$1 phone scanner finds seven Pegasus spyware infections

Seven out of 2,500 scans may sound like a small group, especially in the somewhat self-selecting customer base of iVerify users, whether paying or free, who want to be monitoring their mobile device security at all, much less checking specifically for spyware. But the fact that the tool has already found a handful of infections at all speaks to how widely the use of spyware has proliferated around the world. Having an easy tool for diagnosing spyware compromises may well expand the picture of just how often such malware is being used.

“NSO Group sells its products exclusively to vetted US & Israel-allied intelligence and law enforcement agencies,” NSO Group spokesperson Gil Lainer told WIRED in a statement. “Our customers use these technologies daily.”

iVerify vice president of research Matthias Frielingsdorf will present the group’s Pegasus findings at the Objective by the Sea security conference in Maui, Hawaii, on Friday. He says that it took significant investment to develop the detection tool because mobile operating systems like Android, and particularly iOS, are more locked down than traditional desktop operating systems and don’t allow monitoring software to have kernel access at the heart of the system. Cole says that the crucial insight was to use telemetry taken from as close to the kernel as possible to tune machine-learning models for detection. Some spyware, like Pegasus, also has characteristic traits that make it easier to flag. In the seven detections, Mobile Threat Hunting caught Pegasus using diagnostic data, shutdown logs, and crash logs. But the challenge, Cole says, is in refining mobile monitoring tools to reduce false positives.

Developing the detection capability has already been invaluable, though. Cole says that it helped iVerify identify signs of compromise on the smartphone of Gurpatwant Singh Pannun, a lawyer and Sikh political activist who was the target of an alleged foiled assassination attempt by an Indian government employee in New York City. The Mobile Threat Hunting feature also flagged suspected nation-state activity on the mobile devices of two Harris-Walz campaign officials—a senior member of the campaign and an IT department member—during the presidential race.

“The age of assuming that iPhones and Android phones are safe out of the box is over,” Cole says. “The sorts of capabilities to know if your phone has spyware on it were not widespread. There were technical barriers and it was leaving a lot of people behind. Now you have the ability to know if your phone is infected with commercial spyware. And the rate is much higher than the prevailing narrative.”
