SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It prevents bug-bounty evidence from leaking session cookies, authorization tokens, and other users’ personally identifiable information (PII) by enforcing a repeatable capture-and-redaction discipline before screenshots or HARs are attached.

Core Features & Use Cases

  • Cookie redaction protocol: Masks session-bearing cookies and Authorization/CSRF secrets while allowing triager-useful metadata like trace IDs and correlation headers.
  • PII black-bar discipline: Distinguishes between other-user PII that must be redacted (names, emails, phones, faces) and non-sensitive proof elements that can remain visible (field keys, shapes, your attacker-session identifiers).
  • HAR sanitization: Provides jq-based header and cookie-stripping patterns to remove Cookie/Authorization/Set-Cookie values prior to attachment.
  • Screenshot hygiene for Burp and DevTools: Recommends hiding request bodies, capturing only the Results table where appropriate, and using clean DevTools Console PoC patterns that avoid echoing sensitive credentials.
  • Evidence workflow guardrails: Enforces pre-capture checklists, screenshot capture order, filename conventions, and post-submission rotation hygiene to ensure captured secrets are invalidated.

Quick Start

Use the evidence-hygiene skill before capturing any screenshot or exporting a HAR for a bug-bounty submission so that all session cookies and any other-user PII are redacted according to the protocol.

FAQPage Schema
How do I redact session cookies and PII from bug bounty evidence before submission?▼

HAR sanitization uses jq-based header and cookie-stripping patterns to remove sensitive Cookie, Set-Cookie, and Authorization values from HAR exports, ensuring session tokens are not exposed during triager triage.

What is the best way to sanitize a HAR file for triage without removing useful metadata?▼

HAR sanitization uses jq-based header and cookie-stripping patterns to remove sensitive Cookie, Set-Cookie, and Authorization values from HAR exports, preserving triager-useful metadata like trace IDs and correlation headers for effective triage.

How do I capture clean Burp Suite screenshots for IDOR proof-of-concept without leaking credentials?▼

Clean Burp Suite screenshots for IDOR PoCs are captured by hiding sensitive request bodies, masking Cookie and Set-Cookie values, and capturing only the necessary Results table to prevent exposing session tokens or user PII.

Can I use Chrome DevTools Console PoCs to demonstrate state-change workflows safely?▼

Yes, Chrome DevTools Console PoCs can demonstrate state-change workflows safely by using clean patterns that avoid echoing sensitive credentials and adhering to evidence-hygiene redaction rules for Authorization headers and PII fields.

Does bug bounty evidence redaction require rotating captured session tokens after submission?▼

Yes, bug bounty evidence redaction includes post-submission rotation hygiene as a workflow guardrail, ensuring that any session cookies or authorization tokens captured during PoC creation are invalidated after the evidence is submitted.
