Is SN Utils OnPrem safe?

Low risk

SN Utils OnPrem adds developer tools to ServiceNow pages and lets other installed extensions write ServiceNow records.

The extension adds scripting and navigation helpers to ServiceNow instances. Its background script accepts messages from any other installed extension and, using the user's ServiceNow session token, sends a PUT to the Table API with a table, record and field value supplied by the sender. This is intended for a companion extension, and web pages cannot reach it.

Where it sends data

Destinations our analysis observed SN Utils OnPrem contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.

  • <instance>.service-now.com

    SN Utils OnPrem sends data to <instance>.service-now.com. No other extension we have analysed sends data here.
