SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Evidence-capture and PoC-redaction discipline for bug-bounty submissions: cookie redaction protocol (which fields to mask, Preview annotation / Burp panel hiding / DevTools workflow), PII black-bar discipline (what to mask in other-user data — names, emails, phones, faces — vs what is safe to leave — usernames, trace IDs, request bodies), HAR file sanitization (jq filters for Cookie/Set-Cookie/Authorization headers), Burp Repeater/Intruder screenshot hygiene (hide request body, show only Results table for rate-limit attacks), Chrome DevTools Console PoC patterns (credentials include so cookies are not echoed, labeled console.log), screenshot capture order, filename conventions, post-submission rotation hygiene. Use BEFORE any PoC screenshot, BEFORE attaching a HAR, or whenever preparing evidence with session cookies or other-user PII. Pairs with bugcrowd-reporting and report-writing.

Core Features & Use Cases

  • Cookie redaction protocol and PII masking to prevent leakage of sensitive data in artifacts.
  • HAR sanitization and structured evidence preparation using jq-driven transforms.
  • Screenshot hygiene and evidence-handling guidance for bug-bounty submissions.
  • DevTools, Burp, and Repeater best practices to minimize accidental exposure while preserving triage utility.
  • End-to-end workflow guidance pairing with report-writing and bugcrowd-reporting.

Quick Start

Before capturing any PoC screenshot or HAR, apply the evidence-hygiene checklist to redact sensitive data.

Frequently Asked Questions about evidence-hygiene

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I sanitize a HAR file for bug-bounty evidence submission?

To sanitize a HAR file for bug-bounty evidence, use jq-driven filters to remove sensitive Cookie, Set-Cookie, and Authorization headers. This ensures your HAR artifacts are compliant and safe to attach to submissions.

What is the proper cookie redaction protocol for PoC screenshots?

The proper cookie redaction protocol for PoC screenshots involves masking sensitive cookie fields and hiding Burp panel or DevTools data. This prevents accidental session leakage while preserving triage reproducibility for reviewers.

How do I redact PII in bug-bounty screenshots without losing triage utility?

Redact PII in bug-bounty screenshots by applying black-bar discipline to names, emails, phones, and faces, while leaving usernames, trace IDs, and request bodies visible to maintain triage utility for program analysts.

What is the best way to capture DevTools Console PoC evidence without leaking cookies?

The best way to capture DevTools Console PoC evidence without leaking cookies is using labeled console.log patterns and including credentials. This prevents echoing session cookies while clearly demonstrating the vulnerability reproduction.

Does evidence-hygiene work with Bugcrowd report submissions?

Yes, evidence-hygiene works directly with Bugcrowd report submissions by enforcing strict cookie and PII redaction rules across screenshots and HAR files. It ensures your artifacts meet program compliance standards before you submit.

When should I use screenshot hygiene for Burp Repeater and Intruder attacks?

Use screenshot hygiene for Burp Repeater and Intruder attacks when preparing rate-limit PoCs. You should hide request bodies and capture only the Results table to minimize accidental exposure of sensitive data while proving the vulnerability.
