Themida is an advanced Microsoft Windows software protection system designed for software developers who want to protect their programs from advanced reverse engineering to prevent decompilation and hacker software cracking.

Specific functions:

Understanding risks

After a program is created, the compiler will compile the original code of the program into several machine code files. Next, these files will be linked up to generate the final software file.

Similar to the program's original code being converted to machine code during compilation, some tools can also convert files compiled into machine code into assembly languages or more advanced programming languages. These tools are called anti-assembler and anti-compiler.

A software cracker can use the reassembler or the recompiler to observe how a specific program operates and the functions of a specific routine. When a software hacker has a good understanding of the target program, he can modify the operation mode of the program. For example, a software cracker can enable a program to bypass a routine that checks the program's probation period, making it always start or worse, making the program operate like it has already been registered.

Software Protection Layer

The existence of the software protection layer prevents the software cracker from directly detecting or modifying compiled programs. The software encryption protection layer is like a shield, which encrypts and protects the program without cracking. When a protected program is about to be started by the operating system, the software protection layer first controls the CPU and checks whether there is a reassembler or a recompiler running in the system. When no program is running abnormally, the software protection layer decrypts the protected program and returns the CPU control to make it operate normally.

Benefits of using the software protection layer include:

    • Protection programs are not pirated
    • This prevents the software cracker from detecting how the program works.
    • Do not allow the software cracker to modify the program Operation Mode

Weakness

Since the existence of the software protection layer, many software crackers spend most of their energy and time cracking the software protection layer, instead of being protected. Many tools are developed to help crack the software protection layer. These attacks usually allow the software cracker to remove the protective layer and obtain the original program.

The biggest problem with the software protection layer is that the protection methods they use are already familiar to hackers, so they can easily bypass the software protection layer by using traditional hacking tools.

Another problem with the software protection layer is that their operations are limited by operating systems. In other words, they only work in normal mode. Therefore, software crackers can use any hacker tool that runs at the same priority level as the operating system, this allows these hacking tools to fully monitor the operation of the software protection layer at a specific time and then launch attacks in a specific place.

Revolutionary solution

The main weakness of the themida software protection layer enables it to provide a complete solution to these problems. Themida®Use secureengine®Protection Technology. When it runs at the highest priority level, it uses defense technologies that have never been used to combat advanced software cracking.

Secureengine®It can beat all existing cracking tools used to crack protected software. Therefore, it ensures that your protected software only works in a secure environment.

The current protective layer claims they are the best!

Software protection programming has always been a field unfamiliar to most programmers. Software Protection technologies are not as visible as they are, and cannot be compared. Therefore, most software protection program authors can describe many impressive protection measures and technologies, but in most cases these protection measures and technologies are hard to exist, or easier than what they describe. .

Most software protection layers emphasize very strong encryption algorithms, such as RSA, elliptic curves and AES. They hope that the ultimate users will be able to believe that the software protection layer and Encryption Algorithm functions are effective and cannot be cracked. However, this is not the case because the protection software and data protection are very different. Even if the software protection layer uses the most robust encryption algorithm to encrypt the program, the program will need to be decrypted sooner or later so that it can run on the CPU. Most software Crackers will start the decryption phase and transfer the decrypted program from the memory to the disk, so that they do not need to crack these encryption programs to obtain the original program.

Task

Themida®We are actually targeting some vulnerabilities that can be exploited by software hackers, in order to provide as much protection as possible to any program.
