A group of researchers based in London have revealed that the popular messaging application Telegram had some serious security flaws. Telegram, one of the best WhatsApp alternatives, has over 500 million users on both iOS and Android operating systems.
The Royal Holloway researchers suggested that Telegram had vulnerabilities in Cloud Chats. The platform, by default, offers non-E2EE (End to End Encryption) chats while the users who are more worried about their privacy can always opt-in for End to End Encryption for individual chats. The vulnerabilities were found in non-E2EE chats.
