You suggest to avoid downloading apps from QR codes. I think that today is almost impossible not to use QR codes. if I receive an email, saying it's from Paypal, I can easily check if it comes from or from a strange address But this distinction can't be done for QR codes, until they're converted. Double check e-mails and messages asking you to pay or log in using a QR know that QR codes are not malicious on their own, but we can't check the URL address until the link is converted by a QR reader.Avoid downloading apps from QR codes, and avoid entering financial data through a site navigated to from a QR code.Once you scan a QR code, double check that the URL looks legit and the domain isn’t just similar to the intended site.When dealing with physical QR codes, always check if they have been tampered with stickers.Avoid installing a QR scanner app on your phone as this exposes you to malware most phones have built-in QR scanners and all you have to do is open your Camera app.Don’t scan random QR codes you find on the street, as there’s a big chance they will redirect you to a malicious website.Of course, it's common sense to take certain precautions when dealing with QR codes and I will name a few: Web Protection offers advanced anti-phishing protection and anti-fraud filtering systems and they come in handy when it comes to QR codes as well. If the URL is fraudulent or contains malware, it will be blocked with the message that Bitdefender has blocked this website. Its Web Protection feature not only filters all Internet traffic by scanning the connections for malicious and fraudulent content intent, but it also blocks malicious URLs that lurk behind a fake QR code. This is where Mobile Security comes into play. When it comes to digitally generated QR codes, things get a little bit more complicated, as hackers need to access the device that generates the QR code or to impersonate a trusted entity. It is well known that hackers can generate a dummy QR code and stick it over real one. Most times you can’t tell if a QR code is genuine or a scam, because the human eye can’t distinguish one QR code from another. QR codes on their own are not malicious in nature, but the URL behind them can be. Thank you for sharing your thoughts with us.
