Hackers are actively targeting a popular Signal messaging app clone, TeleMessage, used by federal agencies.
The clone lacks proper end-to-end encryption and has been exploited by hackers using CVE-2025-48927 and CVE-2025-48928 vulnerabilities.
Around 60 government officials' chats and metadata have been stolen by hackers. CISA has given agencies until July 22 to patch the app.
The app was involved in the Signalgate scandal, where sensitive information was leaked online, leading to the removal of a former national security advisor.
