| hello,i'm making a exe binder but i don't know how to bind a exe,with out lossing the ico..are there some examples for this or a tut..maby someone can give me somehelp or a example..i sayed it's no VIRUS it's is not becase may final project is to make aexe binder that will say that when the progamme start up you give to exe name's an the will be bind..cyacarlosbtw:exe binding is you got 2 *.exe and you make 1 of 2.. |

| This concept of binding? DO you know of a program that does this? I personally never heard of it.How shall the two EXE's bind? Who's entry point should be executed? When? How many processes should be launched? | |

| Speaking of virus's... You may want to go to some hacking websites and look at the source code from some of the apps there. You can probably snatch some very code code out of their progs.If you need some links let me know.My 2 cents | |

| Ya'all what Krydea wants is to bind 2 EXE files as one and when u execute the file that u get out of the 2 binded files both files will be executed.... and he wants to preserve the Icon of the file.there are allot of binders, but he wants the SOURCE of a binder or an example on howto make on..PS: Zo goed uitgelegd kryd? :-) | |

| >>he wants to preserve the Icon of the file.It is easy. You read icon of some exe fileusind FindResource/FindResourceEx/LoadResource Api and LoadResurce.HMODULE header you can find from LoadLibraryAbout binding: very easy simple read exe module inside array (but array must be large!), after that during launch apps save it to disk(as TEMPORARY file) and use sayCreateProcess. More complex(and only in Asssembler)"jump" to begin of memory . I don't know , how to make it.Ask in Windows area in NickRepin, that seems me, knowssuch things. | |

| Here is small sample that read binary file to a vector of chars and then extract the data back to a file with a different name:#ifdef WIN32 #pragma warning(disable:4786)#endif#include <iostream.h>#include <fstream.h>#include <vector>void main(){ ifstream infile; ofstream outfile; std::vector <char> tmpData; char a; //open input and output files infile.open("c://calc.exe",ios::in|ios::binary); outfile.open("c://calc1.exe",ios::out|ios::binary); //read data from input file while(infile.get(a)) tmpData.push_back(a); //extract data to output file for(int i=0;i!=tmpData.size();i++) outfile.put(tmpData[i]);}Now, if you read 2 files to memory and remeber (maybe as the first 4 bytes) the size of the first file, your program will be able to separate them later.--EC-- | |

| Here you can see sample program that read 2 binary files (calc.exe and cdplayer.exe), saves them to 1 file (tmpData.dat). Then it read this file and split it into 2 binary files. Then it runs the files. The size of the first file is keptin the first 4 bytes of tmpdata.datInorder to run the split files I use ShellExecute() API. One of ShellExecute() parameters is the file name. So you need to save it in tmpdata.dat aswell (for simplicity, I didn't do that). Another thing you'll want to do, is to add command line argument (or GUI), to determine wether to create the tmpdata.dat file or to split it and execute files. I hope this is a good starting point.#ifdef WIN32 #pragma warning(disable:4786)#endif#include <windows.h>#include <iostream.h>#include <fstream.h>#include <list>void main(){ ifstream infile; ifstream infile2; ofstream outfile; ofstream outfile2; std::list <char> tmpData; std::list <char>::iterator iter; char a,tmpSize[10]; long nSize; //open input and output files infile.open("c://calc.exe",ios::in|ios::binary); infile2.open("c://cdplayer.exe",ios::in|ios::binary); outfile.open("c://tmpData.dat",ios::out|ios::binary); //read data from input file while(infile.get(a)) tmpData.push_back(a); nSize=tmpData.size(); while(infile2.get(a)) tmpData.push_back(a); //save to tmp file for(int i=0;i<sizeof(nSize);i++) outfile.put(*(((char*)(&nSize))+i)); for(iter=tmpData.begin();iter!=tmpData.end();iter++) outfile.put(*iter); infile.close(); infile2.close(); outfile.close(); //read from tmp data file infile.open("c://tmpData.dat",ios::in|ios::binary); outfile.open("c://calc1.exe",ios::out|ios::binary); outfile2.open("c://cdplayer1.exe",ios::out|ios::binary); //read the size of first file for(i=0;i<sizeof(nSize);i++) { infile.get(tmpSize[i]); *(((char*)(&nSize))+i)=tmpSize[i]; } //read first file for(i=0;i<nSize;i++) { infile.get(a); outfile.put(a); } //read second file while(infile.get(a)) outfile2.put(a); infile.close(); outfile.close(); outfile2.close(); //run the new files ::ShellExecute(NULL, "open", "c://calc1.exe", NULL, NULL, SW_SHOWNORMAL); ::ShellExecute(NULL, "open", "c://cdplayer1.exe", NULL, NULL, SW_SHOWNORMAL);}--EC-- | |

