Hi @ahmedamer ,

have you or someone on the team perhaps turned on the Defender for Endpoint deception features?

 

You can check the setting for Deception by going to your XDR dashboard > Settings > Endpoints > Advanced features and scroll to find the setting for  “Deception” towards the bottom of the features list.

 

if it’s on, you can confirm that the user you’re seeing is apart of the deception identities by scrolling a bit more on the endpoints menu for the “Deception rules” tab under the Rules header. There may just be one Default rule there. Click it and you should see a list of deception identities.

 

see more here: Configure the deception capability in Microsoft Defender XDR 

 

Best,

Dylan
