Brute-Force Login Drip Attack
I’ve been noticing a new strategy for brute-force login attacks: the slow, incremental “drip” attack. Instead of slamming a login page with hundreds or thousands of brute-force login attempts all within a few minutes, some attackers have been taking a more low-key approach by slowing down the rate of login attempts in order to bypass security measures. The “drip” brute-force attack is extremely annoying, and possibly dangerous if any of your registered users are using weak login credentials. This article […] Continue reading »

Use Strong Usernames for Better Security

Analyzing Weird 404 Search Engine Requests
Lately I’ve been getting a significant number of really weird 404 requests for one of my sites. At first I ignored them. Then upon closer inspection, I realized that the requests were reporting user agents like Googlebot, Bingbot, and other top search engines. So there was cause for concern. You don’t want legitimate search engines tripping over endless 404 requests that are completely unrelated to your site content. That gets into “negative SEO” territory, and should be investigated and resolved […] Continue reading »
Block D-Bag Database Exploits
Some douchebag has been scanning my sites for a variety of potential database exploits. My sites are secure, so there is no real security threat, but the scans are extremely annoying and waste my server resources.

So after collecting some data and experimenting a bit, I wrote a simple .htaccess snippet to block a vast majority of these pathetic database-exploit scans. Continue reading »

The Web Belongs to Everyone. If you feel the need to control or regulate something, […] Continue reading »
Block revslider Scans

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 »
