KnujOn We take the Internet's abuse and create solutions

Dear KnujOn members, friends and visitors,

This project will cease accepting samples from the public on 22 May 2018. The knujon.net will stop accepting email samples and the server will be shut down. The servers at coldrain.net will stop forwarding email. knujon.org will cease accepting new memberships and donations as of 8 March 2018. knujon.com will remain active to maintain historical information about the project but no sample data will be accepted. All currently held samples and all samples accepted up until 22 May 2018 will be processed.

This research was started by Dr. Robert Bruen and Garth Bruen in 2003. After 15 years we have reached clear fundamental conclusions concerning the management of the Internet, findings which are neither pleasing nor surprising. We have taken this work as far as we can at this stage. A final comprehensive report of KnujOn findings will be published and maintained at knujon.com.

We thank everyone for their dedication and participation in this project and hope you will join us when we start our next project which will be based on KnujOn findings. The details of this further research will be announced on knujon.com.



KnujOn.com, LLC was an independent abuse handler and Internet security research organization based in Boston, Massachusetts. KnujOn processed abuse data in the form of spam and other security threats to develop a clear picture of problems facing the Internet. KnujOn builds profiles of online criminal groups, evaluates the quality of Registrars and Internet Service Providers, issues WHOIS challenges, documents policy failures, developed policy initiatives, tested compliance mechanisms, issued reports to law enforcement, and educated the public about complex Internet security issues. We saw our role as one of assisting the ordinary Internet user in navigating the dense technical bureaucracy of the global network and augmenting public services in the face of rampant illicit electronic traffic. KnujOn provided abuse processing, user advocacy and common-sense policy development free of charge.

What is a Registrar?

Registrars are entities authorized by the Internet Corporation of Assigned Names and Numbers (ICANN) to sponsor domain names. Sponsorship of a domain name means it can be placed in the Domain Name System and effectively become a website. While there are hundreds of registrars, a monitory are responsible for the bulk of spam, malware and other abusive uses of domains. Some registrars have effective policies for blocking abuse, others tacitly permit it because it is a significant revenue source. ICANN tolerates the abuse at these registrars because domain fees and accreditation fees from spammy registrars provide ICANN with continuous income. Measuring the impact of of certain registrars can be difficult because some registrars have large portfolios which simply make their share of Internet abuse a statical normality, while others cater to illicit Internet activity. The cart to the left of Percents of abused domains by registrar is a raw summary the number of reported sites, but does not tell the whole story. For example, Godaddy has the #2 highest collection of spammed domains (at 12.6%) but they also have the largest portfolio of all the registrars. (More...)
