What is Quishing - or QR-code Phishing?
Have you heard the term quishing? It's the latest tactic cybercriminals are using, and it has evolved with the popularity of QR codes. We all use QR codes because they are a convenient way to access information or pay for things, but unfortunately, there’s a new risk attached to their convenience.
Unlike traditional phishing emails that include unsafe text links, QR code phishing hides the threat behind a simple black-and-white image that feels completely harmless. Understanding this shift can help you make informed decisions and keep your business operating smoothly.
This guide will clearly explain what 'quishing' is, how these codes are being manipulated, and outline practical steps that can safeguard yourself and your business.
Understanding QR Phishing and why it's a growing concern
Quishing, or QR code phishing, refers to the use of QR codes to direct people to websites or prompts they didn’t intend to access, such as login pages or software downloads. It typically involves placing a misleading link within a QR code found in emails, posters, or digital ads. The approach relies on simple tactics that encourage people to scan without realising the destination isn’t what they expected.
Quishing is on the rise because QR codes are now part of our daily routine, and criminals are taking advantage of that trust.
How it works:
Fake QR codes: Cybercriminals might place fake QR code stickers over legitimate ones. This can happen in public places like parking meters or restaurant menus, or it can be delivered right to you through emails and unsolicited packages.
Phishing websites: When you scan a fake code, it takes you to a fraudulent website that looks completely real. This site is designed to steal your login credentials, credit card numbers, or other sensitive personal information.
Deceptive scenarios: The codes often rely on social engineering to work quickly. For instance, a fraudulent email might use a QR code to "verify" an account, or a code on a package might prompt you to pay a small fee to avoid a penalty.
The key to protection is understanding that the convenience of the code is being misused. By knowing the tactics, your business is already better prepared to handle them.
What are the dangers of ‘quishing’?
Understanding the potential outcomes of a quishing attack is important so you can proactively protect your business. The risks fall into two categories:
Risks for Individuals:
For your employees, a successful phishing attack can lead to personal information being leaked. Attackers aim to commit financial fraud by stealing credit card numbers or bank information, or to achieve identity theft by using stolen personal data. It can also compromise online accounts, including email, or install malicious software like ransomware, which locks files until a ransom is demanded.
Risks for Businesses:
Data breaches: Even a single compromised account can provide access to parts of a company’s network, highlighting the importance of strong security practices to protect sensitive customer and employee information.
Reputational damage:Mismanaged customer or employee data can affect trust in your company, making it important to handle information carefully and maintain strong data practices.
Operational Disruption: Malware such as ransomware can disrupt business operations, making sensitive files inaccessible and leading to costly system downtime and recovery efforts.
What are the warning signs of quishing?
The best defence is knowing what to look for. By taking just a moment to pause and check, you can avoid all quishing attempts. Here are the warning signs to keep in mind:
Check the Source
Unsolicited messages: Be cautious of QR codes you receive through unexpected emails, texts, or flyers. If you weren't expecting it, treat it as suspicious.
Physical tampering: In public places (like parking meters), check closely to see if a sticker or overlay has covered a legitimate code.
Urgent language: Scams rely on high-pressure tactics. If the message uses phrases like "urgent action required" or "your account will be locked" to force a quick scan, it’s a telltale sign that something's not right.
Check the Destination
Suspicious URLs: After scanning, quickly check the URL. If it looks misspelled, shortened, or doesn't clearly match the supposed company's domain, do not proceed.
Unusual requests: Legitimate QR codes will not ask you for sensitive data like login details, full credit card numbers, or passwords immediately after scanning.
Unexpected prompts: A legitimate code should not ask you to grant unusual device permissions (like camera or location access) or prompt you to download a new app or file. If your phone asks to download something, close the browser immediately.
