您好～在发出这份issues之前，我已经仔细拜读了您在看雪论坛的文章，并且在服务器环境尝试复现，但是我遇到了一些问题，请允许我向您详细说明，希望能获得您的帮助，感谢～

复现环境

• 服务器:Ubuntu 20.04 x64
• 目标NDK:23.1.7779620
• 添加的PASS:Pluto-Obfuscator

操作方式

其实就是按照您在看雪论坛的介绍来走的 已经重复操作3次 应该没有漏掉什么步骤 下面我简单描述一下操作步骤

• 下载repo

  curl https://storage.googleapis.com/git-repo-downloads/repo > /usr/bin/repo
  chmod a+x /usr/bin/repo
  

• repo下载对应版本的源码

  mkdir ndk-llvm && cd ndk-llvm
  repo init -u https://android.googlesource.com/platform/manifest -b llvm-toolchain
  cp $TOOLCHAIN_DIR/manifest_7714059.xml .repo/manifests
  repo init -m manifest_7714059.xml
  repo sync -c
  

• 安装/修复必要环境

  sudo apt-get install cmake bison
  find /usr/lib -name libffi.so*
  ln -s /usr/lib/x86_64-linux-gnu/libffi.so.7 /usr/lib/x86_64-linux-gnu/libffi.so.6
  

• 开始编译流程

  python toolchain/llvm_android/build.py --no-build linux
  

• 添加PASS 这一步大佬在看雪论坛的文章中 漏掉了一些小步骤 不过无伤大雅 下面我简单对步骤进行概括

• 添加/include/llvm/Transforms/Obfuscation <-- 此步大佬遗漏
• 添加/lib/Transforms/Obfuscation
• 修改/lib/Transforms/IPO/PassManagerBuilder.cpp三处代码
• 在/lib/Transforms/IPO/CMakeLists.txt中添加Obfuscation
• 在/lib/Transforms/CMakeLists.txt中添加Obfuscation <--此步大佬遗漏

• 重新编译

  python toolchain/llvm_android/build.py --no-build linux
  

得益于大佬您的文章介绍，我的编译流程比较顺利，中间没有因为erro而产生中断

出现的问题

就好像 #5 遇到的问题一样 我使用的是ndk-build脚本， #5 貌似使用的是cmake，不过情况都是一样的 我们自己编译的 ndk-r23，在移植后出现一些报错情况，关键内容如下:

....../build/core/setup-toolchain.mk:111: pipe: No error
....../build/core/prebuilt-library.mk:45: *** Android NDK: Aborting    .  Stop.
....../sources/cxx-stl/llvm-libc++abi/Android.mk:unwind: LOCAL_SRC_FILES points to a missing file 
......Android NDK: Check that /lib/linux/arm/libunwind.a exists  or that its path is correct 

在参考了 #5 以后，我也查看了一下编译产物的格式

• 这是我们自己编译的产物

  [email protected]:~/ndk-llvm-r416183c1/out/install/windows-x86/clang-dev/bin# file clang*
  clang-check.exe:  PE32+ executable (console) x86-64, for MS Windows
  clang-cl.exe:     symbolic link to clang.exe
  clang++.exe:      symbolic link to clang.exe
  clang.exe:        PE32+ executable (console) x86-64, for MS Windows
  clang-format.exe: PE32+ executable (console) x86-64, for MS Windows
  clang-tidy.exe:   PE32+ executable (console) x86-64, for MS Windows
  

• 这是从谷歌官网下载的ndk

  ❯ file clang*
  clang++.exe:      PE32+ executable (console) x86-64, for MS Windows
  clang-check.exe:  PE32+ executable (console) x86-64, for MS Windows
  clang-cl.exe:     PE32+ executable (console) x86-64, for MS Windows
  clang-format.exe: PE32+ executable (console) x86-64, for MS Windows
  clang-tidy.exe:   PE32+ executable (console) x86-64, for MS Windows
  clang.exe:        PE32+ executable (console) x86-64, for MS Windows
  

