In this modern era, using QR codes has become a common practice, which is often used to open websites, download applications, collect loyalty program points, make payments and transfer money, or for charity.
This technology that is easy to access and practical is undeniably very convenient for many people, including cybercriminals who have launched various QR-based schemes.
You need to know QR code is just a more advanced version of barcode. Although more sophisticated, in fact there are quite a lot of cybersecurity gaps and very risky, and we can’t just read the QR code or check the scanning process, so the user can only rely on the integrity of the creator, so the system is very easy to exploit.

And it’s likely that the fake QR Code link created by the cybercriminals leads to a phishing site that looks like a social network or online bank login page.
That’s why security experts at Kaspersky recommend checking links all the time, moreover cybercriminals also frequently use short links, making it harder to spot a fake when a smartphone asks for confirmation.
Then with a similar attack scheme, cyber criminals also often trick users into making mistakes in downloading applications, for example, initially wanting to download a game instead they are directed to download malware. At that point, the malware can steal passwords, send malicious messages to your contacts, and much more.
In addition to linking to a website, QR codes may now contain commands to perform certain actions, such as adding a contact, making outgoing calls, drafting an email and collecting message recipient and subject lines, sending text to creating social media accounts.
Its broad capabilities make QR codes ready and very easy to manipulate. For example, online fraudsters can add their contact info to your address book under the name ‘Bank’ to give credibility to calls trying to trick you.

So what you need to pay attention to is that apart from this cyber attack, remember that cybercriminals will always try to get QR code access with convincing offers and placements, for example being saved on a website, banner, email link, or even in an advertisement on a paper. The point is to make the victim download a malicious application. In many cases, the Google Play and App Store logos are also placed next to the code to make it more convincing.
What you need to do first is, don’t scan QR codes from sources that are clearly suspicious, pay attention to the links displayed when scanning the code. Then be careful if the URL has been shortened, because with a QR code it is not possible to shorten any links.
Then do a quick physical check before scanning the QR code on the poster or sign to make sure the code is not pasted over the original image.
