.ssh/authorized_keys

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?

.ssh/authorized_keys

SSH Authorized Keys

What an attacker could do

Reveals which public keys grant SSH access and their comments (often user@host), letting an attacker enumerate valid accounts and target the corresponding private keys or append their own key if write access is found.

How to defend it

Keep the .ssh directory outside the web root with mode 700, deny dotfile serving at the server level, and audit authorized_keys for unexpected entries.
