The Cybersecurity and Infrastructure Security Agency (CISA) is recommending that senior government and political officials use end-to-end encrypted messaging applications, such as Signal. This recommendation follows a series of telecom breaches impacting numerous countries, including eight carriers within the United States. The agency's move aims to ensure more secure communications and to prevent potential leaks of sensitive government and political conversations that could arise from these security incidents. These breaches, some of which were confirmed by CISA and the FBI in late October, have highlighted vulnerabilities in the telecom sector. Reports indicate a Chinese-backed threat group, Salt Typhoon, is responsible for the attacks which impacted multiple US telecommunications companies including T-Mobile, AT&T, Verizon, and Lumen Technologies. While the exact timing of the breaches remains unclear, the agency's push for encrypted messaging is a step towards safeguarding sensitive information.
