힙 명령어 출력에 대한 간단한 설명
각 줄은 malloc 청크에 해당하며, 힙 함수(free, malloc, realloc, calloc)가 실행될 때마다 힙이 덤프됩니다.
addr: malloc 청크의 실제 주소
usr_addr: malloc 함수가 사용자에게 반환하는 주소
size: malloc 청크의 크기
flags: P는 PREV_INUSE, M은 IS_MAPED, A는 NON_MAIN_ARENA
기본 가젯 검색
rop-tool gadget ./program
AT&T 구문으로 모든 가젯 표시
rop-tool gadget ./program -f att -a
RAW x86 파일에서 가젯 검색
rop-tool gadget ./program -A x86
바이너리에서 '분할된' 문자열 검색
rop-tool search ./program -s "/bin/sh"
바이너리에서 모든 문자열 검색
rop-tool search ./program -a
오프셋 0x1000에서 바이너리 패치, "\xaa\xbb\xcc\xdd"로 작성하고 "patched"로 저장:
rop-tool patch ./program -o 0x1000 -b "\xaa\xbb\xcc\xdd" -O patched
/bin/ls 명령의 힙 할당 시각화:
rop-tool heap /bin/ls
주소 0x08048452에서 0x100 바이트 디스어셈블
rop-tool dis /bin/ls -l 0x100 -a 0x08048452
rop-tool gadget /bin/ls
rop-tool search /bin/ls -a
rop-tool search /bin/ls -s "/bin/sh\x00"
rop-tool heap ./a.out
rop-tool dis ./bin # Many formats
