.NET cracking tut or hints ?
Have you seen one ? What tools are used to debug .NET apps ?
What's the best approach ? Thanx in advance bye |
nobody ? ever ?
OK, different question :
I've got the code dissassembled into IL, I found my piece I was looking for, but now what ? Is there a way to debug it, or what other tools are needed ? If I have IL like this : IL_001f: call string [Idxx]xxx.Lib.Misc.Idxx::GetSerial(string) IL_0024: callvirt instance string [mscorlib]System.String::ToUpper() IL_0029: stloc.2 IL_002a: ldarg.0 IL_002b: ldstr "edSer" IL_0030: call instance string [CtlLib]xxx.Lib.CtlLib.SomeControl::GetInput_Value(string) IL_0035: stloc.3 IL_0036: ldloc.2 IL_0037: ldloc.3 IL_0038: callvirt instance bool [mscorlib]System.String::Equals(string) IL_003d: ret how can I "sniff" what values are compared ? How can I found, where exactly are those instructions ? Is there a breakpoint (symbols ?) to set in SIce , or it can be debugged in some other tool ? And another question : can I "rip" some function (I mean REAL asm code, not some pseudocode) from .net dll ? Or call that function from dll from my non-.NET app ? Thank you very much bye |
re
Thank you for answering.
Actually - most of tools you named, are so called OBFUSCATORS, which (if I understand them right) just somehow 'scramble' or rename metadata and all names there - so they are harder to disassemble and understand. They are something like packers or protectors for 'normal' PE files... What I needed was decompiler for IL, or some tool to 'relate' IL code produced by ILDasm and REAL (I mean executed) code in CLR, because IL is just some kind of p-code.... One decompiler you mentioned is Anakrino, but I couldn't make that one work :( It just starts ... and ends. No gui, nothing. But I already solved my problem different way - I learned MSIL and have rewritten needed function in classical C. Anyway, if somebody knows, how to debug IL, or how to patch it, or use it with non-.NET app, any info is welcome ... bye |
