In a recent incident, US national security adviser Mike Waltz unintentionally added journalist Jeffrey Goldberg to a private Signal group discussing potential military strikes in Yemen due to a phone contact error. This error was caused by an auto-save feature on Waltz’s iPhone, leading to a White House investigation. Despite no classified information being leaked, the situation reportedly upset President Trump. However, Waltz was not fired as a consequence of the mistake. The incident sheds light on the importance of safeguarding sensitive information and the potential risks associated with technological features like auto-save.
