BYOB

BYOB (Build Your Own Botnet) is an open source post exploitation framework for students, researchers and developers. While its primary purpose is educational the framework has been used for malicious purposes.

Key Insights

BYOB has a command and control server with a user-friendly interface, a custom payload generator for multiple platforms, and 12 post-exploitation modules. These modules include keylogging, screenshot capture, and privilege escalation, all the tools you need to exploit the system.

Customization and Extensibility

The framework is designed so users can add their code and features without having to build a command and control server or remote administration tool from scratch. This has led to many custom versions for specific attack scenarios.

Misuse and Security Impact

Although BYOB is educational BYOB has been used by malicious actors to build botnets and do unauthorized activities. The ease and flexibility of the framework make it a tool for people who want to do cyber attacks without having to know how to code.

Known Variants

BYOB has custom variants created by users for specific attack scenarios. The open source nature of the framework allows for modifications and extensions so there are many in the wild.

Mitigation Strategies

Install advanced threat detection to detect and block BYOB activity.
Keep systems up to date and patch vulnerabilities.
Do security awareness training to educate users about threats and best practices.
Block open-source malware tools and monitor the network for unusual traffic.

Targeted Industries or Sectors

BYOB is not limited to specific industries; its flexibility allows attackers to target any sector. Organisations with weak security are most vulnerable to attacks using this framework.
