# Theodosius - Jit linker, Mapper, Mutator, and Obfuscator
|
|
||||||
|
|
||||||
Theodosius (Theo for short) is a jit linker created entirely for obfuscation and mutation of both code, and code flow. The project is extremely modular in design and supports
|
|
||||||
both kernel and usermode projects. Since Theo inherits HMDM (highly modular driver mapper), any vulnerable driver that exposes arbitrary MSR writes, or physical memory read/write can be used with this framework to map unsigned code into the kernel. This is possible since HMDM inherits VDM (vulnerable driver manipulation), and MSREXEC (elevation of arbitrary MSR writes to kernel execution).
|
|
||||||
|
|
||||||
Theo can be used for many projects. The modularity of the code allows for a programmer to use this framework however they please. A few example usages of Theo would be, streaming code and data from a .lib over a network directly into memory, resolving unexported symbols via PDB, allocating each instruction of a function inside of code caves, and much more.

## Linking - Dynamic And Static
|
|
||||||
|
|
||||||
#### What Is A Linker
|
|
||||||
|
|
||||||
A linker is a program which takes object files produces by a compiler and generates a final executable native to the operating system. A linker interfaces with not only object files but also static libraries, "lib" files. What is a "lib" file? Well a lib file is just an archive of obj's. You can invision it as a zip/rar without any compression, just concatination of said object files.
|
|
||||||
|
|
||||||
Theo is a jit linker, which means it will link objs together and map them into memory all at once. For usability however, instead of handling object files, Theo can parse entire lib files and extract the objects out of the lib.
|
|
||||||
|
|
||||||
#### Object Files
|
|
||||||
|
|
||||||
If you define a c++ file called "main.cpp" the compiler will generate an object file by the name of "main.obj". When you refer to data or code defined in another c/c++ file, the linker uses a symbol table to resolve the address of said code/data. In this situation I am the linker and I resolve all of your symbols :).
|
|
||||||
|
|
||||||
#### Static Linking
|
|
||||||
|
|
||||||
Static linking is when the linker links entire routines not created by you, into your code. Say `memcpy` (if its not inlined), will be staticlly linked with the CRT. Static linking also allows for your code to be more independant as all the code you need you bring with you. However, with Theo, you cannot link static libraries which are not compiled with `mcmodel=large`. Theo supports actual static linking, in other words, using multiple static libraries at the same time.
|
|
||||||
|
|
||||||
#### Dynamic Linking
|
|
||||||
|
|
||||||
Dynamic linking is when external symbols are resolved at runtime. This is done by imports and exports in DLL's (dynamiclly linked libraries). Theo supports "dynamic linking", or in better terms, linking against exported routines. You can see examples of this inside of both usermode and kernelmode examples.

