Defense Secretary Pete Hegseth has reportedly implemented a workaround that enables him to access encrypted messages via the Signal app while at his office, raising significant security concerns. Sources informed CBS News that the system established allows Hegseth to remotely view messages from his personal cellphone without adhering to standard Defense Department security protocols.

Details of the Setup

According to insiders, a computer monitor was installed in Hegseth’s office, enabling him to check messages sent to the Signal app and respond directly from his desk. This system reportedly facilitates access to Hegseth’s personal iPhone messages even when his device is not physically present in the office.

In addition, an unsecured internet connection, commonly referred to as a “dirty line” in IT and cybersecurity circles, was reportedly utilized to bypass standard security measures, thereby exposing the system to possible vulnerabilities that could be exploited.

Official Denials and Security Implications

A Defense Department spokesperson refuted claims concerning the existence of a “dirty line” and any ongoing use of Signal within Hegseth’s office. They clarified that a physical line connects a monitor to Hegseth’s phone, located immediately outside the office. Furthermore, the setup is reportedly intended to be a one-way line that only alerts him of incoming messages.

This situation gains additional complexity as the office in which Hegseth operates is classified as a Sensitive Compartmented Information Facility (SCIF), where personal cellphones are typically prohibited. Sources reiterated that this operational workaround poses considerable security risks.

Controversial Information Sharing

This week, Hegseth faced backlash for allegedly sharing details regarding impending U.S. airstrikes in Yemen through a private Signal group chat. This chat included personal contacts such as his wife, brother, and attorney—individuals not necessarily entitled to receive sensitive military information. This incident marks the second instance of such sharing within different Signal group chats.

A Marine Colonel, Ricky Buria, an aide in Hegseth’s office, was reportedly involved in organizing internet connectivity solutions during the initial phase of the administration and had oversight on the setup enabling Hegseth’s access.

Understanding Signal and Its Usage

Signal is an end-to-end encrypted messaging platform renowned for its security features. It includes a desktop application that seamlessly connects to a mobile device via a QR code, mirroring messages to allow for an efficient communication experience.
