Watch out QR code security

Attacks are everywhere! Just noticed that there're malicious QR code attacks that might trick you into some fake website, or steal information from you. Due to the limited amount information encoded, most of the attacks are either phishing attack or code injection. You really need to pay attention to the website you opened and see if it's as expected. Especially be cautious if you got a prompted form asking for filling out some private info, or asking you to install some package. Best prevention is: only scan those you trust, and ignore those fancy ads on the wall in the streets :)