# Usage - Using Theodosius
|
|
||||||
|
|
||||||
## Integrating Clang
|
|
||||||
|
|
||||||
For integration with visual studios please open install [llvm2019](https://marketplace.visualstudio.com/items?itemName=MarekAniola.mangh-llvm2019) extension, or [llvm2017](https://marketplace.visualstudio.com/items?itemName=LLVMExtensions.llvm-toolchain) extension. Once installed, create or open a visual studio project which you want to use with LLVM-Obfuscator and Theo. Open ***Properties*** --> ***Configuration Properties*** ---> ***General***, then set ***Platform Toolset*** to ***LLVM***.
|
|
||||||
|
|
||||||
Once LLVM is selected, under the ***LLVM*** tab change the clang-cl location to the place where you extracted [clang-cl.rar](https://githacks.org/_xeroxz/theodosius/-/blob/cc9496ccceba3d1f0916859ddb2583be9362c908/resources/clang-cl.rar). Finally under ***Additional Compiler Options*** (same LLVM tab), set the following: `-Xclang -std=c++1z -Xclang -mcode-model -Xclang large -Xclang -fno-jump-tables -mllvm -split -mllvm -split_num=4 -mllvm -sub_loop=4`.
|
|
||||||
|
|
||||||
Please refer to the [LLVM-Obfuscator Wiki](https://github.com/obfuscator-llvm/obfuscator/wiki) for more information on commandline arguments.
|
|
||||||
|
|
||||||
#### Requirements
|
|
||||||
|
|
||||||
* No SEH support, do not add `__try/__except` in your code.
|
|
||||||
* No CFG (control flow guard) support. Please disable this in C/C++ ---> Code Generation ---> Control Flow Guard
|
|
||||||
* No Stack Security Check Support. Please disablel this in C/C++ ---> Code Generation ---> Security Check (/GS-)
|
|
||||||
* Your project must be set to produce a .lib file.
|
|
||||||
* Your project must not link with other static libraries which are not compiled with `-Xclang -mcmodel-large`.
|
|
||||||
* Project must be compiled with the following flags
|
|
||||||
* `-Xclang -mcmodel=large`, removes RIP relative addressing besides JCC's.
|
|
||||||
* `-Xclang -fno-jump-tables`, removes jump tables created by switch cases.
|
|
||||||
* `/Zc:threadSafeInit-`, static will not use TLS (thread local storage).
|
|
||||||
|
|
||||||
## Lambdas For Explicit Constructor
|
|
||||||
|
|
||||||
Theodosius uses the same class structure as HMDM does. Its a highly modular format which allows for extreme usage, supporting almost every idea one might have. In order to use Theo, you must first define three lambdas, `theo::memcpy_t` a method of copying memory, `theo::malloc_t` a method to allocate executable memory, and lastely `theo::resolve_symbol_t` a lamdba to resolve external symbols.
|
|
||||||
|
|
||||||
### `theo::memcpy_t` - copy memory lambda
|
|
||||||
|
|
||||||
This is used to write memory, it is never used to read memory. An example of this lambda using VDM could be:
|
|
||||||
|
|
||||||
```cpp
|
|
||||||
theo::memcpy_t _kmemcpy =
|
|
||||||
[&](void* dest, const void* src, std::size_t size) -> void*
|
|
||||||
{
|
|
||||||
static const auto kmemcpy =
|
|
||||||
reinterpret_cast<void*>(
|
|
||||||
utils::kmodule::get_export(
|
|
||||||
"ntoskrnl.exe", "memcpy"));
|
|
||||||
|
|
||||||
return vdm.syscall<decltype(&memcpy)>(kmemcpy, dest, src, size);
|
|
||||||
};
|
|
||||||
```
|
|
||||||
|
|
||||||
This uses VDM to syscall into memcpy exported by ntoskrnl... If you want to do something in usermode you can proxy memcpy to `WriteProcessMemory` or any other method of writing memory.
|
|
||||||
|
|
||||||
```cpp
|
|
||||||
theo::memcpy_t _memcpy =
|
|
||||||
[&](void* dest, const void* src, std::size_t size) -> void*
|
|
||||||
{
|
|
||||||
SIZE_T bytes_handled;
|
|
||||||
if (!WriteProcessMemory(phandle, dest, src, size, &bytes_handled))
|
|
||||||
{
|
|
||||||
std::printf("[!] failed to write process memory...\n");
|
|
||||||
exit(-1);
|
|
||||||
}
|
|
||||||
return dest;
|
|
||||||
};
|
|
||||||
```
|
|
||||||
|
|
||||||
### `theo::malloc_t` - allocate executable memory
|
|
||||||
|
|
||||||
This lambda is used to allocate executable memory. Any method will do as long as the memcpy lambda can write to the allocated memory. An MSREXEC example for this lambda is defined below.
|
|
||||||
|
|
||||||
```cpp
|
|
||||||
theo::malloc_t _kalloc = [&](std::size_t size) -> void*
|
|
||||||
{
|
|
||||||
void* alloc_base;
|
|
||||||
msrexec.exec
|
|
||||||
(
|
|
||||||
[&](void* krnl_base, get_system_routine_t get_kroutine) -> void
|
|
||||||
{
|
|
||||||
using ex_alloc_pool_t =
|
|
||||||
void* (*)(std::uint32_t, std::size_t);
|
|
||||||
|
|
||||||
const auto ex_alloc_pool =
|
|
||||||
reinterpret_cast<ex_alloc_pool_t>(
|
|
||||||
get_kroutine(krnl_base, "ExAllocatePool"));
|
|
||||||
|
|
||||||
alloc_base = ex_alloc_pool(NULL, size);
|
|
||||||
}
|
|
||||||
);
|
|
||||||
return alloc_base;
|
|
||||||
};
|
|
||||||
```
|
|
||||||
|
|
||||||
This lambda uses MSREXEC to allocate kernel memory via ExAllocatePool. However this is completely open ended on how you want to do it, you can allocate your memory into discarded