如果可以，我也想看一看大佬编译产物的格式，确认这之间是否存在差异

自己尝试过的研究

我本人使用的是macOS，最初是想要按照大佬的思路去编译mac版本的toolchain。 不过我发现按照谷歌官方对toolchain/llvm_android步骤操作后，有且只有Windows版本和Linux版本的clang-dev。 没有android/toolchain/prebuilts/ndk-darwin/r23中的产物，遂将目光转移到Windows版本的PASS移植。 这里插一嘴，如果大佬知道macOS版本的toolchain如何编译的话，烦请指点。

1. 既然说按照大佬的文章操作，我这里出现了一点点问题，那么换一个角度。 我在macOS上按照常规方法操作，将大佬的项目clone下来以后，按照README的说法，使用cmake对大佬的项目进行构建。 即:添加PASS再编译llvm以后，将bin目录生成的工具替换到ndk中的toolchain里面去。 同时将编译后的lib64添加到ndk中toolchain的lib64里面去，同时修复头文件缺失问题以后。

   关于llvm编译后生成lib64目录

   如果我们单独在编译llvm时，为了适配ndk，应该对cmake编译添加参数 -DLLVM_LIBDIR_SUFFIX=64 ，即可让lib自动重命名为lib64，以此解决环境依赖问题，详细请参考Google的build.py脚本

   遗憾的是，在移植完成以后，`ndk-build`依然报错，由于未能及时记录报错信息，这里的erro无法进行展示，抱歉。 同时，我观察到，ndk中toolchain的clang-12约100+MB，可是我编译的貌似只有1MB大小，这是否是因为我仅只是clone了大佬的项目，直接进行编译，而没有将他们移植到整个llvm-project中导致的？

2. 会不会在编译进PASS之前，bin目录的文件格式正常？ 抱着这种想法，我重开项目，并且在没有添加PASS情况下，编译出了out产物。 很遗憾的是，我发现，对于ndk-r23b来说，即使我们没有添加PASS，他的编译产物格式依然如下:

   [email protected]:~/ndk-llvm-r416183c1/out/install/windows-x86/clang-dev/bin# file clang*
   clang-check.exe:  PE32+ executable (console) x86-64, for MS Windows
   clang-cl.exe:     symbolic link to clang.exe
   clang++.exe:      symbolic link to clang.exe
   clang.exe:        PE32+ executable (console) x86-64, for MS Windows
   clang-format.exe: PE32+ executable (console) x86-64, for MS Windows
   clang-tidy.exe:   PE32+ executable (console) x86-64, for MS Windows
   

   也就是说，我们自己编译的ndk-r23b的toolchain，就是和谷歌官方不一样的文件格式，即使没有添加进PASS

3. 我的第二个分析，似乎是在说明，我们自己编译的toolchain是错误的，无法使用，但是谷歌官方的教程:Instructions to rebuild a particular toolchain release似乎也就是这样，我们并没有遗漏掉什么。 不甘心放弃，于是，我对老版本的ndk-22.1.7171670进行编译，发现了有意思的事情。 对老版本ndk-22.1.7171670进行编译以后，我对编译产物进行file发现:

   [email protected]:~/ndk-llvm-r416183c1/out/install/windows-x86/clang-dev/bin# file clang*
   clang++.exe:      PE32+ executable (console) x86-64, for MS Windows
   clang-check.exe:  PE32+ executable (console) x86-64, for MS Windows
   clang-cl.exe:     PE32+ executable (console) x86-64, for MS Windows
   clang-format.exe: PE32+ executable (console) x86-64, for MS Windows
   clang-tidy.exe:   PE32+ executable (console) x86-64, for MS Windows
   clang.exe:        PE32+ executable (console) x86-64, for MS Windows
   

   按照这种方式，编译的老版本ndk居然是正常的！没有出现所谓的symbolic link to clang.exe！ 果断添加PASS重新编译 --> 再次file -- > 文件格式正常！ --> 移植ndk -- > 测试ndk-build 让人欣喜的事情来了，在file文件格式全部正常的情况下，使用ndk-build，编译过程没有任何问题！没有报错！ 到这里，我们至少确认了一件事，那就是，之前的报错就是因为file文件格式不正确导致的 于是，添加混淆参数，进行混淆编译 --> 未混淆编译产物5kb，混淆后编译产物23kb 貌似成功了？抱着激动的心情，打开ida，分别对比未混淆和混淆后，让我失望的事情来了，混淆前后在ida中的表现是一样的。 也就是说，除了文件体积的变化外，文件并没有得到更安全的保护。

