API Key Leaks
The API key is a unique identifier that is used to authenticate requests associated with your project. Some developpers might hardcode them or leave it on public shares.
Summary
Tools
- KeyFinder - is a tool that let you find keys while surfing the web!
- 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.
Exploit
The following commands can be used to takeover accounts or extract personnal informations from the API using the leaked token.
