- Hacker claims they broke into Messaging Service Telemessage
- Telemessage is a clone of signal, a popular privacy chat app used by JD Vance
- Hacker stole some files from the platform but no US government data was taken
Telemessage, an immediate communication app used by some US government officials, has allegedly been hacked with private messages stolen.
A report from 404 Media Says a hacker broke in and stole messages found on the platform, which was then shared with the publication, enabling it to confirm the authenticity of at least some parts of the stolen archives.
In May 2025, Telemessage received media excess, after it was revealed that Mike Waltz, former US national security adviser, used an unofficial version of Signal called “TM SGNL,” created by Telemessage.
Waltz dismissed
Telemessage is a changed version of the signal app developed by an Israeli company. Pakinomist describes the company as “unclear”.
The app is built as both a company announcement and filing platform for SMS, MMS, voice calls and messages from apps such as WhatsApp, WeChat, Telegram and Signal. The filing is for regulatory compliance and EDISCOVERY purposes.
Now, after hacked, everyone asks the same question – stole the hacker us government communication? The answer is apparently, no.
404 media Says the hacker did not stole any messages from Waltz or anyone else in the Trump administration. We also do not know how the hacker gained access to the information if any zero-day vulnerability was abused or if any malware was implemented in the process.
So far, all parties, including telemessage and the US government, have not commented on the news. A Signal spokesman told Pakinomist that the company “cannot guarantee privacy or security properties for unofficial versions of signal.”
Mike Waltz was dismissed from his role as the US national security adviser on May 1, 2025, after a significant security incident, inadvertently adding journalist Jeffrey Goldberg to a signal group, where senior officials discussed classified military plans for a strike against Houthi militants in Yemen.
