A client had to roll out 100+ laptops and choose Intune for this. It wasn’t certain who was getting what laptop so the choice was made to use an admin account to enroll the devices before giving them to the user.

Intune has a Enroll Limit of 15 so after 15 you start having issues

In Intune you can actually setup Device Enrollment Managers who can actually Enroll 1000+ machines

  1. In Intune in the Azure portal, choose Device enrollment > Device enrollment managers.

  2. Select Add.

  3. On the Add User blade, enter a user principal name for the DEM user, and select Add. The DEM user is added to the list of DEM users.

googleapps[1]Recently I had a user get in contact with a problem, that they had received thousands of emails from different email address’ of nonsense. Sure enough after checking this was true. It seems that someone was bulk sending paragraphs of a book to this users , new email = new paragraph x 1000 + Interesting , was this just an email bomb or something else?

So sending emails from a book is a new way for spammers / attackers to get around the spam filter , they were sending from legitimate created Gmail/Yahoo address even though they where for email spams.

Upon investigation, the emails had stop being received about 2 hours before the user contacted me , any new emails were not coming through which means the user has hit gmails receiving limit https://support.google.com/a/answer/1366776?hl=en

Why?

This is a sign that the attacker has reset an account password somewhere and wants the email to notify you this has been done to get “lost” so the user doesn’t know he’s being attacked until its too late!

How to stop this?

You will need to purchase Google Apps Premium and enable the Post  Ini filter which can detect emails bombs
