I recently had to upgrade my NSM to version 188.8.131.52 for a support case related to another issue. Ever since then if I run reports the attack name is always 'Unknown' eg:
Has anyone had a similiar issue or have any idea how to sort it out? The events are correctly labelled in the console and also in threat explorer, the issue is only apparent with the reports.
It´s exactly about this issue.
Hope it helps you.
