Task: APFS disk image with 500,000 identical key files, one needed to decrypt flag (PBKDF2 140M iterations makes bruteforce impossible). Solution: Detected anomalous file via APFS inode metadata (write_generation_counter, total_bytes_written, mtime vs btime), recovered original key from freed block using APFS Copy-On-Write forensics.