|
|
||||||
sections, you can allocate your memory in another address space, etc... Its extremely modular.
|
|
||||||
|
|
||||||
|
|
||||||
Another, yet simple, usermode example for this lambda is defined below.
|
|
||||||
|
|
||||||
```cpp
|
|
||||||
theo::malloc_t _alloc = [&](std::size_t size) -> void*
|
|
||||||
{
|
|
||||||
return VirtualAllocEx
|
|
||||||
(
|
|
||||||
phandle,
|
|
||||||
nullptr,
|
|
||||||
size,
|
|
||||||
MEM_COMMIT | MEM_RESERVE,
|
|
||||||
PAGE_EXECUTE_READWRITE
|
|
||||||
);
|
|
||||||
};
|
|
||||||
```
|
|
||||||
|
|
||||||
### `theo::resolve_symbol_t` - resolve external symbol
|
|
||||||
|
|
||||||
This lambda will try and resolve external symbols. Symbols which are not defined inside of any object files. For example `PiddbCacheTable`, an unexported ntoskrnl symbol, which normally people sig scan for, can now be jit linked. This is possible by parsing a MAP file, however you can recode this to support PDB's, etc. Again its completely opened ended on how you want to resolve symbols.
|
|
||||||
|
|
||||||
```cpp
|
|
||||||
theo::resolve_symbol_t resolve_symbol =
|
|
||||||
[&, &extern_symbols = extern_symbols](const char* symbol_name) -> std::uintptr_t
|
|
||||||
{
|
|
||||||
std::uintptr_t result = 0u;
|
|
||||||
for (auto& [drv_name, drv_symbols] : extern_symbols)
|
|
||||||
{
|
|
||||||
// each kernel module... find a driver with a matching map file name...
|
|
||||||
// I.E ntoskrnl.exe.map == ntoskrnl.exe...
|
|
||||||
utils::kmodule::each_module
|
|
||||||
(
|
|
||||||
[&, &drv_name = drv_name, &drv_symbols = drv_symbols]
|
|
||||||
(PRTL_PROCESS_MODULE_INFORMATION drv_info, const char* drv_path) -> bool
|
|
||||||
{
|
|
||||||
const auto _drv_name =
|
|
||||||
reinterpret_cast<const char*>(
|
|
||||||
drv_info->OffsetToFileName + drv_info->FullPathName);
|
|
||||||
|
|
||||||
// if this is the driver, load it, loop over its sections
|
|
||||||
// calc the absolute virtual address of the symbol...
|
|
||||||
if (!strcmp(_drv_name, drv_name.c_str()))
|
|
||||||
{
|
|
||||||
const auto drv_load_addr =
|
|
||||||
reinterpret_cast<std::uintptr_t>(
|
|
||||||
LoadLibraryExA(drv_path, NULL, DONT_RESOLVE_DLL_REFERENCES));
|
|
||||||
|
|
||||||
std::uint32_t section_count = 1u;
|
|
||||||
utils::pe::each_section
|
|
||||||
(
|
|
||||||
[&, &drv_symbols = drv_symbols]
|
|
||||||
(PIMAGE_SECTION_HEADER section_header, std::uintptr_t img_base) -> bool
|
|
||||||
{
|
|
||||||
if (section_count == drv_symbols[symbol_name].first)
|
|
||||||
{
|
|
||||||
result = reinterpret_cast<std::uintptr_t>(drv_info->ImageBase) +
|
|
||||||
section_header->VirtualAddress + drv_symbols[symbol_name].second;
|
|
||||||
|
|
||||||
// we found the symbol...
|
|
||||||
return false;
|
|
||||||
}
|
|
||||||
|
|
||||||
++section_count;
|
|
||||||
// keep going over sections...
|
|
||||||
return true;
|
|
||||||
}, drv_load_addr
|
|
||||||
);
|
|
||||||
}
|
|
||||||
|
|
||||||
// keep looping over modules until we resolve the symbol...
|
|
||||||
return !result;
|
|
||||||
}
|
|
||||||
);
|
|
||||||
}
|
|
||||||
|
|
||||||
// if the symbol was not resolved in any of the map files then try
|
|
||||||
// to see if its an export from any other drivers...
|
|
||||||
if (!result)
|
|
||||||
{
|
|
||||||
utils::kmodule::each_module
|
|
||||||
(
|
|
||||||
[&](PRTL_PROCESS_MODULE_INFORMATION drv_info, const char* drv_path) -> bool
|
|
||||||
{
|
|
||||||
const auto drv_name =
|
|
||||||
reinterpret_cast<const char*>(
|
|
||||||
drv_info->OffsetToFileName + drv_info->FullPathName);
|
|
||||||
|
|
||||||
// false if we found the symbol...
|
|
||||||
return (!(result = utils::kmodule::get_export(drv_name, symbol_name)));
|
|
||||||
}
|
|
||||||
);
|
|
||||||
}
|
|
||||||
|
|
||||||
return result;
|
|
||||||
};
|
|
||||||
```
|
|
||||||
|
|
||||||
Another example of this lambda can be viewed in the usermode examples. This routine simply loops over every single module mapped into the specific process you want to map/link with.
|
|
||||||
|
|
||||||
```cpp
|
|
||||||
theo::resolve_symbol_t _resolver =
|
|
||||||
[&, &extern_symbols = extern_symbols](const char* symbol_name) -> std::uintptr_t
|
|
||||||
{
|
|
||||||
auto loaded_modules = std::make_unique<HMODULE[]>(64);
|
|
||||||
std::uintptr_t result = 0u, loaded_module_sz = 0u;
|
|
||||||
|
|
||||||
if (!EnumProcessModules(phandle,
|
|
||||||
loaded_modules.get(), 512, (PDWORD)&loaded_module_sz))
|
|
||||||
return {};
|
|
||||||
|
|
||||||
for (auto i = 0u; i < loaded_module_sz / 8u; i++)
|
|
||||||
{
|
|
||||||
wchar_t file_name[MAX_PATH] = L"";
|
|
||||||
if (!GetModuleFileNameExW(phandle,
|
|
||||||
loaded_modules.get()[i], file_name, _countof(file_name)))
|
|
||||||
continue;
|
|
||||||
|
|
||||||
if ((result = reinterpret_cast<std::uintptr_t>(
|
|
||||||
GetProcAddress(LoadLibrary(file_name), symbol_name))))
