# Introduction
|
|
|
|
This page contains the steps needed to add additional VMProtect 2 virtual instruction profiles to VMProfiler. Understand that these instructions are for version 1.8 and may be different in later versions.
|
|
|
|
# Example - Existing Profile
|
|
|
|
Consider the `ADDQ` profile which is displayed below which can be found inside of `add.cpp`
|
|
|
|
```cpp
|
|
vm::handler::profile_t addq = {
|
|
// ADD [RBP+8], RAX
|
|
// PUSHFQ
|
|
// POP [RBP]
|
|
"ADDQ",
|
|
ADDQ,
|
|
NULL,
|
|
{ { // ADD [RBP+8], RAX
|
|
[]( const zydis_decoded_instr_t &instr ) -> bool {
|
|
return instr.mnemonic == ZYDIS_MNEMONIC_ADD && instr.operands[ 0 ].type == ZYDIS_OPERAND_TYPE_MEMORY &&
|
|
instr.operands[ 0 ].mem.base == ZYDIS_REGISTER_RBP &&
|
|
instr.operands[ 0 ].mem.disp.value == 0x8 &&
|
|
instr.operands[ 1 ].type == ZYDIS_OPERAND_TYPE_REGISTER &&
|
|
instr.operands[ 1 ].reg.value == ZYDIS_REGISTER_RAX;
|
|
},
|
|
// PUSHFQ
|
|
[]( const zydis_decoded_instr_t &instr ) -> bool { return instr.mnemonic == ZYDIS_MNEMONIC_PUSHFQ; },
|
|
// POP [RBP]
|
|
[]( const zydis_decoded_instr_t &instr ) -> bool {
|
|
return instr.mnemonic == ZYDIS_MNEMONIC_POP && instr.operands[ 0 ].type == ZYDIS_OPERAND_TYPE_MEMORY &&
|
|
instr.operands[ 0 ].mem.base == ZYDIS_REGISTER_RBP;
|
|
} } } };
|
|
