This is a powerful technique that combines the power of Apache with the flexibility of PHP. Enabling you to do things like log all unwanted traffic, send email reports for blocked requests, create a UI to display logged data, and just about anything else you can imagine. It’s an excellent way to keep a close eye […] Continue reading »

Block Greasy Uploads Scanner

Whether you’re running WordPress or not, your site may be getting hit by endless scanning for your site’s uploaded files and similar nonexistent resources. Specifically, the “Greasy Uploads Scanner” endlessly scans sites for nonexistent resources in the /uploads/ directory, even if the directory itself doesn’t exist. Just mindless scanning for all sorts of weird files. It steals your server resources and threatens your site security. We hates them. And we wants to block them. Continue reading »

WordPress .htaccess file

The WordPress core uses .htaccess for two things: Permalinks and Multisite. This means that .htaccess is only required if you have enabled either of these features. Otherwise, .htaccess is entirely optional for default WordPress installations. Beyond the WP core, many plugins also use the .htaccess file for custom directives involving rewrites, redirects, custom headers, file compression, and much more. In many cases, such plugins add their .htaccess rules to your .htaccess file automatically, behind the scenes. Continue reading »

.htaccess Cleanup

Once again I am cleaning up my sites’ .htaccess files. I do this from time to time to remove old redirects, refresh blacklists, and update security and SEO-related directives. It’s tedious work, but the performance and security benefits make it all worthwhile. This post shares some of the techniques that were added, removed, or replaced from .htaccess, and explains the reasoning behind each decision. I do this for the sake of reference, and hopefully it will give you some ideas […] Continue reading »

Stop WordPress from modifying .htaccess

By default, depending on file permissions, WordPress automatically will modify the contents of your site’s .htaccess file. It does this on several occasions, adding and/or updating the rewrite rules required for WP’s permalink functionality. This post explains how this works, why it can be dangerous, and how to stop it from happening. Continue reading »

6G Firewall

After three years of development, testing, and feedback, I’m pleased to announce the official launch version of the 6G Firewall (aka the 6G Blacklist). This version of the nG Firewall is greatly refined, heavily tested, and better than ever. Fine-tuned to minimize false positives, the 6G Firewall protects your site against a wide variety of malicious URI requests, bad bots, spam referrers, and other attacks. Blocking bad traffic improves site security, reduces server load, and conserves precious resources. The 6G […] Continue reading »

Protect Against Humans.txt Query-String Scans

I woke up this morning to the sound of thousands of 404 requests hitting the server. It’s sad that there are kiddies out there who have nothing better to do than buy some pathetic $50 script and then sit there like an imbecile harassing people for hours on end. But alas, that is the world we live in — fortunately it’s less than trivial to block the entire scan with just a few lines of good old .htaccess. Continue reading »

Set Up WordPress MultiSite on MAMP

In this tutorial, you’ll learn how to install and run WordPress MultiSite on a MAMP webserver. Running multiple sites from a single installation simplifies and streamlines administration, and serving it all from a locally installed version of MAMP gives you everything you need to develop your network of sites for the Web.

Run WordPress Locally with _AMP

To run WordPress on the Web, you need a domain name and web host. But you don’t need either of those things to run WordPress on your own computer. You need only to set up a local server environment that includes Apache, MySQL, and PHP. That may sound like a tall order, but thanks to packaged software bundles such as MAMP and WAMP, setting up a robust server environment on your computer is a relative breeze. Continue reading »

Blacklist Candidate 2012-11-13: Evil Scanner Edition

It’s been awhile since I’ve posted one of my Blacklist Candidate series articles. It’s always fun for me to talk (or write) about security related issues, especially when a quick slab of .htaccess can be used to take care of business. And that’s exactly what we have in this edition of the series, where I’m pleased to bring you Blacklist Candidate Number 2012-11-13: the “evil” scanner. Instead of scanning your site, collecting data, and moving on, Mr. 2012-11-13 continues to […] Continue reading »

6G Firewall 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 […] Continue reading »

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. Continue reading »

Case-Insensitive RedirectMatch

WordPress MultiSite Subdomains on MAMP

Developing WordPress sites on a local MAMP server provides flexibility, privacy, and security throughout the development process. Setting up a WordPress environment on MAMP is definitely worth the effort, especially if you’re building and testing multiple sites using WordPress’ built-in MultiSite functionality. The easiest and recommended way of setting up WordPress MultiSite is to use sub-directories. So when you create a new site named “business”, it will be located at http://localhost/business/. Here’s a mini-tutorial on how to use sub-domains for […] Continue reading »
