Open-source EDR kernel-component for system monitoring and DLL injection

BlueLight

BlueLight is an open-source kernel component for kernel-mode process activity monitoring and setup for user-mode API calls monitoring.

Goals

The goal of this project is to create a Windows kernel component for EDR system, specifically, BLUESPAWN - an open-source EDR.

Architecture

BlueLight built using file-system mini-filter driver which sends events to user-mode over communication port.

In addition, the driver uses injdrv for injecting custom DLL to every thread (right after loading kernel32.dll).

Monitoring

Currently implemented:

• Process Creation / Termination
• Thread Creation / Termination
• Remote Thread Creation
• Image Loading
