A Chinese hacking campaign, dubbed "Salt Typhoon," has targeted at least eight U.S. telecom firms, senior government officials, and prominent political figures, compromising private communications in the U.S. and dozens of nations. The White House is urging improved cybersecurity measures like encryption and monitoring to mitigate risks, while impacted firms work to remove the threat actors. China denies the allegations, as federal agencies emphasize the importance of addressing these vulnerabilities to prevent future cyberespionage.
