QR codes have become part of everyday life. People use them to view restaurant menus, pay for parking, download apps, or visit websites. With a quick scan from a smartphone camera, these codes connect users directly to online information. Their convenience has made them extremely popular in both personal and professional settings.
However, the same technology that makes QR codes useful has also opened the door for cybercriminals. A new type of scam, known as “quishing,” is now targeting unsuspecting users. The term combines “QR” and “phishing” and refers to scams where fake QR codes are used to deceive people. These codes often lead to fraudulent websites, steal personal information, or install malicious software on users’ devices.
One of the main problems with QR codes is that users cannot see the website or destination behind the code before scanning it. This invisibility gives scammers an opportunity to hide harmful links inside what appears to be a harmless image. In many cases, people scan QR codes without thinking twice, assuming they are legitimate simply because they appear in trusted locations.
Criminals have found various ways to exploit this. In public places, they may place stickers with fake QR codes over the original ones. A person trying to pay for parking or access a service might scan the code, thinking it belongs to the business, and instead end up on a fake website designed to collect sensitive data. The person may unknowingly provide credit card numbers, login credentials, or other personal information that falls straight into the hands of the scammers.
The danger is not limited to public signs. Fake QR codes also appear in text messages, emails, or social media posts. These messages may claim to be from delivery services, banks, or online stores, asking users to confirm a transaction or verify an account. Once scanned, the QR code may direct the user to a convincing-looking webpage that prompts them to enter personal information. Sometimes, scanning the code can even trigger a download of harmful software that compromises the user’s device and data.
These attacks are effective because of the trust people place in QR codes. They’re used so often and appear in so many normal, safe settings that people rarely question them. Unlike links in emails, which many users have learned to approach with caution, QR codes are still seen as secure by default. This assumption is what makes quishing such a powerful trick.
Several events have shown the potential harm caused by these scams. In one instance, patrons at a cafe believed they were accessing the menu via a QR code, only to be directed to a website that harvested their social media credentials. In a different scenario, counterfeit QR code labels on public parking meters tricked individuals into entering their card information on a fraudulent payment platform. These schemes can lead to not just monetary damage but also identity theft and unauthorized entry into personal or corporate accounts.
The growth of quishing is tied to how QR codes became more common during the COVID-19 pandemic. As businesses sought contactless ways to share information or receive payments, QR codes offered a fast solution. Unfortunately, this widespread use also gave scammers more opportunities to imitate legitimate services. As QR codes continue to be part of daily life, it’s expected that quishing tactics will become more advanced.
Many people are unaware that their devices may already be at risk after scanning a malicious code. Malware can run silently in the background, logging keystrokes, recording passwords, or even gaining access to the phone’s camera and microphone. The impact of one quick scan can be long-lasting and difficult to trace back to its source.
For the average user, the best way to avoid becoming a victim is to be cautious. Although QR codes are helpful, it’s important to stop and think before scanning. If the code comes from a flyer, email, or message that wasn’t expected or seems suspicious, it’s safer not to engage with it. Being able to recognize signs of a fake QR code, such as a sticker placed over another code or poorly designed materials, can also help prevent a scam from succeeding.
The battle against quishing also relies on the manner in which companies handle their utilization of QR codes. Companies should frequently check their codes to confirm they haven’t been altered. They may also implement additional measures like using QR codes with custom branding that are more difficult to imitate or offering verification steps to provide users with extra confidence that the page they have accessed is authentic.
Despite efforts to educate the public and improve safety features, it’s clear that quishing is a growing concern. Its success depends on speed and simplicity. Scammers count on people reacting quickly—scanning without thinking, entering details without double-checking, and trusting that the process is secure. Awareness is the first line of defense. People need to be reminded that QR codes, like email links, are not always safe just because they’re convenient.
Technology companies are beginning to explore ways to improve QR code safety. Some solutions include adding visual cues to codes to confirm authenticity, requiring users to confirm links before opening them, or even developing smarter apps that scan the destination of the QR code before it is opened. These are promising steps, but for now, users must rely on good habits and awareness.
Phishing schemes have demonstrated that even the simplest instruments can be used against us when misused. As cyber attackers grow more inventive, users must also adapt. Prudence, analytical thinking, and vigilance remain the most reliable methods for remaining secure in a digital environment where even a basic scan can be dangerous.
