Carbon Black Cloud: Alerts page searching on device_name field containing hyphens-dashes returns additional alerts for other device names containing hyphens-dashes.

Products

• Carbon Black Cloud Endpoint Standard (formerly Cb Defense)
• Carbon Black Cloud Enterprise EDR (formerly Cb Threathunter)

Issue/Introduction

Searching the Alerts page for device_name: AAA-XYZ returns alerts for any device_name ending in "-XYY" (i.e. BBB-XYZ, CCC-XYZ, etc)

Environment

• Carbon Black Cloud Console: All versions
• Carbon Black Cloud Sensors: All versions

Cause

This is functioning as designed. The alerts page uses Elasticsearch as underlying search engine. This engine requires special characters be escaped, including device_name field

Resolution

1. To achieve the desired result, place the name of the device in double-quotes as so:

alerts query ->  device_name:"AAA-XYZ"

will only return alerts for AAA-XYZ

 

Additional Information

The Investigate page's device_name does NOT need escaping, so it is different behavior (due to a different search engine) than the Alerts page.
