Consider QR code is a gate to open something. If click on it, you will be direct to a potential threat, it is risky and I would like to avoid it.

If I am directed to a phishing website, will I lose my money?
Yes or No, it depends on what I will do on that website but prevention is better than cure. If I can avoid potential threats at a first step, I will prioritize it than jumping into a hold and try to do my research to escape from it.

usually, the QR code will display the URL first before we agree to continue to the web destination. perhaps some devices are set to log in automatically after scanning the code.
but if there is no contact with the phishing website such as transaction approval or wallet exchange, I don't think it will be a problem.
To avoid this, we should not carelessly connect our devices with just any QR code scan. or if we access our wallet via smartphone, maybe we can use it separately from the device we use for social activities.

it needs to be auto-executable once you have scanned the QRcode, but the question is can you get yes, once redirected to the link being attached to the QR if you have accidentally clicked it, then its game over, especially if you are using phone that you never updated once they are available, that is why phone have updates since they need to fix the bugs and issues that may cause hackers to use those holes to get in to your phone.

This is a bit misleading, because if the QR code contains a link to a malicious website, and your phone is configured to automatically open the website after your scan the code, then you will instantly get infected if the malware is able to work on your device. So we must be careful about what we scan and make sure we can view the full URL (or at least the protocol and website if applicable).

There's a possibility of getting Malware on phone through QR code scanning if the link provided after the code scanning is coded in a way that will redirect users to websites or links that are malicious.
I think we just need to take extra caution when dealing with online activities because technology is advancing every day and online theft is implementing new strategies.

You are correct. But no link is altered through the QR code, but a link is altered by itself before generating the QR code which is a link to download malware. QR code itself is safe. About taking extra caution, anything you paste with QR code, you have to check and recheck that thing, making sure it is correct before proceeding.

I don't think a QR code in itself can execute code or open/download links — you'll need to do the action yourself after scanning the QR code. Scanning a QR code is like typing in a website URL on your browser without pressing the 'enter' button yet.

Now when you scan a QR code with your phone, is it possible to get malware on your iphone just from scanning it? I am not that familiar with QR codes but I believe once you bring your camera to it, it automatically goes to that website without you clicking take a picture or not?

If you have a crypto wallet on your phone, can you get malware this way? Now if it's a popular store or place, then chances are almost none? But could a hacker change that QR code to malware somehow even if it directs you to the correct site?

I read from several sources, including antivirus provider blogs. In general, QR codes themselves are safe because they have no intrinsic security risks; This means that when you scan it, your device will not immediately be exposed to viruses or malware.

The risk of getting a virus or malware is when you carry out a further process by clicking on a link obtained through a barcode scan, which could have been manipulated by scammers, for example, in the form of a link containing malware which is automatically downloaded or installed when you click on the link.

Quote from: www.eset.com - Best Practices When Scanning and Using QR Codes

But first, are QR codes safe? In short, yes. QR’s themselves are safe as they don’t have any intrinsic security risks. However, other elements involved in the use of QR codes, such as mobile devices do. Although unlikely, there are several ways that cybercriminals can utilise QR codes to access private data. As such, it’s important to be aware that mobile devices are still at risk when they scan a QR code and there are several ways attackers can use QR codes as a ploy.

Quote from: www.malwarebytes.com - Are QR codes safe?

While QR codes are generally safe, they can be manipulated by scammers because they all appear similar. A malicious QR code may lead you to a spoofed website designed to drop different malware types or steal your sensitive data, like your login credentials, credit card information, or money. In one incident, scammers were using fake parking meter QR codes to steal money through phishing websites.

There are some threats from QR code and when you are on Internet, you have to practice a general rule, don't be too curious and want to explore every new things you see. If you do this, your curiosity will put you and your devices at bigger risk.

How cybercriminals mask QR codes

If you are worrying about it, with the question in OP, you seem to be careful enough and it is a prevention for potential cyber security issues.

You can not get malware through QR code.

QR code also help against clipboard malware because there is nothing to copy to clipboard.

But if you are using QR code for payment, always check and recheck the payment address to make sure that you are sending coins to the right address. It is good to always still assume that hack can happen.

I think what you think is possible I can generate a QR code with different links but redirect them to different sites.

Sample you made a site and adding HTML redirect to the site of your choice under headings and then generate the QR code of your site that you can share with anyone if someone scans the QR code they will redirect to a different site.
You can add malware to your site to infect the users who access your site.

So be careful to scan any QR code make sure to use antivirus to scan the QR code or use the QR Kaspersky scanner or just download the Kaspersky app it has a feature to scan the QR code.

So I know lot of places have you scan a QR code to visit a site and things like that. I believe they do that with restaurants as well or not?

Now when you scan a QR code with your phone, is it possible to get malware on your iphone just from scanning it? I am not that familiar with QR codes but I believe once you bring your camera to it, it automatically goes to that website without you clicking take a picture or not?
