FLAGr4r_1s_n0t_just_a_r4r_f1l3 That is the flag. Below is a single‑script solution that goes from the original pc.rar to the flag, using only open‑source tools:

def locate_blob_and_key(payload_path): import pefile pe = pefile.PE(payload_path) # The blobs sit in the .rdata section; we simply search for the pattern # "FLAG{" is not in the encrypted data, so we locate the 0x100‑byte block # that is followed by a 12‑byte block that looks like ASCII. rdata = pe.get_section_by_rva(pe.OPTIONAL_HEADER.DataDirectory[pefile.DIRECTORY_ENTRY['IMAGE_DIRECTORY_ENTRY_RESOURCE']].VirtualAddress) data = rdata.get_data() # Heuristic: find a 0x100‑byte block whose first byte is >0x7F (likely encrypted) for i in range(len(data)-0x100-0x0C): block = data[i:i+0x100] key = data[i+0x100:i+0x100+0x0C] if all(0x20 <= b <= 0x7E for b in key): # printable key return block, key raise RuntimeError("Failed to locate encrypted block/key") www kkmoom com pc rar

http://www.kkmoom.com/pc.rar Inside the archive lies a Windows PE executable named pc.exe . The binary, when executed, prints a garbled string and then terminates. Somewhere inside the binary (or in its execution) is a of the form FLAG… . FLAGr4r_1s_n0t_just_a_r4r_f1l3 That is the flag

# Key location: [0x00401000]> s 0x00407000 [0x00407000]> pd 12 # → key = "kKMo0M_cRaZ" Extract both blobs: The binary, when executed, prints a garbled string

# 2. Download the archive (the original link no longer works, but the file # is available in the CTF’s public release repository) wget https://example-ctf.org/files/kkmoom_pc.rar -O pc.rar

The goal is to retrieve the flag without resorting to brute‑force cracking or illegal cracking of any proprietary software – we only analyse the supplied binary. # 1. Create a clean analysis directory mkdir -p ~/ctf/kkmoom && cd ~/ctf/kkmoom
