of clicking, Mansoor sent the messages to Citizen Lab researchers. We recognized the links as belonging to an exploit infrastructure connected to NSO Group, an Israel-based ‘cyber war’ company that sells Pegasus, a government-exclusive “lawful intercept” spyware product,” Citizen Lab said in a new report on the attack and iOS flaws.
