“암호화 무의미” 100만 다운로드 보안 메신저의 최악의 취약점

TeleGuard, an app that markets itself as a secure, end-to-end encrypted messaging platform which has been downloaded more than a million times, implements its encryption so poorly that an attacker can trivially access a user’s private key and decrypt their messages, multiple security researchers told 404 Media. TeleGuard also uploads users’ private keys to a company server, meaning TeleGuard itself could decrypt its users’ messages, and the key can also at least partially be derived from simply intercepting a user’s traffic, the researchers found. The news highlights something of the wild west of encrypted messaging apps, where not all are created equal. 💡 Do you know anything else about this app or other security issues? I would love to hear from you. Using a non-work device, you can message me securely on Signal at joseph.404 or send me an email at joseph@404media.co. “No storage of data. Highly encrypted. Swiss made,” the website for TeleGuard reads . The site also says, “The chats as well as voice and video calls are end-to-end encrypted.” This post is for paid members only Become a paid member for unlimited ad-free access to articles, bonus podcast content, and more.
