fwhunt scan

Fwhunt社区扫描仪

用于分析UEFI固件和使用FWHUNT规则检查UEFI模块的工具。

依赖性

Rizin（v0.6.2）

安装

使用pip安装（在python3.6及以上测试）：

 $ python -m pip install fwhunt-scan

手动安装：

 $ git clone https://github.com/binarly-io/fwhunt-scan.git && cd fwhunt-scan
$ python setup.py install

例子

与脚本

分析/扫描单独的模块：

 $ python3 fwhunt_scan_analyzer.py analyze-module {image_path} -o out.json
$ python3 fwhunt_scan_analyzer.py scan-module --rule {rule_path} {image_path}

扫描整个固件图像：

 $ python3 fwhunt_scan_analyzer.py scan-firmware -r rules/BRLY-2021-001.yml -r rules/BRLY-2021-004.yml -r rules/RsbStuffingCheck.yml test/fw.bin

与Docker

为了避免安装依赖项，您可以使用Docker映像。

您可以在本地构建Docker映像，如下所示：

 docker build -t fwhunt_scan .

或从GHCR中获取最新图像。

使用的示例：

 docker run --rm -it -v {module_path}:/tmp/image:ro 
  fwhunt_scan analyze-module /tmp/image # to analyze EFI module

docker run --rm -it -v {module_path}:/tmp/image:ro -v {rule_path}:/tmp/rule.yml:ro 
  fwhunt_scan scan-module /tmp/image -r /tmp/rule.yml # to scan EFI module with specified FwHunt rule

docker run --rm -it -v {module_path}:/tmp/image:ro -v {rule_path}:/tmp/rule.yml:ro 
  fwhunt_scan scan-firmware /tmp/image -r /tmp/rule.yml # to scan firmware image with specified FwHunt rule

docker run --rm -it -v {module_path}:/tmp/image:ro -v {rules_directory}:/tmp/rules:ro 
  fwhunt_scan scan-firmware /tmp/image --rules_dir /tmp/rules # to scan firmware image with specified rules directory

所有这些步骤均在fwhunt_scan_docker.py脚本中自动化：

 python3 fwhunt_scan_docker.py analyze-module {module_path} # to analyze EFI module

python3 fwhunt_scan_docker.py scan-module -r {rule_path} {module_path} # to scan EFI module with specified FwHunt rule

python3 fwhunt_scan_docker.py scan-firmware -r {rule_path} {firmware_path} # to scan firmware image with specified FwHunt rule

python3 fwhunt_scan_docker.py scan-firmware --rules_dir {rules_directory} {firmware_path} # to scan firmware image with specified rules directory

基本用法示例：

 from fwhunt_scan import UefiAnalyzer

...
uefi_analyzer = UefiAnalyzer ( image_path = module_path )
print ( uefi_analyzer . get_summary ())
uefi_analyzer . close ()

 from fwhunt_scan import UefiAnalyzer

...
with UefiAnalyzer ( image_path = module_path ) as uefi_analyzer :
    print ( uefi_analyzer . get_summary ())

在Linux平台上，您可以通过BLOB进行分析而不是文件：

 from fwhunt_scan import UefiAnalyzer

...
with UefiAnalyzer ( blob = data ) as uefi_analyzer :
    print ( uefi_analyzer . get_summary ())

uefiscanner

 from fwhunt_scan import UefiAnalyzer , UefiRule , UefiScanner

...
uefi_analyzer = UefiAnalyzer ( module_path )

# rule1 and rule2 - contents of the rules on YAML format
uefi_rules = [ UefiRule ( rule1 ), UefiRule ( rule2 )]

scanner = UefiScanner ( uefi_analyzer , uefi_rules )
result = scanner . result
