Detects creation of the PSEXEC key file. Which is created anytime a PsExec command is executed. It gets written to the file system and will be recorded in the USN Journal on the target system
Detects the creation of suspicious accounts similar to ANONYMOUS LOGON, such as using additional spaces. Created as an covering detection for exclusion of Logon Type 3 from ANONYMOUS LOGON accounts.
Detects the creation, login, and deletion of a user account over a predefined timeframe
This analytic detects the creation, deletion, or modification of the "ESX Admins" group in Active Directory. These events may indicate attempts to exploit the VMware ESXi Active Directory Integration Authentication Bypass vulnerability (CVE-2024-37085).
This analytic detects attempts to create an "ESX Admins" group using PowerShell commands. This activity may indicate an attempt to exploit the VMware ESXi Active Directory Integration Authentication Bypass vulnerability (CVE-2024-37085). Attackers can use this method to gain unauthorized access to ESXi hosts by recreating the 'ESX Admins' group after its deletion from Active Directory.
This analytic detects attempts to create an "ESX Admins" group using the Windows net.exe or net1.exe commands. This activity may indicate an attempt to exploit the VMware ESXi Active Directory Integration Authentication Bypass vulnerability (CVE-2024-37085). Attackers can use this method to gain unauthorized access to ESXi hosts by recreating the "ESX Admins" group after its deletion from Active Directory.
This analytic detects modifications to privileged groups in Active Directory, including creation, deletion, and changes to various types of groups such as local, global, universal, and LDAP query groups. It specifically monitors for changes to high-privilege groups like "Administrators", "Domain Admins", "Enterprise Admins", and "ESX Admins", among others. This detection is particularly relevant in the context of potential exploitation of vulnerabilities like the VMware ESXi Active Directory Integration Authentication Bypass (CVE-2024-37085), where attackers may attempt to manipulate privileged groups to gain unauthorized access to systems.
This rule detects the use of `System.DirectoryServices.AccountManagement` within PowerShell script block logs. This .NET namespace is commonly used to programmatically manage Active Directory security principals such as users, computers, and groups. Adversaries may use this method to create new domain accounts, modify existing ones, or manipulate group memberships to establish persistence or elevate privileges within an Active Directory environment.
