7G Addon: Stop Aggressive Scanning for Uploads-Related Targets

Around the end of December 2019 and then now well into January of 2020, I’m seeing a massive spike in aggressive malicious scanning for uploads-related targets. In particular, there are massive numbers of requests for URL targets involving uploadify, plupload, and similar. Typical scans hitting upwards of 30K–50K requests per attack. Just relentless exploit scanning on steroids. Continue reading »

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).

2014 Micro Blacklist

Over the past several months, I’ve assembled a “micro” blacklist to keep some recent threats at bay. Eventually, this will be integrated into the next nG Blacklist, but for now I just wanted to post and share with anyone else who is actively monitoring their server logs and aware of the recent spike in malicious activity.

5G Blacklist 2013

Following up on much feedback (and this post), here is an update for the 5G Blacklist for 2013. As explained in the 2012 article (and elsewhere), the 5G Blacklist helps reduce the number of malicious URL requests that hit your website. It’s one of many ways to improve the security of your site and protect against evil exploits, bad requests, and other nefarious garbage. If your site runs on Apache and you’re familiar with .htaccess, the 5G is an effective […] 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 »

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. Continue reading »

Building the 5G Blacklist

Protecting your website is more important than ever. There are a million ways to do it, and this is one of them. In fact, it’s what I use to protect Perishable Press and other key sites. It’s called the 5G Blacklist, and it’s something I’ve been working on for a long time. The idea is simple enough: analyze bad requests and block them using a firewall/blacklist via .htaccess. Now in its 5th generation, the 5G Blacklist has evolved into a […] Continue reading »

4G Series: The Ultimate User-Agent Blacklist, Featuring Over 1200 Bad Bots

As discussed in my recent article, Eight Ways to Blacklist with Apache’s mod_rewrite, one method of stopping spammers, scrapers, email harvesters, and malicious bots is to blacklist their associated user agents. Apache enables us to target bad user agents by testing the user-agent string against a predefined blacklist of unwanted visitors. Any bot identifying itself as one of the blacklisted agents is immediately and quietly denied access. While this certainly isn’t the most effective method of securing your site against […] Continue reading »