|
|
||||||
break;
|
|
||||||
}
|
|
||||||
|
|
||||||
return result;
|
|
||||||
};
|
|
||||||
```
|
|
||||||
|
|
||||||
### Creating Instance
|
|
||||||
|
|
||||||
Once all three lambdas are defined, you can then create a `theo::hmm_ctx` (highly modular mapper context). This class is like the one from HMDM however it requires an extra lambda to resolve external symbols.
|
|
||||||
|
|
||||||
```cpp
|
|
||||||
theo::hmm_ctx drv_mapper({ _alloc, _memcpy, _resolver });
|
|
||||||
|
|
||||||
const auto drv_entry =
|
|
||||||
reinterpret_cast<LPTHREAD_START_ROUTINE>(
|
|
||||||
drv_mapper.map_objs(image_objs));
|
|
||||||
```
|
|
||||||
|
|
||||||
### Calling Entry
|
|
||||||
|
|
||||||
#### MSREXEC - Call Entry Example
|
|
||||||
|
|
||||||
The entry point of the mapped code is not invoked by `hmm_ctx`, but rather its left up to you to call. An example of calling the entry point can be seen below.
|
|
||||||
|
|
||||||
```cpp
|
|
||||||
int result;
|
|
||||||
msrexec.exec([&result, drv_entry = drv_entry]
|
|
||||||
(void* krnl_base, get_system_routine_t get_kroutine) -> void
|
|
||||||
{
|
|
||||||
using drv_entry_t = int(*)();
|
|
||||||
result = reinterpret_cast<drv_entry_t>(drv_entry)();
|
|
||||||
});
|
|
||||||
```
|
|
||||||
|
|
||||||
#### VDM - Call Entry Example
|
|
||||||
|
|
||||||
Another example, this one using VDM, can be seen below.
|
|
||||||
|
|
||||||
```cpp
|
|
||||||
const auto entry_result =
|
|
||||||
vdm.syscall<NTSTATUS(*)()>(
|
|
||||||
reinterpret_cast<void*>(drv_entry));
|
|
||||||
```
|
|
||||||
|
|
||||||
#### WinAPI - Call Entry Example
|
|
||||||
|
|
||||||
Another example, this one using WinAPI's, can be seen below.
|
|
||||||
|
|
||||||
```cpp
|
|
||||||
std::uint32_t tid = 0u;
|
|
||||||
CreateRemoteThread
|
|
||||||
(
|
|
||||||
phandle, NULL,
|
|
||||||
NULL, drv_entry,
|
|
||||||
NULL, NULL,
|
|
||||||
(LPDWORD)&tid
|
|
||||||
);
|

## RIP Relative Addressing
|
|
||||||
|
|
||||||
In order to allow for a routine to be scattered throughout a 64bit address space, RIP relative addressing must not be used. In order to facilitate this, a very special version
|
|
||||||
of clang-cl is used which can use `mcmodel=large`. This will generate instructions which do not use RIP relative addressing when referencing symbols outside of the routine in which the
|
|
||||||
instruction itself resides. The only exception to this is JCC instructions, (besides call) also known as branching instructions. Take this c++ code for an example:
|
|
||||||
|
|
||||||
```cpp
|
|
||||||
ObfuscateRoutine
|
|
||||||
extern "C" int ModuleEntry()
|
|
||||||
{
|
|
||||||
MessageBoxA(0, "Demo", "Hello From Obfuscated Routine!", 0);
|
|
||||||
UsermodeMutateDemo();
|
|
||||||
UsermodeNoObfuscation();
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
This c++ function, compiled by clang-cl with `mcmodel=large`, will generate a routine with the following instructions:
|
|
||||||
|
|
||||||
```
|
|
||||||
0x00: ; void UsermodeNoObfuscation(void)
|
|
||||||
0x00: public ?UsermodeNoObfuscation@@YAXXZ
|
|
||||||
0x00: ?UsermodeNoObfuscation@@YAXXZ proc near ; CODE XREF: ModuleEntry+42↓p
|
|
||||||
0x00: var_4 = dword ptr -4
|
|
||||||
0x00: 48 83 EC 28 sub rsp, 28h
|
|
||||||
0x04: C7 44 24 24 00 00 00 00 mov [rsp+28h+var_4], 0
|
|
||||||
0x0C: loc_C:
|
|
||||||
0x0C: 83 7C 24 24 05 cmp [rsp+28h+var_4], 5
|
|
||||||
0x11: 0F 83 38 00 00 00 jnb loc_4F
|
|
||||||
0x17: 31 C0 xor eax, eax
|
|
||||||
0x19: 48 BA 28 01 00 00 00 00 00 00 mov rdx, offset ??_C@_04DKDMNOEB@Demo?$AA@ ; "Demo"
|
|
||||||
0x23: 49 B8 00 01 00 00 00 00 00 00 mov r8, offset ??_C@_0CD@JEJKPGNA@Hello?5... ; "Hello From Non-Obfuscated Routine!"
|
|
||||||
0x2D: 48 B8 A0 01 00 00 00 00 00 00 mov rax, offset MessageBoxA
|
|
||||||
0x37: 45 31 C9 xor r9d, r9d ; uType
|
|
||||||
0x3A: 44 89 C9 mov ecx, r9d ; hWnd
|
|
||||||
0x3D: FF D0 call rax ; MessageBoxA
|
|
||||||
0x3F: 8B 44 24 24 mov eax, [rsp+28h+var_4]
|
|
||||||
0x43: 83 C0 01 add eax, 1
|
|
||||||
0x46: 89 44 24 24 mov [rsp+28h+var_4], eax
|
|
||||||
0x4A: E9 BD FF FF FF jmp loc_C
|
|
||||||
0x4F: loc_4F:
|
|
||||||
0x4F: 48 83 C4 28 add rsp, 28h
|
|
||||||
0x53: C3 retn
|
|
||||||
0x53: ?UsermodeNoObfuscation@@YAXXZ endp
|
|
||||||
```
|
|
||||||
|
|
||||||
As you can see from the code above, (sorry for the terrible syntax highlighting), references to strings and calls to functions are done by first loading the address of the symbol into a register and then interfacing with the symbol.
|
|
||||||
|
|
||||||
```
|
|
||||||
0x2D: 48 B8 A0 01 00 00 00 00 00 00 mov rax, offset MessageBoxA
|
|
||||||
; ...
|
|
||||||
0x3D: FF D0 call rax ; MessageBoxA
|
|
||||||
```
|
|
||||||
|
|
||||||
Each of these instructions can be anywhere in virtual memory and it would not effect code execution one bit. However this is not the case with routines which have conditional branches. Take the following c++ code for example.
