Environment
- Carbon Black Cloud Backend: 1.20 (as of December, 2023)
- Carbon Black Cloud Sensor: All versions
Symptoms
For example, this custom query for the user "system" does not filter:
process_username:system
Cause
There are a few syntax differences between the Data Forwarder custom query tool and the Investigate/Watchlist pages.
One of those is that the process_username is NOT tokenized in the Data Forwarder custom query.
So for this case, "system" will not be a match for, say, "NT AUTHORITY\SYSTEM"
Resolution
For the Data Forwarder, use wildcards to match the entire string as so:
process_username:*\\system
