Building the 3G Blacklist, Part 1: Improving Security by Exploiting Server Attack Patterns

[ 3G Stormtroopers (Blue Dream) ]

In this series of five articles, I share insights and discoveries concerning website security and protecting against malicious attacks. In this first article of the series, I examine the process of identifying attack trends and using them to immunize against future attacks. Subsequent articles will focus on key blacklist strategies designed to protect your site transparently, effectively, and efficiently. At the conclusion of the series, the five articles will culminate in the release of the next generation 3G Blacklist. Improving […] Continue reading »

Universal www-Canonicalization via htaccess

[ Universal www-Canonicalization via htaccess ]

During my previous rendezvous involving comprehensive canonicalization for WordPress, I offer my personally customized technique for ensuring consistently precise and accurate URL delivery. That particular method targets WordPress exclusively (although the logic could be manipulated for general use), and requires a bit of editing to adapt the code to each particular configuration. In this follow-up tutorial, I present a basic www-canonicalization technique that accomplishes the following: Continue reading »

Welcome to the Perishable Press “Blacklist Candidate” series. In this post, we continue our new tradition of exposing, humiliating and banishing spammers, crackers and other worthless scumbags.. Since the implementation of my 2G Blacklist, I have enjoyed a significant decrease in the overall number and variety of site attacks. In fact, I had to time-travel back to March 1st just to find a candidate worthy of this month’s blacklist spotlight. I felt like Rod Roddy looking over the Price-is-Right audience […] Continue reading »

How to Block Proxy Servers via htaccess

Not too long ago, a reader going by the name of bjarbj78 asked about how to block proxy servers from accessing her website. Apparently, bjarbj78 had taken the time to compile a proxy blacklist of over 9,000 domains, only to discover afterwards that the formulated htaccess blacklisting strategy didn’t work as expected. Here is the ineffective htaccess directive that was used: Deny from proxydomain.com proxydomain2.com Blacklisting proxy servers by blocking individual domains seems like a futile exercise. Although there are […] Continue reading »

Redirect WordPress Feeds to Feedburner via htaccess (Redux)

In a previous article, I explain how to redirect your WordPress feeds to Feedburner. Redirecting your WordPress feeds to Feedburner enables you to take advantage of their many freely provided, highly useful tracking and statistical services. Although there are a few important things to consider before optimizing your feeds and switching to Feedburner, many WordPress users redirect their blog’s two main feeds — “main content” and “all comments” — using either a plugin or directly via htaccess. Here is the […] Continue reading »

Custom HTTP Errors via htaccess

We all know how important it is to deliver sensible, helpful 404 error pages to our visitors. There are many ways of achieving this functionality, including the well-known htaccess trick used to locally redirect users to custom error pages: # htaccess custom error pages ErrorDocument 400 /errors/400.html ErrorDocument 401 /errors/401.html ErrorDocument 403 /errors/403.html ErrorDocument 404 /errors/404.html ErrorDocument 500 /errors/500.html ..and so on. These directives basically tell Apache to deliver the designated documents for their associated error types. Many webmasters and […] Continue reading »

Welcome to the Perishable Press “Blacklist Candidate” series. In this post, we continue our new tradition of exposing, humiliating and banishing spammers, crackers and other worthless scumbags.. Imagine, if you will, an overly caffeinated Bob Barker, hunched over his favorite laptop, feverishly scanning his server access files. Like some underpaid factory worker pruning defective bobble heads from a Taiwanese assembly line, Bob rapidly identifies and isolates suspicious log entries with laser focus. Upon further investigation, affirmed spammers, scrapers and crackers […] Continue reading »

Welcome to the Perishable Press “Blacklist Candidate” series. In this post, we continue our new tradition of exposing, humiliating and banishing spammers, crackers and other worthless scumbags.. Like many bloggers, I like to spend a little quality time each week examining my site’s error logs. The data contained in Apache, 404, and even PHP error logs is always enlightening. In addition to suspicious behavior, spam nonsense, and cracker mischief, this site frequently endures automated and even manual attacks targeting various […] Continue reading »

Welcome to the Perishable Press “Blacklist Candidate” series! In this first post, we begin a new tradition of exposing, humiliating and banishing spammers, crackers and other worthless scumbags.. Every Wednesday, I take a little time to investigate my 404 error logs. In addition to spam, crack attacks, and other deliberate mischief, the 404 logs for Perishable Press contain errors due to missing resources, mistyped URLs, and the occasional bizarre or even suspicious behavior of the search-engine robots. Whenever possible, I […] Continue reading »

How to Enable PHP Error Logging via htaccess

In this brief tutorial, I will show Apache users how to suppress PHP errors from visitors and enable PHP error logging via htaccess. Tracking your site’s PHP errors is an excellent way to manage and troubleshoot unexpected issues related to plugins and themes. Even better, monitoring PHP errors behind the scenes via private log is far better than trying to catch them as they appear at random visits. Thanks to the magical powers of htaccess, there is an easy way […] Continue reading »

Three Ways to Allow Hotlinking in Specific Directories

After implementing any of the hotlink-prevention techniques described in our previous article, you may find it necessary to disable hotlink-protection for a specific directory. By default, htaccess rules apply to the directory in which it is located, as well as all subdirectories contained therein. There are (at least) three ways to enable selective hotlinking: Place hotlink images in an alternate directory This method works great if your hotlink-protection rules are located in a directory other than the site root. Simply […] Continue reading »

There are many reasons for wanting to employ this technique, including: Share public resources from an otherwise private site Enable visitors to access content during site maintenance Testing and formatting of layout and design during development As a webmaster, I have used this technique on several occasions. This trick works great for allowing access to any […] Continue reading »

Creating the Ultimate .htaccess Anti-Hotlinking Strategy

[ Image: Illustration of two hands holding a glowing object ]

When I wrote my article, Stupid htaccess Tricks, a couple of years ago, hotlink-protection via htaccess was becoming very popular. Many webmasters and bloggers were getting tired of wasting bandwidth on hotlinked resources, and therefore turned to the power of htaccess to protect their content. At that time, there were only a couple of different hotlink-protection methods available on the internet, and the functional difference between them was virtually insignificant. All that was necessary for up-and-coming bloggers-slash-site-administrators to eliminate leaking […] Continue reading »
