Defense teams across the U.K. are arguing that chat messages obtained by law enforcement malware should not be used as evidence in court.
A document obtained by Motherboard provides more detail on the malware law enforcement deployed against Encrochat devices.
Criminals use so-called Russian, encrypted, or white SIMs to change their phone number, add voice manipulation to their calls, and try to stay ahead of law enforcement.
A document included in the BlueLeaks hack says "senior Sinaloa leaders were using a highly sophisticated encrypted communications platform, Encrochat."
Encrochat's customers include hitmen and drug gangs across Europe.
Messages allegedly sent to Encrochat users warned of a law enforcement takeover. Europol said it won’t comment on "ongoing operations."
