Heavy Scans for Low-Hanging Fruit
I’ve been working on developing the 8G Firewall. Digging through log files and crunching the data, the big new trend I’m noticing is heavy scanning for easy targets, low hanging fruit. Bad actors are looking for any little hidden files stashed on your server. Mostly PHP files, also ZIP and RAR files, and other file formats commonly used for compressing and archiving content. Basically, anything that might contain useful information (like login credentials, database backups, email addresses, etc.). Also, 99% […] Continue reading »
BBQ Firewall – Count Blocked Requests
BBQ Firewall is built to be powerful, lightweight, fast and flexible. It’s code base is kept super lean, leaving extra functionality out of core while supporting new features via simple addons. For example, this tutorial shows how to use an addon to display the total number of blocked HTTP requests on the plugin settings page. This can help you get a basic idea of the plugin’s effectiveness. Continue reading »

About nG Firewall
The nG Firewall is a carefully crafted set of security rules for Apache and Nginx servers. nG may be applied via your site’s public root .htaccess file, or added via server configuration file. Once added, 8G provides powerful server-level protection against a wide range of malicious requests, bad bots, automated attacks, spam, and many other types of threats and nonsense. It’s a lightweight yet super strong firewall that improves site security and peace of mind. Continue reading »
Block Random String Comment Spam
Recently WordPress sites have been getting hammered with random-string comment spam. The attackers are clever, using random text strings for every vector except the payload, which usually is the URL used for the comment’s Name link. But for these weird comment spams, the apparent payload is the email address. It’s the only part of the comment that’s not made up of random gibberish. Continue reading »
Domain-Based, Site Specific Email Addresses FTW
I use domain-based emails for 99% of my email activity. The other 1% is comprised of assorted 3rd-party email services and temporary slash disposable addresses (like for testing purposes and one-off sign-ups, etc.). I can tell you whole-heartedly based on 20+ years working online that domain-based email is THE WAY to go. Continue reading »
DIY Server Uptime Monitor
There are many free (and commercial) uptime monitoring services that will alert you if your server goes offline. These services are popular because it’s mission critical to know when your sites are down. The sooner you know about it, the sooner you can scramble to get everything back online. I’ve tried other scripts and services but nothing that met my specific needs: simple, secure, lightweight and blazing fast. So decided roll my own DIY server status monitor and share it […] Continue reading »
Redirect Stupid Bots to Existing Resources
In case you hadn’t noticed, I’m on another one of my posting sprees. Going through the past year’s worth of half-written drafts and collected code snippets, and sharing anything that might be useful or interesting. Here is a bit of .htaccess that brings together several redirection techniques into a singular plug-&-play code snippet. Continue reading »
Deleting Unused Online Accounts
Like many of you, I have been working online for years now, more than most. Over the course of the past 20 years, I have created accounts at hundreds and hundreds of websites. That includes all the work-related stuff, like web development, plus LOTS of social media sites, online services for everything from email to security monitoring. Not to mention all of the accounts created for mundane things like banking, utilities, Internet and phone service, and so forth. Continue reading »
Target User Agents and Reduce Spam via robots.txt
Your website’s robots.txt file probably contains some rules that tell compliant search engines and other bots which pages they can visit, and which are not allowed, etc. In most of the robots.txt files that I’ve looked at, all of the Allow and Disallow rules are applied to all user agents. This is done with the wildcard operator, which is written as an asterisk *, like this: User-agent: * This site’s robots.txt file provides a typical example. All of the allow/disallow […] Continue reading »
New WordPress Plugin: Simple Login Notification
New WordPress plugin! Simple Login Notification does one thing and does it well: sends an email alert whenever an admin-level user logs in to your site. I use this plugin on all of my sites to keep an eye on any unauthorized activity. Not that I’m expecting any, but if it does happen I definitely want to know about it. The plugin size is only 4 KB (zipped) with virtually zero impact on performance or anything else. Win win win, […] Continue reading »
Enabling ModSecurity (Updated)
For years, I’ve not used ModSecurity for any of my own sites. Way back when I first tried ModSecurity, there were just too many false positives, so I stayed away from it, opting instead to develop my own fast Apache/.htaccess firewall. But my web host now is telling me that ModSecurity is required on all of their managed VPS plans. Continue reading »
Protect WordPress Media Files
This is an experimental technique that I am playing with. It’s the simplest possible way that I could think of to protect all files in the WordPress Media Library using only Apache/.htaccess. I’ve been testing the code on an image-heavy site and so far there are no issues. So I want to put the code out there for others to test and hopefully provide feedback if anything less than perfect. It’s a super simple method that prevents media files from […] Continue reading »
Roll Your Own Simple Password Manager on macOS
I’ve tried 1Password and Dashlane, and several other popular password managers for both Mac and PC. It always seems to be the same thing: things start off great and then go downhill from there. For example, I was loving 1Password, and then it locked me out of my password file/account. Likewise for a couple of years Dashlane was great, but then they started making drastic changes like moving from standalone app to browser extension Web-based UI. The confusion involved with […] Continue reading »
Opt Out of Google FLOC for Site Visitors (One Line of Code)
Google has another new thing they are doing, called FLOC (Federated Learning of Cohorts). It’s used to — surprise — track user activity across websites. Opting out ideally is handled by the user, who can customize their browser settings to disable FLOC while surfing around the Web. Beyond configuring your browser to opt-out of FLOC, you can disable it on any website with a single line of code. Continue reading »