|
|
||||||
|
|
||||||
## JCC - RIP Relative
|
|
||||||
|
|
||||||
```cpp
|
|
||||||
ObfuscateRoutine
|
|
||||||
void LoopDemo()
|
|
||||||
{
|
|
||||||
for (auto idx = 0u; idx < 10; ++idx)
|
|
||||||
DbgPrint("> Loop Demo: %d\n", idx);
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
This c++ function, compiled by clang-cl with `mcmodel=large`, will generate a routine with the following instructions:
|
|
||||||
|
|
||||||
```
|
|
||||||
0x58 ; void LoopDemo(void)
|
|
||||||
0x58 public ?LoopDemo@@YAXXZ
|
|
||||||
0x58 ?LoopDemo@@YAXXZ proc near
|
|
||||||
0x58 var_4 = dword ptr -4
|
|
||||||
0x58
|
|
||||||
0x58 48 83 EC 28 sub rsp, 28h
|
|
||||||
0x5C C7 44 24 24 00 00 00 00 mov [rsp+28h+var_4], 0
|
|
||||||
0x64 loc_64:
|
|
||||||
0x64 83 7C 24 24 0A cmp [rsp+28h+var_4], 0Ah
|
|
||||||
0x69 0F 83 2A 00 00 00 jnb loc_99
|
|
||||||
0x6F 8B 54 24 24 mov edx, [rsp+28h+var_4]
|
|
||||||
0x73 48 B9 60 01 00 00 00 00 00 00 mov rcx, offset ??_C@_0BB@HGKDPLMC@?$.... ; "> Loop Demo: %d\n"
|
|
||||||
0x7D 48 B8 38 02 00 00 00 00 00 00 mov rax, offset DbgPrint
|
|
||||||
0x87 FF D0 call rax ; DbgPrint
|
|
||||||
0x89 8B 44 24 24 mov eax, [rsp+28h+var_4]
|
|
||||||
0x8D 83 C0 01 add eax, 1
|
|
||||||
0x90 89 44 24 24 mov [rsp+28h+var_4], eax
|
|
||||||
0x94 E9 CB FF FF FF jmp loc_64
|
|
||||||
0x99 loc_99:
|
|
||||||
0x99 48 83 C4 28 add rsp, 28h
|
|
||||||
0x9D C3 retn
|
|
||||||
0x9D ?LoopDemo@@YAXXZ endp
|
|
||||||
```
|
|
||||||
|
|
||||||
Uh oh, `jnb loc_99`?, thats RIP relative! In order to handle branching operations, a "jump table" is generated by `obfuscation::obfuscate` explicit default constructor. Instead of branching to the RIP relative code, it will instead branch to an inline jump (`JMP [RIP+0x0]`). As demonstrated below, the branching operation is altered to branch to an asbolute jump.
|
|
||||||
|
|
||||||
```
|
|
||||||
ffff998b`c5369e60 0f830e000000 jnb ffff998b`c5369e74
|
|
||||||
ffff998b`c5369e66 ff2500000000 jmp qword ptr [ffff998b`c5369e6c]
|
|
||||||
...
|
|
||||||
ffff998b`c5369e74 ff2500000000 jmp qword ptr [ffff998b`c5369e7a]
|
|
||||||
```
|
|
||||||
|
|
||||||
The linker is able to get the address of the branching code by taking the rip relative virtual address of the branching operation, which is a signed number, and adding it to the current byte offset into the current routine, plus the size of the branching instruction. For example `LoopDemo@17` + size of the branching instruction, which is six bytes, then adding the signed relative virtual address (0x2A). The result of this simple calculation gives us `LoopDemo@65`, which is correct, the branch goes to `add rsp, 28h` in the above example.
|
|
||||||
|
|
||||||
## Obfuscation
|
|
||||||
|
|
||||||
The usage of the word obfuscation in this project is use to define any changes made to code, this includes code flow. `obfuscation::obfuscate`, a base class, which is inherited and expanded upon by `obfuscation::mutation`, obfuscates code flow by inserting `JMP [RIP+0x0]` instructions after every single instruction. This allows for a routine to be broken up into unique allocations of memory and thus provides more canvas room for creative ideas.
|
|
||||||
|
|
||||||
### Obfuscate - Base Class
|
|
||||||
|
|
||||||
The base class, as described in the above section, contains a handful of util routines and a single explicit constructor which is the corner stone of the class. The constructor fixes JCC relative virtual addresses so that if the condition is met, instead of jumping instruction pointer relativitly, it will jump to an addition jmp (`JMP [RIP+0x0]`).
|
|
||||||
|
|
||||||
|
|
||||||
LEA's, nor CALL's are rip relative, even for symbols defined inside of the routine in which the instruction is compiled into. In other words JCC instructions are the only instruction pointer relative instructions that are generated.
|
|
||||||
|
|
||||||
|
|
||||||
```
|
|
||||||
instruction
|
|
||||||
jmp next instruction
|
|
||||||
|
|
||||||
|
|
||||||
instruction
|
|
||||||
jmp next instruction
|
|
||||||
|
|
||||||
|
|
||||||
instruction
|
|
||||||
jmp next instruction
|
|
||||||
```
|
|
||||||
|
|
||||||
### Mutation - Inherts Obfuscation
|
|
||||||
|
|
||||||
This class inherits from `obfuscate` and adds additional code, or "mutation". This class is a small example of how to use inheritance with `obfuscate` base class. It generates a stack push/pop palindrome. The state of the stack is restored before the routines actual instruction is executed. The assembly will now look like this in memory:
|
|
||||||
|
|
||||||
```
|
|
||||||
push gp
|
|
||||||
push gp
|
|
||||||
push gp
|
|
||||||
...
|
|
||||||
pop gp
|
|
||||||
pop gp
|
|
||||||
pop gp
|
|
||||||
exec routine instruction
|
|
||||||
jmp next instruction
|
|
||||||
|
|
||||||
push gp
|
|
||||||
push gp
|
|
||||||
push gp
|
|
||||||

