Methodology

A transparent, stepwise approach designed for rigor and reproducibility.

We combine automated analysis (e.g., static/dynamic scans, fuzzing) with thorough manual review and reproducible PoCs to produce reports you can trust.

  1. Scoping & Assumptions

    Define scope, threat model, trust boundaries, and environment assumptions.

  2. Automated Scans & Coverage

    Run static/dynamic analysis and fuzzing; ensure baseline test coverage.

    Tools often include linters and scanners; fuzz with common OSS tooling.

  3. Manual Review & Invariant Reasoning

    Deep manual analysis, invariants, privilege boundaries, and economic security.

  4. Exploit Simulation & PoC Validation

    Reproduce findings with proof-of-concept exploits and scenario testing.

  5. Findings, Severity, Recommendations

    Document vulnerabilities, severity, and actionable remediations with references.

  6. Remediation Verification

    Verify fixes, update findings, and publish transparent diff in report.
