Since QR code phishing works both analog and digital, you should not place unlimited trust in QR codes.
QR codes can now be found in more and more areas of everyday life. Whether you want to store a vaccination certificate in one of the many Corona apps, scan a bank transfer or call up web content - the square code is used everywhere. The way the QR code works is very simple: all you have to do is scan it using a QR code scanner or your cell phone camera - then you can access the service offered. At first glance, this makes the code a valuable companion in everyday life. At the same time, the very ease of use invites cybercriminals to commit QR code fraud.
There are many ways for fraudsters to access your login data. A lesser known and newer method is QR code phishing. This is a form of QR code fraud that can be placed directly in an email. You don't have to download an attachment or click on a link, just scan the QR code. For criminals, such QR code scam has the advantage that many security solutions can be bypassed quickly and easily. A major problem with QR code fraud is that cybercriminals gain access to your smartphone. The reason is simple: while companies have numerous security measures in place, most mobile devices are not part of the protected infrastructure. Most users trust that their phones are safe and have no software to warn them. Although mobile app pentests can detect such a threat, many users are unaware of the potential dangers. Since QR code scam works both analog and digital, you should not trust QR codes without limits. In QR code phishing, then the small square leads them to a fake website, for example. Criminals prepare these websites so skillfully in advance that they look deceptively real. If you then enter your login data for your accounts or other services, the fraudsters have an easy job. This is because cybercriminals can intercept your input and steal your data. Whether you notice the QR code fraud directly depends on what the attackers have planned. However, if it is the entry of your bank or financial data, the fraud quickly becomes obvious. Alternatively, QR codes sent via email or postal mail can be used to install malware. Hidden applications allow the scammers to access your mobile devices. The result is that you can read your personal data. Since many places lack the necessary security measures for mobile devices, QR code scam can have devastating consequences.
QR code scanner is a way to retrieve QR code content. Such scanners can be conveniently installed via the app store and help in many everyday situations. Despite tighter security measures in the stores, cybercriminals may provide the often free apps. Even legitimate offers can contribute to QR code phishing due to the ads they display. The following risks are associated with the use of a QR code scanner:
To prevent QR code fraud, it is important that you take the necessary security measures. After all, it's almost impossible to tell which app may bring dangers or which QR code is designed to commit fraud.
So-called pentests protect you and your company not only from QR code fraud, but also from potential malware. What exactly the IT security penetration test looks like depends on your specific project.
For all pentests, we take care to adhere to the most important standards in order to contribute to the greatest possible cybersecurity. One basis for this is the PTES. Here we have explained the Penetration Testing Execution Standard (PTES) in simple terms. The cost and pricing for a pentest can vary greatly depending on the infrastructure at hand. A direct inquiry allows to estimate the necessary effort in advance and to calculate both accordingly. Tip: In addition to these specialized test variants, the six Linux distributions for penetration testing can help you identify vulnerabilities.
