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?
owa
Microsoft Outlook Web Access
What an attacker could do
Reaching the Outlook Web Access endpoint confirms an Exchange server is internet-facing and exposes the login portal to credential stuffing and password spraying, plus targeting of ProxyLogon/ProxyShell mailbox-takeover chains.
How to defend it
Front OWA with MFA and conditional access, enforce account lockout against spraying, keep Exchange fully patched, and consider restricting external OWA access to a VPN or published-app gateway.
