This detection rule identifies suspicious usage of Virtualbox technology, which adversaries may utilize to run malicious operations within a virtual environment, thereby evading traditional security measures. The rule specifically looks for the installation and operational commands associated with Virtualbox drivers, including 'VBoxRT.dll', 'VBoxC.dll', and 'VBoxDrv.sys', as well as VM lifecycle commands like 'startvm' and 'controlvm'. By detecting these command line activities, the rule aims to highlight potential misuse of virtualization software that could indicate malicious intent, especially when such tools are used on systems with no legitimate reason for their deployment. Given that the detection focuses on the command line context, it also allows for the monitoring of potentially unauthorized users attempting to register or start Virtualbox, enhancing security visibility around virtualization technology usage. However, the rule might yield false positives in environments where Virtualbox is legitimately employed for business purposes, necessitating careful validation of alerts to avoid unnecessary disruptions.
