Pentagon Report Finds Defense Secretary Hegseth’s Signal Use Potentially Risky

A new report from the Department of Defense office of Inspector General reveals that Defense Secretary Pete Hegseth may have compromised the safety of American troops by using the Signal app to discuss military strikes in Yemen. The 84-page report, released on December 4, 2025, details how Hegseth’s actions violated department policies regarding secure dialog.

Key Findings of the Inspector General Report

The inquiry centered on Hegseth’s use of a commercial messaging application – Signal – and his personal device to communicate sensitive information. the report confirms that this practice did not align with established Department of Defense protocols for secure communication.

Details of the Security Breach

according to the report, Hegseth transmitted details about the number of aircraft and precise strike times for US military operations in Yemen over an unapproved and insecure network. This information was sent approximately 2 to 4 hours before the strikes were executed.

“The Secretary sent information identifying the quantity and strike times of manned US aircraft over unfriendly territory over an unapproved, unsecure network approximately 2 to 4 hours before the execution of those strikes.”

Policy Violations

The use of unapproved communication channels like Signal presents several risks:

• Lack of Encryption: While signal offers end-to-end encryption, using it outside of DoD-approved systems bypasses the department’s robust security infrastructure.
• Data Interception: Unsecure networks are vulnerable to interception by adversaries.
• Compliance Issues: hegseth’s actions directly contravene DoD policies designed to protect sensitive military information.

Potential Risks to Troop Safety

The timing and nature of the information shared raise serious concerns about potential risks to US troops. Providing details about aircraft numbers and strike times to an unsecure network could have allowed adversaries to anticipate and potentially counter US military operations, endangering personnel.

The Importance of Secure Communication

Maintaining secure communication channels is paramount in modern warfare. The DoD invests heavily in secure systems to protect sensitive information and ensure the safety of its personnel. Bypassing these systems, even with the intention of expediency, can have severe consequences.

Report Release and Previous Leaks

The findings of the report were leaked to the press prior to its official release on Thursday. The Department of Defense has not yet commented on potential disciplinary actions related to the findings.

Key Takeaways

• Defense Secretary Hegseth used the Signal app to discuss military strikes in Yemen.
