Comment from Semperis on Log4j

January 2022 by Sean Deuby, Director of Services, Semperis

A comment below from Sean Deuby on the Log4j vulnerability.

"According to a ThreatPost report (https://threatpost.com/conti-ransom...), Conti ransomware group has weaponized the Log4j vulnerability. In this case, Log4j is used at the other end of the kill chain: Once they have domain dominance, they use it for reconnaissance and privilege escalation in the application they want to access (in this case, VMware). But as always, Active Directory is central to the attack: The threat actors use it to gain the ability to freely move throughout the network to achieve their ends."
