# 3. Install the required tools (Linux distro) sudo apt update sudo apt install -y unzip unrar p7zip-full binutils \ radare2 ghidra yara clang gdb qemu-user-static \ mingw-w64-tools mingw-w64-common \ python3-pip && pip3 install lief capstone The binary is a 32‑bit Windows PE ( PE32 ). On a modern 64‑bit Linux host we will need the wine runtime for dynamic testing and mingw tools for static analysis. 3. Extraction & Basic File Inspection # Extract the rar archive unrar x pc.rar # → we obtain pc.exe (size ≈ 44 KB) # File type file pc.exe # pc.exe: PE32 executable (GUI) Intel 80386, for MS Windows

# Key location: [0x00401000]> s 0x00407000 [0x00407000]> pd 12 # → key = "kKMo0M_cRaZ" Extract both blobs: www kkmoom com pc rar

#!/usr/bin/env python3 import sys

def get_rva_to_offset(pe_path, rva): # Use pefile to translate import pefile pe = pefile.PE(pe_path) return pe.get_offset_from_rva(rva) Dump the encrypted blob & the key #

The buffer buf is filled from an encrypted static array ( encrypted ) using a XOR key that lives in the .rdata section. 5.4. Dump the encrypted blob & the key # Encrypted data location (r2): [0x00401000]> s 0x00406000 # (example address) [0x00406000]> pd 20 # → .rdata: 0x100 bytes = encrypted payload s 0x00406000 # (example address) [0x00406000]&gt

if __name__ == '__main__': packed = open('payload.packed', 'rb').read() unpacked = decompress(packed) open('payload.bin', 'wb').write(unpacked) Running the script produces payload.bin (~13 KB). The file starts with the header again – the packer is nested : the decompressed payload is a second PE executable. 5. Second‑Stage PE – The Real Target file payload.bin # payload.bin: PE32 executable (GUI) Intel 80386, for MS Windows We repeat the same analysis steps on payload.bin . 5.1. Quick string hunt strings -a -n 5 payload.bin | grep -i flag # → No direct flag string, but we see: # "You think this is easy? Think again." 5.2. Import Table inspection r2 -A payload.bin [0x00401000]> iij # The imports are minimal: kernel32.dll (VirtualAlloc, WriteFile, ExitProcess) # No obvious network calls. 5.3. Locate the main routine The entry point ( 0x00401000 ) now points to a standard mainCRTStartup . We follow the call chain:
