Internship Experience

Real-world experience across law enforcement digital crime investigations and technical cybersecurity research.

Cyber Crime Intern

06/2025 – 07/2025
Puducherry Cyber Crime Police Station
  • Registered and documented cybercrime complaints systematically, ensuring accurate case intake, evidence chain of custody, and record-keeping.
  • Supported official investigation into a social media-based hardware scam case involving fraudulent advertisements targeting local shop owners for financial fraud.
  • Gained practical knowledge of the end-to-end cybercrime case lifecycle from complaint registration and digital footprint analysis to investigation and resolution.

Cybersecurity Intern

12/2025 – 01/2026
Elevate Labs
  • Gained hands-on experience with industry-standard security tools including OpenVAS, Wireshark, and Nmap for network vulnerability scanning and packet traffic analysis.
  • Built a Password Strength Checker tool in Python to evaluate password security and entropy based on complexity, dictionary attacks, and NIST best practices.
  • Developed a Web Vulnerability Finder tool to audit and identify common security flaws and OWASP weaknesses in target web applications.

Featured Projects

Real security platforms, monitoring frameworks, and automated scanning utilities designed and built from scratch.

Web Vulnerability Scanner

Automated security scanning script designed to analyze target web endpoints, audit HTTP headers, inspect inputs, and identify common vulnerabilities (such as cross-site scripting risks and information leaks).

Python Vulnerability Audit OWASP Top 10 HTTP Analysis

Password Strength Checker

Security utility built to test and quantify password resilience against brute-force and dictionary attacks. Calculates information entropy and evaluates passwords based on NIST security guidelines and complexity best practices.
