RustHound : A Cross-Platform BloodHound Collector Tool

October 16, 2023

In the realm of cybersecurity and network reconnaissance, RustHound emerges as a versatile hero.

This cross-platform BloodHound collector tool, built with Rust, breaks down the barriers between operating systems, making it a go-to solution for collecting critical network data.

Join us on a journey to explore the power and potential of RustHound in enhancing your cybersecurity arsenal.

Limitations

Not all SharpHound features have been implemented. Some exist in RustHound and not in SharpHound or BloodHound-Python. Please refer to the roadmap for more information.

Description

RustHound is a cross-platform BloodHound collector tool written in Rust, making it compatible with Linux, Windows, and macOS.

No AV detection and cross-compiled.

RustHound generates users, groups, computers, OUs, GPOs, containers, and domain JSON files that can be analyzed with BloodHound.

???? If you can use SharpHound, use it. Use RustHound as a backup solution if SharpHound is detected by AV or if it not compatible with your OS.

Using Makefile

You can use the make command to install RustHound or to compile it for Linux or Windows.

make install
rusthound -h

More command in the Makefile:

Default:
usage: make install
usage: make uninstall
usage: make debug
usage: make release

Static:
usage: make windows
usage: make windows_x64
usage: make windows_x86
usage: make linux_aarch64
usage: make linux_x86_64
usage: make linux_musl
usage: make macos
usage: make arm_musl
usage: make armv7

Without cli argument:
usage: make windows_noargs

Dependencies:
usage: make install_windows_deps
usage: make install_linux_musl_deps
usage: make install_macos_deps

Using Dockerfile

Use RustHound with Docker to make sure to have all dependencies.

docker build --rm -t rusthound .

# Then
docker run --rm -v ./:/usr/src/rusthound rusthound windows
docker run --rm -v ./:/usr/src/rusthound rusthound linux_musl
docker run --rm -v ./:/usr/src/rusthound rusthound macos

Using Cargo

You will need to install Rust on your system.

RustHound supports Kerberos and GSSAPI. Therefore, it requires Clang and its development libraries, as well as the Kerberos development libraries. On Debian and Ubuntu, this means clang-N, libclang-N-dev, and libkrb5-dev.

For example:

# Debian/Ubuntu
sudo apt-get -y update && sudo apt-get -y install gcc clang libclang-dev libgssapi-krb5-2 libkrb5-dev libsasl2-modules-gssapi-mit musl-tools gcc-mingw-w64-x86-64

Here is how to compile the “release” and “debug” versions using the cargo command.

git clone https://github.com/OPENCYBER-FR/RustHound
cd RustHound
cargo build --release
# or debug version
cargo b

The result can be found in the target/release or target/debug folder.

Below you can find the compilation methodology for each of the OS from Linux. If you need another compilation system, please consult the list in this link

Manually For Linux x86_64 Static Version

# Install rustup and Cargo for Linux
curl https://sh.rustup.rs -sSf | sh

# Add Linux deps
rustup install stable-x86_64-unknown-linux-gnu
rustup target add x86_64-unknown-linux-gnu

# Static compilation for Linux
git clone https://github.com/OPENCYBER-FR/RustHound
cd RustHound
CFLAGS="-lrt";LDFLAGS="-lrt";RUSTFLAGS='-C target-feature=+crt-static';cargo build --release --target x86_64-unknown-linux-gnu

The result can be found in the target/x86_64-unknown-linux-gnu/release folder.

Manually For Windows Static Version From Linux

# Install rustup and Cargo in Linux
curl https://sh.rustup.rs -sSf | sh

# Add Windows deps
rustup install stable-x86_64-pc-windows-gnu
rustup target add x86_64-pc-windows-gnu

# Static compilation for Windows
git clone https://github.com/OPENCYBER-FR/RustHound
cd RustHound
RUSTFLAGS="-C target-feature=+crt-static" cargo build --release --target x86_64-pc-windows-gnu

The result can be found in the target/x86_64-pc-windows-gnu/release folder.

Manually For MacOS Static Version From Linux

Amazing documentation

# Install rustup and Cargo in Linux
curl https://sh.rustup.rs -sSf | sh

# Add macOS tool chain
sudo git clone https://github.com/tpoechtrager/osxcross /usr/local/bin/osxcross
sudo wget -P /usr/local/bin/osxcross/ -nc https://s3.dockerproject.org/darwin/v2/MacOSX10.10.sdk.tar.xz && sudo mv /usr/local/bin/osxcross/MacOSX10.10.sdk.tar.xz /usr/local/bin/osxcross/tarballs/
sudo UNATTENDED=yes OSX_VERSION_MIN=10.7 /usr/local/bin/osxcross/build.sh
sudo chmod 775 /usr/local/bin/osxcross/ -R
export PATH="/usr/local/bin/osxcross/target/bin:$PATH"

# Cargo needs to be told to use the correct linker for the x86_64-apple-darwin target, so add the following to your project’s .cargo/config file:
grep 'target.x86_64-apple-darwin' ~/.cargo/config || echo "[target.x86_64-apple-darwin]" >> ~/.cargo/config
grep 'linker = "x86_64-apple-darwin14-clang"' ~/.cargo/config || echo 'linker = "x86_64-apple-darwin14-clang"' >> ~/.cargo/config
grep 'ar = "x86_64-apple-darwin14-clang"' ~/.cargo/config || echo 'ar = "x86_64-apple-darwin14-clang"' >> ~/.cargo/config

# Static compilation for macOS
git clone https://github.com/OPENCYBER-FR/RustHound
cd RustHound
RUSTFLAGS="-C target-feature=+crt-static" cargo build --release --target x86_64-apple-darwin --features nogssapi

The result can be found in the target/x86_64-apple-darwin/release folder.

Optimize The Binary Size

???? To obtain an optimized compilation of RustHound add the following compilation parameters at the end of the Cargo.toml file.

[profile.release]
opt-level = "z"
lto = true
strip = true
codegen-units = 1
panic = "abort"

The size of the binary will be considerably minimized. Basic cargo compiler commands can be used.

make windows

You can find the custom queries used in the demo in the resource folder.

Use the following command to install it:

cp resources/customqueries.json ~/.config/bloodhound/customqueries.json

Statistics

In order to make statistics on a DC with more LDAP objects, run the BadBlood on the domain controller ESSOS.local from GOAD. The DC should now have around 3500 objects. Below is the average time it takes to run the following tools:

Tool	Environment	Objects	Time	Command
SharpHound.exe	Windows	~3500	~51.605s	Measure-Command { sharphound.exe -d essos.local –ldapusername ‘khal.drogo’ –ldappassword ‘horse’ –domaincontroller ‘192.168.56.12’ -c All }
BloodHound.py	Linux	~3500	~9.657s	time python3 bloodhound.py -u khal.drogo -p horse -d essos.local -ns 192.168.56.12 –zip -c all
RustHound.exe	Windows	~3500	~5.315s	Measure-Command { rusthound.exe -d essos.local -u khal.drogo@essos.local -p horse -z }
RustHound	Linux	~3500	~3.166s	time rusthound -d essos.local -u khal.drogo@essos.local -p horse -z
