Messaging apps’ web versions fall short of security standardsAnyone believing that end-to-end encryption makes messaging apps impregnable is sadly mistaken. That’s the bad news. The good news is that it only affects the web versions of the two apps in question – which are arguably the lesser used ones.

Check Point, an Israel-based security firm, has revealed that end-to-end encryption on both the WhatsApp and Telegram instant-messaging services can be bypassed by the simple expedient of hiding HTML code in an innocent-looking image or video.
