The great diffusion of QrCodes sees the interest of cybercriminals, who let nothing escape to carry out their attacks.
Widely used in both business and private sectors, QrCodes today represent a cyber threat that should not be underestimated, a means used by cyber criminals to carry out violations and install viruses, Trojans and even ransomware. With the pandemic, for example, a sector such as catering has been practically forced to digitize itself, with digital menus accessible via QrCode to avoid contacts. With readers now present on all mobile devices, QrCodes have passed to be used for many different uses, including payments, for easy access to online resources: websites, documents, applications.
Origin and history of QrCode.
These codes date back to 1994. The Qr stands for Quick Response, so they are quick response codes. Their inventor, a Japanese who produced car components, invented them precisely to track vehicles during the various stages of production. In fact it is a barcode that offers a large storage capacity, which is an excellent means of transmitting data.
How safe are QrCodes?
Obviously, the development and diffusion of this technology has meant that it became the target of hackers, always looking for new methods to carry out cyber attacks. So the dark web quickly became populated with discussions on how to exploit this development, to the point of providing open source tools and videos to illustrate how to carry out attacks through QrCode.
