.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 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. For example, requests for author=1 through some number, say, author=1000, may reveal the usernames for all associated users. With a simple enumeration script, an attacker can scan your site and obtain a list of login names in a matter of seconds. Continue reading »

OS X TotalFinder Alternatives

For years, I enjoyed the advanced Finder functionality provided by BinaryAge’s excellent app, TotalFinder. Mac’s native Finder enables users to navigate and manage their files, similar in concept to Windows File Explorer. Unfortunately, as explained in my rant about things that suck about Mac, TotalFinder no longer is compatible with Mac 10.11+. Fortunately there are plenty of decent alternatives to TotalFinder, even if you’re running the latest version of Mac OS X. Continue reading »

Use Strong Usernames for Better Security

Image courtesy of eChunks.com Here is a quick security tip for people using popular apps on the Web. That is, apps like WordPress that may be widely used and targeted by bad actors and/or automated scripts. It’s all about adding another layer of security by hardening admin-level usernames.. Every now and then, I get an email letting me know that someone has requested a password reset for one of my admin-level WordPress accounts. Usually, the email notifications are sent directly […] Continue reading »

Things that kinda suck about Apple/Mac

I dove into the world of Apple/Mac over five years ago. Overall I think it’s a huge step up from anything Windows related, but there are some things that I feel kinda suck about Mac OS X and Apple products in general. This post rounds up some of my thoughts, hopefully to help promote discussion and encourage some much-needed improvement. Continue reading »

What to do when your site gets hacked

Over the years, my sites have been hacked numerous times. Each hacking event was somewhat of a miserable experience at first, but ultimately educational and even enlightening. I’m not going to say that getting hacked was the best thing that ever happened to me, but it certainly wasn’t the end of the world. In this post, I want to share some important steps to take and things to keep in mind if and when you discover that your site has […] Continue reading »

Block revslider Scans

One of the most annoying, persistent scans I’ve seen in a long time are those hunting for the revslider vulnerability. In the five or so months since the exploit was discovered, many sites have been compromised. And based on what I’ve been seeing in my traffic logs, the risk is far from over. Apparently every 2-bit script kiddie and their pet hamster wants a piece of the “revslider action”. Continue reading »

Protect Against Malicious POST Requests

Whether you like it or not, there are scripts and bots out there hammering away at your sites with endless HTTP “POST” requests. POST requests are sort of the opposite of GET requests. Instead of getting some resource or file from the server, data is being posted or sent to it. To illustrate, normal surfing around the Web involves your browser making series of GET requests for all the resources required for each web page. HTML, JavaScript, CSS, images, et […] Continue reading »

(Please) Stop Using Unsafe Characters in URLs

Just as there are specifications for designing with CSS, HTML, and JavaScript, there are specifications for working with URIs/URLs. The Internet Engineering Task Force (IETF) clearly defines these specifications in RFC 3986: Uniform Resource Identifier (URI): Generic Syntax. Within that document, there are guidelines regarding which characters may be used safely within URIs. This post summarizes the information, and encourages developers to understand and implement accordingly. Continue reading »

expose_php, Easter Eggs, and .htaccess

A reader recently brought to my attention a reported vulnerability on servers running PHP. It’s been known about for eons, but it’s new to me and it involves easter eggs in PHP so I thought it would be fun to share a quick post about what it is and how to prevent leakage of sensitive information about your server. It only takes a moment to disable the easter-egg information, should you decide to do so. Continue reading »

PayPal Phishing Spam

Just a heads up to anyone else getting the occasional PayPal phishing spam.. Usually it’s pretty easy to spot one of those crafty phishing emails, just hover over any links before clicking to view the real URL in the status bar. You know, the link says something like, “click here to restore your PayPal account,” but you know that’s garbage and could easily prove it by checking the actual link URL, which is usually something completely bonkers, like: Continue reading »

Switching from PC to Mac

I finally made the switch from PC to Mac. My previous machine was an old Sony Vaio purchased in 2005. It was top of the line then, and actually worked great until about a year ago, when it inevitably began dying a slow, complicated death. The time to finally buy a new computer was fast approaching..

Is it Secret? Is it Safe?

Whenever I find myself working with PHP or messing around with server settings, I nearly always create a phpinfo.php file and place it in the root directory of whatever domain I happen to be working on. These types of informational files employ PHP’s handy phpinfo() function to display a concise summary of all of your server’s variables, which may then be referenced for debugging purposes, bragging rights, and so on. While this sort of thing is normally okay, I frequently […] Continue reading »

How to Protect Your Site Against Content Thieves (and Other Scumbags)

Stolen content is the bane of every blogger who provides a publicly available RSS feed. By delivering your content via feed, you make it easy for scrapers to assimilate and re-purpose your material on their crap Adsense sites. It’s bad enough that someone would re-post your entire feed without credit, but to use it for cheap money-making schemes is about as pathetic as it gets. If you’re lucky, the bastards may leave all the links intact, so at least you […] Continue reading »
