Use when bypassing EDR/AV to run a payload — hook unhooking, direct/indirect syscalls, PPID spoofing, process injection, AMSI bypass, ETW patching, memory/sleep encryption, behavioral evasion.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# EDR Evasion
## When to Activate
- Planning EDR bypass during red team engagements
- Researching AV/EDR evasion techniques
- Developing implants that must survive endpoint detection
- Testing detection capabilities of security products
## Fundamentals
### AV vs EDR
**Antivirus (preventive)**:
- Static analysis: matching known signatures in files
- Dynamic analysis: limited behavioral monitoring/sandboxing
- Effective against known threats, weaker against advanced attacks
**EDR (proactive & investigative)**:
- Continuous endpoint monitoring
- Behavioral analysis at kernel level
- Anomaly detection and post-compromise visibility
- Prioritizes incident response and investigation
### Windows Execution Flow
```
Application → DLL (kernel32/ntdll) → Syscall → Kernel (ntoskrnl)

EDR hooks here
(userland hooks in ntdll)
```
## Hook Unhooking
### Userland Unhooking (ntdll.dll)
EDRs hook ntdll functions by replacing the first bytes with a JMP to their inspection code.
```c
// Method 1: Map fresh ntdll from disk

How to install
mdr add hypnguyen1209/offensive-claude/edr-evasion@sha256:0226ace5db65dfefThe line at the top of this page pins the label git:20260629.9f4a1a5, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
