Dnguard Hvm — Unpacker
DNGuard injects a native execution engine (typically a companion DLL like HVMRuntm.dll or embedded native code) into the .NET process. This engine hooks into the .NET Common Language Runtime (CLR), specifically targeting the JIT compiler engine ( clrjit.dll ). Method Body Encryption and Virtualization
: Reconstruct the original MSIL (Microsoft Intermediate Language). DNGuard often uses custom VM opcodes; a full-featured unpacker needs a mapper to translate these back to standard .NET instructions.
Used to dump modules directly from native memory after DNGuard has initialized its runtime components. Dnguard Hvm Unpacker

While the protected program is running, unpackers execute it to dump the decrypted code directly from memory (the Module from Memory) along with the runtime library (e.g., Runtime.dll ) that DNGuard uses for its HVM.
