API Ključevi

Za više informacija o API ključevima pogledajte:

GCP - API Keys Enum

OSINT tehnike

Google API ključevi se široko koriste od strane svih vrsta aplikacija koje koriste sa klijentske strane. Uobičajeno je pronaći ih u izvor kodu veb sajtova ili mrežnim zahtevima, u mobilnim aplikacijama ili jednostavno pretražujući regex-e na platformama poput GitHuba.

Regex je: AIza[0-9A-Za-z_-]{35}

Pretražujte ga, na primer, na GitHub-u sledećim putem: https://github.com/search?q=%2FAIza%5B0-9A-Za-z_-%5D%7B35%7D%2F&type=code&ref=advsearch

Proverite izvorni GCP projekat - apikeys.keys.lookup

Ovo je izuzetno korisno za proveru kojim GCP projektu pripada API ključ koji ste pronašli:

# 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

Kao što možda ne znate koje API-je su omogućeni u projektu, bilo bi zanimljivo pokrenuti alat https://github.com/ozguralp/gmapsapiscanner i proveriti šta možete da pristupite sa API ključem.
