How Scammers are stealing your information by QR code fraud: Scambusters #1,134
While QR codes offer ease and convenience, they also carry hidden risks.
In this week’s issue, Scambusters will tell you how scammers use QR codes to steal your information.
Let's get started…
The Hidden Dangers of QR Codes: What You Need to Know
QR (Quick Response) codes are two-dimensional barcodes that store data readable by smartphones and QR scanners. Initially, QR codes were used in the automotive industry to track parts during manufacturing, but now QR codes are used in advertising, purchasing tickets, completing online forms, and much more.
The codes can store various types of information, such as URLs, contact details, and text messages. When scanned, the data embedded in the QR code is quickly decoded and takes you to the website where you are looking for information.
Why the Popularity of QR Codes?
QR codes have become popular due to their user-friendly, easy access. The convenience of QR codes cannot be overstated. They connect the physical and digital worlds, allowing users to easily interact with online content through offline methods. For example, a QR code on a poster can instantly lead to a website or social media page, encouraging engagement.
Businesses use QR codes to streamline payment processes, reducing the need for physical cash or card transactions. A good example is using this process during a pandemic. QR codes can be dynamic, meaning they can be updated without changing the actual code, offering flexibility for marketing campaigns or promotions. Because QR codes make assessing so easy, people assume all QR codes are safe.
How Do QR Codes Become a Tool for Scammers?
Despite their benefits, QR codes come with imminent risks. The convenience that makes them appealing can also make them a target for scammers. Since scanning a QR code requires minimal effort, users can easily overlook potential security threats.
One of the main risks is the inability to see the embedded information before scanning. This lack of transparency can lead to malicious websites or phishing attempts. Furthermore, QR codes can be tampered with; scammers can easily cover legitimate QR codes with malicious ones without anyone noticing.
Another tactic involves sending QR codes via email or messaging apps, urging recipients to scan them for special offers or urgent notifications. The unsuspecting user might then be directed to a malicious site or prompted to download malware. These methods take advantage of the trust people place in QR codes.
Scammers' exploitation of QR codes hinges on their ability to disguise malicious intents. Since QR codes look identical to the naked eye, detecting a fake one can be challenging. This anonymity allows scammers to use QR codes as a tool for various fraudulent activities.
We know phishing attacks are one of the most common scams involving QR codes. When scanned, the code may direct users to a fake website that mimics a legitimate one. Here, users are prompted to enter sensitive information such as login credentials or credit card details, which scammers then will run wild with, causing the victim many problems.
Red Flags to Using Corrupted QR Codes
While QR codes themselves are neutral, certain red flags can indicate potential risks. One warning sign is a QR code placed on top of another, suggesting it may have been tampered with. Additionally, be cautious of QR codes in unsolicited messages or emails, especially if they promise something too good to be true.
Another red flag is the absence of any circumstances around the QR code. If a QR code appears randomly without any explanation or branding, it's best to avoid it. Always look for accompanying information that indicates who provided the QR code and what it’s meant for.
Businesses post QR codes about a special promotion or a “new” menu item and place them on a stand in front of their business. The scammer could easily place a fraudulent QR code over the legitimate code, hoping to catch another victim.
What Are Some Problems QR Codes Have Caused?
QR codes have led to several security issues, including data breaches and financial losses. In some cases, businesses have fallen victim to scams where fake QR codes direct customers to phishing sites, resulting in compromised payment information.
Instances of malware distribution through QR codes have also been reported. Scanning a malicious QR code can trigger the download of harmful software, compromising the device's security. These problems underscore the importance of exercising caution when interacting with QR codes.
How Can I Protect Myself from Being Scammed by QR Codes?
- Use a reliable QR code scanner app to detect malicious links. Some apps offer features that preview the URL before opening it, allowing you to verify its legitimacy.
- Avoid scanning QR codes from unfamiliar sources. Trustworthy QR codes are usually accompanied by information or branding that indicates their origin. If in doubt, manually entering the URL is a safer alternative than scanning an unknown QR code.
- Always inspect the QR code for signs of tampering, such as stickers placed over the original code. Be wary of QR codes in unsolicited communications and verify the source before scanning.
- Consider using security software that scans for and blocks malicious websites. Many antivirus programs offer features that can protect against threats posed by QR codes.
