UK Foreign Office: UK Suspects Chinese Involvement in Foreign Office Cyberattack

UK Foreign Office Hit by Suspected Chinese State-Backed Cyberattack

In October, the UK Foreign Office suffered a cyberattack believed to have been carried out by Chinese state-backed actors. The breach, first reported by The Sun, involved unauthorized access to thousands of documents, though UK officials downplayed the risk to individuals.

Trade Minister Chris Bryant confirmed the incident in a series of interviews, stating that the vulnerability was swiftly addressed. While Bryant did not directly attribute the attack to China, anonymous British officials indicated that Chinese-linked actors were the prime suspects, though formal attribution has not yet been made. The UK government acknowledged the breach in a statement, emphasizing its commitment to cybersecurity.

The attack occurs amid strained UK-China relations, marked by previous cyber incidents, espionage concerns, and Beijing’s crackdown on Hong Kong’s democracy. Despite tensions—including Prime Minister Keir Starmer’s recent criticism of the conviction of Hong Kong media mogul Jimmy Lai—the UK continues to balance engagement with China, with Starmer set to visit the country next month.

The Foreign Office breach follows other high-profile cyberattacks in 2024, including disruptions at Jaguar Land Rover and Marks & Spencer. Bryant noted that such incidents are now an expected challenge in modern security landscapes. The UK has also faced delays in approving a proposed Chinese embassy in London, citing security concerns over its proximity to critical financial and telecommunications infrastructure.
