SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This skill prevents accidental leakage of session cookies, Authorization tokens, and other users’ PII in screenshots and HAR attachments, which can invalidate bug-bounty submissions and create real privacy risk.

Core Features & Use Cases

  • Cookie redaction discipline: Identifies what to mask (session cookies, CSRF-bound tokens, Authorization, Cookie/Set-Cookie values) and recommends practical capture techniques (avoid capturing cookies, hide Burp request bodies, black-bar overlays when necessary).
  • PII black-bar protocol: Distinguishes between attacker-session data you can keep and other-user PII you must mask (names, emails, phones, faces/photos, sensitive IDs), while preserving triager-valuable structure (field presence and schema).
  • HAR sanitization via jq: Provides a concrete sanitization approach to strip sensitive headers/cookies and suggests additional response-body redaction when cross-account data is present.
  • Evidence readiness hygiene: Enforces before/after checklists (panel visibility, console screenshot practices, verification by searching for cookie substrings) and post-submission rotation guidance to render captured secrets dead.

Quick Start

Use evidence-hygiene to prepare a clean set of Bugcrowd-style attachments by redacting session cookies, black-barring other-user PII, and sanitizing any exported HAR file before you upload your PoC.

Frequently Asked Questions about evidence-hygiene

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

FAQPage Schema
How do I redact cookies and PII from HAR files before submitting a bug bounty report?

To redact cookies and PII from HAR files, sanitize your exports using jq-based logic to strip sensitive headers, session cookies, and Authorization tokens while preserving the triager-relevant metadata needed for validation.

What is the best way to black-bar other users' PII in bug bounty screenshots?

The best way to black-bar PII in bug bounty screenshots is to mask other users' names, emails, phones, and sensitive IDs with black-bar overlays, while preserving the field schema and presence so triagers can verify the vulnerability impact.

How do I hide sensitive Authorization headers and request bodies in Burp Suite Repeater screenshots?

To hide sensitive Authorization headers and request bodies in Burp Suite, apply capture discipline by avoiding cookie capture, hiding request bodies, and using black-bar overlays when necessary to prevent accidental secret leakage in PoC attachments.

Does evidence hygiene require rotating session cookies after submitting a bug bounty PoC?

Yes, evidence hygiene requires post-submission rotation guidance to render captured session cookies and Authorization tokens dead, ensuring that any secrets accidentally exposed in your bug report dossier cannot be reused.

Can I use jq to sanitize Chrome HAR exports for cross-account data leakage?

Yes, you can use jq to sanitize Chrome HAR exports by stripping sensitive headers and cookies, and applying additional response-body redaction rules to remove cross-account data leakage while maintaining the structural integrity needed for triage.
