The most innovative aspect of DNGuard is its HVM (High-Level Virtual Machine) technology. Traditional .NET protectors might encrypt the entire assembly and decrypt it into memory, making it vulnerable to memory dumping tools like Process Dumper. DNGuard HVM, however, takes a different approach:
The protected executable is run, and the unpacker's hooking module intercepts critical runtime functions (like JIT compilation). This bypasses integrity checks and prevents tamper alerts. A key advantage of some unpackers is their ability to function even after a DNGuard trial version has expired. Dnguard Hvm Unpacker
