Themida Advanced Windows Software Protection System

Understand the risks

When developing an application, the compiler compiles the application's source code into multiple object files composed of machine language code. Subsequently, these target files will be linked together to form the final executable file.

Just as the source code of an application is converted into machine code during compilation, there are also tools that can convert compiled applications into assembly language or higher-level programming languages. These tools are called disassemblers and decompilers.

Attackers can use disassemblers or decompilers to study the working principles of specific applications and the functionality of specific routines. Once the attacker has a thorough understanding of the target application, they can modify the compiled application to alter its behavior. For example, attackers can bypass the routine that checks the trial period of an application, making it run permanently, or even worse, making the application appear as if it is already registered.

Software Protector

The emergence of software protectors aims to prevent attackers from directly inspecting or modifying compiled applications. Software protectors are like shields, encrypting and protecting applications from potential attacks. When a protected application is to be run by the operating system, the software protector will first control the CPU and check if any possible cracking tools (disassemblers or decompilers) are running on the system. If everything is safe, the software protector will start decrypting the protected application and hand over control to the CPU to make it run as normal.

The advantages of using software protectors include:

1. Protect applications from piracy infringement.
2. Prevent attackers from researching the implementation methods of applications.
3. Attackers are not allowed to modify the application to alter its behavior.

weakness

Since the birth of software protectors, many attackers have focused most of their efforts on attacking the software protector itself rather than the application. Many tools have been developed to assist in attacking software protectors. These attacks typically result in attackers obtaining the decrypted and unprotected original application.

The main issue with software protectors is that the protection techniques they use are well-known to crackers, so they can be easily bypassed using traditional cracking tools. Another important issue with software protectors is that they are restricted by the operating system to run with normal application privileges. Therefore, attackers can use cracking tools that run at the same priority as the operating system to fully monitor the behavior of software protectors at specific times and launch attacks at specific locations.

Revolutionary solution

With Themida ®， We focus on the main weaknesses of software protectors, providing a comprehensive solution to overcome these issues. Themida ® Using SecureEngine ® Protection technology, implementing unprecedented protection measures at the highest priority to protect applications from advanced software cracking.

SecureEngine ® Defeated all current cracking tools available for attacking protected applications and ensured that protected applications only run in a secure environment.

The current protector claims to be professional!

Software protection programming is not a very familiar field for most programmers. Software protection technology cannot be seen and compared like "visible" features. Therefore, most software protection authors will talk about the impressive techniques contained deep within the protection scheme, but many times, these techniques are almost non-existent or much simpler than they seem. Most software protectors repeatedly emphasize the use of very powerful encryption algorithms such as RSA, elliptic curves, and AES, hoping that end users will believe that these protectors and encryption algorithms are unbreakable. However, this is far from the truth, as software protection is very different from data protection. Even if software protectors use the most powerful encryption algorithms to encrypt protected applications, sooner or later they will need to decrypt the protected applications in order for the CPU to run them. It is at this stage that most attackers will start working, dumping decrypted applications from memory to disk, thus eliminating the need to process encryption algorithms and rebuild the original application.

mission

In Themida ®， We hope to take a realistic view of the weaknesses that attackers can exploit, as well as the content that we truly need to pay attention to when protecting applications, in order to provide the highest level of security protection and prevent software cracking.
