7G Addon: Stop Aggressive Scanning for Uploads-Related Targets

Just relentless exploit scanning on steroids. Continue reading »

Remove or Hide File Extension with .htaccess

A common question I get is how to change or hide file extensions using .htaccess. Apparently search engines prefer “pretty” permalink URL structures over query-strings and file extensions. This is one reason why WordPress provides an SEO-friendly permalink option for URLs; because it is preferred over the default plain query-string based format. From the Permalinks settings screen in the WordPress Admin Area: Continue reading »

ALL Security is Security Thru Obscurity

[ Stormtroopers Keeping Things Secure. ]

Difference between mod_alias and mod_rewrite

Most of the redirect techniques provided in my stupid .htaccess tricks article all use Apache’s alias module, mod_alias. You can also use mod_rewrite to redirect URLs. The main difference is that, with mod_alias, the server is responding to the client request with a redirect, so the client immediately is sent to the new location. Conversely, with mod_rewrite, the server simply returns the new content, so the client is not actually redirected anywhere. This makes mod_rewrite more advantageous because it happens […] Continue reading »

Blocking the “ReallyLongRequest” Bandit

[ Sneaky Bandit ]

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 »
