A federal report says in 2018 the Sinaloa Cartel hired a hacker to track an FBI agent to find informants and witnesses against the cartel boss.

In 2018, a hacker hired by the Mexican Sinaloa drug cartel run by the infamous kingpin Joaquín “El Chapo” Guzmán spied on the U.S. Embassy in Mexico City with the goal of identifying “people of interest” for the cartel to target and kill, according to a new U.S. government watchdog report.

Sinaloa cartel hackers broke into an FBI official's phone, using data to murder informants, the DOJ said. We're hearing from Katarina Szulc, an independent journalist in Mexico, who has reported on cartels for years.
