Impact
Reduced repetitive first-pass enrichment into a single analyst-facing workflow.
Impact
Improved consistency in how suspicious files are documented before escalation.
Impact
Established a reusable base for deeper sandbox and memory-analysis extensions.
Deliverables
- Upload and triage pipeline for binaries, scripts, and archives.
- Normalized evidence outputs for hashes, YARA hits, strings, entropy, and heuristics.
- Analyst review interface with scoring cues and investigation notes.

- Triage workflow diagram slot reserved for upcoming artifact
Problem
Security teams often receive a large volume of suspicious files with limited context, forcing analysts to spend too much time on repetitive enrichment before they can determine what deserves deeper reversing effort.Approach
- Build a structured upload and triage pipeline that normalizes binaries, scripts, and archives into a consistent analysis workflow.
- Attach hash enrichment, YARA scanning, strings extraction, entropy checks, and unpacking heuristics in a single analyst-facing interface.
- Prioritize suspicious samples with a weighted scoring model that routes the right artifacts to deeper manual analysis.
Architecture / Workflow
- Ingestion service validates submissions, fingerprints artifacts, and expands supported archive types.
- Processing workers execute static checks, run signature rules, and generate normalized JSON evidence.
- A triage UI presents verdict cues, extracted indicators, and analyst notes while preserving the evidence chain.
Tools and Technologies Used
Python, YARA, Ghidra, Flask, Docker
Results / Impact
- Reduced repeated first-pass analysis steps into a single workflow.
- Improved consistency in how suspicious samples are documented before escalation.
- Created a reusable foundation for future sandbox and memory-analysis integrations.
Key Technical Takeaways
- Fast triage only matters when outputs remain useful to deeper investigators.
- Normalized evidence formats make automation easier to extend.
- Scoring needs analyst override paths to avoid false confidence.
