Key Responsibilities

Incident Response & Investigation

Take end-to-end ownership of cybersecurity incidents from initial detection through closure.
Lead investigation of Critical, High, and complex security incidents and coordinate response activities across relevant teams.
Perform incident triage, scoping, containment, eradication, recovery, and post-incident analysis.

Coordinate with SOC, Threat Hunting, Threat Intelligence, IT, Cloud, Network, IAM, Application, Legal, and other stakeholders during major incidents.

Root Cause Analysis (RCA)

Perform detailed Root Cause Analysis for security incidents.
Determine the initial attack vector, contributing factors, security/control gaps, and reasons existing preventive or detective controls did not stop or detect the activity earlier.
Conduct post-incident reviews and lessons-learned sessions.
Develop clear corrective and preventive actions based on investigation findings.
Track remediation recommendations with relevant stakeholders through closure.
Prepare comprehensive RCA reports suitable for technical teams, management, and customers.

Malware Analysis

Perform static and dynamic malware analysis to understand malicious file behavior and capabilities.
Analyze suspicious executables, scripts, PowerShell commands, documents, URLs, and other artifacts.
Identify malware persistence mechanisms, command-and-control activity, network indicators, file-system changes, registry modifications, and related behaviors.
Extract IOCs and behavioral indicators for threat hunting and detection engineering.
Perform malware sandboxing and behavioral analysis where required.
Provide recommendations for detection, containment, and prevention based on malware-analysis findings.

Digital Forensics

Perform digital forensic investigations on endpoints and other relevant systems.
Analyze Windows/Linux artifacts, event logs, file systems, registry artifacts, browser artifacts, authentication logs, memory artifacts, and other forensic evidence.
Perform disk and memory analysis where required.
Collect and preserve digital evidence following appropriate forensic procedures and chain-of-custody requirements.
Build forensic timelines and reconstruct attacker activities.
Determine the scope and impact of compromise using forensic evidence.
Document forensic findings clearly and maintain investigation evidence appropriately.

Customer & Stakeholder Management

Act as a key technical point of contact for customers during cybersecurity incidents.
Lead incident calls and communicate investigation progress, impact, containment status, risks, and next steps.
Provide timely and accurate incident updates to customers and internal leadership.
Translate complex technical investigation findings into clear business-level communication.
Manage customer expectations during high-severity and time-sensitive incidents.
Present RCA and forensic investigation findings to customers and senior stakeholders.
Handle technical questions and confidently explain investigation methodology, evidence, conclusions, and recommendations.
Coordinate with multiple internal and customer teams to drive incidents toward timely resolution.

Incident Reporting & Documentation

Prepare detailed incident investigation reports, including:
Maintain accurate incident records, evidence, investigation notes, and supporting documentation.
Contribute to the development and improvement of Incident Response playbooks, SOPs, investigation procedures, and escalation processes.
