AbdelRahman Mohamed HassanJunior Cyber Security Specialist
Summary

Investigative DFIR Specialist focused on host and network artifact triage across complex intrusion killchains. Experienced in extracting hidden payloads from volatile RAM, detecting sub-millisecond timestomping across NTFS records, and auditing Sysmon telemetry for covert persistence. Combines hands-on reverse engineering in Ghidra with automated forensic scripting to accelerate enterprise incident containment.

Projects

Enterprise Incident Response Capstone

• Reconstructed a complete APT killchain across Network, RAM, Disk, and Event Logs.

• Proved in-memory credential theft (LSASS dumping) by tracking Sysmon Event ID 10.

• Detected rootkit persistence by parsing offline SYSTEM registry hives for malicious boot-start drivers

Endpoint Forensics & Threat Hunting Scenarios

• Tracked attacker lateral movement and data exfiltration using Prefetch, Shellbags, and LNK analysis.

• Mathematically proved deliberate timestomping by correlating NTFS $MFT timestamp discrepancies.

• Hunted advanced fileless malware by dissecting Sysmon IDs 19-21 to uncover encoded PowerShell payloads hiding in WMI.

Memory & Network Forensics

• Utilized Volatility to extract injected code, VAD hooks, and hidden DLLs from raw memory dumps (e.g., Stuxnet triage).

• Conducted PCAP analysis using Wireshark to isolate malware beacons and extract malicious payloads from HTTP streams

Biometric Employee Access Scanner

Developed a biometric attendance/access prototype connecting hardware flow with software tracking.
