Context:

Mike Waltz, former National Security Advisor to President Trump, was photographed using the TeleMessage app during a Cabinet meeting, which has now suspended its services due to a cybersecurity incident. TeleMessage, acquired by Smarsh, is being investigated by an external firm after the hack, with no details on the extent of data compromised. Waltz was under scrutiny after mistakenly adding a journalist to a sensitive Signal chat discussing a military strike, raising concerns about the app's usage. Following the photograph's release, Waltz was announced to transition from his advisory role to serve as the UN ambassador, pending Senate confirmation. Concerns were raised about the U.S. government using foreign-built technology for sensitive communications, potentially exposing it to foreign intelligence threats.
