clearbluejar/ghidrecompDécompilez des binaires en lot avec Ghidra depuis la ligne de commande, en générant des fichiers C par fonction, des graphes d'appels, des signatures BSim et des résultats SAST optionnels pour la recherche en sécurité.
Cet outil Python en ligne de commande décompile toutes les fonctions d'un binaire et les écrit dans un répertoire sous forme de fichiers C séparés :```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
Ou un seul fichier `C` et fichier d'en-tête avec `--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
Le but principal est d'utiliser les décompilations pour la recherche et l'analyse. L'outil s'appuie sur Ghidra pour la décompilation et communique avec Ghidra à l'aide de jpype via pyghidra.
toutes ces fonctionnalités sont finalement fournies par Ghidra

Utilisez ghidrecomp pour exécuter une analyse statique sur du code décompilé à l'aide des règles Semgrep.
ghidrecomp bins/clfs.sys.x64.10.0.26100.3624-7fc7ad.gzf-e38b94.gzf
--sast
--semgrep-rules semgrep-rules/c/integer-wraparound.yaml
--semgrep-rules semgrep-rules/c/integer-truncation.yaml
### Ligne de commande avec un répertoire de règles personnalisées```bash
ghidrecomp /bin/ls --sast --semgrep-rules /path/to/custom/rules/
ghidrecomp /bin/ls --sast --semgrep-rules rule1.yaml,rule2.yaml
### Sortie```bash
Running SAST scanning...
Running semgrep with configs: ['semgrep-rules/c/integer-wraparound.yaml', 'semgrep-rules/c/integer-truncation.yaml']
Running semgrep command: /usr/local/bin/semgrep scan --metrics=off --disable-version-check --quiet --error --sarif --timeout 30 --no-git-ignore -c semgrep-rules/c/integer-wraparound.yaml -c semgrep-rules/c/integer-truncation.yaml /tmp/tmpXXXXXX/decomps
Semgrep scan completed successfully
L'analyse SAST crée un répertoire sast/ dans le dossier de sortie binaire :```bash
$ tree ghidrecomps/bins/ls/sast/
ghidrecomps/bins/ls/sast/
├── semgrep.sarif
├── semgrep.exit
└── logs/
└── semgrep.stderr.log
- `semgrep.sarif` : résultats au format SARIF compatibles avec les outils de sécurité
- `semgrep.exit` : code de sortie du processus semgrep
- `logs/semgrep.stderr.log` : sortie d'erreur standard de semgrep
## Exemple de génération de signature BSim
Utilisez `ghidrecomp` pour générer des vecteurs de caractéristiques compatibles avec Ghidra BSim. Ces XML peuvent ensuite être ajoutés à une base de données BSim.

GHIDRA_INSTALL_DIR sur l'emplacement d'installation de Ghidra.ghidrecomp avec pipPour la fonctionnalité d'analyse SAST, installer avec les dépendances optionnelles :```bash pip install 'ghidrecomp[sast]'
Cela installera Semgrep pour l'analyse statique. Vous pouvez également l'installer manuellement :```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