|
|
||||||

|
|
||||||
...
|
|
||||||

|
|
||||||
pop gp
|
|
||||||
pop gp
|
|
||||||
pop gp
|
|
||||||
pop gp
|
|
||||||
exec routine instruction
|
|
||||||
jmp next instruction
|
|
||||||
|
|
||||||
push gp
|
|
||||||
push gp
|
|
||||||
push gp
|
|
||||||
...
|
|
||||||
pop gp
|
|
||||||
pop gp
|
|
||||||
pop gp
|
|
||||||
exec routine instruction
|
|
||||||
jmp next instruction
|
|
||||||
```
|
|
||||||
|
|
||||||
Again this is just a demo/POC on how you can inherit `obfuscate`. This also shows an example of how to use `asmjit`.
|
|
||||||
|
|
||||||
# Examples

|
||||||
|
|
||||||
### Kernel Example
|
|
||||||
|
|
||||||
<img src="https://githacks.org/_xeroxz/theodosius/-/raw/d286946c4727c91e0ca8d6059335382f00db4b91/imgs/kernel-example-2.png"/>
|
|
||||||
|
|
||||||
This example uses MSREXEC and Theodosius to map unsigned code into the kernel. This example is inside of the "Examples" folder. I would also like to note that in this demo external unexported ntoskrnl symbols are resolved by using a MAP file. This map file looks like this:
|
|
||||||
|
|
||||||
```
|
|
||||||
00000001:0000000000000F10 KiOpTwoByteTable
|
|
||||||
00000001:0000000000001168 SeSubsystemName
|
|
||||||
00000001:0000000000001180 PlugPlayHandlerTable
|
|
||||||
00000001:00000000000013E0 PiDmAggregatedBooleanDefs
|
|
||||||
00000001:0000000000001490 PiDmCachedDeviceKeys
|
|
||||||
00000001:0000000000001580 PiDmCachedDeviceInterfaceKeys
|
|
||||||
00000001:00000000000015F0 AllowedCachedObjectNames
|
|
||||||
00000001:0000000000001640 EmptyUnicodeString
|
|
||||||
```
|
|
||||||
|
|
||||||
Mind the space at the beginning of each line. If you want to generate a file like this, put ntoskrnl.exe into IDA Pro and then click File ---> Produce File ---> Create MAP File, dont select "Segment Information", but do select "Demangled Names". After the MAP file is generate, please delete all of the garbage at the beginning of the file. I.E delete all spaces and "Address, Public By Value" stuff.
|
|
||||||
|
|
||||||
```
|
|
||||||
|
|
||||||
|
|
||||||
Address Publics by Value
|
|
||||||
|
|
||||||
00000001:0000000000000000 VrpRegistryString
|
|
||||||
....
|
|
||||||
```
|
|
||||||
|
|
||||||
Once you have generated a map file for ntoskrnl.exe, or any other binary you want to link with, you can then use it to resolve external symbols. In the `DemoDrv` project, I reference two external symbols. One being `PiddbCacheTable`, and the other being a win32kfull.sys export.
|
|
||||||
|
|
||||||
```cpp
|
|
||||||
// this is a demo of resolving non-exported symbols...
|
|
||||||
// win32kfull.sys export example...
|
|
||||||
extern "C" void NtUserRegisterShellPTPListener();
|
|
||||||
extern "C" void* PiDDBCacheTable;
|
|
||||||
|
|
||||||
```
|
|
||||||
|
|
||||||
These two symbols are simply printed out via DbgPrint.
|
|
||||||
|
|
||||||
```cpp
|
|
||||||
MutateRoutine extern "C" void DrvEntry()
|
|
||||||
{
|
|
||||||
DbgPrint("> Hello World!\n");
|
|
||||||
|
|
||||||
// non-exported symbols being resolved by jit linker...
|
|
||||||
DbgPrint("> PiDDBCacheTable = 0x%p\n", &PiDDBCacheTable);
|
|
||||||
DbgPrint("> win32kfull!NtUserRegisterShellPTPListener = 0x%p\n", &NtUserRegisterShellPTPListener);
|
|
||||||
|
|
||||||
// example of referencing itself...
|
|
||||||
DbgPrint("> DrvEntry = 0x%p\n", &DrvEntry);
|
|
||||||
|
|
||||||
// example of calling other obfuscated/non obfuscated routines...
|
|
||||||
PrintCR3();
|
|
||||||
LoopDemo();
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
Once compiled the assembly will look like this. Note that each reference to symbols is done via a relocation to an absolute address. This means strings can (and will) be mapped into their own allocation of memory.
|
|
||||||
|
|
||||||
```
|

||||||

Theo calculates the size of each symbol by subtracting the address of the next symbol (in the same section), from the address of the symbol itself. If the symbol is the last one in a section, the distance between the start of the symbol and the end of the section is used. Now lets take a look at what happens when we link/map this routine. Theo starts by allocating space for all non-obfuscated symbols.
|
|
||||||

|
||||||

```
|
|
||||||
|
|
||||||
As you can see, each string gets its own pool, each global variable does too, and every non-obfuscated routine is mapped into its own pool. The memory however, has not been copied yet since there are relocations that need to happen before they are copied into memory (in PrintCr3).
|
|
||||||
|
|
||||||
The next thing Theo does is allocate space for obfuscated routines. In the `DemoDrv`, there is a demo for each type of obfuscation (just mutation and control flow obfuscation for now).

