fwhunt scan

Pemindai Komunitas FWhunt

Alat untuk menganalisis firmware UEFI dan memeriksa modul UEFI dengan aturan FWHunt.

Dependensi

Rizin (v0.6.2)

Instalasi

Pasang dengan pip (diuji pada python3.6 dan di atas):

 $ python -m pip install fwhunt-scan

Instal secara manual:

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

Contoh

Dengan skrip

Analisis/Pindai Modul terpisah:

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

Pindai seluruh gambar firmware:

 $ 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

Dengan Docker

Untuk menghindari memasang dependensi, Anda dapat menggunakan gambar Docker.

Anda dapat membangun gambar Docker secara lokal sebagai berikut:

 docker build -t fwhunt_scan .

Atau tarik gambar terbaru dari GHCR.

Contoh Penggunaan:

 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

Semua langkah ini diotomatisasi dalam skrip fwhunt_scan_docker.py :

 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

Contoh Penggunaan Dasar:

 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 ())

Pada platform Linux, Anda dapat lulus gumpalan untuk analisis alih -alih file:

 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
