As a technology service provider, we are constantly keeping an eye on emerging cyber threats to help protect our clients. One of the latest threats that businesses need to be aware of is Quishing.
While phishing is a well-known term, quishing is a new and growing attack vector that specifically targets QR codes, taking advantage of the increased use of these codes in everyday business operations.
What is Quishing?
Quishing (QR-code phishing) is a type of phishing attack where hackers use malicious QR codes to trick users into giving away sensitive information or installing malware.
While QR codes are incredibly useful for tasks such as accessing websites, menus, and documents quickly, they can also be exploited by cybercriminals to direct users to malicious websites that look legitimate but are designed to steal data.
How Does Quishing Work?
The attack is deceptively simple:
- A cybercriminal generates a QR code that leads to a malicious site.
- They then replace legitimate QR codes (on emails, posters, flyers, or even in physical spaces like offices) with their fraudulent versions.
- When users scan the code with their mobile device, they are redirected to a phishing website designed to look authentic, often mimicking well-known services or login pages.
- Once users enter their login details, payment information, or other sensitive data, it’s captured by the attackers.
Because QR codes aren’t easily human-readable, it’s almost impossible to spot a malicious code just by looking at it, making this technique particularly dangerous.
Why is Quishing a Growing Concern?
With the rise of hybrid work models, increased use of mobile devices, and the widespread adoption of contactless solutions post-pandemic, QR codes have become more commonplace. As a result, cybercriminals are exploiting this shift, knowing that users tend to trust QR codes. For businesses and technology service providers, this threat is particularly concerning because:
- Staff may be less familiar with the risks of scanning QR codes compared to traditional phishing.
- BYOD (Bring Your Own Device) policies mean employees may be scanning QR codes on personal devices with fewer security protections.
- Cyber awareness training often focuses on email phishing, leaving gaps in employee understanding of newer threats like quishing.
How to Protect Against Quishing Attacks
While quishing is a relatively new threat, there are steps businesses can take to protect themselves and their clients:
- Educate employees – Make sure your staff are aware of the risks associated with QR codes and remind them to always verify the source before scanning.
- Use trusted QR code generators – If you’re using QR codes in your business, ensure they’re generated through secure, verified platforms.
- Implement URL previewing – Many mobile devices have settings or apps that allow users to preview a URL before visiting it. Encourage employees to use these tools to check for suspicious links.
- Cyber awareness training – Incorporate quishing and other emerging threats into your regular cybersecurity training. Make sure employees know that phishing doesn’t only occur through email.
- Adopt strong security policies – Limit the use of personal devices for business purposes, and ensure all devices accessing company data are equipped with security software to detect malicious activity.
- Stay updated – Partner with a trusted technology service provider to ensure your business is always up to date on the latest threats and has strong defenses in place.
As technology evolves, so do the tactics of cybercriminals. Quishing may be a relatively new threat, but it’s one that businesses should take seriously, especially in an environment where QR codes are becoming increasingly embedded in daily operations. By raising awareness and implementing robust security measures, your business can avoid falling victim to these sophisticated attacks.
