Quishing (Qr Phishing)
What is Quishing (QR Phishing)?
Quishing, or QR phishing, uses malicious QR codes to direct users to fraudulent sites or downloads.
Attackers replace trusted codes or embed fake ones to steal credentials, payment data, or install malware.
Analyzing Quishing
Why It Works So Easily
QR symbols feel routine in restaurants, transit hubs, parking meters, and advertisements, so people often scan reflexively. That habitual behavior reduces scrutiny and gives social engineering a convenient delivery mechanism.
Unlike typed links, encoded destinations stay hidden until after scanning. That obscurity weakens common safety checks, especially on mobile devices where previews, browser indicators, and security cues appear limited initially.
The Power of Context
These campaigns succeed by exploiting context, not just technology. A code beside a payment terminal, event poster, or office notice inherits credibility from its surroundings and suppresses skepticism for many.
Timing also matters. Urgent prompts like expiring discounts, failed deliveries, or account verification requests pressure users into quick scans before they evaluate legitimacy, source ownership, or expected outcomes carefully first.
Why Detection Is Harder
Organizations face a visibility problem because physical placements and printed materials fall outside many traditional email defenses. Security teams may detect the aftermath, while the initial lure remains unnoticed longer.
Mobile-first interactions worsen exposure. Employees and customers frequently use personal phones, creating gaps in monitoring, patching, and response workflows. That fragmentation complicates investigation, containment, notification, and recovery after incidents significantly.
How Risk Can Be Reduced
Effective mitigation combines design, process, and education. Encourage destination previews, direct app access instead of scans, and rapid reporting channels for suspicious codes found in physical environments by staff members.
Longer term, resilience improves when organizations audit public-facing code placements, authenticate printed materials, and rehearse incident response. Reducing blind trust matters more than treating scans as harmless shortcuts every day.
Common Quishing Use Cases
Malicious ATM and Branch QR Codes
Attackers place malicious QR stickers on ATMs, branch posters, or mailed statements, redirecting customers to fake payment, card-update, or credential-capture pages. Compliance teams should monitor physical channels closely, customer complaints, and payment anomalies that indicate socially engineered QR-driven fraud campaigns.
Marketplace Seller and Payout Fraud
Fraudsters embed QR codes in seller onboarding emails, invoices, or shipment disputes, sending merchants to counterfeit portals that harvest credentials or trigger unauthorized payouts. Compliance officers should review QR-linked communications, payout changes, and account-verification exceptions across marketplace operations, daily patterns.
Ecommerce Account Takeover and Refund Abuse
Quishing campaigns imitate password-reset or guest-checkout flows, using QR codes on fake delivery notices or promotional inserts to capture customer logins and one-time codes. Compliance teams should correlate QR-themed phishing reports with account takeovers, refund abuse, and unusual device fingerprints.
Fake SSO Enrollment and Vendor Portal Access
Attackers use QR codes in fake security alerts, SSO enrollment pages, or vendor portal notices, pushing employees toward phishing sites that steal credentials or session tokens. Compliance officers should examine access logs, impossible travel, and anomalous actions following QR exposure.
Quishing Statistics
QR code phishing attacks increased by 400% between 2023 and 2025, with an average of 2.7 million emails containing QR codes detected daily and over 1.7 million unique malicious QR codes found in email attachments between October 2024 and March 2025. Source
Quishing incidents grew 5x (from 46,000 to 250,000 cases) between August and November 2025 alone, accounting for 12% of all phishing attacks, while Mimecast detected 655,673 unique malicious QR codes in Q4 2025 (down 9% from Q3). Source Source

Quishing (QR Phishing) FAQ
1. What is quishing?
Quishing is a type of phishing attack that uses QR codes instead of regular links. When someone scans the code, it may send them to a fake website, a malicious download, or a page designed to steal personal information.
2. How does quishing work?
Attackers create a QR code that leads to a harmful destination. They may place it in emails, text messages, posters, parking meters, restaurant menus, or fake invoices. Because the real link is hidden inside the QR code, people may trust it more than a suspicious-looking URL.
3. Why do scammers use QR codes?
Scammers use QR codes because they are easy to scan and often look harmless. Many users also check less carefully before scanning a code than before clicking a link, which makes QR codes a useful tool for phishing attacks.
4. What are common signs of a quishing attack?
Some warning signs include:
A QR code in an unexpected email or message
Pressure to act quickly, such as “scan now” or “urgent payment required”
A QR code placed over another code on a public sign
A website opened after scanning that asks for passwords, payment details, or MFA codes
Poor grammar, strange branding, or unusual requests
5. Where might I encounter quishing?
Quishing can appear in many places, including:
Emails pretending to be from banks, delivery companies, or IT support
Text messages about missed packages or account problems
Printed flyers, posters, or stickers in public places
Fake payment stations, parking meters, or restaurant tables
Social media posts and online ads
6. What should I do before scanning a QR code?
Before scanning, check where the code came from and whether you trust the source. If the code is on a public sign, look for signs it may have been covered by a sticker. If your phone shows a preview of the link, read it carefully before opening it. When possible, go directly to the official website instead of using the QR code.
7. What should I do if I think I scanned a malicious QR code?
If you scanned a suspicious code:
Do not enter any passwords or payment information
Close the website immediately
Run a security scan on your device if you downloaded anything
Change your password if you entered login details
Contact your bank or service provider if financial information was shared
Report the incident to your IT team or the affected company
8. How can I protect myself from quishing attacks?
You can reduce your risk by:
Scanning QR codes only from trusted sources
Previewing links before opening them
Using multi-factor authentication
Keeping your phone and apps updated
Avoiding downloads from unknown QR codes
Verifying requests through official channels
Using mobile security tools when available
