UPDATE 2014-08-07: Websense emailed me to say that the site has been reviewed and found to be safe. It may take some time for all of their products to receive the updated classification.

Quite a few emails and IRC messages hit my screen today about being blocked by Websense products. The report on Websense’s site claims shows that the site is part of a bot network: The URL analyzed is currently compromised to serve malicious content to visitors.

Here are some screenshots from the report:

I reached out to Websense on Twitter and via their site. In the report I sent to them, I explained how the site works, gave them a link to the FAQ, and directed them to several blog posts from this site about This response from Websense hit my inbox late today:

Here’s what I know:

  • The application that serves up the icanhazip services is not compromised
  • The virtual machine on which the application resides is not compromised
  • The application is returning valid data with no evidence of serving malware

If Websense wishes to claim that the site is being used by malware, I can certainly believe that. However, if they claim the site is serving malicious content or actively participating in attacks in any way, I’ve found no evidence that supports that claim.

I’ll be reaching out to Websense again for additional details and to clear up the report listing on the website. If anyone knows of a way for me to identify this malware traffic and block it from accessing, please let me know. My GPG key is available.
