Task: Binary that allocates a 16-byte name buffer and an adjacent 8-byte check structure on the heap, reading 100 bytes into the name. Solution: Overflowed the heap buffer with 36 bytes of padding to reach the check structure's field2, then wrote 0xdeadbeef to pass the magic value comparison and trigger flag printing.
