QRLJacking — Hacking Technique to Hijack QR Code Based Quick Login System
Jul 28, 2016
Do you know that you can access your WeChat, Line and WhatsApp chats on your desktop as well using an entirely different, but fastest authentication system? It's SQRL , or Secure Quick Response Login, a QR-code-based authentication system that allows users to quickly sign into a website without having to memorize or type in any username or password. QR codes are two-dimensional barcodes that contain a significant amount of information such as a shared key or session cookie. A website that implements QR-code-based authentication system would display a QR code on a computer screen and anyone who wants to log-in would scan that code with a mobile phone app. Once scanned, the site would log the user in without typing in any username or password. Since passwords can be stolen using a keylogger, a man-in-the-middle (MitM) attack, or even brute force attack, QR codes have been considered secure as it randomly generates a secret code, which is never revealed to anybody else.
