Burpgpt - A Burp Suite Extension That Integrates OpenAI's GPT To Perform An Additional Passive Scan For Discovering Highly Bespoke Vulnerabilities, And Enables Running Traffic-Based Analysis Of Any Type
burpgpt
leverages the power of AI
to detect security vulnerabilities that traditional scanners might miss. It sends web traffic to an OpenAI
model
specified by the user, enabling sophisticated analysis within the passive scanner. This extension offers customisable prompts
that enable tailored web traffic analysis to meet the specific needs of each user. Check out the Example Use Cases section for inspiration.
The extension generates an automated security report that summarises potential security issues based on the user's prompt
and real-time data from Burp
-issued requests. By leveraging AI
and natural language processing, the extension streamlines the security assessment process and provides security professionals with a higher-level overview of the scanned application or endpoint. This enables them to more easily identify potential security issues and prioritise their analysis, while also covering a larger potential attack surface.
[!WARNING] Data traffic is sent to
OpenAI
for analysis. If you have concerns about this or are using the extension for security-critical applications, it is important to carefully consider this and review OpenAI's Privacy Policy for further information.
[!WARNING] While the report is automated, it still requires triaging and post-processing by security professionals, as it may contain false positives.
[!WARNING] The effectiveness of this extension is heavily reliant on the quality and precision of the prompts created by the user for the selected
GPT
model. This targeted approach will help ensure theGPT model
generates accurate and valuable results for your security analysis.

Please ensure that all system requirements, including a compatible version of Burp Suite
, are met before building and running the project. Note that the project's external dependencies will be automatically managed and installed by Gradle
during the build process. Adhering to the requirements will help avoid potential issues and reduce the need for opening new issues in the project repository.
Installation
1. Compilation
-
Ensure you have Gradle installed and configured.
-
Download the
burpgpt
repository:git clone https://github.com/aress31/burpgpt
cd .\burpgpt\ -
Build the standalone
jar
:./gradlew shadowJar
2. Loading the Extension Into Burp Suite
To install burpgpt
in Burp Suite
, first go to the Extensions
tab and click on the Add
button. Then, select the burpgpt-all
jar file located in the .\lib\build\libs
folder to load the extension.
Usage
To start using burpgpt, users need to complete the following steps in the Settings panel, which can be accessed from the Burp Suite menu bar:
- Enter a valid
OpenAI API key
. - Select a
model
. - Define the
max prompt size
. This field controls the maximumprompt
length sent toOpenAI
to avoid exceeding themaxTokens
ofGPT
models (typically around2048
forGPT-3
). - Adjust or create custom prompts according to your requirements.
Once configured as outlined above, the Burp passive scanner
sends each request to the chosen OpenAI model
via the OpenAI API
for analysis, producing Informational
-level severity findings based on the results.
Prompt Configuration
burpgpt
enables users to tailor the prompt
for traffic analysis using a placeholder
system. To include relevant information, we recommend using these placeholders
, which the extension handles directly, allowing dynamic insertion of specific values into the prompt
:
Placeholder | Description |
---|---|
{REQUEST} | The scanned request. |
{URL} | The URL of the scanned request. |
{METHOD} | The HTTP request method used in the scanned request. |
{REQUEST_HEADERS} | The headers of the scanned request. |
{REQUEST_BODY} | The body of the scanned request. |
{RESPONSE} | The scanned response. |
{RESPONSE_HEADERS} | The headers of the scanned response. |
{RESPONSE_BODY} | The body of the scanned response. |
{IS_TRUNCATED_PROMPT} | A boolean value that is programmatically set to true or false to indicate whether the prompt was truncated to the Maximum Prompt Size defined in the Settings . |
These placeholders
can be used in the custom prompt
to dynamically generate a request/response analysis prompt
that is specific to the scanned request.
[!NOTE] >
Burp Suite
provides the capability to support arbitraryplaceholders
through the use of Session handling rules or extensions such as Custom Parameter Handler, allowing for even greater customisation of theprompts
.

Roadmap
- Add a new field to the
Settings
panel that allows users to set themaxTokens
limit for requests, thereby limiting the request size. - Add support for connecting to a local instance of the
AI model
, allowing users to run and interact with the model on their local machines, potentially improving response times and data privacy. - Retrieve the precise
maxTokens
value for eachmodel
to transmit the maximum allowable data and obtain the most extensiveGPT
response possible. - Implement persistent configuration storage to preserve settings across
Burp Suite
restarts. - Enhance the code for accurate parsing of
GPT
responses into theVulnerability model
for improved reporting.
