A hacker working for the Sinaloa Cartel in Mexico was able to obtain an FBI official’s phone record information in 2018 and used Mexico City’s surveillance camera system to track and kill informants and witnesses, the Justice Department said in a report. 

The 2018 incident was disclosed in the Justice Department Inspector General’s audit of the FBI’s efforts to “Mitigate the Effects of Ubiquitous Technical Surveillance.”

The report said the FBI was working on the case of Joaquin “El Chapo” Guzman, the former leader of the infamous cartel who was extradited to the United States in 2017, when someone tipped the FBI that the drug-trafficking organization hired a hacker “who offered a menu of services related to exploiting mobile phones and other electronic devices.”

The hacker was able to identify an FBI assistant legal attaché (ALAT) at the U.S. Embassy in Mexico City and was able to use the attaché’s phone number “to obtain calls made and received, as well as geolocation data.”

“According to the FBI, in addition to compromising the ALAT’s phone, the hacker also accessed Mexico City’s camera system, used the cameras to follow the ALAT through the city, and identified people the ALAT met with,” the report states. “According to the case agent, the cartel used that information to intimidate and/or kill potential sources or cooperating witnesses.”

The hacker and victims were not identified in the report. Fox News Digital has reached out to the U.S. Embassy in Mexico City, the State Department, the FBI and Justice Department. 

The report noted that advances in technology have “made it easier than ever for less-sophisticated nations and criminal enterprises to identify and exploit vulnerabilities” created by UTS, a term used to describe the widespread collection and storage od data and analysis often from everyday technologies like smartphones, computers and even vehicles.
