The Growing Threat of QR Code Phishing
QR codes have become an everyday feature of transactions, providing one click access to websites, product pages, and social media accounts. But with this convenience, a new cybersecurity threat has emerged: quishing, or QR code phishing.
This criminal technique involves hackers embedding malicious URLs in QR codes to trick users into compromising their personal or company data.
Here’s a look at the ins and outs of quishing and how to use QRs safely.
Cracking the code: how hackers create fraudulent QRs
QR codes are all over the marketplace, from restaurant menus to payment systems, and even multi-factor authentication. However, their widespread use has also made them an appealing tool for attackers.
Unlike traditional phishing emails, quishing bypasses many email filters and firewalls because the malicious link is hidden within an image rather than plaintext. This makes it harder for legacy software to detect and block.
- A typical quishing attack usually involves a scammer placing a fake QR code sticker over a legitimate one. You may even find one on a parking meter, ATM, or restaurant table.
- When scanned, the QR code directs the victim to a fake website that looks legitimate, prompting them to log in, make a payment, or enter sensitive information.
- In the worst case scenario, the QR code might trigger the download of malware that compromises a user’s entire device.
Quishing is especially dangerous because of the high level of trust that users have when scanning a QR code. Many of us don’t double check QR codes the way we do suspicious links or attachments, opening the door to opportunistic attacks.
This complacency, combined with a lack of visual cues about where the QR code leads, increases the risk of falling for these scams which are becoming more prevalent across SA.
How to use QRs safely and avoid quishing
As cybersecurity experts, we recommend several best practices to reduce the chances of a quishing incident:
- Know Your QR. Always verify the source of a QR code before scanning it.
- Educate Employees. Raise awareness about the risks associated with scanning unknown QR codes, especially those received via email.
- Use Advanced Email Filtering: Email security solutions that can detect and block emails containing malicious QR codes are essential today.
- Make Secure QR Code Scanners Mandatory: Direct the use of QR code scanners in your office that can preview URLs before opening them, helping to identify potentially malicious links.
