Location: Mumbai, India
Education: B.E. Computer Science & Engineering (Cybersecurity), TCET — CGPA 8.8/10 after SEM-6
Focus: Application Security | VAPT | Red Teaming | Bug Bounty
Mindset: Break it, understand it, report it, fix it.
I'm a cybersecurity undergraduate and full-stack-curious tech enthusiast who spends most days somewhere between Burp Suite and a code editor. My core lane is application security — but I like understanding the entire stack I'm attacking, which is why I also build web applications and tinker with cloud infrastructure on the side.
On the offense side, I've run web, API, and network penetration tests end-to-end — recon, exploitation, post-exploitation, CVSS-based triage — across live consultancy engagements, mapping red-team exercises back to MITRE ATT&CK. I dig into OAuth 2.0 / SAML / OIDC token-handling weaknesses, container misconfigurations, and privacy/GDPR gaps that most scanners miss.
On the build side, I write web apps to understand how the things I'm testing are actually put together, and I'm increasingly comfortable across AWS and Azure — provisioning environments, hardening configs, and finding the misconfigurations before an attacker does. I compete in CTFs to keep my offense sharp, and build my own tooling — from a Docker/Linux misconfiguration scanner to an ML-based Network Intrusion Detection System — whenever I want to go deeper than a write-up.

Security Tools
| Domain | Proficiency | Details |
|---|---|---|
| Web & API Penetration Testing | Advanced | Injection, broken auth, IDOR, business-logic flaws — OWASP Top 10 mapped |
| Vulnerability Scoring & Triage | Advanced | CVSS-based severity scoring to prioritize remediation |
| Auth Protocol Security | Advanced | OAuth 2.0 / SAML / OIDC — token hijacking, open redirect, SSRF patterns |
| Red Teaming & MITRE ATT&CK | Intermediate | Recon → exploitation → post-exploitation mapped to attacker TTPs |
| Cloud & Container Security | Intermediate | AWS IAM/S3 misconfig, Docker/Kubernetes hardening, CIS Benchmark checks |
| Network Security & Traffic Analysis | Intermediate | TCP/IP, packet analysis, anomaly & intrusion detection |
| Security Automation | Intermediate | Bash/Python tooling for scanning, CI/CD-integrated security checks |
| AI/ML for Security Detection | Developing | ML-based traffic classification, adversarial robustness exploration |
🐳 Docker Security Scanner
Automated Bash-based security scanner that audits Docker containers and Linux hosts for misconfigurations, privilege escalation paths, and exposed secrets — built to catch insecure defaults before they reach production in microservices environments.
| Category | Detail |
|---|---|
| Stack | Bash, Linux, Docker, Security Automation |
| Scale | Single-host & multi-container scan sessions |
| Performance | Lightweight shell-based checks, minimal runtime overhead |
| Security | Checks modeled on CIS Docker Benchmark controls |
| Impact | Surfaces insecure defaults pre-deployment, reducing container attack surface |

🛡️ AI-Based Network Intrusion Detection System
Python-based IDS that parses and classifies network traffic using ML models to flag anomalous behavior indicative of intrusions or lateral movement, with exploration into adversarial robustness for AI/ML-driven security detection.
| Category | Detail |
|---|---|
| Stack | Python, Random Forest, XGBoost, Decision Tree, Streamlit |
| Scale | Multi-class traffic classification (DDoS, Port Scan, Bot, Brute Force) |
| Performance | Evaluated across multiple ML models for detection accuracy |
| Security | Explores adversarial input handling and model robustness |
| Impact | Detects lateral movement & intrusion patterns from raw traffic |

🕸️ Live SSH/Telnet Honeypot — Azure Threat Intelligence
Deployed a live SSH/Telnet honeypot on Microsoft Azure using Cowrie and Fail2ban to capture real-world attacker behavior — credentials, commands, and geolocation data — for threat intelligence analysis.
| Category | Detail |
|---|---|
| Stack | Cowrie, Fail2ban, Microsoft Azure, Linux |
| Scale | Internet-facing honeypot, continuous live capture |
| Performance | Fail2ban IPS layered for automated blocking of repeat attackers |
| Security | Isolated honeypot environment to safely observe attacker TTPs |
| Impact | Real-world attack pattern & credential dataset for threat intel |
