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 »

The Voice of the World Wide Web (Consortium)

Check out this sweet composition of aural styles discovered in the stylesheet for the W3C’s website: /* AURAL STYLES (via W3C) */ @media aural { h1, h2, h3, h4, h5, h6 { voice-family: paul, male; stress: 20; richness: 90 } h1 { pitch: x-low; pitch-range: 90 } h2 { pitch: x-low; pitch-range: 80 } h3 { pitch: low; pitch-range: 70 } h4 { pitch: medium; pitch-range: 60 } h5 { pitch: medium; pitch-range: 50 } h6 { pitch: medium; pitch-range: […] Continue reading »

Yahoo! Slurp too Stupid to be a Robot

I really hate bad robots. When a web crawler, spider, bot — or whatever you want to call it — behaves in a way that is contrary to expected and/or accepted protocols, we say that the bot is acting suspiciously, behaving badly, or just acting stupid in general. Unfortunately, there are thousands — if not hundreds of thousands — of nefarious bots violating our sites every minute of the day. For the most part, there are effective methods available enabling […] Continue reading »

Building the Perishable Press 4G Blacklist

Last year, after much research and discussion, I built a concise, lightweight security strategy for Apache-powered websites. Prior to the development of this strategy, I relied on several extensive blacklists to protect my sites against malicious user agents and IP addresses. Unfortunately, these mega-lists eventually became unmanageable and ineffective. As increasing numbers of attacks hit my server, I began developing new techniques for defending against external threats. This work soon culminated in the release of a “next-generation” blacklist that works […] Continue reading »

Thoughts
What's up with Plesk UI lately? Especially on Chrome it looks just awful, all kinds of broken. Come on Plesk devs get it together.
Things get stressful, I try to pray. Not always easy, but always helps to relax and regain focus.
Nice new speed checker at fastorslow.com.
Easy way to exclude certain tests from WP Site Health: Site Health Tool Manager
Excellent (and free) tool for getting tons of site SSL infos: whynopadlock.com
Everyone just stay home and hide forever. Brilliant idea.
