Splunk Enterprise Security

Splunk Enterprise Security: https://s3.amazonaws.com/alexa-static/top-1m.csv.zip is no longer working. Is there a new source for this file?

https://s3.amazonaws.com/alexa-static/top-1m.csv.zip is hard coded into Splunk Enterprise Security SA-ThreatIntelligence/default/inputs.conf but is no longer working (as of this past weekend). Anyone found a work-around or a new source for this file?

Error in Enterprise Security (ES):

msg="A threat intelligence download has failed" stanza="alexa_top_one_million_sites" status="threat list download failed after multiple retries"

@andygerber it looks like Alexa might have stopped distributing the top 1 million sites in a static way. That URI was valid in April (per https://web.archive.org/web/20160429064334/https://support.alexa.com/hc/en-us/articles/200461990-Can...) but https://support.alexa.com/hc/en-us/articles/200461990-Can-I-get-a-list-of-top-sites-from-an-API- no longer lists it.

I don't know of a workaround at this time. The web service to access data isn't free 😞

If you don't want to rely on the Alexa file being available, Cisco Umbrella made a version in the same file format in response. You can find it at http://s3-us-west-1.amazonaws.com/umbrella-static/index.html

Just disable the existing Alexa download entry in ES. Then do the following steps.

  1. Clone it
  2. Make the name like cisco_top_one_million_sites
  3. Leave the type as alexa
  4. Edit the description appropriately
  5. Paste the url as this link which is on the site linked above: http://s3-us-west-1.amazonaws.com/umbrella-static/top-1m.csv.zip
  6. Then save it and you have replaced it.

Well as of 1:49PM MST 11/22/16 the file https://s3.amazonaws.com/alexa-static/top-1m.csv.zip is once again downloadable. Not sure what is going on here....

Looks like they secretly brought it back?

Quantcast might be useful as a replacement if Alexa does wind up retiring it:

Thanks for the info. Of course, in a SHC the changes are a bit more complex than just editing via the GUI. Will push out a fix next time I do a cluster update.

well Splunk needs to provide next steps here; it's a default download in ES right now, so everybody is erroring out.

Thanks @andygerber, I filed a jira and added it to the known issues. For now you can disable the download in the threat intelligence downloads. http://docs.splunk.com/Documentation/ES/4.5.0/User/Configureblocklists#Threat_Intelligence_Download_...

After disabling it, I am still getting the warning in messages. Are there any alerts to disable aswell?

Thanks
