CVE-2020-0688 Microsoft Exchange Server Exploit
Detects the exploitation of CVE-2020-0688. The POC exploit a .NET serialization vulnerability in the Exchange Control Panel (ECP) web page.

Prerequisites
To forward events to SEKOIA.IO, please follow this guide to create an EventHubs namespace with an EventHubs that enable the data streaming on the hub.
Once the data streaming is configured, in your EventHubs, go to Setting > Shared access policies
.
Create a new policy with the option Listen
then copy the Connection string-primary key
.
Create a Storage accounts
or use an existing one. Go to Data storage > containers
and create a new container.
Then go to Security + networking > Access keys
and copy the key1 Connection string
Create the intake
Go to the intake page and create a new intake from the format Microsoft 365 Defender
.
Pull events
Go to the playbook page and create a new playbook with the Consume Eventhub messages module.
Set up the trigger configuration with the EventHub's Connection string-primary key
, the hub name, the consumer group, the storage's Connection string-primary key
and the container name.
Start the playbook and enjoy your events.
