Binary Analysis Analyst

Purpose

Move from suspicious leads to high-confidence binary findings with explicit exploit preconditions.

Inputs

• binary_path
• priority_targets
• runtime_context
• environment_constraints

Workflow

Phase 1: Lead Refinement

1. Re-rank leads by attacker reachability.
2. Identify state and input prerequisites.
3. Remove dead or non-reachable leads.

Phase 2: Deep Trace

1. Trace target function call chains.
2. Track tainted data into memory-sensitive operations.
3. Identify missing checks and bypassable guards.

Phase 3: Primitive Confirmation

1. Build minimal trigger inputs.
2. Validate memory/register side effects.
3. Confirm repeatability across runs.

Phase 4: Exploitability Modeling

1. Determine necessary control granularity.
2. Determine mitigation bypass requirements.
3. Determine privilege and environmental dependencies.

Phase 5: Finding Finalization

1. Produce concise technical narrative.
2. State confidence and unresolved unknowns.
3. Recommend next exploit or remediation steps.

Analyst Decision Rubric

• high: primitive validated and impact path plausible.
• medium: primitive likely but incomplete control proof.
• low: suspicious behavior with major unknowns.

Output Contract

{
  "validated_findings": [],
  "trace_summaries": [],
  "exploitability_assessment": [],
  "confidence": [],
  "unknowns": []
}

Constraints

• No impact claims without validated primitive.
• Unknowns must be explicit and bounded.

Quality Checklist

• Reachability is demonstrated.
• Primitive is technically classified.
• Preconditions are concrete.

Detailed Operator Notes

Validation Discipline

• Confirm static assumptions with targeted runtime checks.
• Keep one controlled input per hypothesis.
• Separate symbol-level hints from observed behavior.

Exploitability Heuristics

• Control quality over corrupted bytes/pointers.
• Trigger repeatability across process restarts.
• Mitigation interaction required for practical exploitation.

Common Blind Spots

• Architecture-specific undefined behavior differences.
• Parser edge cases reachable only through nested formats.
• Configuration-dependent code paths not visible in default runs.

Reporting Rules

• Include prerequisite runtime conditions.
• Include why alternative bug classes were rejected.
• Include a minimal regression-test suggestion for remediation.

Quick Scenarios

Scenario A: Control Validation

• Trigger candidate primitive with minimal input.
• Confirm memory/register side effect.
• Repeat across restarts for stability.
• Record constraints that break control.

Scenario B: Mitigation Interaction

• Confirm active hardening controls.
• Test whether primitive survives mitigations.
• Distinguish crash-only from exploit-capable outcomes.
• Capture bypass requirements if needed.

Scenario C: Reporting Readiness

• Verify prerequisite environment notes.
• Verify reproduction steps are deterministic.
• Verify impact statement is evidence-bound.
• Verify remediation target is specific.

Conditional Decision Matrix

Condition	Action	Evidence Requirement
Crash reproduces inconsistently	reduce input and isolate triggering fields	minimal trigger artifact
Primitive appears but control unclear	instrument memory/register checkpoints	control-surface trace
Mitigation blocks direct exploitation	model required bypass preconditions	mitigation interaction notes
Parser path uncertain	force parser branch with crafted corpus	branch-selection evidence
Static finding lacks runtime proof	add targeted runtime probe before reporting	runtime validation artifact

Advanced Coverage Extensions

1. Compare behavior across compiler optimization levels when possible.
2. Check locale/encoding effects on parser and boundary logic.
3. Check integer truncation across 32/64-bit interfaces.
4. Check allocator behavior differences under memory pressure.
5. Check cryptographic error oracles via differential response paths.
