Defense Secretary Pete Hegseth had an internet connection that bypassed the Pentagon’s security protocols set up in his office to use the Signal messaging app on a personal computer, two people familiar with the line told The Associated Press.

The existence of the unsecured internet connection is the latest revelation about Hegseth’s use of the unclassified app and raises the possibility that sensitive defense information could have been put at risk of potential hacking or surveillance.

Known as a “dirty” internet line by the IT industry, it connects directly to the public internet where the user’s information and the websites accessed do not have the same security filters or protocols that the Pentagon’s secured connections maintain.

Other Pentagon offices have used them, particularly if there’s a need to monitor information or websites that would otherwise be blocked.
