What I Do

I bridge offensive security (exploitation, VAPT) with blue team (detection, response, automation). Most security practitioners focus on one side. I document both — every attack I run has a paired detection rule.

Current focus: Network-layer anomaly detection and SDN-based flow analysis at IIT Delhi CSC.


Featured Projects

# Repo What it demonstrates
1 VAPT-Portfolio 20+ assessments · MS17-010 · CVSS-aligned risk reporting
2 ad-exploitation-lab 5 AD attack chains · MITRE ATT&CK · paired Sigma rules · PCAP evidence
3 security-automation-scripts Nessus XML parser · SIEM threat detector · IR playbook trigger
4 sdn-network-lab Mininet mesh topology · Ryu L2 controller · OpenFlow 1.3

Project Deep-Dives

🟣 Active Directory Exploitation Lab

Repo: ad-exploitation-lab

End-to-end purple team lab — 5 attack chains, each with a paired Sigma detection rule and PCAP evidence:

Attack T-Code Detection Signal
Kerberoasting T1558.003 Event 4769 from non-service account
Pass-the-Hash T1550.002 Same NTLM hash reused across machines
DCSync T1033 Replication RPC from non-DC source
Lateral Movement (SMB) T1021.002 Admin$ access + cmd.exe via svchost
Credential Spray T1110.003 >5 × Event 4625 in 5 minutes

🔴 VAPT Portfolio

Repo: VAPT-Portfolio

20+ vulnerability assessments with professional documentation:

  • MS17-010 (EternalBlue) exploitation — CVSS 9.3
  • Full lifecycle: Recon → Scanning → Enumeration → Exploitation → Post-Exploitation
  • Risk-based reporting aligned with NIST CSF and CIS Controls

🔧 Security Automation Scripts

Repo: security-automation-scripts

Three production-ready scripts for SOC automation:

  • nessus_parser.py — Nessus XML → severity-sorted CSV with CVSS v3.1
  • siem_analyzer.py — detects brute force, privilege escalation, lateral movement
  • ir_trigger.sh — fires structured IR playbooks from alert payloads

🌐 SDN Network Lab

Repo: sdn-network-lab

Hands-on SDN lab built to understand network-layer security research:

  • Mininet 3-switch mesh with Open vSwitch
  • Ryu controller with MAC learning and OpenFlow 1.3 flow rules
  • Foundation for flow-based anomaly detection work

🔵 C|CT Lab Reports

Repo: CCT-Lab-Reports

EC-Council C|CT hands-on lab documentation — network analysis, defensive security, incident response.

What Makes Me Different

Most pentesters focus on finding vulnerabilities. I focus on defensibility — can this attack be detected? What does the event log look like? What is the Sigma rule? What's the IR playbook? That perspective is what makes a security engineer, not just a pentester.
