How Hackers Can Hijack Digital Signage: Scambusters #1,198
Imagine you're at a concert, conference, or halftime show, and you see a bright QR code on the screen offering “Free Merch” or “Exclusive Access.” You scan it without realizing the link may not be safe. In moments, a cybercriminal could steal your personal information. As more events use digital tools, scammers find ways to trick large crowds. Here’s how to spot these traps before they catch you.
QR Code Scams at Public Events: The Hidden Threat on the Big Screen
In previous Scambusters articles, I wrote about QR codes in public places, such as accessing menus from signage outside restaurants. In this issue, I want to increase our education on large-venue QR codes.
We see QR codes everywhere, like on stadium screens, concert halls, and at festival booths. These codes can give you special content or discounts or let you participate in an interactive activity during a sporting event timeout. They are easy to use, allowing many fans to connect with a brand or service quickly by scanning with their phone. However, as the use of QR codes has increased, so have the risks that come with them.
Scammers are targeting public QR codes at large events. They take advantage of the fast-paced and exciting atmosphere to trick attendees into giving away their personal and financial information. This guide explains the security risks of public QR codes, how these scams operate, and what steps you can take to protect yourself.
What Are the Risks of Public QR Codes?
When you scan a QR code at a concert, sporting event, or festival, you expect it to lead you to a real website. However, security experts have noticed more fake QR codes in public places. This scam is called "quishing" (QR code phishing). It involves replacing a real QR code with a fake one that takes users to a harmful site.
When you visit a fake website, you might be asked to provide sensitive information like your login details, credit card numbers, or personal information. Sometimes, scanning a QR code can download malware to your device without you realizing it. This malware can track what you do, steal your information, or even give a scammer access to your phone.
Have QR Code Scams Been Reported at Large Venues?
Yes, there have been QR code scams at big events. Scammers take advantage of the trust people have in official displays. They can easily stick a harmful QR code over a real one on a poster or table tent.
Scammers can also target digital screens, like Jumbotrons. Skilled hackers can use tricks to swap the official QR code for their own, even if security measures are in place. They might deceive an employee or find a weakness in the venue's network. Venue operators know about this threat and are working to improve their digital security, but the risk is still there.
How Do These Scams Unfold?
Scammers choose their locations for placing harmful QR codes carefully. They often target large venues where many people gather. The crowd is usually distracted and excited, which makes them act quickly without thinking. A QR code that promises a free drink, a discount on merchandise, or a chance to win tickets can be very tempting.
Here are some of the most common scams linked to fraudulent QR codes:
- Phishing Scams – The QR code takes you to a fake website that looks like a real brand, such as a venue, a sponsor, or a food vendor. It asks for your login or payment information, which scammers then steal.
- Malware Downloads – Scanning the code will automatically download harmful software. This software could be spyware that tracks what you do or ransomware that locks your device until you pay a fee.
- Payment Redirection – You think you are buying parking, merchandise, or a drink, but the QR code sends your payment to a scammer's account instead.
Can Your Identity Be Stolen?
Identity theft is a real danger with QR code scams. If a fake website tricks you into sharing personal information like your name, address, date of birth, or Social Security number, a scammer can use that information to open accounts in your name or commit other types of fraud.
If you only enter your email and password, scammers might use that information to try to access your other online accounts if you have the same passwords. If they succeed, they can lock you out and steal more of your personal information.
A Real-World Example
Scammers are putting fake QR code stickers on parking meters in different cities. When people scan these codes, they get taken to a convincing but fake website to pay for parking. Instead of paying the city, they end up sending money directly to the criminals and sharing their credit card details. This trick can also happen at big concerts or sports events where people pay for parking.
What to Do If You Suspect a Scam
If you scan a QR code at a large venue and something feels off, act immediately.
- Disconnect from Wi-Fi – If you are connected to the venue’s public Wi-Fi, disconnect immediately to prevent further data transmission.
- Do Not Enter Information – If the website looks suspicious or asks for more information than seems necessary, close the browser tab. Do not enter any login credentials, personal data, or payment details.
- Clear Your Browser Data – Delete your browser's cache and cookies to remove any traces of the malicious site.
- Run a Security Scan – Use a reputable antivirus or anti-malware app on your phone to scan for any malicious software that may have been downloaded.
- Change Your Passwords – If you entered a password on the suspicious site, change it immediately on all other accounts where you use the same or a similar password.
- Monitor Your Accounts – Keep a close eye on your bank and credit card statements for any unauthorized charges. If you find any, report them to your financial institution right away.
Where to Find Help
If you believe you have fallen victim to a QR code scam, you can report the incident to the following organizations:
- The Federal Trade Commission (FTC)
- The FBI's Internet Crime Complaint Center (IC3)
- Your Local Police Department – File a report, especially if you have lost money or believe your identity has been stolen.

Stay Alert and Scan Safely
QR codes are very handy, especially in busy places like stadiums and concert halls. However, they come with risks that everyone should be aware of. Scammers target these events and use simple tricks to steal money and personal information.
To protect yourself, be careful and look for warning signs. Always think before you scan. Check for any signs of tampering and don’t trust offers that seem too good to be true. Never enter sensitive information on a site accessed through a public QR code without first verifying if it is legitimate. A few moments of caution can help you avoid the trouble of fraud.
Remember, Stay Alert and Stay Informed!
