Information collected during the yearslong Salt Typhoon attack could allow Beijing’s intelligence services to track targets from the United States and dozens of other countries.
China has hacked into American power grids and companies for decades, stealing sensitive files and intellectual property such as chip designs as it seeks to gain an edge over the United States.
But a sweeping cyberattack by a group known as Salt Typhoon is China’s most ambitious yet, experts and officials have concluded after a year of investigating it. It targeted more than 80 countries and may have stolen information from nearly every American, officials said. They see it as evidence that China’s capabilities rival those of the United States and its allies.
