According to TheRegister.com, Australian police arrested 55 individuals last week in the latest phase of Operation Ironside, seizing assets worth AUD$25.8 million ($17 million) following a High Court ruling that validated evidence gathered through the backdoored AN0M messaging app. The operation began in 2018 after US authorities shut down Phantom Secure, with the FBI and Australian Federal Police creating AN0M as a replacement service that included hidden backdoor access to criminal communications. The recent raids on 23 properties in South Australia represent the “third tranche” of activity connected to AN0M, which the High Court deemed legal in early October because it constituted a closed system rather than telecommunications network. This legal validation clears the path for continued use of evidence gathered through the controversial operation.

The Closed System Doctrine Creates New Legal Framework
The High Court’s ruling establishes a critical distinction between traditional telecommunications networks and purpose-built communication systems that could have far-reaching implications for digital privacy law. By classifying AN0M as a “closed system,” the court essentially created a legal loophole that allows law enforcement to bypass traditional wiretapping restrictions. This precedent could encourage other governments to develop similar controlled environments specifically designed to attract criminal users while maintaining lawful access. The decision effectively says that if law enforcement creates the entire communication ecosystem, they’re not intercepting communications but rather monitoring their own system.
The Escalating Encryption Arms Race
This case represents the latest escalation in the long-running battle between law enforcement and encryption technologies. The AFP’s call for “accountable encryption” last year signals where this conflict is heading – toward mandated backdoors in commercial encryption products. What’s particularly concerning is that AN0M produced more evidence than authorities could handle, demonstrating both the effectiveness and potential overreach of such surveillance operations. As criminals migrate to new platforms following each takedown, we’re likely to see more government-operated honeypots designed to replace the services they disrupt. The success of AN0M suggests this tactic will become a standard tool in law enforcement’s digital arsenal.
International Law Enforcement Collaboration Model
The FBI-AFP partnership on AN0M establishes a blueprint for multinational surveillance operations that could spread rapidly. Other intelligence-sharing alliances like Five Eyes are almost certainly studying this model for adaptation. The technical sophistication required to maintain a convincing encrypted messaging service while secretly monitoring all communications represents a significant investment, but the results demonstrate the payoff can be substantial. We should expect to see similar joint operations emerging, particularly targeting transnational criminal organizations that operate across multiple jurisdictions. The challenge will be ensuring adequate oversight and preventing mission creep as these capabilities expand.
The Slippery Slope of Government-Run Platforms
While targeting criminal communications is a legitimate law enforcement objective, the AN0M case raises troubling questions about where this approach might lead. If governments can create and operate communication platforms with built-in surveillance capabilities for criminal investigations, what prevents them from deploying similar systems more broadly? The legal rationale that these are “closed systems” could potentially be applied to government services, critical infrastructure communications, or even platforms offered to the general public. The lack of appeal options in Australia’s judicial system means this precedent stands without immediate challenge, potentially influencing similar cases in other common law countries.
Predicting the Next Phase of Digital Surveillance
Looking ahead 12-24 months, we’re likely to see three key developments. First, criminal organizations will become more sophisticated in vetting communication platforms, potentially developing their own custom solutions rather than relying on third-party services. Second, legitimate encrypted messaging services will face increased pressure to implement “accountable encryption” features that provide law enforcement access under specific circumstances. Third, we should expect more legal challenges to similar operations in other jurisdictions, testing whether other court systems will adopt Australia’s “closed system” reasoning. The fundamental tension between privacy and security continues to evolve, with AN0M representing a significant shift toward more aggressive law enforcement tactics in the digital realm.
