Education
Bachelor of Computer Applications (BCA)
Calicut University, Kerala
2022 – 2025
Professional Summary

Offensive security practitioner (BCA graduate) with hands-on experience across the full attack lifecycle — reconnaissance, exploitation, and post-exploitation — and blue team proficiency in SIEM-driven detection and incident response. EC-Council CSA certified. Led an independent VAPT engagement on Calicut University's web infrastructure, uncovering injection and authentication flaws with a client-ready report. Builds security tooling in Python/Go, including a recon framework and OSINT suite, alongside reverse engineering work in Ghidra and YARA.

Work Experience
Independent Security Researcher & Cybersecurity Consultant
Self-Directed / Freelance · Kozhikode, Kerala
2023 – Present
  • Conducted an independent web VAPT engagement on Calicut University's public infrastructure using OWASP methodology; identified injection flaws, broken authentication, and server misconfigurations; delivered a severity-rated remediation report.
  • Built and open-sourced three security tools — InstaGrep (OSINT suite), ReconFrame (reconnaissance framework), and Udyama (CTF machine simulating Linux privilege escalation).
  • Ran multi-phase attack simulations in self-built home labs (AD red team lab, malware analysis sandbox), documenting findings in structured technical reports.

Projects & CTFs
ReconFrame — Advanced Reconnaissance Framework
Penetration Testing, Python, Tool Development  ·  github.com/Jishnuec/reconframe
  • Situation: Penetration test reconnaissance required manually invoking 12+ separate tools with no unified workflow or consistent output formatting.
  • Action: Built a Python terminal framework integrating Nmap, Whois, DNS enumeration, and 9+ other tools — with intelligent IP/domain auto-detection and clean ANSI-formatted output.
  • Result: Consolidated full attack-surface reconnaissance into a single command — eliminating manual tool-switching and standardising output for professional reporting; reduced recon phase setup time significantly.
InstaGrep v4.0 — Instagram OSINT Desktop Tool
OSINT, Python, Desktop Application  ·  github.com/Jishnuec/InstaGrep
  • Situation: Manual Instagram OSINT investigations were slow, inconsistent, and produced no structured output suitable for professional reporting.
  • Action: Engineered a ~3,000-line Python desktop application with a full GUI, integrating Instagrapi for data extraction, Matplotlib for behavioral pattern visualization, and automated multi-format export (PDF/CSV/JSON).
  • Result: Automated OSINT data collection and report generation — cutting manual investigation time by an estimated 60%; delivered a complete professional-grade suite covering profile analysis, media download, and activity timeline reconstruction.
Calicut University — Vulnerability Assessment Report
Web Security, VAPT, Professional Report  ·  (anonymous)
  • Situation: Calicut University's web platform had no prior formal security assessment, leaving unknown attack surfaces exposed to potential threat actors.
  • Action: Conducted a structured web vulnerability assessment — mapped 15+ endpoints, tested for injection flaws, authentication weaknesses, and server misconfigurations following OWASP Top 10 methodology.
  • Result: Identified and documented multiple severity-rated vulnerabilities; delivered a professional remediation report treating the engagement as a real-world client deliverable — demonstrating both technical depth and communication skills.
Driver Vigilance System — Real-Time Driver Monitoring (Group Project)
Machine Learning, Computer Vision, Python, Safety Systems  ·  2025
  • Situation: Distracted and drowsy driving is a leading cause of road accidents; most existing solutions are hardware-intensive or cost-prohibitive for everyday drivers.
  • Action: Collaborated on a multi-component system integrating ML-based video analysis to detect distraction behaviors (phone usage, turning around, reaching to the rear seat) and drowsiness in real time via smartphone camera and sensors — alongside a Driver App for real-time alerts, a Partner App for remote monitoring, and specialized emergency-coordination modules for police, ambulance, and hospital stakeholders; unified through a central web dashboard managing data flow between all actors.
  • Result: Delivered a full end-to-end safety platform demonstrating applied ML/CV, multi-app architecture, and emergency-response integration — setting a practical benchmark for accident prevention through early behavioral detection and automated emergency escalation.
Udyama (उद्यम) — Custom CTF Machine
CTF Design, Linux, Privilege Escalation  ·  Feb 2026  ·  archive.org/details/Udyama
  • Situation: The community lacked intermediate-to-advanced Linux privilege escalation CTF challenges grounded in realistic, multi-step attack techniques.
  • Action: Designed and packaged a custom Ubuntu 22.04 OVA with 2 flags (User + Root), realistic privilege escalation chains, and deliberate persistence mechanisms modeled on real-world attacker TTPs.
  • Result: Released publicly on Archive.org — freely available to the global cybersecurity community; demonstrates attack chain design from an attacker and defender perspective, and deep Linux internals knowledge.
