clearbluejar/ghidrecompفكّ ترجمة الملفات الثنائية على دفعات باستخدام Ghidra من سطر الأوامر، مع توليد ملفات C لكل دالة، ورسوم بيانية للاستدعاءات، وتوقيعات BSim، ونتائج SAST اختيارية لأغراض البحث الأمني.
تقوم هذه الأداة المكتوبة بلغة بايثون والتي تعمل عبر سطر الأوامر بفك ترجمة جميع دوال الملف الثنائي وكتابتها في مجلد في ملفات C منفصلة:```mermaid
flowchart LR
a(filename ) --> b[ghidrecomp] a2[(Symbol Server)] --> b
b --> e(Ghidra Project Files) b --> output
subgraph output
subgraph decompilations direction LR i(func1.c) h(func2.c) f(funcB.c) end
subgraph callgraphs direction LR j(callgraph1.md) k(callgraph2.md) l(callgraphN.md) end
subgraph bsim-xml direction LR n(sig-md5-bin1.xml) m(sig-md5-bin2.xml) o(sig-md5-binN.xml) end
end
أو ملف `C` واحد وملف رأس مع `--cppexport`:```mermaid
flowchart LR
a(filename ) --> b[ghidrecomp]
a2[(Symbol Server)] --> b
b --> e(Ghidra Project Files)
b --> singlefile
subgraph singlefile
direction LR
s1(all_funcs.c)
s2(all_funcs.h)
end
الغرض الرئيسي من هذا هو استخدام عمليات التفكيك لأغراض البحث والتحليل. تعتمد الأداة على Ghidra في التفكيك وتتواصل مع Ghidra باستخدام jpype عبر pyghidra.
كل هذه الميزات يوفرها في النهاية Ghidra

استخدم ghidrecomp لتشغيل التحليل الثابت على الكود المُفكك باستخدام قواعد Semgrep.
ghidrecomp bins/clfs.sys.x64.10.0.26100.3624-7fc7ad.gzf-e38b94.gzf

### المخرجات```bash

يقوم فحص SAST بإنشاء مجلد sast/ داخل مجلد المخرجات الثنائية:```bash
$ tree ghidrecomps/bins/ls/sast/
ghidrecomps/bins/ls/sast/
├── semgrep.sarif
├── semgrep.exit
└── logs/
└── semgrep.stderr.log
- `semgrep.sarif`: نتائج بصيغة SARIF متوافقة مع أدوات الأمان
- `semgrep.exit`: رمز الخروج من عملية semgrep
- `logs/semgrep.stderr.log`: مخرجات الخطأ القياسية من semgrep
## مثال على توليد توقيع BSim
استخدم `ghidrecomp` لتوليد متجهات ميزات متوافقة مع Ghidra BSim. يمكن لاحقًا إضافة ملفات XML هذه إلى قاعدة بيانات BSim.

GHIDRA_INSTALL_DIR إلى موقع تثبيت Ghidra.ghidrecompللوظيفة فحص SAST، قم بالتثبيت مع التبعيات الاختيارية:```bash pip install 'ghidrecomp[sast]'
سيؤدي هذا إلى تثبيت Semgrep للتحليل الثابت. يمكنك أيضًا تثبيته يدويًا:```bash
pip install semgrep
PS C:\Users\user> [System.Environment]::SetEnvironmentVariable('GHIDRA_INSTALL_DIR','C:\ghidra_10.2.3_PUBLIC_20230208\ghidra_10.2.3_PUBLIC') PS C:\Users\user> pip install ghidrecomp
### Linux / Mac```bash
export GHIDRA_INSTALL_DIR="/path/to/ghidra/"
pip install ghidrecomp
تجنب تثبيت Ghidra وJava على جهازك باستخدام devcontainer.
استخدم .devcontainer في هذا المستودع. انقر فوق الزر أعلاه إذا كان VS code مثبتًا لديك. إذا كان هذا المفهوم جديدًا بالنسبة لك، اطّلع على: ghidra-python-vscode-devcontainer-skeleton الإعداد السريع والذي يشرح المزيد عن الحاويات التطويرية.
استخدم صورة المستودع المنشورة مع تثبيت Ghidra وJava مسبقًا.```bash docker pull ghcr.io/clearbluejar/ghidrecomp:latest docker run --user vscode --rm -it ghcr.io/clearbluejar/ghidrecomp:latest bash
