Why It’s Important

Email is one of the most valuable IT systems where organization share their plans, sensitive documents, chats….and even passwords.

UnderDefense, in cooperation with the Computer Emergency Response Team of Ukraine (CERT-UA) participated in a series of Incident Response cases in H1’2022 and noticed that Russian hackers and Ransomware groups shifted their focus to breaking into E-Mail Systems (primary on Exchange and Zimbra).

In this specific case, CrowdStrike EDR was in place and spotted an initial foothold but missed other critical backdoors and TTPs which were later disarmed by the UnderDefense 24×7 MDR/SOC Team. And the attacker was eventually kicked out of the network.
