Computer Hacking Forensic Investigator (CHFI) v11 — Lesson 3: Memory, Malware, Network, Cloud, Mobile, and Timeline Analysis

Learning Objectives

• Explain the structures, services, data, settings, roles, and dependencies governing Memory Artifacts and Malware Indicators.
• Implement and validate Network Evidence, Cloud Logs, and Mobile Evidence and Timeline Correlation using reviewable evidence.
• Evaluate the condition where analysts reach the wrong conclusion because Mobile Evidence and Timeline Correlation evidence is incomplete and Malware Indicators context was not preserved and select a proportionate corrective response.

Detailed Topics

• Memory Artifacts applied to the course scenario, expected behavior, dependencies, controls, and evidence.
• Malware Indicators applied to the course scenario, expected behavior, dependencies, controls, and evidence.
• Network Evidence applied to the course scenario, expected behavior, dependencies, controls, and evidence.
• Cloud Logs applied to the course scenario, expected behavior, dependencies, controls, and evidence.
• Mobile Evidence and Timeline Correlation applied to the course scenario, expected behavior, dependencies, controls, and evidence.

Instructor Demonstration

The instructor traces an investigation team must preserve evidence integrity, reconstruct events, distinguish facts from hypotheses, and support legal or internal decision-making. The walkthrough connects tools, configuration or analysis logic, system messages, decisions, and evidence captured in the forensic case plan, acquisition log, artifact timeline, and defensible investigation report. It also tests the exception where analysts reach the wrong conclusion because Mobile Evidence and Timeline Correlation evidence is incomplete and Malware Indicators context was not preserved.

Hands-On Exercise

Complete a controlled, authorized EC-Council exercise covering Memory, Malware, Network, Cloud, Mobile, and Timeline Analysis and preserve the verified result in the forensic case plan, acquisition log, artifact timeline, and defensible investigation report.

1. Confirm scope, authorization, prerequisites, versions, identities, dependencies, and acceptance criteria.
2. Execute the workflow while recording settings, outputs, events, decisions, and system messages.
3. Test normal behavior, one boundary condition, and the stated exception without targeting real third-party systems.
4. Document corrections, evidence, ownership, retest criteria, rollback or recovery, and handover actions.

Scenario Analysis

• Identify which object, service, policy, setting, or sequence most strongly influences Memory Artifacts.
• Compare two defensible responses and explain technical, security, operational, legal, and support trade-offs.
• Determine how the forensic case plan, acquisition log, artifact timeline, and defensible investigation report should be approved, retained, retested, and updated.

Troubleshooting Guidance

Start where expected behavior first differs from the observed result. Check authorization, prerequisites, identity, configuration order, data quality, version compatibility, connectivity, status, resource limits, and evidence separately. Treat “analysts reach the wrong conclusion because Mobile Evidence and Timeline Correlation evidence is incomplete and Malware Indicators context was not preserved” as a hypothesis until logs, settings, captured outputs, and retest outcomes confirm the cause.

Validation Checklist

• Required components, identities, permissions, settings, safety controls, and dependencies are present.
• The forensic case plan, acquisition log, artifact timeline, and defensible investigation report connects each conclusion to objective, reviewable evidence.
• Normal processing, a boundary condition, dependency behavior, and the stated exception were tested.
• Corrections, ownership, retest criteria, rollback or recovery, documentation, and operational handover are complete.

Lesson Outcome

Learners can apply Memory, Malware, Network, Cloud, Mobile, and Timeline Analysis, explain the resulting security or operational behavior, and defend the outcome through the forensic case plan, acquisition log, artifact timeline, and defensible investigation report.
