For any new users who left WhatsApp for Telegram, the latest glitch is a stark reminder that, unfortunately, no messaging service is completely secure.
The latest privacy-defeating vulnerability was unearthed by security researcher Dhiraj Mishra. It’s found in version 7.3 of the macOS app. Telegram was notified about the issue on December 26, 2020. And following an update on January 29, the issue has been resolved in version 7.4 of the macOS app. Mishra has allowed enough time for most users to update their app before speaking publicly about the bug – but if you haven’t yet updated Telegram on your MacBook, iMac, Mac Pro or Mac mini, you’ll want to head to the App Store to download that right away.
