Quishing: The New Cyber Threat You Need to Know About

If you are like most people, you probably scan QR codes on a regular basis. Whether it’s to check in at a restaurant, access a discount coupon, or get more information about a product, QR codes are everywhere. They are convenient, easy, and contactless. But they can also be dangerous.

QR codes are not just harmless black and white squares. They can hide malicious links or files that can compromise your security and privacy. This is called quishing, a form of phishing that uses QR codes to trick you into revealing sensitive information or downloading malware.

How Does Quishing Work?

Quishing works by exploiting your trust and curiosity. Cybercriminals create fake QR codes that look legitimate, such as ones that offer a free trial, a prize, or a donation. They then distribute these QR codes through various channels, such as emails, social media posts, flyers, posters, or stickers.

When you scan the QR code with your smartphone or other device, it redirects you to a fake website or file that is controlled by the attacker. The fake website may look like a familiar brand or service, and ask you to enter your personal or financial information, such as your name, email, password, credit card number, or bank account details. The fake file may be an app, a document, or an image that contains malware that can infect your device and steal your data.

What Are the Risks of Quishing?

Quishing can pose serious risks to both individuals and organizations. By scanning a malicious QR code, you may:

• Lose your money or identity: If you provide your financial information to a fake website, the attacker can use it to make fraudulent transactions or steal your identity. You may also lose access to your online accounts if you give away your login credentials.
• Damage your device or network: If you download malware from a fake file, the attacker can take control of your device or network and access your files, contacts, photos, messages, and other data. The malware may also encrypt your device or network and demand a ransom to restore it.
• Harm your reputation or relationships: If the attacker sends emails or messages from your account to your contacts, they may damage your reputation or relationships. The attacker may also use your account to spread more quishing scams to other people.

How to Protect Yourself from Quishing?

Quishing is not easy to detect, as the attackers create convincing websites and logos that mimic known brands. However, there are some steps you can take to protect yourself from quishing:

• Be cautious: Do not scan any QR codes that you do not fully trust or recognize. Avoid QR codes that are in public places, such as promotional posters, stickers, or adverts. Instead, look up the organization directly through a secure browser.
• Check the URL: Before entering any information on a website that you accessed through a QR code, check the URL carefully. Look for any spelling errors, unusual characters, or suspicious domains. If the URL does not match the expected brand or service, do not proceed.
• Use antivirus software: Install and update antivirus software on your device and network. This can help you detect and remove any malware that may have been downloaded from a fake file.
• Report any suspicious activity: If you encounter any quishing scams or fall victim to one, report it to the relevant authorities or organizations. This can help them take action and prevent further damage.

Quishing is a new cyber threat that you need to be aware of. By following these tips, you can stay safe and avoid falling for quishing scams. Remember: Think before you scan!
