Cyber Threat Actor: United Kingdom

The threat actor is publicly referenced under the alias “United Kingdom” and is known to operate from within the United Kingdom. Attribution to UK authorities emerges from the Encrochat compromise, where a source controlling an Encrochat‑associated email address told Motherboard that the hacking operation appeared to originate in the UK and noted the lack of comment from the UK’s National Crime Agency. The same actor was implicated by Geert Wilders in the December 2022 cyber attack on the PVV website, which he described as a “massive” assault routed through or originating from the United Kingdom among other countries.

Targeting observed includes encrypted communications platforms used by criminal networks and a political party’s online presence. In the Encrochat case the actor focused on a service that sold customized phones with removed GPS and camera functions, remote‑wipe capability, and exclusive inter‑device messaging, affecting users across Europe. The PVV website attack targeted a Dutch political organization, causing extended downtime and intermittent access for its supporters. Strategic objectives evident from the incidents are the disruption of service availability—Encrochat was permanently shut down after the malware deployment—and the collection of intelligence that facilitated widespread arrests by law enforcement agencies.

Noted tactics, techniques, and procedures involve the deployment of stealthy malware designed to evade detection, disable factory reset functions, record screen‑lock passwords, and clone application data on compromised devices. The actor pushed a software update to affected X2 models, then observed a follow‑on attack that prompted warnings to users to discard their Encrochat handsets. Initial access appears to have been achieved through a takeover of part of the company’s infrastructure, after which the malicious payload was launched against the devices themselves. No specific malware families or tool names are disclosed beyond the described capabilities, and the actor’s affiliations are limited to the public statements linking the operation to UK law enforcement entities without further detail on internal structure or broader criminal consortium ties.

Representative operations include the 2020 Encrochat infiltration that led to the service’s shutdown and subsequent pan‑European arrests, and the 2022 disruption of the PVV website that was publicly attributed in part to the United Kingdom. These cases illustrate the actor’s focus on undermining secure communications channels and political online assets through infrastructure compromise and custom malware deployment.
