A notorious piece of spyware has been used to target the wife of a slain Mexican journalist, security researchers said Wednesday, adding to ongoing public scrutiny of the company that developed the powerful surveillance tool.

Days after Javier Valdez Cárdenas, a reporter known for his coverage of international drug trafficking, was murdered in May 2017, multiple attempts were made to hack the phone of his widow, Griselda Triana, with spyware made by NSO Group, according to Citizen Lab, a digital rights and research organization at the University of Toronto.

The text messages sent to Triana, who is also a journalist, were laced with software that would have turned her phone into a multifaceted surveillance device, Citizen Lab researchers said. One of the messages tugged at her grief as a widow, asking, “What do you think of this story?”

Triana didn’t click on either link and turned the texts over to Mexican advocacy groups, which shared them with Citizen Lab for forensic analysis.

The surveillance tool aimed at Triana is known as Pegasus, the researchers said, an invasive malware strain developed by Israeli vendor NSO Group. The spyware uses a chain of exploits capable of accessing a target device’s microphone and camera, contact list, GPS location, and personal passwords.

Last November, Citizen Lab published evidence that two of Valdez’s colleagues received Pegasus-laden texts claiming to have evidence linking the Valdez’s slaying to a cartel.

The researchers said a Mexican government-linked organization was behind those attempted hacks. The links sent to Triana would have directed her to domains controlled by the same organization, Citizen Lab said. Researchers have not specifically identified that organization, referring to it only as RECKLESS-1.

There are now 11 documented cases of Pegasus being trained on journalists in Mexico and elsewhere, according to Citizen Lab. The spyware was allegedly used to track Saudi journalist Jamal Khashoggi before his brutal murder, according to a lawsuit filed against NSO Group by a Saudi dissident in December.

NSO Group co-founder Shalev Hulio has denied that the company’s technology was used to track Khashoggi.

NSO Group says it carefully vets customers and that governments use its products to fight crime and terrorism. But in addition to journalists, Pegasus has been used to target anticorruption watchdogs and political dissidents, according to Amnesty International and Citizen Lab. In Mexico alone, Citizen Lab has documented 25 people – including lawyers, politicians, and public health professionals – who have been targeted by Pegasus.

An NSO Group spokesperson told CyberScoop that any use of the company’s tools that “falls outside of preventing or investigating crime and terror is considered a misuse and will be investigated. The company takes misuse seriously and has the right to shut down the system if necessary.”

NSO Group is one of multiple spyware vendors whose specialized surveillance services have been in demand from governments. The company, whose founders recently re-acquired it from a private equity firm, reported $250 million in revenue and dozens of customers last year.
