Once seen as a fading trend, QR codes made a major comeback during the COVID-19 pandemic for the purpose of accessing menus without contact, touch-free payments, and easier access to apps and services. But as its re-adoption increased, so did the attention from cybercriminals. Now in 2025, QR code scams are resurging, with scammers using them to bypass traditional security barriers and trick users into handing over personal data, login credentials, or even money.
These attacks are simple to execute, difficult to detect, and increasingly common in both consumer and business environments.
How QR Code Scams Work
At a glance, QR codes appear harmless. They’re just black-and-white squares directing you to a website or other digital resource. But beneath that simplicity lies a major vulnerability: humans can’t interpret QR codes visually, which means users don’t know where a code leads until it’s too late.
Scammers exploit this by creating malicious QR codes that redirect to phishing sites, fake payment portals, or malware downloads. These QR codes are then placed over legitimate codes in public places like restaurants, parking meters, or retail stores. They can also be embedded in phishing emails, scam flyers or packages from unknown senders to lure in victims.
Some attackers even send emails impersonating a trusted service and claim you need to scan the QR code to access a secure document, pay a fee, or confirm your identity. Instead, the QR code leads to a spoofed website that harvests credentials or installs malware.
Why QR Code Scams Are Effective
QR code scams are effective because they bypass many standard email and website security filters. A malicious link hidden behind a QR code isn’t clickable in the traditional sense, so system scanners and firewalls are less likely to detect it as a threat.
This technique also takes advantage of mobile device usage. Many people scan QR codes with their phones, which often lack the same endpoint protections as corporate desktops or managed workstations. And because the process feels convenient, users are less likely to pause and verify if the code is coming from a legitimate source before taking action.
Additionally, malicious QR codes account for 2% of all QR codes scanned in 2025.
Real-World Examples of QR Code Attacks
Law enforcement and cybersecurity agencies have tracked a surge in these scams over the past few years. In several major cities, attackers have placed fraudulent QR codes on parking meters and ticket machines, leading users to fake payment sites that harvest credit card details.
In another case, businesses were targeted through phishing emails with QR codes that impersonated Microsoft login portals. Employees were tricked into entering their credentials, resulting in compromised accounts and unauthorized access to internal systems.
These examples highlight how QR code scams can target both individuals and enterprises, exploiting gaps in physical and digital security.
How to Spot a QR Code Scam
Detecting a fraudulent QR code isn’t always easy, but there are warning signs to look for:
- Unfamiliar or suspicious context: Be cautious if you’re asked to scan a QR code unexpectedly, especially in emails, texts, or printouts you weren’t anticipating.
- Physical signs of tampering: Check for stickers or overlays placed on top of legitimate QR codes in public areas.
- Urgent or high-pressure language: Scams often try to create urgency or fear using language like: “scan now to avoid a fine” or fear “your account will be locked”.
- Generic destinations: Before clicking, preview the URL that appears after scanning. If it’s a shortened, misspelled, or unfamiliar link, don’t proceed.
Best Practices to Avoid QR Code Scams
Protecting yourself and your organization from QR code scams involves a mix of awareness, tools, and policies:
- Avoid scanning unfamiliar QR codes
Treat QR codes like clickable links, don’t scan them unless you trust the source. If something feels off, skip it. - Preview links before opening
Most camera apps display a URL before navigating. Verify the link looks legitimate, uses HTTPS, and matches the expected domain. - Use a QR code scanner with security features
Consider apps that include phishing and malware detection to add another layer of protection. - Educate employees and end-users
Include QR code scams in your security awareness training. Many users still don’t realize these attacks exist. - Inspect public-facing QR codes regularly
If your business posts QR codes for customer use (e.g., menus or payment portals), regularly check that they haven’t been tampered with. - Keep your device software up to date
Regularly update your phone’s operating system to patch known vulnerabilities. Outdated systems are prime targets for QR code scams and other mobile-based threats.
What to Do If You Scanned a Malicious QR Code
If you think you’ve fallen for a QR code scam, taking immediate steps can help minimize damage:
- Disconnect from Wi-Fi or mobile data to stop further communication with the attacker.
- Run a security scan using a trusted mobile antivirus app.
- Change any passwords entered after scanning the code, especially for financial or work accounts.
- Alert your IT/security team so they can assess potential impact on the organization.
- Report the incident to relevant authorities or platforms if financial or identity theft is involved.
