I break things to understand how to protect them.
I'm a cybersecurity fresher based in Pune, India — focused on SOC operations, threat detection, and ethical hacking. I hold RHCSA, RHCE, and CCNA certifications and I'm grinding toward CEH Master and OSCP.
I don't just follow tutorials. I build labs, write reports, and document everything — because understanding why a system fails matters more than just knowing it did.
- 🔭 Currently working on: CEH Master + OSCP prep
- 🌱 Building: Home SOC lab with expanding attack/detect coverage
- 💼 Looking for: Remote SOC Analyst or Junior Pentester roles

SIEM & Detection
Offensive Security
OS & Scripting
Built a home SIEM lab ingesting 500+ log events/day from Windows and Linux endpoints. Detected 3 brute-force attack patterns, wrote custom alert rules, and built dashboards that surfaced signal — not just noise.
Key takeaway: Real SIEM work is knowing what normal looks like so anomalies become obvious.

Stood up a controlled attack environment — Kali Linux + Metasploitable VMs. Ran full network scans with Nmap, surfaced 15+ open ports, mapped them to CVEs, and delivered a structured Hardening Report with remediation steps.
Not just scanning. Reports a real security team could act on.

Investigated 10+ real phishing samples. Extracted IOCs — malicious URLs, IPs, sender infrastructure — using VirusTotal and manual header analysis. Mapped attacker TTPs to MITRE ATT&CK framework. Also designed a full phishing simulation campaign for a Mastercard security awareness exercise.
Deep-dive threat intelligence report on LockBit ransomware. TTPs, infrastructure, IOCs, and defensive recommendations.
