Detects a suspicious sequence of events involving the execution of 'setup.sh', the subsequent creation of a hidden file in temporary directories, and the deletion of specific architecture-named files (redtail.*). This behavior is indicative of a malware loader or droppers attempting to install and then remove traces of its components.

This behavior is indicative of a malware loader or droppers attempting to install and then remove traces of its components.
This rule detects the use of PowerShell or common command-line network tools (curl, wget) to download or interact with files containing references to WPPConnect or WhatsApp automation JavaScript libraries. It flags activity where the parent process is a common LOLBIN (Living Off the Land Binary) or originates from suspicious locations such as user temporary directories, which is indicative of malicious automated tooling or script execution.
Detects command-line execution patterns consistent with the SloppyRAT stager, specifically using IronPython to execute base64-encoded and zlib-compressed payloads from suspicious directories like AppData or Local. The rule looks for the simultaneous presence of encoding/compression indicators and execution primitives (subprocess or Popen).
This rule detects potentially malicious activity associated with removable media (USB drives) by identifying two distinct patterns: first, the creation of an 'autorun.inf' file on a removable drive followed by the execution of a script or executable from that same drive shortly after. Second, it identifies executables appearing on removable media that are launched across multiple distinct hosts within a one-hour window, which may indicate worm-like spreading or mass-malware distribution via portable storage.

This rule detects potentially malicious JavaScript files associated with known malicious patterns or suspicious 'preinstall' script behavior within Node.js environments. It monitors for the execution of specific suspicious filenames or the use of common Node.js package management tools (npm, yarn, etc.) in contexts suggesting code generation or build-time abuse.
Detects anomalous system reconnaissance activity performed using WMIC or PowerShell Get-WmiObject commands. The rule tracks distinct command-line executions per device and flags hosts where three or more unique reconnaissance commands are executed within a short timeframe, which is indicative of an adversary enumerating system configuration, hotfixes, or hardware details.
Detects the execution of known offensive security tools often used for lateral movement, credential dumping, and remote code execution, such as Impacket modules and the 'Invoke-TheHash' PowerShell suite, via common command-line interpreters.

Detects the execution of a Perl script named 'package_info.pl' with specific command-line arguments involving 'license.tmp' located in '/var/tmp/'. This pattern may indicate the execution of unauthorized tools, license bypass attempts, or potentially malicious scripts masquerading as legitimate license management utilities.
This rule detects potentially malicious command-line activity involving powershell.exe or mshta.exe that is initiated by a web browser process (chrome.exe, msedge.exe, firefox.exe, or iexplore.exe). It monitors for indicators such as encoded commands, usage of Invoke-Expression, download cradles, hidden window flags, and specific known IOCs, correlating these events with recent browser activity to identify potential drive-by download or browser-based exploitation attempts.

This rule detects suspicious process execution originating from web server applications (e.g., php-fpm, apache2, nginx). It looks for common shell interpreters or command-line utilities (e.g., bash, curl, python) triggered by these web server processes when they contain command execution function strings in their command lines (e.g., system, shell_exec, passthru), which is a common indicator of web shell activity or post-exploitation command execution.
Detects suspicious execution of PowerShell or Mshta spawned from Explorer.exe. It looks for specific malicious indicators including references to known malicious domains, PowerShell encoding flags, hidden window arguments, or Mshta HTTP requests, which are common patterns for fileless malware or dropper execution.
Detects the creation of a scheduled task using 'schtasks.exe' where the initiating process is a script interpreter such as 'mshta.exe' or 'powershell.exe'. This behavior is often associated with the execution of malicious payloads or the establishment of persistence.

Matches known malicious dlp.sh/dlp-docker.sh Terraform module scripts used in Coder registry supply chain attack (common, aider, rstudio-server, windows-rdp, zed variants)
This rule detects the execution of specific DLP-related shell scripts (dlp.sh, dlp-docker.sh) being invoked by Terraform processes. This pattern may indicate suspicious automated infrastructure configuration or an attempt to bypass security controls by leveraging IaC tools to execute scripts.
