About Me
I am a 3rd-year student in Lovely Professional University and yes a normal person just like you, my core focus is on Infrastructure Security, Adversary Emulation, Administering different tasks, Blue team operations. Unlike typical red teamers, I believe in mastering the defensive side first—diving deep into Linux & Windows System Administration to understand exactly what I am attacking or protecting.
I prefer a hands-on, research-driven approach, utilizing extensive home labs to simulate Phishing Campaigns, set up basic C2 Operations, and practice Blue Team monitoring. Currently, I am also refining my low-level programming skills in C to better understand operating system internals.
Skills & Technologies
System Administration
- Linux: Deep knowledge of permissions, process management, Bash scripting, and service configuration.
- Windows: Active Directory (AD) deployment, GPO management, PowerShell automation, and domain hardening.
Security Operations
- Red Teaming: Phishing Campaign Development, Basic C2 Infrastructure (setup & connectivity), Active Directory Exploitation.
- Blue Teaming: Log Analysis, SIEM fundamentals, Windows Forensics, Linux Forensics, and System Hardening.
Languages & Tools
- Languages: Python (Automation), C (Low-level dev), Bash, powershell.
- Tools: Metasploit, Burp Suite, Wireshark, Sysinternals, Powershell Empire, shellter, Evilginx2, GoPhish, BloodHound, Mimikatz, Responder, NetExec, ffuf, proxychains, suricata, wazuh
Projects
1. Enterprise Home Lab & Adversary Emulation
The core of my practical learning.
- Infrastructure: Deployed a complete Active Directory environment with Domain Controllers, Workstations, and Linux servers.
- Red Operations: Executed simulated Phishing campaigns and deployed basic C2 agents to test network defenses and persistence.
- Blue Operations: Monitored traffic and system logs to detect the artifacts generated by my own attacks, bridging the gap between Red and Blue teaming.
2. Build Your Own Shell (C Language)
Part of CodeCrafters Challenge
- Developing a POSIX-compliant shell in C.
- Implementing core system interactions, process creation, and signal handling to understand Linux internals at a deeper level.
3. Remote Control (RC) Car
- Designed and assembled a custom RC car, handling component selection, circuit assembly, and motor control logic.
- Key components used - Arduino Uno , L298N Motor Driver, DC Gear Motors, HC-05 Bluetooth Module, Li-ion Batteries.
4. Cybersecurity Blog & Knowledge Base
- Built and maintained this site using Hugo & PaperMod.
- Documenting System Administration guides, penetration testing methodologies, Blue Team Operations and lab configurations.

Experience
Cybersecurity Student / Researcher Self-Employed / Academic | 2025 - Present
- Enterprise System Administration: Designed and administered a hybrid Linux/Windows environment mimicking corporate scale. Configured core services (AD DS, DNS, DHCP), enforced network isolation via VLANs, and utilized Python & Bash to automate configuration management and system hardening.
- Network Penetration Testing: Conducted end-to-end assessments to validate security postures, utilizing simulated phishing campaigns via azure for initial access and deploying basic C2 infrastructure to test network persistence. Successfully executed complex exploit chains targeting Active Directory misconfigurations and lateral movement paths.
- Security Infrastructure Implementation: Deployed and integrated a centralized security monitoring stack (Wazuh, Suricata, Zeek) to audit system logs and network traffic, ensuring comprehensive visibility and verifying the detection of specific attack signatures.
CTFs
- Active participant in CTF events (HackTheBox, PicoCTF).
- Focused on realistic network scenarios, privilege escalation, and lateral movement challenges.
