A Chinese hacking campaign, codenamed “Salt Typhoon” by Microsoft, has infiltrated more than 8 American telecommunications companies, stealing vast amounts of U.S. citizens’ phone data.
Officials describe it as one of the largest intelligence compromises in U.S. history.
The operation, significantly larger than previously known to the public, has affected dozens of countries worldwide and compromised the communications of a large number of Americans.
The cyberespionage campaign has given hackers access to multiple types of information:-
- Call records and metadata, particularly focusing on the Washington, D.C. area
- Live phone calls of specific targets
- Systems used for law enforcement and intelligence agency access (CALEA systems)
While besides this, the analyst at NBC News noted that among the known victims are the presidential campaigns of Donald Trump and Kamala Harris, as well as the office of Senate Majority Leader Chuck Schumer.

Anne Neuberger, a deputy national security adviser, stated that the U.S. does not believe any of the affected telecoms have fully removed the hackers from their systems. This persistent threat poses a risk of ongoing compromises to communications until cybersecurity gaps are addressed.
U.S. officials, along with allies from Australia, Canada, and New Zealand, have released a public guide for telecommunications companies to protect themselves from Chinese hackers. The FBI is in the process of notifying Americans whose calls they believe were compromised, although not all affected individuals will be contacted.
In light of this unprecedented cyberattack, U.S. officials are urging Americans to take precautions:-
- Use encrypted messaging apps for communications
- Consider using cellphones that receive timely operating system updates
- Implement responsibly managed encryption
- Use phishing-resistant multi-factor authentication for email, social media, and collaboration tools
While China frequently denies responsibility for cyberattacks, the U.S. views this campaign as a massive but traditional espionage operation aimed at gathering intelligence on American politics and government.
The compromise has raised concerns about the vulnerability of telecommunications infrastructure and the need for enhanced cybersecurity measures globally.
The incident underscores the critical importance of robust cybersecurity practices and the ongoing challenges in protecting sensitive data in an increasingly interconnected world.
