Display bbPress Posts without a Plugin

I recently redesigned my .htaccess site, htaccessbook.com. Before the redesign, I was using bbPress for the forum functionality. It worked okay for a few years, but along the way there were all sorts of really nasty bugs and important things breaking. It seemed like, no matter what, each updated version of the bbPress plugin caused serious problems, like replies not working, permalinks changing, and all sorts of other issues. Eventually, I got tired of spending hours after each bbPress update […] Continue reading »

So to help in that regard, this tutorial explains the basics of matching numbers with .htaccess, and then provides some useful examples that should get you there. Continue reading »

Examples of Nested Encoding

Typically malicious scans use some sort of encoding to obscure their payloads. For example, instead of injecting a literal script, the attacker will run it through a PHP encoding function such as base64_encode(), utf8_encode(), or urlencode(). So if and when you need to decode some discovered payload, you can use whichever decoding function will do the job. For example, base64_decode(), utf8_decode(), or urldecode(). Sounds straightforward, but let’s dig a little deeper.. Continue reading »

Stop User Enumeration in WordPress

This tutorial explains how to block user-enumeration scans in WordPress. As explained in greater depth here, user enumeration happens when some malicious script scans a WordPress site for user data by requesting numerical user IDs.

Redirecting Hash Fragments with .htaccess

During this year’s site redesigns, I noticed in the server logs some 404 errors for various WordPress comments. These 404 requests each involved a fragment identifier (i.e., character string beginning with a pound sign, #) being interpreted as its HTML entity hex equivalent, %23. It may not seem like a big deal, but these days every detail counts, so it’s wise to clean up as many 404 errors as possible. Thus, here is a simple .htaccess technique for redirecting hash-fragment […] Continue reading »

Apparently every 2-bit script kiddie and their pet hamster wants a piece of the “revslider action”. Continue reading »
