Ronflex

Attempts to suspend all known AV/EDRs processes on Windows using syscalls and the undocumented NtSuspendProcess API. Made with <3 for pentesters. Written in Rust.

WARNING

Ronflex tries to suspend all known AV/EDRs and other security product processes. There is a high chance that the system will be unstable after Ronflex did its thing ! Use at your own risks.

Known limitations

At the moment, Ronflex is not able to suspend processes protected by Anti-Malware Protected Process (AM-PPL), which is now quite common. WIP..

Todo

  • Loop over known processes to suspend them
  • Support for a specific process target
  • Move the NtSuspendProcess and NtClose API calls to syscalls
  • Move the remaining API calls to syscalls
  • Dynamically load the list of known processes from a file at compile time
  • Embbed a method to bypass AM-PPL. PPLmedic maybe ?

Quick start

No time ? Let's make it short then.

Binary

In case of an emergency, you will find a ready to deploy x64 binary for Windows in the repo Release section. However, consider taking the time to compile it yourself.

Cross-compile from Linux

Install and configure Rust:

Build the binary:

  • git clone https://github.com/Nariod/ronflex.git
  • cd ronflex
  • cargo build --release --target x86_64-pc-windows-gnu

Compile on Windows

Install and configure Rust:

Build the binary:

  • git clone https://github.com/Nariod/ronflex.git
  • cd ronflex
  • cargo build --release

Usage

Run the binary with the highest privileges you can and without argument to freeze all known security products:

  • ronflex.exe

Alternatively, you can freeze a specific target process by passing the exact process name:

  • ronflex.exe notepad.exe

Notepad put to sleep

Usage and details