As you can see, Theo uses Zydis to go over all routines marked for obfuscation and generates new symbols for each instruction inside of the routine. The symbol goes by `[RoutineName]@[Instruction Offset]`. Note that JCC's are indeed rip relative, these need to be fixed.
|
|
||||||
|
|
||||||
```
|
|
||||||
> fixing JCC rva...
|
|
||||||
> new rva = 0xe
|
|
||||||
> old rva = 0x2a
|
|
||||||
> ?LoopDemo@@YAXXZ@17 allocated = 0xFFFF998BC5369E60, size = 34
|
|
||||||
```
|
|
||||||
|
|
||||||
Note that in DemoDrv there is a function called "LoopDemo" which is obfuscated. Instead of the JCC instruction branching to the conditional code, it instead branches to an inline jmp. If it doesnt branch, then it simply jumps to the next instruction like normal.
|
|
||||||
|
|
||||||
```
|
|
||||||
ffff998b`c5369e60 0f830e000000 jae ffff998b`c5369e74
|
|
||||||
ffff998b`c5369e66 ff2500000000 jmp qword ptr [ffff998b`c5369e6c]
|
|
||||||
ffff998b`c5369e74 ff2500000000 jmp qword ptr [ffff998b`c5369e7a]
|
|
||||||
```
|
|
||||||
|
|
||||||
As you can see above, this is what Theo generates for JCC's. Also note that this clang compiler does not generate RIP relative LEA's or CALL's. The only RIP relative stuff Theo deals with are JCC's.
|
|
||||||
|
|
||||||
#### Memory View Of Obfuscation

|
||||||
|
|
||||||
The instructions for `LoopDemo` now look like this in memory:

This example uses WinAPI's to allocate virtual memory in another process and also to copy virtual memory. Only exported routines from loaded DLL's in the target process can be resolved.

// dear imgui: Renderer Backend for DirectX11
|
|
||||||
// This needs to be used along with a Platform Backend (e.g. Win32)
|
|
||||||
|
|
||||||
// Implemented features:
|
|
||||||
// [X] Renderer: User texture binding. Use 'ID3D11ShaderResourceView*' as ImTextureID. Read the FAQ about ImTextureID!
|
|
||||||
// [X] Renderer: Support for large meshes (64k+ vertices) with 16-bit indices.
|
|
||||||
|
|
||||||
// You can copy and use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
|
|
||||||
// If you are new to Dear ImGui, read documentation from the docs/ folder + read the top of imgui.cpp.
|
|
||||||
// Read online: https://github.com/ocornut/imgui/tree/master/docs
|
|
||||||
|
|
||||||
// CHANGELOG
|
|
||||||
// (minor and older changes stripped away, please see git history for details)
|
|
||||||
// 2021-02-18: DirectX11: Change blending equation to preserve alpha in output buffer.
|
|
||||||
// 2019-08-01: DirectX11: Fixed code querying the Geometry Shader state (would generally error with Debug layer enabled).
|
|
||||||
// 2019-07-21: DirectX11: Backup, clear and restore Geometry Shader is any is bound when calling ImGui_ImplDX10_RenderDrawData. Clearing Hull/Domain/Compute shaders without backup/restore.
|
|
||||||
// 2019-05-29: DirectX11: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
|
|
||||||
// 2019-04-30: DirectX11: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
|
|
||||||
// 2018-12-03: Misc: Added #pragma comment statement to automatically link with d3dcompiler.lib when using D3DCompile().
|
|
||||||
// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
|
|
||||||
// 2018-08-01: DirectX11: Querying for IDXGIFactory instead of IDXGIFactory1 to increase compatibility.
|
|
||||||
// 2018-07-13: DirectX11: Fixed unreleased resources in Init and Shutdown functions.
|
|
||||||
// 2018-06-08: Misc: Extracted imgui_impl_dx11.cpp/.h away from the old combined DX11+Win32 example.
|
|
||||||
// 2018-06-08: DirectX11: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
|
|
||||||
// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplDX11_RenderDrawData() in the .h file so you can call it yourself.
|
|
||||||
// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
|
|
||||||
// 2016-05-07: DirectX11: Disabling depth-write.

// This is a slightly modified version of stb_rect_pack.h 1.00.
|
|
||||||
// Those changes would need to be pushed into nothings/stb:

// stb_rect_pack.h - v1.00 - public domain - rectangle packing
|
|
||||||
// Sean Barrett 2014
|
|
||||||
//
|
|
||||||
// Useful for e.g. packing rectangular textures into an atlas.
|
|
||||||
// Does not do rotation.
|
|
||||||
//
|
|
||||||
// Not necessarily the awesomest packing method, but better than
|
|
||||||
// the totally naive one in stb_truetype (which is primarily what
|
|
||||||
// this is meant to replace).
|
|
||||||
//
|
|
||||||
// Has only had a few tests run, may have issues.
|
|
||||||
//
|
|
||||||
// More docs to come.
|
|
||||||
//
|
|
||||||
// No memory allocations; uses qsort() and assert() from stdlib.
|
|
||||||
// Can override those by defining STBRP_SORT and STBRP_ASSERT.
|
|
||||||
//
|
|
||||||
// This library currently uses the Skyline Bottom-Left algorithm.
|
|
||||||
//
|
|
||||||
// Please note: better rectangle packers are welcome! Please
|
|
||||||
// implement them to the same API, but with a different init
|

