Encrypted messaging apps: a persistent challenge in fighting organised crime
Posted By John Coyne and Liam Auliciems on October 28, 2024 @ 10:19
Last month, about 700 Australian Federal Police (AFP) officers executed arrest warrants nationwide under Operation Kraken. This operation targeted Jay Je Yoon Jung, the alleged architect behind Ghost, an encrypted messaging app explicitly designed for organised crime groups.
While Operation Kraken showcased Australia’s ability to disrupt sophisticated criminal networks, it also highlighted a pressing issue: the persistent challenge posed by evolving encryption technologies that organised criminal groups are so quickly adopting, allowing them to outpace law enforcement efforts.
Ghost represented a significant leap in the technological capabilities of organised crime. Allegedly developed by Jung as a business venture, it facilitated a range of illicit activities, from drug and weapons trafficking to money laundering. An estimated 800 devices were in circulation globally, 376 of which in Australia. Disguised as standard smartphones, they allowed users to create anonymous profiles and communicate securely. The breadth of activities coordinated through Ghost reinforces the escalating sophistication of organised crime groups and, just as importantly, their ability to adopt and operationalise new technology.
Ghost was brought to the AFP’s attention by Europol, the European Union’s international policing division. Europol prompted formation of a global task force, with the AFP joining forces with the US Federal Bureau of Investigation and the Royal Canadian Mounted Police. Through technical ingenuity and undercover operations, the AFP accessed Ghost’s software. This replicated the success of previous operations, such as Operation Ironside, which had effectively dismantled another encrypted messaging app, AN0M.
Despite these victories, the operation highlights the broader implications of encrypted messaging apps for law enforcement. While they challenge law enforcement with their encryption, they also raise significant questions regarding privacy and mass surveillance.
Operation Kraken exposes three significant challenges for Australian law enforcement when targeting organised crime groups: disrupting their current use of encrypted technology, accelerating law enforcement adoption of new technologies and preventing criminal exploitation of future advancements.
The success of Operation Kraken hinged on the delicate interplay between human intelligence and technological expertise. The authorities’ initial breakthroughs in identifying and infiltrating Ghost were achieved through human sources in organised crime groups.
But another encrypted messaging app will surely emerge to take its place. So collaboration between human intelligence and cutting-edge technology must remain a cornerstone of law enforcement strategies to stay one step ahead of evolving criminal threats.
Australia’s 2018 encryption laws have enabled law enforcement to compel tech companies to grant access to encrypted communications. However, this has sparked a debate over the potential creation of backdoors that could compromise user privacy and safety. Both the debate and government policy responses must recognise that encryption is essential to modern life and that security is key to tech companies’ commercial success. It’s little wonder that achieving a delicate balance between safeguarding privacy and ensuring public safety remains a contentious issue that requires careful navigation.
The Australian government and law enforcement agencies must prioritise ongoing innovation and international collaboration to stay ahead of criminal use of encrypted messaging. Maintaining operational secrecy while maximising intelligence gains is essential to ensuring that authorities can remain proactive in their fight against organised crime. Investment in training and resources for law enforcement agencies will empower them to combat these evolving technologies.
To ensure sustained success, Australia should consider establishing a dedicated task force focused on proactively assessing encrypted messaging apps and investing in training for a new generation of digital investigators. Engaging in ongoing dialogue with technology firms will be crucial, enabling law enforcement to strike a balance between privacy concerns and the necessity of access to encrypted communications during critical investigations.
As we navigate the complexities of organised crime in the digital age, the insights from Operation Kraken should catalyse Australia’s law enforcement community to embrace innovation, foster cooperation and remain agile in the face of emerging challenges. Only through a multifaceted approach can we ensure the safety and security of our communities while effectively countering the threat posed by organised crime.
