Australian police have arrested 38 suspects in raids across four states, as well as making arrests in Canada, Sweden, Ireland, and Italy, after infiltrating the encrypted global communications app Ghost. The app's alleged administrator, Jay Je Yoon Jung, appeared in court on charges related to supporting a criminal organization. Australian police claim that hundreds of criminals, including organized crime members, have used Ghost to import drugs and order killings. The app was developed specifically for criminal use in 2017, and Australian police were able to decrypt the communications with the help of technical resources provided by French officers.
