Report: Uncovering the clients of cyberespionage firm Circles

"Running in Circles: Uncovering the Clients of Cyberespionage Firm Circles", 1 December 2020

Circles is a surveillance firm that reportedly exploits weaknesses in the global mobile phone system to snoop on calls, texts, and the location of phones around the globe. Circles is affiliated with NSO Group, which develops the oft-abused Pegasus spyware.

Circles, whose products work without hacking the phone itself, says they sell only to nation-states. According to leaked documents, Circles customers can purchase a system that they connect to their local telecommunications companies’ infrastructure, or can use a separate system called the “Circles Cloud,” which interconnects with telecommunications companies around the world.

... We determine that the governments of the following countries are likely Circles customers: Australia, Belgium, Botswana, Chile, Denmark, Ecuador, El Salvador, Estonia, Equatorial Guinea, Guatemala, Honduras, Indonesia, Israel, Kenya, Malaysia, Mexico, Morocco, Nigeria, Peru, Serbia, Thailand, the United Arab Emirates (UAE), Vietnam, Zambia, and Zimbabwe.

Some of the specific government branches we identify with varying degrees of confidence as being Circles customers have a history of leveraging digital technology for human rights abuses. In a few specific cases, we were able to attribute the deployment to a particular customer, such as the Security Operations Command (ISOC) of the Royal Thai Army, which has allegedly tortured detainees.
