Themida is a software for Windows that shields applications from reverse engineering, cracking and piracy. There are advanced anti-debugging, anti-monitoring and virtualization techniques to secure executable files.
Shield
Users can defend projects against reverse engineering by applying multiple layers of obfuscation, encryption and control flow transformations. The tool significantly distorts the internal logic of executables, making disassembly and static analysis nearly impossible. It is possible to break recognizable code patterns and set traps that confuse debuggers.
Machine
One of the program’s strongest defenses is its virtual machine protection, which executes selected parts of your code in a custom virtual CPU. Such a method creates a completely new instruction set that is unknown to unauthorized analysis. Attackers are forced to reverse-engineer a unique architecture each time, exponentially increasing the time and complexity required to breach the software.
Besides, there are tools that detect and neutralize common debugging components. The list includes OllyDbg, x64dbg and WinDbg. You can monitor memory access, breakpoints and system calls in real time to block intrusion attempts. As for a more basic security product for home usage, you may try Bitdefender.
Features
- executables are encrypted and optionally compressed before distribution;
- users can hide the process from most analysis instruments;
- randomizes the import address table and API calls within protected apps;
- free to download and use;
- compatible with modern Windows versions.
