I'm Dayanidhi Meganathan, an MSc Cybersecurity student who has worked live cybercrime cases with the Tamil Nadu Police Cyber Cell and now builds open-source security tooling and DFIR workflows.
I'm currently reading for an MSc Cybersecurity with Work Placement at the University of Hertfordshire, after a BCA in Cybersecurity from BSA Crescent Institute in Chennai (CGPA 8.13/10).
My work sits across three areas: digital forensics & incident response, offensive security (vulnerability assessment, CTFs, bug bounty style testing), and practical tool-building — turning a security problem into something I can ship, measure, and hand to someone else to use.
I got my start in the field on live cases, not lab exercises — three months investigating real reports at the Tamil Nadu Police Cyber Cell shaped how I think about evidence and risk ever since.
Supported live cybercrime investigations across two units (Cyber Cell, Chengalpattu and Cyber Crime Wing, Chennai): digital evidence handling, incident documentation, threat triage, and public digital-safety awareness work. Built TOR-Unveil, a TOR traffic-analysis tool, for the TN Police Hackathon 2025.
Built and deployed web applications with Python (Flask), HTML, CSS and JavaScript; identified and remediated security vulnerabilities and documented the fixes.
Designed and delivered cybersecurity training content and knowledge-base documentation for learners new to the field.
An open-source CVE finder and CVSS risk-scoring tool built on the OWASP Risk Ranking Methodology, pulling live CVE data and applying a weighted scoring model. Used by bug-bounty hunters and small security teams.
A Chrome extension that encrypts session cookies with AES-256-GCM to reduce exposure to session hijacking and CSRF. Originally a final-year project.
Full web-application penetration test with documented findings, OWASP Top 10 classification, risk ratings and remediation recommendations.
A TOR network traffic-analysis tool using socket programming and packet inspection, built for the Tamil Nadu Police Hackathon 2025 as a real client engagement.
On TryHackMe: completed the Autopsy room (disk imaging, artefact analysis, forensic timelines) at 100%, alongside regular practice in SIEM alert triage, log analysis and MITRE ATT&CK mapping. Active CTF participant with an OSINT and threat-intel focus, and I attended the OWASP London Chapter meetup in March 2026.
