Encoding & Decoding PHP Code

There are many ways to encode and decode PHP code. From the perspective of site security, there are three PHP functions — str_rot13(), base64_encode(), and gzinflate — that are frequently used to obfuscate malicious strings of PHP code. For those involved in the securing of websites, understanding how these functions are used to encode and decode encrypted chunks of PHP data is critical to accurate monitoring and expedient attack recovery.

Ron Paul 2012 WordPress Plugin

Update (2012/11/08): Well the elections are over and Ron Paul was not elected to be the next president of the United States. Deeper implications aside, the Ron Paul 2012 plugin is now discontinued. If you’re looking for a WordPress plugin to display a banner, button, or badge on your website, check out my new plugin Show Support Ribbon. I wanted to show support for Ron Paul on my WordPress website with a simple badge or button. Surprised at not finding any plugins for Ron Paul in the Directory, I decided to be the first. You can grab it here: http://wordpress.org/extend/plugins/ron-paul-2012/ […] Read more »

Media Temple (dv) 4.0 Migration & Optimization

About a month ago, I received an email letting me know that my host, Media Temple, is discontinuing their (dv) Dedicated Virtual 3.0-3.5 servers. Everyone hosted on the old servers must migrate to the new (dv) 4.0 servers. The friendly (mt) email says: The migration is a fairly simple process and you’ll have until early summer to complete it. Having now perfromed the migration, I can assure you that solid preparation is required to make it a smooth and “fairly simple process”. Based on experience, I suggest getting started on this asap rather than waiting “until early summer” to make […] Read more »

6G Beta

Since releasing the 5G Blacklist earlier this year, malicious server scans and bad requests have surged with more novel attacks than I’ve seen since first getting into this stuff six years ago. In other words, now is the time to beef up security and lock things down. If you’re into monitoring your server and knowing your traffic, you may be observing the same recent spike in malicious activity. In response to these attacks, I’ve been secretly working on the next generation of G-series blacklist, the inevitable 6G Firewall. Read more »

Add Google+ Share Button to Any Site

g+ Share button Word on the streets is that the new Google+ Share button is the best way yet to benefit from Google’s myriad social-media services and all-important search-engine. And Google makes it SO easy to add the new Share button to your website. This article explains what it is, where it fits in with all the other social-Google stuff, and of course how to add the g+ Share button to any site. Read more »

Blank Space / Whitespace Character for .htaccess

Working on the next version of the G-Series Blacklist, I needed a way to match a wide variety of UTF-8-encoded (hex) character strings. Those familiar with their site’s traffic will recognize this particular type of URI request string, which is typically associated with malicious server scanning, exploits, and other malicious behavior. As I explain in this post, pattern-matching and blocking the blank-space, or whitespace character in URL-requests is an effective way to improve the security of your website. Read more »

Case-Insensitive RedirectMatch

Cool trick that you may not have known about.. it’s possible to get case-insensitive matching with the powerful RedirectMatch directive. Normally, you would just write your redirect as something like this: Read more »

WordPress Add-on for 5G Blacklist

Ill requests and malicious scans have been spiking recently, to the point where server performance was really taking a hit. One scan in particular hammered the server with thousands of bad requests in just a few minutes. There are people out there with strong scripts and small minds that are constantly scanning sites for vulnerabilities, and much of what I’ve seen is aimed primarily at WordPress. Read more »

Redirect WordPress Date Archives with .htaccess

Restructuring a WordPress website may involve removing the subdomain from URLs/permalinks. For example, I recently removed the original WP-install subdirectory from Perishable Press to simplify site structure and optimize WordPress permalinks. There are PHP scripts and WP plugins that might work for this, but in most cases .htaccess is optimal when changing URL structure and redirecting traffic. Here’s a quick example to help visualize the concept: Read more »

Category Functions for WordPress

My previous theme sports the now-infamous colorized categories, which aim to help visitors navigate featured content. In addition to the colors, featured categories display contextually relevant navigation, popular posts, and related tags. It’s a great way to improve organization and get more of your content in front of the visitor. To make it happen, a variety of tasty WordPress code snippets are used, including versatile theme functions that enable getting the first category link, displaying sub-categories of the current category, displaying popular posts per category, related tags, and more. In this post, you get the entire collection, plucked directly from […] Read more »

WordPress Plugin: GA Google Analytics

Update (2012/11/17): the original “Google Analytics Plugin” has been renamed to “GA Google Analytics” to find a home in the WordPress Plugin Directory. I’ve joked that there a million different Google Analytics WordPress plugins available, but I’ve never been able to find one that’s just dead-simple, plug-n-play, and with clean code and markup, so I wrote my own that does just that: a no-frills way to add the new asynchronous tracking code to all pages on your WordPress-powered site.

Dynamic Go-to-Top Link

Instead of displaying a perpetual “go to top” link for every page, here’s a quick way to dynamically display the link only if the content height is greater than that of the browser window. So it’s there when you need it, not when you don’t. Just include the following snippet of jQuery with your design: Read more »

New Theme!

Yep, just when you thought I was moving on with my life, I spend another month on a new theme. My problem is that I tend to listen to criticism. And my previous theme received plenty of it. People just thought it was too much, too sloppy, too busy, too colorful, too ugly, too lame, and you get the idea. For the record, I think the Unicorner theme is fun and awesome, looking great and visually appealing on my iMac. I think if I would’ve spent more time testing and tweaking for PC/Win and other setups, the response would have […] Read more »

Welcome to the new site! So many changes I don’t even know where to begin.. I think for now the design is beta so I’ll hold off on a big lengthy explanation and just keep an eye on things for awhile..
