Reports have surfaced indicating that Chinese state-affiliated hackers infiltrated mobile phones in central Downing Street as part of an extensive cyber-espionage effort targeting global telecommunications. According to findings released in 2024, U.S. authorities uncovered that a group had breached telecom companies worldwide, prompting them to notify allies for the first time.
This cyber campaign reportedly affected various nations, notably the United States and partners within the Five Eyes intelligence alliance—Australia, Canada, and New Zealand. The breach is believed to have provided China with access to an extensive database of phone users, raising alarms about potential eavesdropping on calls, reading text messages, and tracking user locations.
Former U.S. National Security Advisor Anne Neuberger mentioned that hackers had the capability to record calls whenever they wanted. She noted that this access allowed China to locate millions of individuals and listen in on their communications. Although U.S. intelligence suspects the breach started as far back as 2021, it wasn’t publicly identified until 2024.
In response to the threat, federal authorities advised telecom companies to bolster their network security, a measure intended to root out malicious actors and prevent such attacks in the future. The U.S. National Security Agency, in collaboration with its allies, also issued warnings regarding Chinese state-sponsored attacks, emphasizing the overlap with previously reported activities connected to a group known as Salt Typhoon.
Concerns have been raised in the UK regarding the possible exposure of senior officials due to this breach. Sources indicated that the infiltration reached deep into the government’s inner circles. There have been many instances of hacking directed at mobile phones within the UK government, particularly during Rishi Sunak’s time as Chancellor between 2022 and 2024, which highlights a troubling pattern.
Cybersecurity experts, including former Israeli intelligence chief Yuval Wolman, noted that Salt Typhoon is a significant player in international cyber operations. While much attention has been placed on targets in the United States, this group’s activities have extended to Europe, the Middle East, and Africa, often focusing on telecommunications companies and governmental institutions.
Amid these revelations, China’s Ministry of Foreign Affairs has dismissed the allegations as unfounded and lacking evidence. Meanwhile, inquiries have been made for comments from Downing Street regarding this critical security issue.
