As part of an international investigation, police said this week they had infiltrated and taken down an encrypted chat app called Ghost used by criminals across the world.

In March 2021, police in Belgium and the Netherlands raided more than 200 homes and arrested dozens of suspected criminals after cracking into Sky ECC, an encrypted chat app based in Canada and the U.S. that claims to offer “the world’s most secure messaging platform.”

Australian police said Wednesday they have infiltrated Ghost, an encrypted global communications app developed for criminals, leading to dozens of arrests.

An international law enforcement operation has dismantled encrypted communication platform, Ghost, notorious for enabling large-scale drug trafficking and money laundering, marking a significant blow to global organized crime networks.
