Operation Trojan Shield
Ironside · Greenlight · 8 June 2021 - under construction

Operation Trojan Shield (USA), also known as Operation Task Force Greenlight (Europe) and Operation Ironside (AU/NZ), was a joint covert operation of the law enforcement agencies of 16 countries, in which serious organised crime was attacked in an unprecedented way. By supplying criminals with tampered smartphones, in combination with the FBI-controlled ANOM network and cutting-edge software developed by the Australian AFP, the police was able to read the trusted communication of 12,000 smartphones of more than 300 criminal organisations worldwide [5].

The operation was launched in 2018 and was led by the American FBI. Rather than hacking into an existing messaging service – like it was done with Phantom Secure and EncroChat – the FBI took control of small company called 'ANOM', and turned it into a worldwide operating honeypot.

After the Canadian secure telephone service Phantom Secure had been taken down by the FBI [6], it was anticipated that the criminal world would soon be looking for alternative solutions. It is then that they decided to take over ANOM. The interest in ANOM was initially small, starting with just 50 devices in an Australian beta test in October 2018, but the police soon discovered that all devices were used for criminal activities. The penetration of ANOM devices increased in mid-2019, and accelerated further after the European Police first took down EncroChat in June 2020 and then Sky ECC in March 2021 [7][8]. By May 2021, approx. 11,880 ANOM devices had been released, 9000 of which were actively being used. The sting operation culminated in a large number of location searches executed simultaneously around the globe on 7 and 8 June 2021.

In the operation, the FBI worked closely together with the Australian AFP and, from October 2019, with the police organisations of 14 EUROPOL countries, led by the Netherlands and Sweden. In total, the police intercepted more than 27 million encrypted messages, enough for several years worth of investigations. The operation was revealed to the public in press conferences on 8 June 2021 [1]. It was also revealed that the ANOM software had been developed by the Australian Federal Police (AFP), and that the Dutch National Police (KLPD) had developed special software tools for the identification of suspects and for filtering and analysis of the vast amount of data.
