API Keys

API 키에 대한 자세한 정보는 다음을 확인하세요:

GCP - API Keys Enum

OSINT techniques

Google API 키는 클라이언트 측에서 사용하는 모든 종류의 애플리케이션에서 널리 사용됩니다. 웹사이트 소스 코드나 네트워크 요청, 모바일 애플리케이션에서 찾거나 Github와 같은 플랫폼에서 정규 표현식을 검색하는 것이 일반적입니다.

정규 표현식은: AIza[0-9A-Za-z_-]{35}

예를 들어 Github에서 다음과 같이 검색하세요: https://github.com/search?q=%2FAIza%5B0-9A-Za-z_-%5D%7B35%7D%2F&type=code&ref=advsearch

Check origin GCP project - apikeys.keys.lookup

이는 발견한 API 키가 어떤 GCP 프로젝트에 속하는지 확인하는 데 매우 유용합니다:

# If you have permissions
gcloud services api-keys lookup AIzaSyD[...]uE8Y
name: projects/5[...]6/locations/global/keys/28d[...]e0e
parent: projects/5[...]6/locations/global

# If you don't, you can still see the project ID in the error msg
gcloud services api-keys lookup AIzaSy[...]Qbkd_oYE
ERROR: (gcloud.services.api-keys.lookup) PERMISSION_DENIED: Permission 'apikeys.keys.lookup' denied on resource project.

Brute Force API endspoints

프로젝트에서 어떤 API가 활성화되어 있는지 모를 수 있으므로, https://github.com/ozguralp/gmapsapiscanner 도구를 실행하고 API 키로 접근할 수 있는 내용을 확인하는 것이 흥미로울 것입니다.
