How to Protect from Quishing – QR Code Scam

Let’s understand what is quishing and how to protect from this QR code scam attack. In today’s digital world, cyber-criminals use many tricks to steal information or harm users. One of the newer and growing threats is Quishing. It is important to understand what Quishing is, how it works, and how to protect yourself from it.

What is Quishing?

Quishing is a type of phishing attack where scammers use QR codes to trick people into visiting malicious websites. Instead of sending links through emails or messages, they create a QR code that hides the dangerous link. When users scan the QR code, they are unknowingly directed to fake websites that steal their personal information.

Quishing (QR Code Phishing) is a cyber-attack where attackers embed malicious URLs or fake UPI payment links into QR codes. When scanned, these codes can redirect victims to fake websites designed to steal login credentials, financial data or even trick users into making unauthorized UPI payments. In some cases, scanning may also lead to malware downloads.

Quishing exploits the convenience of QR codes to redirect users to fake websites or trigger malicious actions. Attackers create QR codes that appear legitimate but are designed to steal data, spread malware, or commit fraud.

How Quishing Happens?

Attackers create a QR code that links to a malicious website. They place these QR codes on posters, emails, websites, or even physical locations like restaurants and public boards. When someone scans the QR code using their smartphone, it automatically opens a fake website designed to look real. The website may ask for login credentials, financial information, or download harmful software onto the device.

 

Fake QR Code Creation

Fraudsters stick their own QR codes over legitimate ones in places like stores, restaurants or donation counters. When scanned, your UPI payment goes directly to the hackers’s account, not the intended recipient.

Phishing Through QR Codes

The code leads to a fake login page that looks like a real one (e.g., bank, email, social media). You enter your credentials, which are sent to the scammer.

Malware Downloads

Scanning the QR code triggers the download of a malicious app or file. The malware can steal data, track activity or take control of your device.

How to Protect from Quishing

• Be cautious: Only scan QR codes from trusted sources. Avoid scanning random codes found in public places or emails from unknown senders.
• Verify the Source: Avoid scanning random or unverified QR codes, especially in public places or unsolicited messages.
• Preview the link: Many smartphones allow you to preview the URL before opening it. Check if the link looks suspicious or unfamiliar.
• Use a Secure Scanner App: Choose a QR scanner that shows the URL preview before opening the link.
• Use security software: Install antivirus and mobile security apps that can detect and block malicious websites.
• Enable multi-factor authentication: This adds an extra layer of security even if your login credentials are stolen.
• Stay updated: Keep your device’s operating system and apps updated to protect against known vulnerabilities.
• Avoid Sharing Sensitive Data: Never enter passwords or payment details after scanning a QR code unless you’re certain of its legitimacy.