4. 转念一想，大佬您的这款PASS是基于llvm-12编写的，也许他对老版本的ndk所采用的llvm-11是不生效的。 于是，我换用了heroims大佬的PASS，移植结束以后 file文件格式依然全部正常，编译流程没有erro <-- 这里再次证明，ndk-r23b的toolchain之所以报错，就是因为file格式问题 很遗憾的是，虽然编译确实没有报错，混淆前后文件大小确实也产生变化，但是，使用ida进行查看的时候，混淆依然没有生效。

   顺便一提，我们ndk-r23b使用的是clang12，在heroims大佬项目的issues中 我找到了libunwind.a有关报错的解决方案https://github.com/heroims/obfuscator/issues/7#issuecomment-1025939903 导致该问题的原因，大概就是谷歌build.py脚本让lib自动重命名为lib64，产生的环境依赖问题 但由于我们本身就应该是build.py构建的环境，不应该有这种报错才对

最后

至此，我已经无计可施，本以为是谷歌ndk在r23版本存在某种问题。 但是转念一想，大佬您已经在和我相同的ndk版本下，实测成功，并且上传了examples。 我认为，是我在某些步骤上的操作有所遗漏或者错误。 希望大佬能够分析一下我的流程有哪些地方存在问题，不胜感激～

Hi! I have compiled the project by following your instruction on bbs.pediy forum, everything goes smoothly but for some reason I cannot compile my project in Android Studio, following error shows whenever I try to compile.

The error states that Android NDK: Check that /lib/linux/arm/libunwind.a exists or that its path is correct but the file is clearly present under the path F:\AndroidSdk\ndk\pluto-ndk\toolchains\llvm\prebuilt\windows-x86_64\lib64\clang\12.0.8\lib\linux\arm

One more thing I have noticed that the clang++ of newly compile llvm cannot be executed, it states that 16-bit applications are not supported whereas the clang++ of original ndk is executed without any issue.

Dont know if its worth mentioning or not, but I compiled the modified llvm in ubuntu.

Any help or insight will be appreciated.

There seems to be error in CodeGenPassBuilder. I could not figure out how to fix this error

I read this issue to solve, so the directory become C:\Users\uwu\AppData\Local\Android\Sdk\ndk\23.0.7599858\toolchains\llvm\prebuilt\windows-x86_64\lib\clang\12.0.1\lib\linux\arm but still getting same error https://github.com/heroims/obfuscator/issues/7#issuecomment-1025939903

What i'm missing?

Can you upgrade llvm to 12.0.5 by any change?

compiling using

cd build
cmake -G "Ninja" -DLLVM_ENABLE_PROJECTS="clang" \
    -DCMAKE_BUILD_TYPE=Release -DLLVM_TARGETS_TO_BUILD="X86" \
    -DBUILD_SHARED_LIBS=On ../llvm
ninja

on macOS does not seem to compile LLVMObfuscator.so but anything else

if you want this to be cross-platform do not hardcode link_libraries("/usr/lib/libz3.so"). Perhaps add a dep requirement in the readme and if/else OS directive?

i have installed z3 via homebrew and it triggers the build: link_libraries("/opt/homebrew/lib/libz3.dylib")

however, I get lots of build warnings and errors half way.

.../Obfuscation/CryptoUtils.h:68:2: error: "Unknown endianness of the compilation platform, check this header aes_encrypt.h" #error

Hi, I've recently built this project and ran into the following issues:

• the line link_libraries("libLLVMTransformUtils.so") in Transforms/CMakeLists.txt results in /usr/bin/ld: cannot find -lLLVMTransformUtils and so LLVMObfuscator.so cannot be built.
• but then I tried to remove that line from Transforms/CMakeLists.txt and the test successfully ran, I've also checked the generated binaries and they seemed to be obfuscated fine.

I wonder how can the project be built successfully without that line, and does it affect the result if I remove it? Thank you.

