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.

The hacker was able to break into the agent’s phone remotely and watch their incoming and outgoing calls, and even monitor the phone’s geolocation.

A hacker working for Joaquin "El Chapo" Guzmán's Sinaloa drug-trafficking cartel infiltrated FBI communications and city surveillance in Mexico City, helping to identify and silence informants, a newly released federal report reveals.
