What is Quishing? How does it work and how to protect yourself

Quishing - What it is and how to protect yourself
Explanation of Quishing – how this phishing technique works via QR codes and what steps you can take to protect yourself.

Nowadays, QR codes are everywhere - from restaurant menus to in-store checkouts. However, scammers have found a new and very dangerous way to trick us through these codes. This modern scam is called Quishing and can steal your personal data in just a few seconds!

🤔 What Exactly Is Quishing?

The word Quishing comes from the combination of the words "QR" (the familiar square codes) and "Phishing" (electronic fraud). Simply put, scammers create fake QR codes that are intended to trick us into visiting dangerous websites or installing malicious programs on our device.

⚠️ Important Statistics!
According to the latest data for the years 2024-2025, 35% of misleading messages now contain QR codes, instead of traditional links!

🎯 How This Scam Works

Fraudsters exploit our trust and the fact that we are used to scanning QR codes without giving it much thought. They create codes that seem perfectly legitimate and harmless, but in reality lead to traps. The main problem is that, unlike a regular link where we can see the address before opening it, we cannot know where a QR code will take us before scanning it.

🚨 The Main Points to Watch Out For

(I.e.

Fake Codes in Public Places

They stick their own stickers with malicious codes over the official QR codes in places like restaurants, ATM machines, transport stops and other public spaces.

📧

Emails with QR Codes

You receive suspicious emails or messages that, instead of containing links, ask you to scan a QR code, often to bypass security systems.

(I.e.

Fake Websites

After you scan the code, a website opens that looks very similar to the real website of your bank, social networks, or other well-known services, with the aim of stealing your information.

🔍

Invisible Destination

There is no easy way to see the true URL hidden behind the code before visiting, which increases the risk.

🛡️

Difficult to Detect by Antivirals

Antivirus programs may not immediately recognize the danger, as the QR code itself does not contain malicious code, it simply leads to a dangerous point.

Immediate Impact

The damage can occur as soon as you visit the website or download the file, without any further action being required from you.

⚖️ Why Do Fraudsters Choose Quishing?

✅ What is Good for Them?

They Look Innocent: QR codes are common and do not arouse suspicion.
Bypass Filters: Email security systems have difficulty detecting a threat within a QR image.
Obsessed with Routine: Most people automatically scan codes without hesitation.
Easy Distribution: They can be easily placed in public places or sent en masse.

❌ What Doesn't Work for Them

Requires Physical Presence: To stick fake codes, they must be physically present in a space, which poses a risk for them.
The world is informed: More and more people are becoming more cautious and learning about these scams.
There are Protection Applications: Applications are being developed that help confirm the security of a QR code before scanning.

🛡️ How Can You Protect Yourself?

1
🔍 Check Destination Before Accessing

Use a QR scanning app that shows you the URL before you open the link. Many mobile phone apps now have this option. If the address looks suspicious (e.g., it has random letters or doesn't match the service you're expecting), don't open it.

2
🚫 Be Wary of Unknown Sources

Avoid scanning QR codes from street posters, unknown flyers, or unexpected emails. If the source is not trustworthy, the risk is high.

3
🔎 You are looking for Stickers

Before scanning a QR code in a public place (e.g., at a bus stop or at a payment machine), check carefully whether a fake sticker has been pasted over the original, legitimate code.

4
📱 Use Security Software

Install a reliable security program on your mobile phone that can warn you about suspicious websites and block access to them.

5
🔐 Be careful with personal information

Never enter usernames, passwords, credit card numbers, or any other sensitive data on a website you were directed to via a QR code unless you are absolutely sure of its authenticity.

6
🤔 Apply Common Sense

If an offer seems too good to be true (e.g., "You've won a large sum of money!"), it's almost always a scam. Always keep in mind that a free gift is very rare.

🚨 Recent Fraud Cases (2024-2025)

📄 Fake PDF Documents

Receiving emails claiming to contain urgent documents (such as invoices or calls) in PDF format, which however contain malicious QR codes.

🏧 ATM Fraud

Placing fake stickers with QR codes on or next to ATM machines, promising assistance with transactions or "updated instructions".

🍕 Fake Digital Menus

In restaurants, scammers are replacing real QR codes on digital menus with their own, which lead customers to fake payment pages.

📱 Fake App Updates

QR codes that appear in messages or web pages and claim to be for downloading "critical updates" for popular apps, such as banking apps.

🎯 Our Final Conclusion

The Quishing is a real and growing threat. The best defense against it is constant information, vigilance and a healthy dose of suspicion.

Remember this: Before scanning any QR code, pause and ask yourself: Where is this code located? Were you expecting it? Does it look legitimate and placed by a trusted source?

Share this information with friends and family. The more people are aware of the risk, the harder it becomes for scammers to achieve their goals!
