TeleMessage, a messaging app used for archiving communications, is currently under investigation for a potential security breach. The app was reportedly used by former National Security Adviser Michael Waltz, who was photographed sending messages to other officials in the Trump administration.
A spokesperson for TeleMessage confirmed the investigation and announced that the app’s services have been temporarily halted. The company, which is based in Portland, Oregon and owned by Smarsh Inc., allows users to archive messages from popular encrypted apps like Signal, WhatsApp, and Telegram.
The breach was first reported by 404 Media, which stated that hackers accessed and stole some direct messages and group chats from the platform. In response to the incident, TeleMessage acted quickly to contain the situation and has hired an external cybersecurity firm to assist with the investigation. Despite the suspension of TeleMessage services, all other products from Smarsh remain operational.
Waltz’s use of messaging apps has been under scrutiny before. In March, he accidentally included Atlantic editor Jeffrey Goldberg in a Signal group chat discussing military plans against Houthi rebels in Yemen. This incident reportedly influenced President Donald Trump’s decision to remove Waltz from his national security role and instead nominate him as ambassador to the United Nations.
The company has not provided further details about the breach or the ongoing investigation.
