Why You Should Analyze Threat Actor TTPs

After years of analyzing threat actor behavior, it’s become clear that at any given time there are specific tactics, techniques, and procedures (TTPs) that are particularly prevalent. By analyzing and understanding these TTPs, you can dramatically enhance your security program.

Go into the queues, freeze the ones unrelated to your domain.  Block the person from Japan, if it's a single IP (which you seem to be saying).  If you blocked their ability to send to your Exchange Server, you wouldn't still be receiving e-mail (if it's from the same IP address).
