Chinese hackers target U.S. telecoms and steal confidential wiretap data

  • Chinese hackers breached telecom providers, stealing wiretap data and cellular records of U.S. officials.
  • The breach affected tens of millions of Americans, including high-profile targets like Trump and Vance.

What happened

Federal investigators confirmed on Wednesday that Chinese hackers breached multiple telecom providers, stealing sensitive data related to lawful wiretaps. This marks a significant counterintelligence failure. The FBI and CISA disclosed that the hackers also exfiltrated U.S. cellular records and eavesdropped on certain individuals, mostly those involved in government or politics.

Initially, the FBI and CISA did not confirm whether data had been stolen or if surveillance occurred. However, the latest statement revealed that the hackers copied information linked to U.S. law enforcement wiretap requests, which is highly valuable to foreign intelligence services. While the identities of those affected remain undisclosed, it is known that President-elect Donald Trump and Vice President-elect JD Vance were among the targets. The breach is believed to have impacted the cellular records of tens of millions of Americans, though not all were directly surveilled. The number of individuals eavesdropped on has now reached around 40, with the figure potentially rising to thousands.

The breach involved around 10 major telecom providers, including Verizon, AT&T, and Lumen, and is regarded as one of the most serious cyberattacks in recent history. The investigation continues, with classified briefings provided to congressional committees. This intrusion adds to the growing list of Chinese-backed cyberattacks on U.S. agencies and infrastructure.

Why it is important

This breach is critical as it exposes serious flaws in U.S. telecom infrastructure and highlights the growing threat of state-sponsored cyberattacks. By stealing sensitive wiretap data, including law enforcement requests, the hackers accessed highly valuable information for espionage. The breach compromises the privacy of individuals, including political leaders, and undermines national security efforts. The theft of cellular records from tens of millions of Americans further magnifies the scale of the attack. The involvement of major telecom providers, such as Verizon and AT&T, shows the widespread nature of the threat. This incident is part of a larger pattern of Chinese-backed cyberattacks targeting U.S. agencies. It marks a dangerous escalation in the cyber conflict between the two nations.
