Themida is a secured application compiler and and makes it a protected executable.
What happens normally?
When an application is being created, the Compiler will compile the application source code into several object files made of machine language code. Then the object files are linked together to create the final executable.
What a hacker do?
In the same manner that the source code of an application is converted into machine code at compilation time, there are tools that can convert a compiled application into assembly language or a higher programming language. These tools are known as dissemblers and de-compilers.
An attacker can use a dissembler or de-compiler to study how a specific application works and what a specific routine does. When the attacker has a good knowledge of the target application, he can modify the compiled application to alter his behavior. For example, the attacker could bypass the routine that checks for the trial period in an application and make it run forever or even worse, cause the application to behave as if it was registered.
What is the use of Themida?
Themida® uses the SecureEngine® protection technology that, when running in the highest priority level, implements never seen before protection techniques to protect applications against advanced software cracking.
