User Account Management involves implementing and enforcing policies for the lifecycle of user accounts, including creation, modification, and deactivation. Proper account management reduces the attack surface by limiting unauthorized access, managing account privileges, and ensuring accounts are used according to organizational policies. This mitigation can be implemented through the following measures: Enforcing the Principle of Least Privilege - Implementation: Assign users only the minimum permissions required to perform their job functions. Regularly audit accounts to ensure no excess permissions are granted. - Use Case: Reduces the risk of privilege escalation by ensuring accounts cannot perform unauthorized actions. Implementing Strong Password Policies - Implementation: Enforce password complexity requirements (e.g., length, character types). Require password expiration every 90…
MITRE mitigation sourceESXi Administration Command
Adversaries may abuse ESXi administration services to execute commands on guest machines hosted within an ESXi virtual environment. Persistent background services on ESXi-hosted VMs, such as the VMware Tools Daemon Service, allow for remote management from the ESXi server. The tools daemon service runs as `vmtoolsd.exe` on Windows guest operating systems, `vmware-tools-daemon` on macOS, and `vmtoolsd ` on Linux.(Citation: Broadcom VMware Tools Services) Adversaries may leverage a variety of tools to execute commands on ESXi-hosted VMs – for example, by using the vSphere Web Services SDK to programmatically execute commands and scripts via APIs such as `StartProgramInGuest`, `ListProcessesInGuest`, `ListFileInGuest`, and `InitiateFileTransferFromGuest`.(Citation: Google Cloud Threat Intelligence VMWare ESXi Zero-Day 2023)(Citation: Broadcom Running Guest OS Operations) This may enable follow-on behaviors on the guest VMs, such as [File and Directory Discovery](https://attack.mitre.org/techniques/T1083), [Data from Local System](https://attack.mitre.org/techniques/T1005), or [OS Credential Dumping](https://attack.mitre.org/techniques/T1003).

- AN0646 · Analytic 0646 — Detects anomalous usage of ESXi Guest Operations APIs such as StartProgramInGuest, ListProcessesInGuest, ListFileInGuest, or InitiateFileTransferFromGuest. Defender perspective focuses on unusual frequency of guest API calls, invocation from unexpected management accounts, or execution outside of business hours. These correlated signals indicate adversarial abuse of ESXi administrative services to run commands on guest VMs.
