Linux memory dump forensics. Attacker obfuscated THEFLAG.txt through 5-step encoding chain (od -t x4, base64, xxd -E -b, tr, GPG), then shredded originals. Solution: extract bash history from RAM to reveal commands and GPG passphrase, reverse each transformation step, handle little-endian byte order from od -t x4.
