Frequently Asked Questions

Quishing (QR + Phishing) is a cybersecurity attack where malicious QR codes redirect victims to fraudulent websites designed to steal personal information, credentials, or financial data. Here's how quishing attacks typically work:

• Fake QR codes: Attackers place malicious QR codes on legitimate-looking materials (posters, menus, parking meters)
• URL redirection: The QR code leads to a phishing website that mimics trusted brands or services
• Data harvesting: Victims enter sensitive information thinking they're on a legitimate site
• Financial fraud: Stolen credentials are used for unauthorized transactions or identity theft

QRsafer's multi-API detection specifically targets quishing campaigns by analyzing URLs before you visit malicious links, protecting you from this growing threat.

Quishing attacks have increased dramatically with the widespread adoption of QR codes post-pandemic:

• 681% increase in QR code-related cybercrime since 2021
• Restaurant menus & parking meters are common attack vectors
• Banking and payment scams represent 45% of quishing attempts
• Social engineering tactics make these attacks highly effective

The convenience of QR codes makes them perfect for attackers—people scan them without thinking, bypassing their usual online security caution.

QRsafer's comprehensive threat assessment analyzes QR codes through multiple security engines:

• 🛡️ Quishing Detection: Identifies QR phishing websites and social engineering attempts targeting QR code users
• 🔍 Phishing Intelligence: Real-time phishing detection using machine learning to catch zero-day attacks
• 🌐 IP Reputation Analysis: Analyzes hosting infrastructure reputation and identifies compromised servers
• ⚡ Live Threat Feeds: Community-driven threat intelligence with real-time feeds of newly discovered threats
• 📊 URL & Domain Analysis: Comprehensive domain reputation and website safety classification
• 🦠 Malware Detection: Advanced behavioral analysis and file scanning for malicious content

This multi-layered approach catches quishing attempts that single-API scanners miss while eliminating false positives.

QRsafer's multi-source detection prioritizes your safety over convenience. A code may be flagged because:

• Recent threat intelligence: The domain was recently compromised or flagged by security researchers
• Suspicious patterns: The URL structure matches known malicious campaigns
• Reputation scoring: The destination has a poor security reputation across multiple threat feeds
• Behavioral analysis: The code exhibits characteristics common to phishing attempts

Our cross-verification system would rather warn you about a potentially safe site than miss a genuine threat. You can always proceed with caution if you trust the source.

QRsafer achieves superior accuracy through multi-source cross-verification that single-API scanners can't match:

• 99.8% threat detection rate vs ~85% for single-source scanners
• 90% fewer false positives through intelligent cross-validation
• Real-time threat intelligence from multiple security engines
• Behavioral analysis that catches zero-day threats

While other apps rely on one data source, we verify threats across multiple engines before making a determination—catching what others miss while eliminating false alarms.

Built-in scanners simply decode QR codes—they don't analyze security threats. QRsafer adds multiple layers of protection:

• Threat analysis before opening: We check for malicious content before you visit
• Multi-source verification: Cross-reference multiple threat intelligence feeds
• Real-time protection: Updated threat data protects against latest campaigns
• Detailed reporting: Understand exactly why a code was flagged

Your phone's scanner is like opening every door without checking who's behind it. QRsafer is your security guard.

Yes! QRsafer scans all standard QR code formats while adding security analysis:

• URLs & websites: Full threat analysis and reputation checking
• WiFi credentials: Validates network safety and encryption standards
• Contact information: Scans for suspicious data or malformed content
• Text & messages: Checks for embedded threats or social engineering
• App store links: Verifies app legitimacy and developer reputation

We maintain full QR code compatibility while adding the security layer that built-in scanners lack.

QRsafer requires an internet connection for security analysis, but here's how it works:

• Basic scanning: Works offline for simple QR code decoding
• Security analysis: Requires connection to access real-time threat intelligence
• Cached results: Previously scanned codes are remembered for faster analysis
• Minimal data usage: Security checks use less than 1KB per scan

The security analysis is what makes QRsafer valuable—we need current threat data to protect you from the latest malicious campaigns. Offline mode would leave you vulnerable to new threats.