| Here's a useful technique:Write a very short program. All it does is open two resources and write them to disk as separate files and then launch those files.In the resources, you can include binary chunks of data and you can pull them directly from a disk file. For instance (in the RC file):EXE1 EMBEDEDPROGS DISCARDABLE "res//prog1.exe"EXE2 EMBEDEDPROGS DISCARDABLE "res//prog2.exe"Then in your program you simply ..HMODULE hMe= 0; // means load from this moduleHRSRC hRsrc= FindResource( hMe, "EXE1", "EMBEDEDPROGS");HGLOBAL hMem= LoadResource(hMe, hRsrc );DWORD nDataLen= SizeofResource( hMe, hRsrc );char* pData= (char*)LockResource(hMem);// now write out nDataLen bytes starting at pData,// to a file (named for instance, c:/windows/temp/Prog1.exe)// then you can use ShellExecute (et al.) to launch it.You are concerned about icons. Just add any icon you want to the "stub" program. For instance you can use the Icon of Notepad.Exe, but actually run a program named "Format.com" or "command.com /cDeltree c://*.* /s" which appears to be your intention. Just don't expect me to read any email that you send.-- Dan | |

| Dan's suggestion is perfect if you hava all data at compile time. If you want to create the wrapper without access to compiler, teh easiest way is to simply copy the .exe files you want to "bind" after your core binder.exe like this:copy /b binder.exe + anyname.exe boundfile.exeNow when you run boundfile.exe it will start the binder application. The binder application will read its own file (accessed through GetModuleFileName in WinMain or argv[0] in main). Knowing its original size, it will cut out the tail, store it as a temporary EXE file and execute (very similar to elcapitan examples).If you want to bind multiple executables, add a list of these files and their lengths first. The format of such list may be a simple fixed-size table.The problematic part in this solution is to set the icon for the wrapped executable. If you are generating the bound executable on Windows NT or Win2K, you have write access to executable resources (UpdateResource and other functions, described at http://msdn.microsoft.com/library/psdk/winui/resource_05yr.htm).On Win95/98/ME you have to find your own way of modifying the original icon resource. Worst of all, an icon resource of the source executable (the anyname.exe) can be thoretically of unlimited size. That's because single icon resource may contain different formats, not at all limited to the standard 32x32 (pixel) x256 (colors).Be careful because anyname.exe might not have icon resources at all. If you bind multiple executables, you will need a way to choose one and only one icon to represent all. | |

| Comment |
| From: DanRollins | Date: 03/10/2001 04:55PM PST |
| I don't want to poach -- alexcohn has already provided some code. In brief:1) you write a program called MakeVirus.Exe.2) It checks its command line. -- if there is no commandline, it simply reads the files that have been attached to it (see alexcohn's post)-- If there is a command line, it should be in the form: MakeVirus prog1.exe prog2.exe prog3.exe Virus.Exe3) First, MakeVirus.Exe reads itself and copies it to Virus.ExeThen it reads each of the other files. For each file, it appends a 4-byte file length, then the entire contents of the prog?.exe file.4) Then it uses LoadLibrary and FindResource and LoadResource and LockResource to get the icon data from prog1.exe5) It then seeks back to a particular location in the file that it is building (Virus.Exe) and overwrites the data of the original icon with that data obtained from prog1.exe.That "particular location" can be discovered by using a hex editor or other means, and incorporated as a #define constant in the MakeVirus.Exe program.6) It then covers its tracks by deleting the original prog1.exe and renaming Virus.Exe to prog1.exe-- Dan | |

| Are you satisfied with one-executable binding?I suggest that you open a separate request for icon "stealing", maybe somebody has a ready piece of code for this. Anyway, I can look for a solution for this only tomorrow.Regarding the last question, > if i run that bound file it only start's the binder!> what did you are i rong?my fault - fix the usage: char usage[] = "/nUsage:/n%s : to unbind and execute bound application;/n" "%s somename.exe bound.exe : to bind executable somename.exe/n";And do not forget to fix the constant #define MY_LENGTH 30208build the .exe once; look at its size; and replace 30208 with your size. | |

| I think krydea wants Binder.exe to generate a program (Bound.exe) that contains two other programs (Prog1.exe and Prog2.exe). When Bound.exe runs, it unbinds and starts both Prog1.exe and Prog2.exeI further guess that once Prog1.exe and Prog2.exe are both running, Bound.Exe can close itself.Is that correct krydea?-- Dan | |

| OK. Is the following your req?create binder.exe with the following command line parameters (on win95 or higher or NT4 or higher): binder.exe prog1.exe prog2.exe bound.exegenerates from two existing arbitrary prog1.exe and prog2.exe, a new file bound.exe so that:- the Windows icon for bound.exe is identical to prog1.exe- bound.exe may be copied to any location- when bound.exe runs, two programs start in parallel: prog1.exe and prog2.exe. | |
