VectorKernel - PoCs For Kernelmode Rootkit Techniques Research

By: Zion3R β€” April 18th 2024 at 12:30


PoCs for Kernelmode rootkit techniques research or education. Currently focusing on Windows OS. All modules support 64bit OS only.

NOTE

Some modules use ExAllocatePool2 API to allocate kernel pool memory. ExAllocatePool2 API is not supported in OSes older than Windows 10 Version 2004. If you want to test the modules in old OSes, replace ExAllocatePool2 API with ExAllocatePoolWithTag API.

Β 

Environment

All modules are tested in Windows 11 x64. To test drivers, following options can be used for the testing machine:

  1. Enable Loading of Test Signed Drivers

  2. debugging-in-windbg--cdb--or-ntsd">Setting Up Kernel-Mode Debugging

Each options require to disable secure boot.

Modules

Detailed information is given in README.md in each project's directories. All modules are tested in Windows 11.

Module Name Description
BlockImageLoad PoCs to block driver loading with Load Image Notify Callback method.
BlockNewProc PoCs to block new process with Process Notify Callback method.
CreateToken PoCs to get full privileged SYSTEM token with ZwCreateToken() API.
DropProcAccess PoCs to drop process handle access with Object Notify Callback.
GetFullPrivs PoCs to get full privileges with DKOM method.
GetProcHandle PoCs to get full access process handle from kernelmode.
InjectLibrary PoCs to perform DLL injection with Kernel APC Injection method.
ModHide PoCs to hide loaded kernel drivers with DKOM method.
ProcHide PoCs to hide process with DKOM method.
ProcProtect PoCs to manipulate Protected Process.
QueryModule PoCs to perform retrieving kernel driver loaded address information.
StealToken PoCs to perform token stealing from kernelmode.

TODO

More PoCs especially about following things will be added later:

  • Notify callback
  • Filesystem mini-filter
  • Network mini-filter

SwaggerSpy - Automated OSINT On SwaggerHub

By: Zion3R β€” February 19th 2024 at 11:30


SwaggerSpy is a tool designed for automated Open Source Intelligence (OSINT) on SwaggerHub. This project aims to streamline the process of gathering intelligence from APIs documented on SwaggerHub, providing valuable insights for security researchers, developers, and IT professionals.


What is Swagger?

Swagger is an open-source framework that allows developers to design, build, document, and consume RESTful web services. It simplifies API development by providing a standard way to describe REST APIs using a JSON or YAML format. Swagger enables developers to create interactive documentation for their APIs, making it easier for both developers and non-developers to understand and use the API.


About SwaggerHub

SwaggerHub is a collaborative platform for designing, building, and managing APIs using the Swagger framework. It offers a centralized repository for API documentation, version control, and collaboration among team members. SwaggerHub simplifies the API development lifecycle by providing a unified platform for API design and testing.


Why OSINT on SwaggerHub?

Performing OSINT on SwaggerHub is crucial because developers, in their pursuit of efficient API documentation and sharing, may inadvertently expose sensitive information. Here are key reasons why OSINT on SwaggerHub is valuable:

  1. Developer Oversights: Developers might unintentionally include secrets, credentials, or sensitive information in API documentation on SwaggerHub. These oversights can lead to security vulnerabilities and unauthorized access if not identified and addressed promptly.

  2. Security Best Practices: OSINT on SwaggerHub helps enforce security best practices. Identifying and rectifying potential security issues early in the development lifecycle is essential to ensure the confidentiality and integrity of APIs.

  3. Preventing Data Leaks: By systematically scanning SwaggerHub for sensitive information, organizations can proactively prevent data leaks. This is especially crucial in today's interconnected digital landscape where APIs play a vital role in data exchange between services.

  4. Risk Mitigation: Understanding that developers might forget to remove or obfuscate sensitive details in API documentation underscores the importance of continuous OSINT on SwaggerHub. This proactive approach mitigates the risk of unintentional exposure of critical information.

  5. Compliance and Privacy: Many industries have stringent compliance requirements regarding the protection of sensitive data. OSINT on SwaggerHub ensures that APIs adhere to these regulations, promoting a culture of compliance and safeguarding user privacy.

  6. Educational Opportunities: Identifying oversights in SwaggerHub documentation provides educational opportunities for developers. It encourages a security-conscious mindset, fostering a culture of awareness and responsible information handling.

By recognizing that developers can inadvertently expose secrets, OSINT on SwaggerHub becomes an integral part of the overall security strategy, safeguarding against potential threats and promoting a secure API ecosystem.


How SwaggerSpy Works

SwaggerSpy obtains information from SwaggerHub and utilizes regular expressions to inspect API documentation for sensitive information, such as secrets and credentials.


Getting Started

To use SwaggerSpy, follow these steps:

  1. Installation: Clone the SwaggerSpy repository and install the required dependencies.
git clone https://github.com/UndeadSec/SwaggerSpy.git
cd SwaggerSpy
pip install -r requirements.txt
  1. Usage: Run SwaggerSpy with the target search terms (more accurate with domains).
python swaggerspy.py searchterm
  1. Results: SwaggerSpy will generate a report containing OSINT findings, including information about the API, endpoints, and secrets.

TODO

Regular Expressions Enhancement
  • [ ] Review and improve existing regular expressions.
  • [ ] Ensure that regular expressions adhere to best practices.
  • [ ] Check for any potential optimizations in the regex patterns.
  • [ ] Test regular expressions with various input scenarios for accuracy.
  • [ ] Document any complex or non-trivial regex patterns for better understanding.
  • [ ] Explore opportunities to modularize or break down complex patterns.
  • [ ] Verify the regular expressions against the latest specifications or requirements.
  • [ ] Update documentation to reflect any changes made to the regular expressions.
