Burp Suite for Pentester: Hackbar

by Web Application Security Labs

An operational guide on integrating the highly specialized Hackbar Java plugin to dramatically accelerate manual payload injection and vulnerability probing.

“Isn’t it a bit time-consuming and a boring task to insert a new payload manually every time for a specific vulnerability? The Hackbar speeds up manual testing procedures by providing targeted payload dictionaries.”

Automated vulnerability scanners are phenomenal for detecting low-hanging fruit, but aggressive, custom exploitation requires manual payload crafting. For penetration testers operating primarily out of Burp Suite’s Repeater tab, constantly copying and pasting payloads from external text files is inefficient. Burp Suite for Pentester: Hackbar outlines exactly how to solve this bottleneck by embedding advanced payload dictionaries directly into your daily proxy workflow.

Installing Custom Java Extensions

Because the Hackbar plugin is not natively hosted on the BApp Store, the manual provides a necessary technical tutorial on side-loading custom .jar extensions via Burp’s Extender module. This process is a fundamental skill for any security professional who needs to run proprietary, unlisted, or heavily modified plugins during an engagement.

Arsenal at Your Fingertips

Once installed, the text transitions into execution. It demonstrates how Hackbar integrates seamlessly into the Repeater contextual menu, allowing testers to right-click specific data parameters and instantly inject highly structured attacks.

The guide breaks down exactly how to leverage these dropdown dictionaries targeting the most critical OWASP vulnerabilities:

  • SQL Injection (SQLi): Demonstrating how to rapidly fuzz column counts using automated ORDER BY payloads, rather than manual sequence typing.
  • Cross-Site Scripting (XSS) & OS Command Injection: Instantly dropping language-specific evasion payloads into parameters.
  • Local File Inclusion (LFI) & XXE: Utilizing Hackbar’s deep directory traversal and DTD parser templates to interrogate internal server configurations and file structures.

Who Is This Book REALLY For?

  • Manual Web Application Pentesters: If you spend 90% of your time in the Repeater tab, this guide introduces an architectural change that will save you hours of mundane typing and copying.
  • Web Assessors & Bug Hunters: For professionals who focus heavily on deep application logic rather than broad automated scanning, access to instant, context-specific payload dictionaries is an undeniable tactical advantage.
  • AppSec Teams: The payloads generated by Hackbar represent the exact syntactic structure that WAFs (Web Application Firewalls) must be tuned to detect and block.

The Bottom Line

Burp Suite for Pentester: Hackbar is a concise, highly practical engineering upgrade. It bridges the gap between manual precision and automated speed, ensuring that when an anomaly is detected, a tester has the immediate, onboard payload capacity to exploit it.
