Detects the creation of PHP files within the 'wp-content/uploads/elementor/forms/' directory of a WordPress installation. This behavior is highly suspicious as it often indicates an attempt by an attacker to deploy a web shell or other malicious script following successful exploitation of the Elementor plugin, which allows for arbitrary file uploads.
Detects the execution of known potentially malicious tools cplsupport.exe and wtass.exe with install parameters, or the creation of a Windows service associated with these filenames using sc.exe. This activity is indicative of service-based persistence or malicious software installation.
Detects instances where the Windows Remote Management host process (wsmprovhost.exe) is associated with the execution of specific suspicious files (config.toml, cplsupport.exe, or wtass.exe) within a short time window. This activity often indicates post-exploitation behavior or remote execution of secondary tools using WinRM.
Detects execution of PowerShell.exe initiated by cplsupport.exe with hidden window styles and non-interactive, no-profile flags, which is often indicative of obfuscated command execution or malicious script activity.
This rule monitors the software inventory for outdated versions of the PostgreSQL database server. It identifies installations where the major and minor versions are below the threshold for current security releases (e.g., v18 < 6, v17 < 11, v16 < 15, v15 < 19, v14 < 24). Running outdated software increases the risk of exploitation of known vulnerabilities.
Detects instances where common web server applications (e.g., Apache, Tomcat, IIS, Nginx) or Java runtime environments spawn suspicious child processes like command shells (cmd.exe, powershell.exe, sh, bash) or network utilities (wget, curl). This behavior often indicates exploitation of a web vulnerability, such as Remote Code Execution (RCE), allowing an adversary to execute commands or download further malicious payloads.
This rule detects potential command and control (C2) activity associated with the CurlRAT malware. It monitors for both the execution of 'curl' or 'curl.exe' processes with command lines containing known C2 domains, and network traffic originating from internal devices directed toward those same domains.
This rule detects potential reflective code injection or in-memory loading (fileless) where a DLL or PE image is loaded by mshta.exe or powershell.exe, but the module load event lacks a valid file path on disk (or indicates a device path). This behavior is often associated with the execution of malicious payloads such as the Amatera loader, where payloads are executed directly in memory to evade file-based security detections.
Detects attempts to tamper with Microsoft Windows Defender configuration, specifically by modifying exclusion paths via PowerShell cmdlets (Add-MpPreference, Set-MpPreference), direct registry modifications, or forced Group Policy updates. It also monitors for the disabling of Tamper Protection via registry and the creation of scheduled tasks designed to apply Defender exclusions.
This rule detects network connections or DNS queries to known phishing domains (typosquatted Microsoft login domains), DeadDrop Resolver domains, and suspicious HTML payloads served from common CDN/package hosting sites (e.g., unpkg.com, npmmirror.com, cdn.jsdelivr.net, yarnpkg.com). These patterns are indicative of initial access attempts via phishing or the secondary stage of malware C2 communication.
Detects suspicious executions of 'nslookup.exe' and 'svchost.exe' when triggered by the Windows LockAppHost process. This pattern is indicative of potential process injection or masquerading attempts by malicious actors using legitimate system processes as proxies for unauthorized activity.
This rule detects potential cryptocurrency mining activity where known miner executables (specifically XMRig) or malicious scripts/processes are masquerading as or being spawned by 'LockAppHost.exe' or 'LockAppHost14a02b.exe'. It also monitors for subsequent attempts by these processes to terminate security-related tasks or establish persistence via registry run keys.
Detects the execution of PowerShell commands that utilize base64-encoded strings, window style arguments for obfuscation, and subsequent decoding to reveal suspicious indicators such as network downloading commands or archive manipulation, indicative of potential fileless malware staging.
Detects unauthorized processes (e.g., cmd.exe, powershell.exe, node.exe) accessing sensitive web browser files like 'Login Data' or 'Cookies' in common browser directories. This behavior is indicative of credential theft or data exfiltration attempts.
Detects when a Node.js process initiates a low-level keyboard hook (WH_KEYBOARD_LL or WH_KEYBOARD) while running from common user-writable directories, which may indicate malicious keylogging activity by a suspicious process.
This rule detects the presence of 'winpty-agent.exe' or 'winpty.dll' in proximity to 'node.zip' or 'build.zip' files within common user-writable or temporary directories ('AppData\Local\Temp', 'AppData\Roaming', 'ProgramData', 'Users\Public'). This pattern is often associated with the staging and execution of malicious tools or command-line wrappers in non-standard locations, bypassing legitimate application installation directories.
Detects a suspicious sequence of activities where PowerShell downloads or extracts specific zip files (node.zip, build.zip) to staging directories, followed by the execution of associated binaries like node.exe, winpty-agent.exe, or winpty.dll from those same locations. This behavior is indicative of an adversary staging and executing tooling within temporary user directories.
Detects Node.js or related helper processes executing shell commands (cmd.exe, powershell.exe) or other processes where the execution involves the 'withCreateProcessUser' argument. This often indicates attempts to bypass execution restrictions or run malicious payloads by utilizing Node.js as an execution proxy within unconventional or temporary directories.
Detects network activity from infrastructure provisioner tools (Terraform, Coder) or shell processes attempting to connect to suspicious domains (e.g., coder-infra.com) that resemble legitimate infrastructure domains. This activity is indicative of credential theft, specifically targeting OIDC tokens, SSH keys, or authentication tokens during automated provisioning processes.
Detects the execution of python.exe or pythonw.exe from locations other than standard installation directories (C:\Python, C:\Program Files\Python), accompanied by the presence of associated DLLs (msvcp150/160.dll or python3xx.dll). This behavior is often indicative of portable Python environments being used for malicious script execution.
Detects access to sensitive credential and configuration files commonly used by developers and automated systems, such as AWS credentials, SSH keys, Docker configurations, NPM tokens, and Maven settings. Access to these files is a high-indicator of credential harvesting by malicious actors or stealer-type malware.
