Scan only QR codes that are risky, trustworthy compared to codes for payment.
Do not scan code other than payment.
How can QR codes be dangerous?
One clarification first - UPI or India QR Code-based payment system itself is completely secure. But it can be dangerous because of our own mistakes. At the same time, the risks are higher in QR codes for other types of use. Such QR codes are ultimately a different form of a link on the Internet. This means that all the risks associated with an Internet link apply to the QR code. If you re-read the other code uses mentioned above, you will understand how this useful feature can be dangerous. The QR code is the Quick Response Code, as its name implies, and just looking at it with the naked eye does not tell us which link it will take us to. So there is a definite risk in inadvertently scanning any QR code. A malicious person can use a code to take us to the wrong web page or download anything to our phone.
Can a hacker hack a QR code?
The original code of UPI cannot be hacked, as it cannot be changed in any way after the link. Whether static or dynamic, other types of code could not be hacked, but the second risk is certain. Even after the dynamic type of code is generated and printed somewhere, the link to which webpage the code will take can be changed. So if the code generating service itself gets hacked or the code generator's teeth get damaged, its code can lead to a new dangerous page. Scanning a code can activate the phone's mic, camera, GPS and give the hacker a live feed. Also, in public places, simple 'hacking' of code can be done by pasting fake code over the real code and leading to a phishing site. On many websites, just by visiting, it is worth remembering that downloading malware can be started without clicking anything.
Can scanning QR codes steal personal data?
If we talk about UPI QR code, by scanning such leprosy, the trader who owns the code only gets tiny details like our UPI ID, transaction ID, last four digits of the bank account. Even in other QR codes, the QR code generating software does not collect any data that reveals the identity of the person scanning it. But all the details of where such QR codes were scanned, from which operating system the device was scanned, when and how many times it was scanned are known to the person who generated the code through the QR code generating service. Has begun to be used. Can. Many restaurants now also have QR codes for menus. Such a code eventually leads to the menu's web page to preserveerve our order details and history.
For safe use of QR codes ...
UPI or India is more than enough to confirm with the shopkeeper the name that is seen, then scan the QR code and checks the amount. Other types of QRs that lead to a link can be dangerous. So do not scan any such code in the blink of an eye. If there is a QR code in a newspaper advertisement or advertisement scam, first check whether the company is trustworthy or not. Be especially careful when scanning codes placed in public places. Usually, the QR code is supposed to write where its link leads us in simple words, be more careful if there is no such text. Fortunately, now scanning the code in most scanners, first see its entire link. Do not scan any code with a scanner that does not facilitate preview. After scanning the code, think carefully before giving any important information on the page that opens.
UPI QR CODE is safe, but it can be broken
UPI or India QR code system itself is completely secure. But hackers take advantage of the fact that people have a half-hearted understanding of the uses of QR leprosy. You will often read in the newspapers that someone lost a large sum of money while trying to sell something on an online site.
The UPI app can generate a certain amount of code and share it through an app like WhatsApp. Just like the UPI app can scan the code in the shop from the camera, it also has the facility to pay by opening the QR code, which is located in some way like WhatsApp and saved in the mobile gallery.
In the case of fraud, the victim has put his old items for sale on a website that sells goods online (or he has to get the money for some reason, like a refund). Hacker Are in search of such prey. He contacts you directly by phone instead of texting. He shows interest in buying your item and then says in the conversation that he is sending us a QR code to pay the amount.
Alarm bells should ring in mind here. The one who is going to take the rupee gives the same QR code, and the one who is going to give the rupee scans the QR code and gives his PIN. People who are victims of UPI QR code fodder misunderstand this. If our item is being sold, the person in front will pay us money, not ask. So he doesn't have to send us a QR code. Instead, the hacker generates a large amount of QR code and sends it to us. If you understand this trick of a hacker, you will not fall prey to QR code fodder.
A new case of fraud with shopkeepers
A new case of UPI QR code fraud has just been reported. A former employee of a UPI app had several QR codes. He connected this code to his bank account and pasted it on the original code sticker in various shops. Many shoppers do not even bother to check a small amount of code payment in their app. The gangster used to stick the wrong sticker in the fixed shop for two to threeree da, saveave the shopkeeper's money in his accou,nt, and then change his prey. Don't stick a sticker outside the store so that you don't fall victim to such fraud. You will benefit from having a QR code with a speaker that will be notified by voice when payment comes from the app.
