XDR agent not triggering alerts in the managements console while blocking

Daniel_Itenberg — Sun, 24 Apr 2022 11:01:18 GMT

Hi, I have a rather peculiar issue(?) with one of my agents.

Said agent is working as intended, however it blocked a certain file form running under "Local Malware Analysis". which is fine, but I did not receive any alert nor incident in the management console.

while the end user received a notification that a file has been blocked, I received no such alert.

It happened only with one agent. for now at least.

Anyone encountered such behaviour?

Thanks

@Daniel_Itenberg Is the network connectivity on the endpoint working? Is it possible for you to upload the trapsd.log file?

Hi @Daniel_Itenberg this is certainly not an expected behavior. Assuming that the endpoint is built with the same configurations as the rest of your fleet with identical network access permissions, the endpoint should be able to reach to all the URL's listed here.

If this issue persists and/or if you are able to recreate the issue, please create a support ticket with the TSF and an extract of the alert data (see screenshot below on the retrieval process).

Hi @Daniel_Itenberg

please also make sure that there is no exclusion created that prevents some or all alerts to be shown on your incidents.

Ive seen a customer recently with the same issue and by mistake they created an exclusion with a too general filter that made alerts to be excluded, even they were still protected and malicous code blocked
