In response to a large-scale cyberespionage campaign targeting major telecommunications companies, including AT&T and Verizon, U.S. officials have recommended Americans adopt encrypted communication tools to protect sensitive information. Dubbed "Salt Typhoon" by Microsoft, the campaign represents one of the most significant intelligence compromises in U.S. history.
The hackers, believed to be linked to China, accessed call metadata, live phone calls, and sensitive systems used for law enforcement compliance. Officials from the FBI and Cybersecurity and Infrastructure Security Agency (CISA) emphasized encryption as a critical defense against cyber threats, advising the public to use apps like Signal, WhatsApp, and iMessage that provide end-to-end encryption.
Encryption: The First Line of Defense
"Encryption is your friend," said Jeff Greene, executive assistant director for cybersecurity at CISA. “Even if the adversary intercepts the data, strong encryption can make it unreadable.”
In addition to encrypted messaging, officials recommended securing mobile devices with timely operating system updates and multi-factor authentication to enhance protection against phishing and other cyber threats.
