The four trillion dollars in institutional capital positioned for stable UK-China relations rests on an assumption that died in a Chengdu server room sometime around 2019. The assumption is that espionage between major powers operates within understood boundaries, that telecommunications infrastructure is contested but not compromised, that the surveillance systems Western governments built to watch their citizens cannot be turned around to watch them. The assumption has been falsified. What follows is the complete mechanism of how China’s Ministry of State Security achieved persistent access to the private communications of three British Prime Ministers’ closest advisers, the phones of a US President-elect, and the wiretap systems that were supposed to catch them doing it. The positioning implications are immediate. The framework is permanent.
On January 26, 2026, The Telegraph disclosed that Chinese hackers had penetrated right into the heart of Downing Street, compromising mobile communications of senior officials across the Johnson, Truss, and Sunak administrations. The story was buried on page seven, treated as a technology curiosity. It was, in fact, a solvency event for the Western intelligence alliance. Not because phones were hacked, which happens, but because of how they were hacked: by weaponizing the very surveillance infrastructure that Western governments mandated for their own intelligence agencies. The Communications Assistance for Law Enforcement Act in the United States and the Investigatory Powers Act in the United Kingdom require telecommunications carriers to build backdoors into their networks for court-ordered wiretapping. Chinese state hackers found those backdoors. And walked through them.
The intelligence value is almost impossible to overstate. For approximately four years, operators linked to the MSS’s Chengdu bureau had the capability to see not just who British officials were calling, but whom the FBI was investigating, which Chinese operatives were under surveillance, what the United States knew about Beijing’s activities, and when counterintelligence was getting close. They could geolocate millions of individuals. They could record phone calls at will. They compromised the surveillance of their own surveillers, achieving the counterintelligence equivalent of reading the other side’s playbook while the game was in progress.
What follows is the institutional playbook. The positions are already being built.
The Backdoor That Swung Both Ways
The story of Salt Typhoon is not fundamentally a story about hacking. It is a story about architecture. Specifically, it is a story about what happens when governments mandate that their surveillance systems include single points of failure, then assume those points will only fail in their favor.
In 1994,…
