Limitations

Not all SharpHound features are implemented yet but some are existing in RustHound and do 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. (Linux,Windows,MacOS)

No anti-virus detection and cross-compiled.

RustHound generate users,groups,computers,ous,gpos,containers,domains json files to analyze it with BloodHound application.

💡 If you can use SharpHound.exe, use it. Rusthound is a backup solution if SharpHound.exe is detected by AV or if SharpHound.exe isn't executable from the system where you have access to.

How to compile it?

Using Makefile

You can use 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 linux_musl
usage: make macos

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 -t rusthound .
docker run rusthound -h

Using Cargo

You need to install rust on your system (Windows/Linux/MacOS).

https://www.rust-lang.org/fr/tools/install

RustHound support Kerberos/GSSAPI but this means that it needs Clang and its development libraries, as well as the Kerberos development libraries. On Debian/Ubuntu, that means clang-N, libclang-N-dev and libkrb5-dev.

For example:

#Debian/Ubuntu
sudo apt-get -y update && sudo apt-get -y install gcc libclang-dev 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 from "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 "target/release" or in "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 : https://doc.rust-lang.org/nightly/rustc/platform-support.html

Manually for Linux x86_64 static version

#Install rustup and cargo in 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 "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 "target/x86_64-pc-windows-gnu/release" folder.

Manually for MacOS static version from Linux

Amazing documentation: https://wapl.es/rust/2019/02/17/rust-cross-compile-linux-to-macos.html

#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
#Uncomment line 32 and comment line 34 in Cargo.toml
RUSTFLAGS="-C target-feature=+crt-static" cargo build --release --target x86_64-apple-darwin

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

How to build the documentation?

git clone https://github.com/OPENCYBER-FR/RustHound
cd RustHound
cargo doc --open --no-deps

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, we run the BadBlood project on the domain controller ESSOS.local from GOAD. The DC has now around 3500 objects. An execution average time has been done and here are the output:

Tool	Environment	Objects	Time	Command line
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 [email protected] -p horse -z }
RustHound	Linux	~3500	~3.166s	time rusthound -d essos.local -u [email protected] -p horse -z
