This rule detects PowerShell commands that enumerate system, security, or virtualization-related artifacts. It specifically looks for the usage of WMI and PowerShell cmdlets (e.g., Get-Process, Get-WmiObject) to query for known analysis tools, debuggers, or virtualization software strings, which is a common behavior of malware attempting to identify and evade sandbox or analyst environments.
This rule detects PowerShell commands or script blocks that enumerate running processes and query WMI/CIM classes (such as Win32_ComputerSystem or Win32_BIOS) to identify indicators of virtualization, sandboxing, or the presence of security analysis tools. This behavior is indicative of anti-analysis and sandbox-evasion techniques, commonly used by threat actors like Kimsuky to verify their execution environment before proceeding with malicious activity.
Detects the creation of suspicious scheduled tasks using either schtasks.exe or PowerShell's Register-ScheduledTask cmdlet. The rule specifically looks for masquerading attempts involving names like 'StandAloneOneDriveUpdater-2626', the usage of AtLogOn triggers, and the execution of the binary 'Automata-20.exe'.
This rule detects potentially malicious command patterns involving PowerShell and the Windows Task Scheduler. It identifies suspicious uses of Microsoft Edge update task names, PowerShell commands executing encoded scripts, and specific external download patterns associated with potential dropper or downloader activity.
Detects persistence mechanisms used by a Golang RAT, specifically targeting the creation of a 'DailyFitnessTracker' registry value in the HKCU Run key using reg.exe or PowerShell, and the placement of 'FitnessMonitor.exe' into the Windows Startup folder.
Detects execution of APT36's RUSTYSHADE backdoor, typically delivered via a DriverInstaller executable or zip file, and specifically tracks downloads from Backblaze B2 storage buckets using PowerShell.
Detects the establishment of persistence by the RUSTYMOVE malware through the creation of a scheduled task via PowerShell. The rule specifically looks for a command line containing both 'Register-ScheduledTask' and the specific masqueraded name 'StandAloneOneDriveUpdater-2626', which mimics a legitimate OneDrive update process.
Detects the execution of PowerShell commands by the RUSTYMOVE tool intended to enumerate external removable storage devices (USB, SD, MMC, IEEE1394). The rule monitors for the concurrent use of Get-Volume, Get-Partition, and Get-Disk cmdlets with specific BusType filtering patterns.
Detects malicious scheduled task creation using names intended to mimic Microsoft Edge update tasks. The rule identifies suspicious process activity including the spawning of conhost.exe with headless flags, PowerShell commands with encoded arguments, and attempts to fetch external scripts from the known malicious typosquatted domain indiatodays.org, all of which are characteristic of APT36 (Transparent Tribe) activity.
This rule detects the execution of PowerShell commands that simultaneously perform reconnaissance for security analysis tools and virtual machine environment indicators. The presence of encoded, hidden, or non-interactive PowerShell flags in conjunction with these discovery actions is indicative of an adversary attempting to verify their execution environment to evade detection and analysis by security researchers or automated sandbox systems.

This rule detects a correlation between host-level reconnaissance activity using WMI (via PowerShell or WMIC) to query system information, followed by network exfiltration to a known C2 IP address over a specific URI within a 10-minute window.

Detects command-line activity associated with Monkey ransomware, specifically attempts to bypass AMSI (patching AmsiScanBuffer, targeting AmsiUtils), disable ETW (Event Tracing for Windows) monitoring, and add Microsoft Defender exclusions to evade detection prior to encryption.
Detects the execution of common Windows command-line tools (such as cmd, powershell, or wmic) being used to query system information related to security configurations, antivirus status, firewall status, or installed security products. This behavior is indicative of an adversary performing reconnaissance to understand the defensive landscape of a compromised host.
Detects obfuscated PowerShell commands that utilize XOR operations combined with byte array manipulation and common file writing methods. This pattern is frequently used by malicious scripts to deobfuscate and drop payloads to disk.
Detects the deletion of volume shadow copies using common Windows administrative utilities including vssadmin.exe, wmic.exe, diskshadow.exe, or through PowerShell WMI/CIM cmdlets. This behavior is frequently associated with ransomware and data destruction attacks aiming to prevent system recovery.
Detects ClickFix-style activity where a web browser or common application launcher spawns a terminal or PowerShell process to execute obfuscated, copied, or piped commands. This behavior often indicates a social engineering attack where a user is tricked into manually executing a malicious command script.
Detects the use of PowerShell cmdlets such as Invoke-WmiMethod, Invoke-CimMethod, Get-CimInstance, or Get-WmiObject to interact with the Win32_Process class for process creation on local or remote systems. This behavior is frequently associated with administrative activity but is also commonly used by adversaries for remote command execution and lateral movement.
