A guide to testing web applications with Burp Suite, a security tool that captures and edits browser requests before they reach a server.

In plain words
What is it for?
Intercepting HTTP traffic, modifying and replaying requests, reviewing request history, and running supported security scans.
Why use it?
It provides a structured way to inspect traffic, repeat requests, and look for web vulnerabilities.

Written for no agent in particular: nothing here depends on one.

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is ../../../etc/passwd.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

Burp Suite Web Application Testing scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Burp Suite Web Application Testing

Purpose

Execute comprehensive web application security testing using Burp Suite's integrated toolset, including HTTP traffic interception and modification, request analysis and replay, automated vulnerability scanning, and manual testing workflows. This skill enables systematic discovery and exploitation of web application vulnerabilities through proxy-based testing methodology.

Inputs / Prerequisites

Required Tools

  • Burp Suite Community or Professional Edition installed
  • Burp's embedded browser or configured external browser
  • Target web application URL
  • Valid credentials for authenticated testing (if applicable)

Environment Setup

  • Burp Suite launched with temporary or named project
  • Proxy listener active on 127.0.0.1:8080 (default)
  • Browser configured to use Burp proxy (or use Burp's browser)
  • CA certificate installed for HTTPS interception

Outputs / Deliverables

Primary Outputs

  • Intercepted and modified HTTP requests/responses
  • Vulnerability scan reports with remediation advice
  • HTTP history and site map documentation
  • Proof-of-concept exploits for identified vulnerabilities

Core Workflow

Phase 1: Intercepting HTTP Traffic

Launch Burp's Browser

Navigate to integrated browser for seamless proxy integration:

  1. Open Burp Suite and create/open project
  2. Go to Proxy > Intercept tab
  3. Click Open Browser to launch preconfigured browser
  4. Position windows to view both Burp and browser simultaneously
Configure Interception

Control which requests are captured:

Proxy > Intercept > Intercept is on/off toggle

When ON: Requests pause for review/modification
When OFF: Requests pass through, logged to history
Intercept and Forward Requests

Process intercepted traffic:

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
