Hi there, I'm Adnan A πŸ‘‹

I'm a Cybersecurity Bachelor's Student at Princess Sumaya University for Technology (PSUT) and an active CTF Player & Competitor.

In the CTF and security research world, my core specialization is OSINT with DFIR (Digital Forensics & Incident Response) β€” solving challenges where open-source reconnaissance directly intersects with deep digital forensics. Rather than treating them as separate fields, I integrate open-source intelligence gathering with forensic artifact analysis: digging into Git plumbing and commit logs, carving deleted files from web snapshots, extracting GPS EXIF metadata, and tracking threat actor campaign infrastructures.


🚩 Featured CTF Write-Ups & Research

Event: Cryptix CTF β€” Organized by HTU Cyber Club in collaboration with CYS-TECH
Category / Track: OSINT with DFIR (Digital Forensics & Incident Response)
Status: 5 / 5 Challenges Solved (100% Clear)

A complete, production-grade repository documenting step-by-step methodologies, reproducible CLI pipelines, custom extraction scripts, visual flowcharts, and primary disclosures for the complete OSINT with DFIR track:

πŸ”‘ Security & Software Projects

A secure web platform architected with strict defensive programming principles:

  • Privilege Separation: Multi-tier authentication distinguishing Customer, Administrator, and Root roles.
  • Access Control & Lifecycle: Role-Based Access Control (RBAC), reauthentication for sensitive actions, account state enforcement (Active, Banned, Frozen).
  • Database Hardening: PDO prepared statements, parameterized queries preventing SQL injection, transaction handling with row-level locks (FOR UPDATE).
  • Cryptographic Best Practices: Modern password hashing via password_hash() (Argon2/bcrypt) and safe session token lifecycles.

2. πŸ›‘οΈ SecureLog Analyzer

A Python security tool automating the parsing and triage of server log files for suspicious intrusion activity:

  • Detection Capabilities: Identifies brute-force authentication spikes, known attack patterns, and Indicators of Compromise (IOCs).
  • SIEM Principles: Implements rule-based parsing and alerting aligned with Blue Team security operations workflows.

A standalone credential vault implemented in Python with local cryptographic protection and safe memory/file handling.
