Google Ads Spreads

In short - "Sponsored" link redirects to malicious site, and boom 💥 I felt "OpenBLD" effect! DNS blocked for me browser-hijacking app which was distributed with Google Ads which named asxg4ken... Wow 💣, very unexpected and nice as I usually try to be more careful when surfing the internet.

In the ever-evolving OpenBLD ecosystem, the second quarter of 2023 has witnessed remarkable growth and some exciting changes., the service committed to minimizing the internet noise caused by advertising and tracking, has evolved to introduce cutting-edge features like Anycast/GeoDNS, DNS-over-HTTPS, and DNS-over-TLS.

New Features

This evolution has brought forth two new services: Adaptive (ADA) and Strict (RIC), which are set to replace A-BLD and BLD. But what sets them apart? It's time to find out.

Testing Phase

I've been testing these new services for over two weeks now, and I must say, they are impressive. For all OpenBLD users, I encourage you to give them a try. Here's how you can make the switch:

  • For DNS-over-HTTPS (DoH), replace with

  • For DNS-over-TLS (DoT), switch from to

  • For DNS-over-HTTPS (DoH), replace with

  • For DNS-over-TLS (DoT), switch from to

In a week or two, A-BLD will be fully merged with ADA, ceasing to exist as we know it. One server ( will be replaced by another ( for faster and more efficient service. Don't wait; start your testing today!


All of this growth and development would not have been possible without the incredible support we've received this year. OpenBLD is grateful for the backing from the following organizations:

Malvertising seems to be enjoying a renaissance as of late, whether it is from ads on search engine results pages or via popular websites. Because browsers are more secure today than they were 5 or 10 years ago, the attacks that we are seeing all involve some form of social engineering.

A threat actor is using malicious ads to redirect users to what looks like a Windows security update. The scheme is very well designed as it relies on the web browser to display a full screen animation that very much resembles what you'd expect from Microsoft...

Fake system update drops Aurora stealer via Invalid Printer loader

A Few days ago, Malwarebytes tread intelligence team discovered a new campaign that uses a fake Windows update to drop the Aurora stealer. The attack starts with a malvertising chain that redirects users to a website displaying a fake Windows update page. The page is designed to look like the real thing, with a full screen animation that very much resembles what you'd expect from Microsoft.


After discovering and researching the IoC from the article, all compromised domains were added to DNSBL 🎉

Part of lists you can download from Cactusd 🌵 repository.

I'm working on new OpenBLD DoH/DoT release with Anycast DNS, GeoDNS (Europe, Asia locations) functionality.

I think this or next month, I'll start the new faster DoH/DoT OpenBLD testing release with automatic identification of the closest server location continent and network route detection for OpenBLD clients.

You can fill this form in, after review I'll "ping" you with testing as soon as possible:


Let's make internet surfing faster and safer together. Peace ✌️

Few time ago I decided to move content from Nuxt3 to a Docusaurus blogging system.

Before I used Nuxt3 for the Labs blog which also hosted the main docs for the ecosystem infrastructure. Begin with current day, I decided to move main content to the Docusaurus blogging system on relevant domain.

Docusaurus it is a best choose for Service Project. With Docusaurus blogging features are powered by the blog plugin, we can use markdown files (or folders) in to the blog directory.

Thanks, Docusaurus, for this functionality and flexible content management system!
