What Are QR Codes?
QR codes (Quick Response codes) are two-dimensional barcodes that can store information like website
URLs, contact details, or Wi-Fi credentials. They are convenient and widely used for quick
access to information.
Why You Should Be Cautious
While QR codes are convenient, they can also pose security risks. Scanning an unknown QR code can
lead to:
- Accessing malicious websites that steal your data.
- Triggering unintended actions like sending emails, making payments, or sharing personal
information.
- Installing malware or tracking software on your device.
How This Relates to Unknown Links
QR codes are essentially shortcuts to links. The dangers of clicking unknown links apply to scanning
unknown QR codes:
- If you don’t trust the source of the QR code, you shouldn’t scan it.
- Verify the URL preview (if your scanner shows one) before proceeding.
- Be wary of QR codes in public places or sent by unknown individuals.
Protect Yourself
Here are some simple tips to stay safe:
- Use a QR code scanner that checks URLs for security threats.
- Never scan QR codes from suspicious or unverified sources.
- Enable URL previews to see where the QR code leads before opening it.
