<h1>What is VMProtect?</h1>
|
||||
|
||||
<p>VMProtect is a new generation of software protection utilities. VMProtect supports
|
||||
Delphi, Borland C Builder, Visual C/C++, Visual Basic
|
||||
(native), Virtual Pascal and XCode compilers. At the same time VMProtect has a built-in
|
||||
disassembler that works with Windows and Mac OS X executables,
|
||||
and also can link a MAP-file created by the compiler to quickly select fragments of code for protection.
|
||||
For easy automation of application protection tasks, VMProtect implements a built-in script language.
|
||||
VMProtect fully supports 32/64-bit operating systems of the Windows family starting from Windows 2000, and Mac OS X starting from version 10.6.
|
||||
Importantly, regardless of the target platform, VMProtect supports all range of executables, that is, the Windows version can work with files from the Mac OS X version and vice versa.</p>
|
||||
|
||||
<p>The cornerstone principle of VMProtect is to provide efficient protection of the application code from
|
||||
examination by making the application code and logic very complex for further analysis and cracking.
|
||||
Main software code protection mechanisms VMProtect applies are: virtualization, mutation, and combined protection that
|
||||
involves mutation of the application code with subsequent virtualization.</p>
|
||||
|
||||
<p>The crucial advantage of the virtualization method used in VMProtect is
|
||||
the fact that the virtual machine executing virtualized fragments of code is embedded into the resulting code of the protected application.
|
||||
Therefore, the app protected with VMProtect needs no third-party libraries or modules to function.
|
||||
VMProtect allows using several different virtual machines to protect different fragments of code of the same application resulting in even more complicated
|
||||
cracking process, because a hacker now has to analyze architecture of multiple virtual machines.
|
||||
</p>
|
||||
|
||||
<p>The method of application code mutation applied in VMProtect is based on obfuscation — a process that adds to the application code
|
||||
various excessive, "garbage" commands, "dead" parts of the code, random conditional jumps.
|
||||
It also mutates original commands and transfers execution of certain operations to the stack.
|
||||
</p>
|
||||
|
||||
<p>The key difference of VMProtect from other software protectors is its ability to protect different parts of the code with different methods:
|
||||
part of the code can be virtualized, the other part is obfuscated and critical fragments are protected using the combined method.</p>
|
||||
|
||||
<p>To prevent false positives from antiviruses the registered version of VMProtect uses the
|
||||
<a href="http://standards.ieee.org/develop/indconn/icsg/taggant.pdf">Taggant</a> library that signs the protected file with a certificate of the license owner.</p>
|
||||
|
||||
<p>Another unique feature of VMProtect is embedding of <a href=
|
||||
"dictionary.htm#Watermarks">watermarks</a> to the code of the application. Watermarks allow to definitely identify the official
|
||||
owner of the hacked copy of the program, and therefore to take certain measures to him or her.</p>
|
||||
|
||||
<p>VMProtect is available in 3 editions:</p>
|
||||
|
||||
<ul>
|
||||
<li>Lite;</li>
|
||||
<li>Professional;</li>
|
||||
<li>Ultimate;</li>
|
||||
</ul>
|
||||
