Powerful Windows Software Protector

Themida - powerful Windows Software Protector. Designed for software developers who wish to protect their applications against advanced reverse engineering and software cracking.

SecureEngine is an innovating and revolutionary technology for protecting Microsoft Windows applications against modern cracking. Its architecture and design is a completely new idea, never seen before on the security-world.

Themida is a program that helps you to protect your applications against software cracking.

SecureEngine has been designed with a different approach to avoid this common scenario. Its code is running on the same level with the operating system (kernel) with all privileges enabled.

That allows executing any kind of protection technique without being restricted by the operative system. On the other hand, current cracker tools are unable to detect, study and attack protection routines that have designed and implemented to run in the same level (kernel).

Ring0 Technologie - The Windows operative system, OS, architecture is designed to work in two levels of operation: Ring0 runs Windows kernel and device drivers code while Ring3 runs normal applications code.

Ring0 code supervises and controls normal Windows applications that execute in Ring3 level. This means that normal applications are not allowed to run high priority code.

Debugger Guard - DebuggerGuard technology introduces revolutionary techniques to detect a debugger in memory. These techniques cannot be bypassed by any known cracking tools and are almost impossible to bypass even if an attacker knows how they work.

This technology ensures that a protected application can only be run in safe environments, without the presence of debugging tools.

Here are some key features of "Themida":

· Anti-debugger techniques that detect/fool any kind of debugger
· Anti-memory dumpers techniques for any Ring3 and Ring0 dumpers
· Different encryption algorithms and keys in each protected application
· Anti-API scanners techniques that avoids reconstruction of original import table
· Automatic decompilation and scrambling techniques in target application
· Virtual Machine emulation in specific blocks of code
· Advanced Mutator engine
· SDK communication with protection layer
· Anti-disassember techniques for any static and interactive disassemblers
· Multiple polymorphic layers with more than 50.000 permutations
· Advanced API-Wrapping techniques
· Anti-monitors techniques against file and registry monitors
· Random garbage code insertion between real instructions
· Specialized protection threads
· Advanced Threads network communication
· Anti-Memory patching and CRC techniques in target application
· Metamorphic engine to scramble original instructions
· Advanced Entry point protection
· Dynamic encryption in target application
· Anti-tracing code insertion between real instructions
· Advanced Anti-breakpoint manager
· Real time protection in target application
· Compression of target application, resources and protection code
· Anti-"debugger hiders" techniques
· Full mutation in protection code to avoid pattern recognition
· Real-time simulation in target application
