.env

Security Researcher Detected: You might have ended up here because your site vulnerability scanner found something interesting. Hi! I'm a security engineer and I'm having a good time interacting with the people and bots that are interested in information security.

You will hopefully find this site is well-secured and I'm not interested in being hacked. I'm interested in learning about how people try to hack me, though.

What is this endpoint?

.env

A file where you can store your sensitive data like API keys, passwords, etc.

What an attacker could do

App environment files routinely hold database passwords, API keys, and secret tokens in plaintext. Reading one often hands an attacker full database access, cloud credentials, and the ability to impersonate the application.

How to defend it

Never web-serve dotfiles: block requests for .env and other hidden files at the web server or CDN, keep secrets out of the web root, and load them from environment variables or a secrets manager. Rotate anything that may have leaked.
