Case and Malware Correlation Guide
Case and Malware Correlation Guide#
Malware analysis explains the file. Forensic case analysis explains whether that file appeared, executed, and affected a real environment. Connecting both gives stronger conclusions about compromise path, external connections, exfiltration likelihood, and user activity.
Data Worth Connecting#
| Malware Analysis Data | Case Evidence to Check |
|---|---|
| SHA-256 hash | Same-file presence, download path, execution traces |
| Filename | Prefetch, AmCache, RecentDocs, LNK, shell history |
| Created or modified time | Before-and-after timeline events and user activity |
| IP and domain | DNS, browser, proxy, firewall, network logs |
| Persistence signal | Autoruns, services, scheduled tasks, startup items |
| File access behavior | Sensitive folder access, archive, copy, deletion traces |
| MITRE mapping | Whether the case kill chain shows matching stages |
Recommended Workflow#
- Review hash, IOCs, risky behavior, and MITRE mapping in Malware Lab.
- Link the malware result to a forensic case.
- Ask AI analysis to search the case for the IOC and filename.
- Verify source artifacts and timestamps in manual review.
- Reconstruct appearance, execution, network, and data-access order in the timeline.
- Keep file analysis and environment evidence separate in the report.
Query Examples#
- "Find whether this malware IOC appears in the case evidence"
- "Show a one-hour timeline before and after this file first executed"
- "Compare the external IP with DNS, browser, and network logs"
- "Check whether sensitive-file access, archiving, or USB use followed execution"
- "Combine the malware result and case evidence into an incident-path summary"
Report Structure#
| Section | Content |
|---|---|
| File Analysis | Malware verdict, capabilities, IOCs, MITRE mapping |
| Environment Evidence | Execution, creation, access, and network traces in the case |
| Timeline | From file appearance to follow-on activity |
| Impact Assessment | Exfiltration, persistence, privilege escalation, further infection |
| Next Actions | IOC blocking, account review, further collection, original evidence verification |
Cautions#
- Absence of an IOC in the case does not prove absence of compromise.
- A malicious file without execution evidence should be assessed separately from impact.
- External connection evidence is stronger when network logs and timestamps align.
- File analysis and case evidence are complementary; neither should be the sole basis for final judgment.
