This rule detects potential execution of malicious files from removable media (e.g., USB drives). It monitors for a sequence of events where a removable drive is mounted, a file is subsequently created on that drive, and then that same file is executed within a short time window.

This rule detects potential remote command execution using Windows Management Instrumentation (WMI) via wmic.exe or PowerShell, as well as suspicious child processes spawned by the WMI provider host (wmiprvse.exe). It monitors for command lines utilizing the /node switch to target remote systems or invoking WMI methods to trigger execution, which are common patterns for lateral movement.

Detects outbound network connections to 'registry.npmjs.org' originating from 'node' or 'bun' processes. This behavior may indicate an attempt to exfiltrate data, interact with malicious packages, or perform credential harvesting via npm tokens during execution.

102
Detects the installation or execution of known remote access tools (RMM) from suspicious parent processes (browsers, archives) or from user-writable directories (Temp, Downloads). This behavior is characteristic of initial access and staging activities performed by ransomware operators or Initial Access Brokers (IABs). The rule excludes known IT-managed deployment paths and signed binaries used by the organization.

Detects several potentially malicious activities related to Active Directory Certificate Services (AD CS). This includes high volumes of failed requests (potential enumeration), requests for sensitive templates (privilege escalation), and potential impersonation attempts using Subject Alternative Names (SANs). These activities are associated with AD CS abuse techniques.

Detects remote file access (via SMB, named pipes, or TCP) to the Active Directory Certificate Services (AD CS) 'CertLog' directory. This directory contains the CA database (.edb), which holds issued certificates and archived private keys. Access to these files from a non-CA host is a strong indicator of an attempt to exfiltrate the CA database for offline certificate and private key recovery.
