The Pentagon's Office of the Inspector General has launched an investigation into the use of a commercial messaging app by the Secretary of Defense and other personnel to ensure compliance with Department of Defense policies for official communications. This probe was prompted by a report revealing that high-profile officials, including Defense Secretary Pete Hegseth, were allegedly discussing sensitive military operations on Signal, raising concerns about security breaches. The investigation highlights the critical need for adherence to cybersecurity protocols in government communications and may influence future policies on using commercial messaging platforms for official purposes.
