“A team of European law-enforcement officials was hot on the trail of a potential terror plot in October, fearing an attack during Christmas season, when their keyhole into a suspect’s phone went dark,” reports the Wall Street Journal:

WhatsApp, Facebook Inc.’s popular messaging tool, had just notified about 1,400 users — among them the suspected terrorist — that their phones had been hacked by an “advanced cyber actor.”

An elite surveillance team was using spyware from NSO Group, an Israeli company, to track the suspect, according to a law-enforcement official overseeing the investigation. A judge in the Western European country had authorized investigators to deploy all means available to get into the suspect’s phone, for which the team used its government’s existing contract with NSO. The country’s use of NSO’s spyware wasn’t known to Facebook… WhatsApp’s Oct. 29 message to users warned journalists, activists and government officials that their phones had been compromised, Facebook said. But it also had the unintended consequence of potentially jeopardizing multiple national-security investigations in Western Europe about which Facebook hadn’t been alerted — and about which government agencies can’t formally complain, given their secret nature…

NSO has faced criticism for selling its products to government agencies in the Middle East, Mexico and India, which Facebook and human-rights research group Citizen Lab, among others, allege used them to spy on dissidents, religious leaders, journalists and political opponents. Among the 1,400 WhatsApp users notified in October, more than 100 fell into these categories, Citizen Lab said. The group, which is based at the University of Toronto’s Munk School of Global Affairs and Public Policy, worked with Facebook on identifying these people… Citizen Lab has issued reports for several years linking NSO’s spyware to governments with a history of human-rights abuses, and said that record should put NSO out of the running for government contracts from Western agencies, said Ronald Deibert, Citizen Lab’s director. “What we have been trying to do with our research is to raise alarm bells….”

On the day WhatsApp sent its alert, the official overseeing the terror investigation in Western Europe said, he was stuck in traffic on his way to work when a call came in from Israel. “Have you seen the news? We’ve got a problem,” he said he was told. WhatsApp was notifying suspects whom his team was tracking that their phones had been hacked. “No, that can’t be right. Why would they do that?” the official said he asked his contact, thinking it a joke. The most immediate concern was a suspected terrorist investigators linked to Islamic State. They had received a tip he was part of a group plotting an attack around Christmas. Once they saw the suspect’s phone receive WhatsApp’s alert, the phone went dark, the official said. The sleuths soon lost access to the suspect’s messages, the official said, indicating he had discarded or disabled the phone. “We only had that one phone,” the official said.

Though that suspect was still under traditional surveillance, “He’s not the only …read more
