Task: 64-bit PIE ELF implementing a table-driven DFA; the right input string drives the machine from state 1 to accepting state 1337, after which it prints the flag. Solution: statically extract the 9-byte transition structs from .rodata, model them as a graph, BFS an accepting path, then run the binary with that input under Docker to let obfuscated_print_the_flag emit the real flag.
