.netrc

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?

.netrc

Plaintext credential file used by ftp, curl, and other tools for automatic login

What an attacker could do

This plaintext file stores login and password pairs for FTP, HTTP, and API endpoints used by curl and other tools, so exposure directly hands an attacker reusable credentials for those services.

How to defend it

Never store .netrc in web-accessible locations, set permissions to 600, prefer credential helpers or environment-based secrets over plaintext, and rotate any credentials that may have been exposed.
