TM SGNL Shut Down: When Secure Messaging Apps Get Hacked and Go Haywire!
TM SGNL, a chat app by TeleMessage, is temporarily out of service after a data breach exposed sensitive messages and backend data. This breach has raised eyebrows due to the app’s use by Trump officials. What’s next? Smarsh, its corporate owner, is reportedly rebranding the service as Capture Mobile.

Hot Take:
Who knew a chat app supposedly used by high-ranking government officials could be breached quicker than a teenager hacking a Wi-Fi password? TM SGNL, it seems, has left the chat. Maybe next time they’ll consider using two-factor authentication or at least a good ‘ol tin can and string for those top-secret conversations.
Key Points:
- TM SGNL, a chat app used by US government officials, suffered a data breach.
- The hacker accessed messages and backend data within 20 minutes.
- Security flaws included hardcoded credentials and unencrypted message storage.
- The app has been temporarily suspended following the breach.
- TeleMessage is rebranding the service as Capture Mobile, sans references to the app.
