The Threat Hunter Playbook is a community-driven, open source project that provides detection logic, adversary tradecraft documentation, and resources for security professionals. The project organizes detection documents according to the MITRE ATT&CK framework, categorizing post-compromise adversary behavior into tactical groups. All content is presented in interactive notebook format, allowing users to access text, queries, expected output, and executable code in a single document. The notebooks enable security teams to run detection logic against pre-recorded security datasets either locally or through remote BinderHub cloud computing environments. This approach facilitates hands-on learning and validation of detection techniques. The project includes pre-recorded datasets mapped to specific adversarial techniques, providing practical examples for testing and validation. The interactive format supports both individual learning and collaborative development of detection capabilities. Resources cover various aspects of threat hunting including detection development methodologies, behavioral analysis patterns, and analytical validation techniques. The open source nature encourages community contributions and knowledge sharing across the security research community.
