Update the NTLM downgrade registry paths
 2020-04-07 18:13:29 +02:00
Maxime Thiebaut 73a6428345 Update the NTLM downgrade registry paths 
Recent windows versions rely on the ["MSV1_0" authentication package](https://docs.microsoft.com/en-us/windows/win32/secauthn/msv1-0-authentication-package). Production environment tests have shown that NTLM downgrade attacks can be performed as detected by this rule although some of the registry keys are located in an "Lsa" subkey ("MSV1_0"). This commit introduces additionnal wildcards to handle these cases to ensure the previous detection rules are still included.

Add AD User Enumeration
 2020-03-31 10:56:48 +02:00
Maxime Thiebaut 8dcbfd9aca Add AD User Enumeration 
When the "Read all properties" permission of a user object is set to be
audited in the AD, an event of ID 4662 (An operation was performed on an
object) is triggered whenever a property is accessed.

This rule detects these events by flagging any non-machine
`SubjectUserName` (i.e. another user) which accesses an object of the
`User` AD schema class.

Advantages of this rule include the detection of insider-enumeration
through automated tools such as BloodHound or manually through the usage
of the PowerShell ActiveDirectory module. Although this rule qualifies
as a medium severity one, this event could be qualified as high/critical
one if flagged on non-used canary user-accounts.

False positives may include administrators performing the initial
configuration of new users.
