The messaging app TeleMessage, used by President Donald Trump’s national security advisor, has been suspended due to a reported security breach, raising concerns about the security of sensitive government communications. The app, a modified version of Signal, was halted after a hacker accessed message contents from its customized versions, although the communications of national security advisor Mike Waltz were reportedly not affected. TeleMessage's suspension follows a statement from its parent company, Smarsh, confirming an investigation into the security incident. Despite President Trump's criticism of Signal, the White House continues to defend it, highlighting its pre-installation on government devices. Concerns about privacy protections arise from TeleMessage's archiving features, which may compromise Signal's end-to-end encryption. Additionally, GlobalX, the airline involved in Trump’s deportation flights, experienced a hacking incident, resulting in the exposure of flight records and passenger lists.
