cathook announcements channel in telegram

The software is most likely detected. Only use it on accounts you won't regret getting VAC banned.

You can chat with other cathook users in my official telegram group.

Right now cathook isn't in its greatest state, a lot of things may not work/crash the game, please open issues on github using this page.

cathook is a training software designed for Team Fortress 2 for Linux. cathook includes some joke features like

• Backpack.TF API integration with playerlist GUI, allowing you to see players' inventory values
• Ignore Hoovy
• Encrypted chat
• Chance to get manually VAC banned by Valve

and a lot of useful features, including

• Anti Backstab with option to say "No" voice command when spy tries to backstab you
• Heal Arrows exploit (overheal an enemy for 1200 health with single huntsman arrow, you can also do it with buildings!)
• Extremely customizable spam (you can make spam lines that'll include name of random dead enemy pyro or sniper)
• Follow Bots
• Working crit hack (does not work right now (works right now))

FULL LIST OF FEATURES HERE (list might be outdated)

You need CMake to build cathook, CMake should take care of dependencies

Install libglez, libxoverlay and simple-ipc

• Clone the repo of library (git clone <URL>)
• mkdir build && cd build
• cmake ..
• make && sudo make install

Install cathook

• git clone --recursive https://github.com/nullworks/cathook
• cd cathook && mkdir build && cd build
• cmake .. && make
• sudo make data

You can use gcc-7 for compiling cathook if you add -e CC=gcc-7 CXX=g++-7 to make command line

Ubuntu gcc6 installation: (check if you have gcc-6 installed already by typing gcc-6 -v

sudo apt update && sudo apt install build-essential software-properties-common -y && sudo add-apt-repository ppa:ubuntu-toolchain-r/test -y && sudo apt update && sudo apt install gcc-snapshot g++-6-multilib gcc-6 g++-6 -y

Ubuntu other dependencies installation:

sudo apt update && sudo apt install git libssl-dev:i386 libboost-all-dev libc6-dev:i386 gdb libsdl2-dev libglew-dev:i386 libfreetype6-dev:i386 -y 

Arch gcc6 & dependencies installation:

sudo pacman -U https://archive.archlinux.org/packages/g/gcc-multilib/gcc-multilib-6.3.1-2-x86_64.pkg.tar.xz https://archive.archlinux.org/packages/g/gcc-libs-multilib/gcc-libs-multilib-6.3.1-2-x86_64.pkg.tar.xz https://archive.archlinux.org/packages/l/lib32-gcc-libs/lib32-gcc-libs-6.3.1-2-x86_64.pkg.tar.xz && sudo cp -r /usr/include/c++/6.3.1/ /tmp/ && sudo pacman -S gdb gdb-common glew1.10 glew lib32-glew1.10 rsync lib62-gcc-libs gcc-libs-multilib gcc-multilib --noconfirm && yes | sudo cp -r  /tmp/6.3.1/ /usr/include/c++/

If you don't use Ubuntu or Arch (or if Arch script gets outdated), here's the list of what cathook requires:

• cmake-qt-gui (optional, for easy configuring)
• cmake
• gcc-7
• g++-7
• gcc-7-multilib
• g++-7-multilib
• glew
• gdb (for the injection script, you can use different injector if you want)
• libssl-dev:i386
• libc6-dev:i386
• libsdl2-dev
• libglew-dev:i386
• libfreetype6-dev:i386
• libboost-all-dev
• rsync (used for copying shaders/fonts to tf2 data directory, check-data script)

Cathook installation script:

git clone --recursive https://github.com/nullworks/cathook && cd cathook && bash build-tf2

Errors while installing?

/usr/include/c++/5/string:38:28: fatal error: bits/c++config.h: No such file or directory You don't have gcc-7-multilib installed correctly.

Anything related to glez or xoverlay

Install libglez and libxoverlay.

src/<any file>: fatal error: mathlib/vector.h: No such file or directory You didn't download Source SDK. DO NOT DOWNLOAD CATHOOK USING "DOWNLOAD .ZIP" FROM GITHUB. USE git clone --recursive!

If you are using another distro, make sure to have required dependencies installed.

Run the update script in cathook folder.

Cathook requires a special data folder (contains shaders, font files, walkbot paths, etc). This folder is located at /opt/cathook/data and is generated automatically when you compile cathook.

sudo ./attach to attach cathook into TF2. Optionally, you can provide an argument number (0-n - #) to provide the TF2 process ID (for bots).

sudo ./attach-backtrace to attach and print backtrace incase TF2 crashes. Some users report that this causes FPS drop in-game. This is recommended to grab a log of what went wrong if Cathook is crashing on you.

cathook-ipc-server allows you to run and control Followbots to do your evil bidding in-game. The installation for Followbots is quite complex, and will not be covered on this page. Obviously, you must have several user accounts ready to run TF2.
A guide for Followbots can be found here: How to setup and use followbots.
You may also ask someone in our discord server to help you out.

The installation script is as followed:

git clone --recursive https://github.com/nullworks/cathook-ipc-server && cd cathook-ipc-server && make -j4

To run the Followbot server, run ./bin/cathook-ipc-server. You can also use ./bin/cathook-ipc-server &>/dev/null & to run it in background.
