Fighting terrorism, one managed challenge at a time

Given the current explosion in viciously evil advocacy for genocidal anti-sematic terrorism, and its inevitable bleed-over to murderous anti-Americanism, I decided to add a CF firewall rule to annoy the worst-offending countries with a managed challenge. For good measure I added a few additional nefariously evil countries. I was sadly unable to find a way to include the diabolically depraved pro-Hamas wing of the U.S. democratic party, and its barbaric supporters.

Safeguarding Your Online Presence: Cloudflare’s Free DDoS Protection

Guest post written by AI (ChatGPT)

User: Write a blog post about DDoS protection using the Cloudflare free plan.

ChatGPT:

Introduction: Maintaining a secure online presence is of utmost importance in today’s digital landscape. However, the rising threat of DDoS (Distributed Denial of Service) attacks poses a significant challenge to the availability and security of websites and applications.

Cloudflare Bot Fight Mode

According to Cloudflare, “Bot Fight Mode is a simple, free product that helps detect and mitigate bot traffic on your domain”. It attempts to identify traffic from bots that are absent from Cloudflare’s good-bot list, and – unfortunately does not block them, but rather issues “computationally expensive” challenges to make them expend time and resources before moving forward with their potentially nefarious mission.

Blocking those pesky RSS feeds and Sitemaps

Every time I create a new post or page using WP, the post or page is automatically duplicated in an RSS feed – for example wppov.com/mynewpost/feed. It isn’t exactly an evil twin, just antiquated and – by 2023 standards – more troublesome than useful.

RSS feeds were popular and useful a decade or two ago, but not so much in 2023. These days feeds are more likely used for content scraping, data mining, and spamming. No thanks, I’d rather block this bad behavior.

Cloudflare Managed Challenge

I review my Cloudflare firewall rules infrequently – maybe every couple of years – so I didn’t notice immediately when early in 2022 CF retired their CAPTCHA (thus ending the Cloudflare CAPTCHA Kerfuffle – oh well, it was fun while it lasted) and deprecated their JavaScript Challenge in favor of their new, more advanced Managed Challenge.

Custom Security Header

As a precaution against distributed denial of service (DDOS) attacks, I allow access to my websites only through Cloudflare. Direct access – for example using my IP number – is not permitted. I put a bit of code in my htaccess file that checks to see if the Cloudflare IP Country header is present. That worked fine but would be pretty easy for a determined bad guy, gal, nonbinary person, or bot to defeat – especially since I posted here about it.

Recently CF added a Transform Rule feature. It consistently amazes me the great features that CF makes available on their free tier. Using a Transform Rule, I can create a custom, secret request header which I can then check for using htaccess. Something like this …

The Cloudflare CAPTCHA Kerfuffle Continues

In early 2020, Cloudflare switched from Google’s reCAPTCHA to Intuition Machines’ hCaptcha. It was a business decision – although CF made a ridiculously hypocritical attempt to excuse the switch as a moral imperative. hCaptcha is much less expensive for CF than the Google alternative, but hCaptcha provides a lesser user experience. The CF community was – and remains – unhappy about the switch. Read more The Cloudflare CAPTCHA Kerfuffle Continues

Attacks on WordPress in 2020

The Wordfence 2020 WordPress Threat Report notes more than 90 billion malicious login attempts on the 4+ million sites using Wordfence in 2000. Doing a bit of math, that’s about 60 malicious login attempts on every site every day. I’m not at all sure 60 is exactly correct, but it seems about right based on what I find in my Cloudflare firewall logs – and it’s a big number.