按照看雪的教程编译win ndk，但是出现这个，我已经安装了 sudo apt install libz3-dev ,测试没有用。我又在 ~/llvm-toolchain/toolchain/llvm-project/llvm/lib/Transforms/IPO/CMakeLists.txt 中添加了，也没起到作用。

include_directories ("/usr/include/") link_directories("/usr/lib/x86_64-linux-gnu/")

I'm getting this error trying to compile on Win10. i have cmake and ninja installed. How can i fix it?

Hi bluesadi or 34r7hm4n ,

First of, I would like to thank you for your hardwork researching obfuscation methods with LLVM, or OLLVM as we all call. I have checked out your blog posts and projects, those are wonderful and insightful.

As I am currently working on OLLVM and researching about obfuscation. I think that we can work together to bring more ideas and improve the project. That is why I am writing you this as an invitation for collaboration.

Furthur details can be discussed directly to me in discord: luibo#0645.

If you're reluctant to have a conversation, you can try our RE challenge released at https://ctf.hackemall.live/. The CTF starts 00:00 01/01/2022 (UTC). The challenge is named crackme pls and authored by midas and luibo. The challenge is obfuscated using our customed version of OLLVM.

Looking forward to your reply.

P/S 1: I left comments in your latest blog post about MBA, but I feel the need to message you here because there is no direct contact methods and you may not read blog comments and the CTF is starting soon.

P/S 2: I welcome your CTF team to join the CTF also.

P/S 3: Have a wonderful new year.

我根据文章操作，"在toolchain/llvm-project/llvm/lib/Transforms/Obfuscation/中加入自己的代码" (Obfuscation没有这个文件夹，我直接把你的Pluto-Obfuscator里的文件夹及文件复制过去了)

然后python3 toolchain/llvm_android/build.py --no-build linux

最后报错：

实际上我试着把关于HelloWorld的添加的三行注释掉

#include "llvm/Transforms/Obfuscation/HelloWorld.h"

cl::opt RunHelloWorld("hlw",cl::init(false),cl::desc("Enable the HelloWorld pass"));

MPM.add(createHelloWorldPass(RunHelloworld));

但后面添加的的SplitBasicBlock，Flattening等等依然会报没有发现文件

另外我翻阅项目里的Pluto-Obfuscator\Pluto-Obfuscator-main\llvm\lib\Transforms\CMakeLists.txt

add_subdirectory(Obfuscation) 在看雪文章里并没有提及添加，我根据看雪文章步骤操作是否需要添加呢

首先当然是插件形式更加方便使用，其次是 Legacy Pass 目前已经废弃的事实 而且New Pass Manager并不难适配 这个Issue( https://github.com/bluesadi/Pluto-Obfuscator/issues/6 )里面也有提到过相关教程 我自己也尝试移植了一份(https://github.com/TheDivisibly/Pluto-Obfuscator/tree/NewPassManager_port) 经过测试除了Bogus 和 Trap 会出问题之外 别的 功能基本上都能正常在我的测试用例下面正常工作 除了参数配置需要额外考虑之外好像没有需要特别考虑的了

I build ollvm in Windows using MinGw. And merged llvm with ndk r23-c.

When i build my c++ project in android studio : ld: error: unable to find library -lgcc Trying to add -nostdlib but still error' ld: error: unable to find library -latomic

I'm using Pluto Obfuscator on NDK 23.2.8568313 . When using RandomControlFlow flag, it crashes and leaks memory to the max

Good Afternoon!

I have a particular use case that oddly MBAObfuscation doesn't fit - I'm working on seeing if I can add it myself, but figured I'd ask here for some insight in case its something I'm missing:

In cases where function calls accept integer parameters that are constant, like say the following function definition:

UINT32 Function( _In_ UINT32 Value, _In_ UINT32 ConstantValue )

With a callee say executing

Function( Variable, 0x41424344 );

One would expect that either the variable substituion or MBA obfuscation would inherently obfuscate the 0x41424344 value - However, even with the isa<CallInst>(I) enabled - IT oddly still misses it. Is there any particular reason for this?

RandomControlFlow is problematic in some cases.
