A security flaw in the Telegram app for Android allowed hackers to use fake videos to secretly install malware on users' phones.
The malware, disguised as a video, would prompt users to download a harmful app that could then access sensitive information on their device.
This could have led to serious consequences like identity theft or data breaches if users fell for the trick.
Fortunately, Telegram quickly patched the vulnerability, so make sure you're using the latest version of the app to stay protected.
