常見問題(FAQ)
How are QR codes used for phishing?
A common QR code phishing tactic is disguising QR codes as legitimate, leading users to false login pages designed to steal your credentials.
Fake QR codes could also take you to phishing sites asking for your credit card information to “verify your identity” before claiming a supposed discount.
How can users distinguish between legitimate and malicious QR codes?
With many QR code scanners, you can preview the encoded URL before actually scanning it, giving you a good idea of where it might lead.
A suspicious URL might have misspelled website names or generic domain extensions (i.e., .info, .biz).
Can you get a virus from a QR code?
The QR code itself cannot directly transmit a virus, but the data it holds can be laced with a malicious URL that leads to a website with malware.
How can an attacker use a QR code?
Attackers can exploit QR codes in various ways. For example, they could steal your information, infect devices with malware, or launch phishing attacks.
Malicious QR codes can also be used to connect users to fake Wi-Fi networks, potentially intercepting your internet traffic or stealing sensitive information.
