Chinese Hackers Breach Phones at Heart of Downing Street in Global Spy Campaign

27 January 2026 World

LONDON, England — Chinese state-linked hackers have reportedly breached mobile phones at the very heart of the United Kingdom’s Downing Street, according to multiple reports revealing a sprawling global cyber-espionage campaign. The breaches, which allegedly granted the hackers the ability to record calls, intercept text messages, and track users’ locations, have compromised millions of phone records worldwide, including those of key government officials.

U.S. intelligence officials first detected the campaign in 2024 and subsequently alerted allied nations, uncovering a sophisticated operation targeting telecommunications networks across multiple countries. The campaign has reportedly affected not only the United Kingdom but also the United States and other members of the Five Eyes intelligence alliance, including Australia, Canada, and New Zealand.

According to the Office of the Director of National Intelligence, the hackers exploited vulnerabilities in telecom infrastructure, enabling them to gain unprecedented access to private communications. The breach at Downing Street, the official residence and executive office of the British Prime Minister, underscores the severity of the threat and the potential for espionage at the highest levels of government.

The cyberattack reportedly allowed the hackers to record calls “at will,” raising concerns about the confidentiality of sensitive diplomatic and security discussions. Experts warn that such capabilities could compromise national security and diplomatic relations, as intercepted communications might reveal strategic plans or intelligence sources.

In response, British authorities have launched investigations to assess the extent of the damage and to bolster defenses against future intrusions. The National Cyber Security Centre has been working closely with international partners to identify the methods used by the attackers and to mitigate ongoing risks.

The scale of the operation is vast. Reports indicate that millions of phone users have been affected globally, with hackers gaining access to personal and professional data. The campaign’s reach into multiple countries highlights the growing threat posed by state-sponsored cyber espionage, which increasingly targets civilian infrastructure and government networks alike.

The U.S. Department of Homeland Security has also issued warnings about the risks posed by such cyberattacks, emphasizing the need for robust cybersecurity measures across critical industries. According to DHS Cybersecurity Division, protecting telecommunications infrastructure is vital to national security and economic stability.

This revelation comes amid heightened geopolitical tensions and ongoing concerns about China’s expanding cyber capabilities. Analysts suggest that these breaches are part of a broader strategy to gain intelligence advantages over Western governments and to influence global power dynamics.

The British government has not publicly disclosed detailed information about the breach but has confirmed that it is taking the matter seriously. Officials stress the importance of international cooperation in combating cyber threats and safeguarding democratic institutions.

As investigations continue, experts urge governments and private sector partners to remain vigilant. The incident serves as a stark reminder of the vulnerabilities inherent in modern communications and the critical need for enhanced cybersecurity protocols.
