Identifying Unknown Scripts

Identifying Unknown Scripts

After inserting the osano.js into the head of your website, Osano will begin automatically discovering and reporting the full URL of the scripts attempting to load on your site. It will also discover and report on specific cookies placed on your site. 

Osano keeps a curated list of script and cookie rules and their classifications for reference and will provide classification suggestions for scripts and cookies that we have seen before. 

NOTE: Script and cookie suggestions are merely RECOMMENDATIONS based on common classifications and use cases. They may not apply to your organization, so it is best to double-check each recommendation as it relates to your org's use of scripts and cookies before accepting its classification. 

Scripts/cookies with no suggested classifications or rules associated with them will read "Unknown" in the classification dropdown. This means we did not have enough information on this script or cookie to recommend a classification, and it must be filled in manually. 


Suggestions for Researching and Identifying Scripts and Cookies

It's always helpful to keep track of the tools you are using on your site, but there are times when you may not know what a particular script is or does. In that case, here are some suggestions for researching and identifying unknown scripts. 

Option 1: Check your site

  • Example: (In Chrome / Firefox / Edge) 
  • Go to your website in an Incognito/Private window. 
  • If possible, turn OFF third-party cookie blocking.

  • Right-click on your screen and open your "Developer Tools" by clicking "Inspect" or "Developer Tools." 
  • Click on the "Network" tab. 
  • Isolate JS or javascript 

  • Navigate to your site.
  • Now you will see a list of the scripts loading on your homepage. You can click around on the site to load more scripts as well as navigate to different pages. Note: It is doubtful that you will identify EVERY script on your site this way, but this gives you a starting point.
  • Here, you can search for keywords using the filter, and you can see things like the full script and the referrer or initiator. This MAY provide useful information when it comes to classifying scripts. 


Option 2: Your search engine is your friend

  • If you cannot identify your script in the developer tools or cannot find a script on your page, we recommend turning to your search engine of choice and looking up the root domain of the script itself. 
  • Example: https://snap.licdn.com/li.lms-analytics/insight.min.js
  • In this case, searching for snap.lincdn.com redirected me to https://px.ads.linkedin.com/
  • Now I know that this script is set by Linkedin and is an ad pixel.
