Overview of Salt Typhoon Hack Campaign

Salt Typhoon represents a significant espionage campaign from China targeting U.S. telecommunications providers. It has been active for at least a year, compromising multiple companies, including major firms like AT&T and Verizon. This campaign resulted in the theft of sensitive metadata related to calls and text messages, impacting not only private citizens but also high-ranking government officials. Recent confirmations revealed that the hackers had the capability to read SMS messages and could listen in on phone calls, raising serious concerns about national security.
