Quick Response codes are a widespread feature commonly used to conveyinformation to users who scan them. During Covid 19 these codes became evenmore widespread as restaurants had to adapt to using contactless visits to hinder thespread of the disease, but since quick response codes can also be leveraged formalicious purposes the number of phishing attempts also increased. In this thesis, weexplored the security implications of QR codes by investigating how they can beexploited and secured, as well as surveying how aware people are of these securityimplications.

The result of the thesis shows that QR codes can be leveraged to send maliciousprograms directly through the QR code without having to download anything.Through the survey we learned that people are relatively unaware of phishingthrough QR codes, but also that some of the participants knew someone who hadbeen a victim of it.
