The US cybersecurity watchdog, CISA, is advising citizens to use secure end-to-end encrypted messaging apps like Signal.
CISA released best practices in response to the Salt Typhoon attack, urging people to switch to Signal-like apps for secure communications.
CISA recommends evaluating the extent to which messaging apps collect and store metadata, enabling phishing-resistant two-factor authentication, and using strong password managers.
They also advise against using unsecured commercial VPN services and recommend choosing reputable VPN apps with strong security features.
