In February 2025, the NSA issued a bulletin warning about vulnerabilities in the encrypted messaging app Signal, following an incident where sensitive military plans were accidentally shared with journalist Jeffrey Goldberg via the app. This incident, involving Defense Secretary Pete Hegseth and a Signal group chat discussing military operations in Yemen, has raised concerns about the app's suitability for sensitive government communications. The disclosure has sparked a broader debate on the security of encrypted messaging applications and the need for stringent operational security measures to prevent similar breaches in the future.
