What is Quishing?
Quishing, short for "QR code phishing," involves using QR codes to deceive victims. Here's how it works:
Cybercriminals generate seemingly harmless QR codes that lead to fraudulent websites or initiate downloads of malicious software. These malicious QR codes can be distributed via emails, social media, printed materials, or even by placing stickers over legitimate QR codes in public spaces.
When someone scans the malicious QR code, they are directed to a deceptive website. The site may appear legitimate, offering discounts, special deals, or other enticing content. However, victims are unwittingly prompted to provide sensitive information, such as login credentials or financial details. In some cases, malware is downloaded, compromising the victim's device and network.
Recent Trends
One notable trend involves the use of crypto ATMs and QR codes. The FBI has reported an increase in scammers instructing victims to use physical crypto ATMs for payment transactions. Fraudsters manipulate victims into making payments and guide them to cryptocurrency ATMs. The given QR code automatically fills in the recipient's address, making the process seem legitimate.
Prevention Tips
Be Cautious: Only scan QR codes from trusted sources. Avoid scanning random codes in public places. Double-check the URL before providing any information on a website. If something seems too good to be true, it probably is.
Use a QR Code Scanner App: Opt for a reputable QR code scanner app that checks URLs for authenticity. Some apps provide warnings if a code leads to a suspicious site.
Stay Informed: Keep up with security news and trends. Educate yourself and your team about the risks of quishing.
Moving Forward
QR codes—those pixelated portals to convenience—can also harbor danger. As you scan, tread cautiously. Verify sources, question context, and guard your trust. Remember, not all codes lead to safety.
