Velociraptor is a digital forensics and incident response platform, endpoint detection and response system, and visibility tool. It provides a query engine and remote forensic collector used to hunt for indicators of compromise and perform triage across a fleet of hosts. The system is distinguished by its specialized query language for interrogating host state and parsing binary files. It features a notebook environment that combines markdown documentation with executable query cells to standardize investigative workflows and enable collaborative reporting. The platform covers a wide range o

APT-Hunter is Threat Hunting tool for windows event logs which made by purple team mindset to provide detect APT movements hidden in the sea of windows event logs to decrease the time to uncover suspicious activity

Tracee is a cloud-native runtime security and forensics tool that uses eBPF to capture system calls and kernel events in real time. It operates as a standalone binary or a Helm-deployable agent for Kubernetes, normalizing system calls, network events, and container activities into a unified event pipeline for consistent analysis. The tool distinguishes itself through policy-driven event filtering using YAML-based rules, allowing users to target specific workloads and reduce noise during monitoring. It includes built-in threat detection signatures that flag suspicious behavioral patterns witho

Avilla Forensics is a free mobile forensic tool created in February 2021 to assist investigators in collecting information and evidence from mobile devices. Developed by Daniel Avilla, a police officer from São Paulo, the tool provides powerful features for logical data extraction and backup…

This repository is a community-driven collection of security content for Azure Sentinel, the cloud-native security information and event management (SIEM) platform from Microsoft. It serves as a central hub for sharing detection rules, threat hunting queries, interactive workbooks, and automated response playbooks, all contributed and maintained through a standard GitHub-based pull request workflow. The content is designed to help security operations teams quickly deploy proven detections, proactively hunt for threats, visualize security data, and orchestrate incident response actions without

RdpCacheStitcher is a tool that supports forensic analysts in reconstructing useful images out of RDP cache bitmaps. Using raw RDP cache tile bitmaps extracted by tools like e.g. ANSSI's BMC-Tools (https://github.com/ANSSI-FR/bmc-tools) as input, it provides a graphical user interface and…

Inception is a physical memory manipulation and hacking tool exploiting PCI-based DMA. The tool can attack over FireWire, Thunderbolt, ExpressCard, PC Card and any other PCI/PCIe interfaces.

BeaconEye scans running processes for active CobaltStrike beacons. When processes are found to be running beacon, BeaconEye will monitor each process for C2 activity.

Fast Incident Response

A tool collection for filtering and visualizing logon events. Designed to help answering the "Cotton Eye Joe" question (Where did you come from where did you go) in Security Incidents and Threat Hunts

Google Chrome forensic tool

Tetragon is an eBPF-based runtime security and observability toolset designed for Linux and Kubernetes environments. It functions as a security policy manager, observability agent, and enforcement engine that hooks into kernel functions and tracepoints to detect privilege escalation, container escapes, and unauthorized system activity. The project distinguishes itself through its ability to perform real-time, in-kernel enforcement, allowing it to synchronously terminate malicious processes or modify function return values before a system call completes. It provides deep Kubernetes integration

A DFIR tool written in Python.

Forensics acquisition framework designed to be extensible and secure
