South Australian police have arrested 55 individuals in the latest phase of Operation Iron Edge, a major crackdown on organized crime involving $37.9 million in cryptocurrency assets. The arrests, announced on November 3, are part of a collaborative effort between Australia's federal police and the FBI, utilizing the FBI-controlled encrypted app AN0M to infiltrate criminal networks. The operation has resulted in approximately 800 new charges related to drug trafficking, weapons offenses, and conspiracy crimes. This follows a recent High Court ruling allowing intercepted encrypted messages to be used as evidence, bolstering the legal framework for these arrests. Authorities have highlighted the growing sophistication of cryptocurrency-related crimes, as noted by Europol.
