Browser Cookie Analyzer
Security & Privacy Inspection for Browser Cookies
Overview
Browser Cookie Analyzer is a security-focused tool for inspecting and evaluating browser cookies in web applications. It categorizes cookies by security attributes (HttpOnly, Secure, SameSite), identifies potential vulnerabilities like session hijacking risks or missing security flags, and generates a comprehensive security report. Designed for developers, penetration testers, and security auditors who need quick, actionable cookie security assessments during web application security reviews.
🔴 The Problem
Cookie misconfigurations are one of the most common web vulnerabilities — missing HttpOnly, Secure, or SameSite flags expose users to XSS, CSRF, and session hijacking attacks. Manually checking every cookie in a large application is tedious and error-prone.
🟢 The Solution
Cookie Analyzer automates the security inspection process — paste a cookie string or connect to a target URL, and the tool immediately identifies all security issues, explains each vulnerability, and provides remediation guidance with code examples.
Architecture
Single-page web application with a JavaScript parsing engine. Cookie strings are parsed and analyzed client-side using a rule-based security engine. Results are categorized by severity (Critical, High, Medium, Low) and displayed in a clean dashboard. Export functionality generates PDF or JSON security reports.
Challenges
Accurately parsing non-standard cookie formats from diverse web frameworks
Distinguishing between intentional design decisions and actual security flaws (context-aware analysis)
Building a rule engine that stays current with evolving cookie security standards (RFC 6265bis)
Results
Correctly identified all major cookie security issues in OWASP WebGoat test application
Used during Supraja Technologies internship for web application security assessments
Covers 15+ distinct cookie security checks across OWASP and RFC standards
Lessons Learned
Security tools live or die by their false positive rate — precision matters more than recall
Good security reporting explains the risk and the fix, not just the finding
