Supporting material availability

This catalog copy contains the inline guidance below, but does not include the following supporting paths. They are external prerequisites, not bundled files:

Ask for the original supporting material or an existing installation before using a step that depends on these paths; this catalog does not identify a verified download source for them. Resolve each path relative to that installation, inspect its contents, and verify any applicable license and execution prerequisites. Do not run a command or claim a referenced procedure was followed until its required file exists. Do not fabricate the missing scripts or treat an unrelated file with the same name as equivalent. Independent steps fully documented here can proceed within the user’s authorized scope; report any dependent step as unavailable.

Burp Project Parser

Search and extract data from Burp Suite project files using the burpsuite-project-file-parser extension.

When to Use

• Searching response headers or bodies with regex patterns
• Extracting security audit findings from Burp projects
• Dumping proxy history or site map data
• Analyzing HTTP traffic captured in a Burp project file

Prerequisites

This skill delegates parsing to Burp Suite Professional - it does not parse .burp files directly.

Required:

1. Burp Suite Professional - Must be installed (portswigger.net)
2. burpsuite-project-file-parser extension - Provides CLI functionality

Install the extension:

1. Download from github.com/BuffaloWill/burpsuite-project-file-parser
2. In Burp Suite: Extender → Extensions → Add
3. Select the downloaded JAR file

Quick Reference

Use the wrapper script:

{baseDir}/scripts/burp-search.sh /path/to/project.burp [FLAGS]

The script uses environment variables for platform compatibility:

• BURP_JAVA: Path to Java executable
• BURP_JAR: Path to burpsuite_pro.jar

See Platform Configuration for setup instructions.

Sub-Component Filters (USE THESE)

ALWAYS use sub-component filters instead of full dumps. Full proxyHistory or siteMap can return gigabytes of data. Sub-component filters return only what you need.

Available Filters

Default Approach

Start with headers, not bodies:

# GOOD - headers only, safe to retrieve
{baseDir}/scripts/burp-search.sh project.burp proxyHistory.request.headers | head -c 50000
{baseDir}/scripts/burp-search.sh project.burp proxyHistory.response.headers | head -c 50000

# BAD - full records include bodies, can be gigabytes
{baseDir}/scripts/burp-search.sh project.burp proxyHistory  # NEVER DO THIS

Only fetch bodies for specific URLs after reviewing headers, and ALWAYS truncate:

# 1. First, find interesting URLs from headers
{baseDir}/scripts/burp-search.sh project.burp proxyHistory.response.headers | \
  jq -r 'select(.headers | test("text/html")) | .url' | head -n 20

# 2. Then search bodies with targeted regex - MUST truncate body to 1000 chars
{baseDir}/scripts/burp-search.sh project.burp "responseBody='.*specific-pattern.*'" | \
  head -n 10 | jq -c '.body = (.body[:1000] + "...[TRUNCATED]")'

HARD RULE: Body content > 1000 chars must NEVER enter context. If the user needs full body content, they must view it in Burp Suite's UI.

Regex Search Operations

Search Response Headers

responseHeader='.*regex.*'

Searches all response headers. Output: {"url":"...", "header":"..."}

Example - find server signatures:

responseHeader='.*(nginx|Apache|Servlet).*' | head -c 50000

Search Response Bodies

responseBody='.*regex.*'

MANDATORY: Always truncate body content to 1000 chars max. Response bodies can be megabytes each.
