US EditionHacker who breached communications app used by Trump aide stole data from across US government
- In early May 2025, a hacker compromised a messaging platform employed by Mike Waltz, who previously served as a national security adviser to President Trump, as well as other U.S. Government officials.
- The breach occurred amid Waltz's recent public scrutiny for previously using Signal and a lack of disclosure about his use of TeleMessage or White House comments.
- Reuters discovered messages linked to over 60 distinct government accounts, including those belonging to disaster response teams, customs officers, diplomats, Secret Service personnel, and individuals working at the White House.
- Jake Williams, a former NSA cyber specialist, said the leaked metadata exposed who communicated and when, posing a "top-tier intelligence access" counterintelligence risk despite some fragments seeming innocuous.
- Following the hack, CISA recommended users discontinue TeleMessage usage and key agencies disabled the service, suggesting serious concerns about the breach's implications for government communications security.
