Persistent Powershell backdoor tool {😈}

Greetings

Keres a is Powershell rev-shell backdoor with persistence for windows and linux (pwsh)

it generates a PE exe that spawns a powershell process that starts a powershell rev-shell with persistence (if process stops an other one is spawned , if process is running don t spawn new process)

even if you exit break the shell you will the shell will always respawn on target

also it creates a Hidden batch and vbs file for persistent startup using reg.exe (value 'keres')

you can add -Ps (optional) to generate only a .ps1 file that do same thing

run the.ps1 file like the following for persistent startup (you can also change name of file btw ,reg value 'Meow'):

./keres.ps1 -p

note : it s preferable to use -go arg to build from a go file instead of python for better evasion

(python compilation with nuitka , go compilation with garble )

tested and fully bypass windows 10/11

do not upload binaries to virus total ;)

Update ! :

added obfuscation for the PE using Pyarmor

added go binary build with garbel obfuscation

to do :

add more options ( startup for linux...)

Prerequisite:

python

go (if you want to build golang binary)

SETUP :

git clone https://github.com/ELMERIKH/Keres

cd keres

pip install -r requirements.txt

go install mvdan.cc/garble@latest

export PATH=$PATH:~/go/bin

sudo apt install patchelf (Linux)

python3 keres.py

(PS : if on linux and want to compile a python win binary use wine to compile ./dist/pewpew.py or pewpew.py or just compile it on a windows env)
