Task: a nested reverse matryoshka starts with a damaged UPX-packed Rust ELF and unfolds through Go, Python bytecode, an x86-64 ELF, and a final Android AArch64 ELF. Solution: repair the packer, invert each checker, dump hidden payloads from memory, ignore fake flag bait, and continue to the last ARM stage for the real CODEBY flag.
