vaccine

Description

This is not an emp3r0r module, you can use it to provide python3 environment and some utilities on your target host. To automate the process you can use vaccine.

How to pack

In an Alpine container, install the tools you want, and

#!/bin/bash

pack_bin() {
	libs="$(ldd "$1" | grep '=>' | awk '{print $3}')"
	[[ -d lib ]] || mkdir lib
	cp -v "$1" .
	patchelf --add-rpath ./lib "$(basename "$1")"
	patchelf --set-interpreter './lib/ld-musl-x86_64.so.1' "$(basename "$1")"
	for lib in $libs; do
		echo "Adding $lib"
		name=$(basename "$lib")
		if [ -L "$lib" ]; then
			cp -v "$(readlink -f "$lib")" "./lib/$name"
		else
			cp -v "$lib" "./lib/$name"
		fi
	done
}

pack_python() {
	python_bin="$(which python3)"
	python_bin_real="$(readlink -f "$python_bin")"
	python_ver=$(basename "$python_bin_real")
	echo "Packing $python_ver"

	pack_bin "$python_bin_real" || {
		echo "Failed to pack python3"
		exit 1
	}

	mv "$python_ver" python3
	cp -r "/usr/lib/$python_ver/" .

	# libexpat.so.1
	libexpat="$(readlink -f /usr/lib/libexpat.so.1)"
	cp -v "$libexpat" lib/libexpat.so.1

	# remove python cache
	(
		cd "$python_ver" && {
			find . -name __pycache__ -type d -exec rm -rf {} \; 2>/dev/null
			find . -name "*.pyc" -type f -exec rm -rf {} \;
		}
	)

}

[[ -e build ]] && rm -rf build
mkdir build && cd build &&
	(
		echo "fzf
gdbserver
nano
nmap
patchelf
socat
rg" >bins.txt

		# pack bins
		while read -r bin; do
			pack_bin "$(which "$bin")"
		done <bins.txt &&
			rm bins.txt &&
			pack_python

		# pack python and libs
		tar -cJvpf "python3.tar.xz" "$python_ver" &&
			rm -rf "$python_ver"
		tar -cJvpf libs.tar.xz lib &&
			rm -rf lib

		# pack vaccine
		tar -cJvpf ../vaccine.tar.xz .
