Overview of QR Analyzer

QR Analyzer is a specialized tool designed for the analysis and security assessment of QR codes, specifically focusing on the URLs they encode. At its core, QR Analyzer employs the Python cv2 library to decode QR codes, extracting the URLs embedded within them for further examination. The primary goal of QR Analyzer is to evaluate the potential security risks associated with these URLs. This involves checking if a URL imitates a well-known website's domain (indicating phishing attempts) or uses an uncommon top-level domain, which could suggest a moderate risk level. URLs are also sanitized for safety, with 'http' being replaced with 'hxxp'. Based on this analysis, QR Analyzer assigns a risk score ranging from 0 (indicating no risk) to 100 (indicating a high risk). This tool is crucial in a digital environment where QR codes are ubiquitously used for various purposes, from accessing menus in restaurants to logging into websites, making security a paramount concern.

Core Functions of QR Analyzer

  • Decoding QR Codes

    Example Example

    Extracting a URL from a QR code scanned at a café for a digital menu.

    Example Scenario

    A user scans a QR code to access a café's menu. QR Analyzer decodes the QR code to reveal the URL, allowing the user to understand the destination before visiting it.

  • Security Risk Assessment

    Example Example

    Identifying a URL that closely resembles a popular social media platform but is hosted on a suspicious domain.

    Example Scenario

    Upon decoding a QR code, QR Analyzer assesses the extracted URL and identifies it as high risk due to its resemblance to a popular social media site, but with a slightly altered domain name, indicating a potential phishing attempt.

  • URL Sanitization

    Example Example

    Converting 'http' to 'hxxp' in URLs to prevent accidental clicks on potentially harmful links.

    Example Scenario

    To enhance safety, QR Analyzer modifies the protocol of decoded URLs from 'http' to 'hxxp', ensuring that users do not inadvertently access dangerous sites.

  • Risk Scoring

    Example Example

    Assigning a score of 85 to a URL that mimics a banking website but has an uncommon top-level domain.

    Example Scenario

    After analyzing a URL encoded in a QR code, QR Analyzer assigns a high-risk score due to its deceptive similarity to a legitimate banking website combined with an uncommon top-level domain, signaling users to proceed with caution.

Target Users of QR Analyzer

    These individuals can use QR Analyzer to quickly evaluate the safety of QR codes encountered during security audits or investigations, enhancing their ability to protect organizational assets and sensitive information.
