hi everybody
everyone knows cracking in windows. but cracking programs under linux ... somehow impossible without right knowledge.
there is a game out there ... which has a stupid handbook-page/2letters protection. so ... i guess softice doesn't work under linux ... 
it's a statically linked file ... how do i disassembly it first and then debug it step by step?
(NO, GDB DOES WORK SHIT HERE)  |

yes gdb sucks for re but is still usable, try strace, it will show you how syscalls are called in a clean way, the other think you can do is disassemble the file, try Bastard, or more simple stuff like HT, objdump maybe... |

the only one i got working now is ldasm. all other pograms didn't want to compile (because of severail things, i guess my amd64 arch is problem #1), but also the compiled programs i downloaded didn't want to work. (missing own libs and stuff)
argh
anway ... what is HT? |

mhm
i tried strace ... but it does not get any output itself from the program. perhaps the coders used a workaround to hide their code from beeing traced by such simple standard linux tools.
| Quote: | execve("./program.bin.x86", ["program.bin.x86"], [/* XX vars */]) = 0
--- SIGTERM (Terminated) @ 0 (0) ---
PROGRAM OUTPUT BLA BLA BLA

HT is an editor and disassembler that suports, ELF, PE, etc
try strace -f
If still doesn't work is becuase there is some ant-dbg trick, like using ptrace or sending itself a sigtrap. |

strace -f didn't even helped in that case.
but objdump -d is doing a good job so far. |
