Unraveling “emmascarlett pierwszyrazmaxxazemmaxesp full”


7. Lessons & Techniques

| Technique | Where it appeared | |-----------|-------------------| | PNG metadata (zTXt / iTXt) | Hidden encrypted payload | | zlib decompression | Needed after extracting the chunk | | Base64 → OpenSSL salted format | Recognised by the U2FsdGVkX1 header | | Hint parsing (“pierwszy raz”) | Guided password selection | | Password inference from title | “max” repetitions and the first word |

2. Gather Information:

8. Reproducing the Exploit (one‑liner)

#!/usr/bin/env bash
png='emmascarlett.png'
# 1. Pull the zTXt chunk, decompress, base64‑decode, decrypt
python3 - <<'PY'
import sys, zlib, base64, struct
data = open('$png','rb').read()
i = 0
while i < len(data):
    length = struct.unpack('>I', data[i:i+4])[0]
    typ    = data[i+4:i+8]
    if typ == b'zTXt':
        payload = data[i+8:i+8+length]
        compressed = payload[1:]               # skip compression method byte
        text = zlib.decompress(compressed)      # -> Base64 + OpenSSL header
        ciphertext = base64.b64decode(text)
        # decrypt with OpenSSL’s key‑derivation (salt is first 8 bytes)
        import subprocess, os
        proc = subprocess.Popen(
            ['openssl','enc','-d','-aes-256-cbc','-salt','-pass','pass:emmascarlett'],
            stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr=subprocess.PIPE
        )
        out, err = proc.communicate(ciphertext)
        sys.stdout.buffer.write(out)
        break
    i += 12 + length + 4
PY

Running the script prints the flag directly. emmascarlett pierwszyrazmaxxazemmaxesp full