|
|

// Helper tool to turn a file into a C array, if you want to embed font data in your source code.
|
|
||||||
|
|
||||||
// The data is first compressed with stb_compress() to reduce source code size,
|
|
||||||
// then encoded in Base85 to fit in a string so we can fit roughly 4 bytes of compressed data into 5 bytes of source code (suggested by @mmalex)
|
|
||||||
// (If we used 32-bit constants it would require take 11 bytes of source code to encode 4 bytes, and be endianness dependent)
|
|
||||||
// Note that even with compression, the output array is likely to be bigger than the binary file..
|
|
||||||
// Load compressed TTF fonts with ImGui::GetIO().Fonts->AddFontFromMemoryCompressedTTF()
|
|
||||||
|
|
||||||
// Build with, e.g:
|
|
||||||
// # cl.exe binary_to_compressed_c.cpp
|
|
||||||
// # g++ binary_to_compressed_c.cpp
|
|
||||||
// # clang++ binary_to_compressed_c.cpp
|
|
||||||
// You can also find a precompiled Windows binary in the binary/demo package available from https://github.com/ocornut/imgui
|
|
||||||
|
|
||||||
// Usage:
|
|
||||||
// binary_to_compressed_c.exe [-base85] [-nocompress] <inputfile> <symbolname>
|

// Usage example:
|

# imgui_freetype
|
|
||||||
|
|
||||||
Build font atlases using FreeType instead of stb_truetype (which is the default font rasterizer).
|
|
||||||
<br>by @vuhdo, @mikesart, @ocornut.
|
|
||||||
|
|
||||||
### Usage
|
|
||||||
|
|
||||||
1. Get latest FreeType binaries or build yourself (under Windows you may use vcpkg with `vcpkg install freetype`, `vcpkg integrate install`).
|
|
||||||
2. Add imgui_freetype.h/cpp alongside your project files.
|
|
||||||
3. Add `#define IMGUI_ENABLE_FREETYPE` in your [imconfig.h](https://github.com/ocornut/imgui/blob/master/imconfig.h) file
|
|
||||||
|
|
||||||
### About Gamma Correct Blending
|
|
||||||
|
|
||||||
FreeType assumes blending in linear space rather than gamma space.
|
|
||||||
See FreeType note for [FT_Render_Glyph](https://www.freetype.org/freetype2/docs/reference/ft2-base_interface.html#FT_Render_Glyph).
|
|
||||||
For correct results you need to be using sRGB and convert to linear space in the pixel shader output.
|
|
||||||
The default Dear ImGui styles will be impacted by this change (alpha values will need tweaking).
|
|
||||||
|
|
||||||
### Testbed for toying with settings (for developers)
|
|
||||||
|
|
||||||
See https://gist.github.com/ocornut/b3a9ecf13502fd818799a452969649ad
|
|
||||||
|
|
||||||
### Known issues
|
|
||||||
|
|
||||||
- Oversampling settins are ignored but also not so much necessary with the higher quality rendering.
|
|
||||||
|
|
||||||
### Comparaison
|
|
||||||
|
|
||||||
Small, thin anti-aliased fonts are typically benefiting a lots from Freetype's hinting:

// CHANGELOG
|
|
||||||
// (minor and older changes stripped away, please see git history for details)
|
|
||||||
// 2021/03/05: added ImGuiFreeTypeBuilderFlags_Bitmap to load bitmap glyphs.
|
|
||||||
// 2021/03/02: set 'atlas->TexPixelsUseColors = true' to help some backends with deciding of a prefered texture format.
|
|
||||||
// 2021/01/28: added support for color-layered glyphs via ImGuiFreeTypeBuilderFlags_LoadColor (require Freetype 2.10+).
|
|
||||||
// 2021/01/26: simplified integration by using '#define IMGUI_ENABLE_FREETYPE'.
|
|
||||||
// renamed ImGuiFreeType::XXX flags to ImGuiFreeTypeBuilderFlags_XXX for consistency with other API. removed ImGuiFreeType::BuildFontAtlas().
|
|
||||||
// 2020/06/04: fix for rare case where FT_Get_Char_Index() succeed but FT_Load_Glyph() fails.
|
|
||||||
// 2019/02/09: added RasterizerFlags::Monochrome flag to disable font anti-aliasing (combine with ::MonoHinting for best results!)
|
|
||||||
// 2019/01/15: added support for imgui allocators + added FreeType only override function SetAllocatorFunctions().
|
|
||||||
// 2019/01/10: re-factored to match big update in STB builder. fixed texture height waste. fixed redundant glyphs when merging. support for glyph padding.
|
|
||||||
// 2018/06/08: added support for ImFontConfig::GlyphMinAdvanceX, GlyphMaxAdvanceX.
|
|
||||||
// 2018/02/04: moved to main imgui repository (away from http://www.github.com/ocornut/imgui_club)
|
|
||||||
// 2018/01/22: fix for addition of ImFontAtlas::TexUvscale member.
|
|
||||||
// 2017/10/22: minor inconsequential change to match change in master (removed an unnecessary statement).
|
|
||||||
// 2017/09/26: fixes for imgui internal changes.
|
|
||||||
// 2017/08/26: cleanup, optimizations, support for ImFontConfig::RasterizerFlags, ImFontConfig::RasterizerMultiply.
|
|
||||||
// 2017/08/16: imported from https://github.com/Vuhdo/imgui_freetype into http://www.github.com/ocornut/imgui_club, updated for latest changes in ImFontAtlas, minor tweaks.
