How to crack the InstallShield installation package

Note:

(1) InstallShield decompiler is ISD

(2) try sid.

Today, biweilun issued his own cracking notes. In fact, it has been a long time in his arms to teach you how to crack the InstallShield installation package and obtain the installation serial number.

Currently, the InstallShield installation package is widely used. Many software packages are packaged using this software. It has its own script language, the installation script for installation packages of 5.x 6.x 7.x is usually setup. INS andSetup. RebootIt is explained by ikernel.exe. Ikernel.exe is the interpretation engine located in c: \ Program Files \ common files \ InstallShield \ engine \ 6 \ intel
32. You can perform dynamic debugging under this directory to break the breakpoint.

[1] If there is only one exe program in the installation file, you only need to enter the installation password without the user name. The serial number in the installation package is fixed, the sequence column number is not generated based on the user name, so there is no algorithm in the middle. You can use a software on the DOS interface to directly obtain the installed password. The software name is InstallShield packagefortheweb password cracker.

The syntax format is ispftw.exe test.exe, which is the installation package to be cracked.

[2] the installation of a program is a directory. If there is a setup. INS file in it, the version of this installation package is not very high. There may be an algorithm in this script file, which is actually very simple. Remove this setup. the read-only and hidden attributes of the INS file can be directly loaded using Windows InstallShield decompile to obtain the source code of the script. This is a decompilation software.

[3] If the script isSetup. RebootIt indicates that the version is relatively high, which is produced by 6.x and 7.x. This is basically used now. You can use InstallShield decompiler and InstallShield 6/7 script decompiler to decompile the source code. InstallShield decompiler is a DOS window, which can be output to view the source code. InstallShield 6/7 script decompiler is a graphical interface and can edit the operator. However, it does not support Chinese characters well.

ThereforeSetup. RebootIn general, we first use InstallShield decompiler to export the script source code, get the correct Chinese information, and write down the offset address and machine code. Run InstallShield 6/7 script decompiler to open the script file and compile and modify the file according to the obtained offset address.

The InstallShield decompiler syntax is isd.exeSetup. RebootOutput a TXT file containing the script source code isd_dec.txt

Then, find sensitive information such as "serial number error" in the TXT file. You can see the offset address before, and write it down to InstallShield 6/7 script decompiler to modify the script. Now there is no example to explain, it's boring.

If an instance is available in the future, we will show you how to crack it, which is easier to use in actual operations.
