Unsecured Internet Line Set Up by Hegseth for Signal Connection
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.
A 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.
The biggest advantage of using such a line is that the user would not show up as one of the many IP addresses assigned to the Defense Department — essentially the user is masked, according to a senior U.S. official familiar with military network security.
However, it also can expose users to hacking and surveillance. A “dirty” line — just like any public internet connection — also may lack the recordkeeping compliance required by federal law, the official said.
A ‘dirty’ internet line to use Signal
Hegseth had the unsecured internet connection set up in his office to use the Signal app, which has become a flashpoint following revelations that he posted sensitive details about a military airstrike in two chats that each had more than a dozen people.
Asked about Hegseth's use of Signal in his office, chief Pentagon spokesman Sean Parnell said the defense secretary's “use of communications systems and channels is classified.”
“However, we can confirm that the Secretary has never used and does not currently use Signal on his government computer," Parnell said.
It's the latest revelation to shake the Pentagon. Besides facing questions from both Democrats and Republicans about his handling of sensitive information, Hegseth has dismissed or transferred multiple close advisers, tightly narrowing his inner circle and adding to the turmoil following the firings of several senior military officers in recent months.
Vice President JD Vance told reporters Wednesday about Hegseth: “I have 100% confidence in the secretary.”
