A hacker breached TeleMessage, a messaging app used by members of the Trump administration and US government officials, in a quick attack that reportedly took 15 to 20 minutes. The breached materials included sensitive data related to Customs and Border Protection (CBP) and cryptocurrency exchange Coinbase. A screenshot from the control panel showed names, phone numbers, and email addresses of CBP employees, indicating access to data of hundreds of US government personnel. Michael Waltz, the recently dismissed national security adviser, was noted to have used TeleMessage during a cabinet meeting.
