US official advises encryption amid alleged Chinese hacking efforts

A senior United States cybersecurity official has urged Americans to embrace encryption to safeguard their communications, citing ongoing efforts to expel alleged Chinese hackers from US telecom networks. Jeff Greene, Executive Assistant Director for Cybersecurity at the Cybersecurity and Infrastructure Security Agency (CISA), emphasised the importance of avoiding plaintext communications and recommending encrypted apps like Signal and WhatsApp.

US authorities have accused hackers from China of infiltrating telecommunications companies, such as T-Mobile, to access sensitive data, including call records and intercepted audio, predominantly from Washington, DC. Beijing has denied the allegations, calling them disinformation. Greene acknowledged that removing the hackers entirely from the networks could take an unpredictable amount of time, further underscoring the need for encryption to ensure secure communications.

The advice marks a notable shift from previous US government positions that questioned strong encryption’s impact on public safety. As concerns over foreign cyber intrusions grow, Greene’s remarks highlight encryption as a critical tool for Americans facing prolonged cybersecurity threats.
