Responsibilities

Collecting, preserving, and analyzing forensic evidence across heterogeneous network infrastructure, edge routers, switches, cloud environments, and specialized network functions.
Serving as the technical lead during major security incidents—driving containment, root-cause analysis, threat eradication, and network recovery.
Interrogating full packet captures (PCAP), NetFlow/IPFIX, firewall logs, and router/switch artifacts to trace adversary lateral movement and data exfiltration.
Analyzing volatility memory dumps, volatile network state, process execution artifacts, and compromised system state during active intrusions to uncover malware execution, persistence mechanisms, and lateral movement tactics.
Architecting, authoring, and maintaining custom YARA rules for memory analysis, file carving, binary inspection, and continuous endpoint/network artifact matching.
Proactively dissecting advanced persistent threat (APT) TTPs, extracting indicators of compromise (IOCs), and converting forensic findings into actionable detections.
Scripting automated artifact collection, evidence ingestion, and triage workflows to accelerate response timelines.
Develop and refine specialized DFIR playbooks and runbooks for high-impact security incidents (e.g., state-sponsored intrusions, ransomware, supply chain compromises, and DDoS events).
Produce comprehensive, high-quality forensic investigation reports detailing attack timelines, root cause, evidence analysis, impact assessment, and technical remediation recommendations.
