All the little .txt files you can put in the root directory of your website

The ones I know of: ads.txt humans.txt robots.txt security.txt This site makes use of robots.txt and humans.txt.

ALL Security is Security Thru Obscurity

ob·scure /əbˈskyo͝or/ adjective 1. not discovered or known about; uncertain. In the purely literal sense, the concept of obscurity applies to every transaction on the Web.

While browsing server logs, I kept seeing these super long request URIs that begin with “YesThisIsAReallyLongRequest…” and then the request string just keeps going for like 1 kilobyte worth of characters. Not just a few times, but many. In other words, somebody is going around and repeatedly hitting servers with gigantic-size requests. Probably to test server response using other people’s servers. Ummm, yeah kinda malicious. So I did some research and then blocked the “ReallyLongRequest” Bandit. Continue reading »
