US National Security Official Caught Using 'Less-Secure Signal App Knockoff'

Remember when U.S. National Security Adviser Mike Waltz mistakenly included a journalist in an encrypted chatroom to discuss looming U.S. military action against Yemen's Houthis? A recent photo of a high-level cabinet meeting caught Waltz using a "less-secure Signal app knockoff," reports the Guardian: The chat app Waltz was using appears to be a modified version of Signal called TM SGNL, made by a company that copies messaging apps but adds an ability to retain messages and archive them. The White House officials may be using the modified Signal in order to comply with the legal requirement that presidential records be preserved... That function suggests the end-to-end encryption that makes Signal trusted for sharing private communications is possibly "not maintained, because the messages can be later retrieved after being stored somewhere else", according to 404 Media. Thursday the national security adviser was removed from his position, the article points out. He was instead named America's ambassador to the United Nations. Read more of this story at Slashdot.
