Are you looking for an unpacker is what you mean?

what's ninja? PENinja? why it's fake?

If I recall correctly its a packer.

nezumi		October 15, 2007 17:14.07 CDT
yes, actually it's a packer http://www.exetools.com/files/protectors/win/peninja.zip and I can't unpack this s... well, this stuff, since it doesn't work at all. see, I wrote follow code: main() { printf("hello,world!\n"); } compiled it with ms vc 6.0, packed it with peninja, ran exe and got an exception. does anybody have correctly packed file for analyze?

PeNinja is an old packer mr Kris Kaspersky hehe... it ain't targeted at Win2k++, just win9x only. Try to run it under VMWARE stuffs like else try to correct the _exception_ by yourself hehe..

any program that uses os-specific methods _must_ check os version.

I used RDG and it told me that my target is crypted with fake ninja 2.0 :) Maybe rdg is not correct... PS: the actual name is "fake ninja" according to rdg

sovietskicpu		October 15, 2007 18:18.51 CDT
what do you mean kris ? it is just a packer not a commercial software, it is not supposed that the packer author will check for the os version.

> bodzcount: PS: the actual name is "fake ninja" according to rdg hehe better saying RDG is fake PEID like tool hehe...

nezumi		October 15, 2007 18:31.16 CDT

iirc the peninja itself is packed with itself (not sure but it is packed and i assume any self respecting authour to use his own product on himself first anyway the ep is for peninja itself is here 00401581 PUSH 0 ; /pModule = NULL 00401583 CALL peninja.004016F3 ; \GetModuleHandleA 00401588 MOV DWORD PTR DS:[404018],EAX 0040158D PUSH 0 ; /lParam = NULL 0040158F PUSH peninja.004015AE ; \|DlgProc = peninja.004015AE 00401594 PUSH 0 ; \|hOwner = NULL 00401596 PUSH 3E2 ; \|pTemplate = 3E2 0040159B PUSH DWORD PTR DS:[404018] ; \|hInst = NULL 004015A1 CALL peninja.0040171D ; \DialogBoxParamA 004015A6 PUSH 0 ; /ExitCode = 0 004015A8 CALL peninja.004016FF ; \ExitProcess 004015AD RETN and it probaly crashes here 00401407 \|. 0FB758 0C \|MOVZX EBX,WORD PTR DS:[EAX+C] didnt check much but i had a crash whn i tried to pack so loaded peninja itself and tried to see where it crashes
