Hi all,
We've starting rolling out EMS5 to our users, and have deployed the ATP Sensor on our dc's. The daily reports are working as expected but we have yet to see an alert. I've tried the FAQ trick of running nslookup againest the DC but no joy. Anyone got an ways to trigger an alert within AATP?
Oh AATP has been running for about 5 days.

Hi,
The easiest way to generate an alert is to do DNS recon against the Domain Controller - which is protected by the AATP Sensor.
let me know if you require more information.
Thanks,
Itay

Are there any health alerts on the portal? if yes, what are they?

Hey Itay,
We have no errors in the workspace. I can see the senors are checking in..so i believe there is no communication issue. I can also see the reports are getting updated with current information.
I've tried a very basic nslooking recon process...with no joy. If you are able to provide a method that will trigger something happy to have a look at it.

I got a high priority alert after setting up AATP when I used this command: mstsc /v computername /remoteguard
My intention was to connect to another computer (where I have admin privileges) by remote desktop, but without exposing my credentials to that computer. AATP really got worried about me skating on my Kerberos ticket like that.

What happened? did it alert on Pass The Ticket claiming the ticket was stolen from your source computer to the remote host?

Thanks for letting me know, we will check if we can spot that as false positive...
(although technically you might say it's a benign true)

Hello!
Tried simulating the sensitive group alert but did not get any alert when adding users to domain admins etc... The actions are shown if searched the user from top right corner search bar but it does not alert in the timeline.
Why is that?

Hi @Mtee- ,
Suspicious modifications of sensitive groups requires learning period of 4 weeks per DC.
The detection relies on events audited on domain controllers. Make sure your domain controllers are auditing the events needed.
Do you see any data in the Modification to sensitive groups report?
Thanks,
Tali
