Detects evidence of persistence mechanisms associated with the StyleSmuggler implant. The rule monitors for malicious crontab entries and file system activity related to gvfsd-user, .gvfsd, and /tmp/.kw_ artifacts.
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 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.
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.
Detects the modification of the Print Spooler (Spooler) Windows service configuration via command-line registry utilities (reg.exe or regedit.exe). This activity may indicate an attempt to restore or re-enable the Print Spooler service, which is frequently targeted for disabling as a mitigation strategy against vulnerabilities like PrintNightmare.
Detects potential anti-forensic activities performed by malware, specifically the use of 'attrib.exe' to hide files and 'cmd.exe' with 'del /f /q' to forcibly remove dropped payloads. These actions are common indicators of a cleanup phase in a malware lifecycle to hinder analysis.
Detects execution of netsh.exe when launched from unexpected parent processes (tapctl.exe or openvpnserv.exe) from locations other than the standard System32 or SysWOW64 directories. This pattern is indicative of potential malicious activity or persistence via Netsh helper DLLs masquerading or executing via non-standard paths.
Detects instances where OpenVPN service binaries (openvpn.exe or openvpnserv.exe) spawn command-line interpreters (cmd.exe or powershell.exe) with suspicious command-line characters or potentially unbalanced quotes. This behavior may indicate an attempt to leverage OpenVPN for code execution or persistence, often seen in environments where VPN configurations are manipulated to run arbitrary scripts.
Detects instances where OpenVPN service binaries (openvpn.exe or openvpnserv.exe) spawn command-line interpreters (cmd.exe or powershell.exe) with suspicious command-line characters or potentially unbalanced quotes. This behavior may indicate an attempt to leverage OpenVPN for code execution or persistence, often seen in environments where VPN configurations are manipulated to run arbitrary scripts.
Detects instances where OpenVPN service binaries (openvpn.exe or openvpnserv.exe) spawn command-line interpreters (cmd.exe or powershell.exe) with suspicious command-line characters or potentially unbalanced quotes. This behavior may indicate an attempt to leverage OpenVPN for code execution or persistence, often seen in environments where VPN configurations are manipulated to run arbitrary scripts.
Detects suspicious file transfer and subsequent execution activity associated with the ScreenConnect (ConnectWise Control) remote access application, which may indicate exploitation of file-transfer vulnerabilities. The rule monitors for ScreenConnect processes dropping executable or script files to disk followed by the spawning of command interpreters to execute those files.
Detects suspicious activity associated with the exploitation of a vulnerability in N-central (CVE-2026-86218). The rule monitors for unauthorized child process spawning by N-central components, creation of files in the application directory consistent with web shells, outbound network connections indicative of command and control, and the creation of new local or service accounts for persistence.
Detects the creation or modification of specific dropper/loader files and service worker registration within WordPress directory structures (wp-content/plugins, wp-content/themes, wp-content/uploads). These files are often associated with the injection of malicious scripts (e.g., on-chain resolvers) to facilitate drive-by compromises by site visitors.
Detects suspicious activity associated with the exploitation of a vulnerability in N-central (CVE-2026-86218). The rule monitors for unauthorized child process spawning by N-central components, creation of files in the application directory consistent with web shells, outbound network connections indicative of command and control, and the creation of new local or service accounts for persistence.
Detects Terraform processes (init or apply) executed in conjunction with suspicious post-deployment indicators, such as references to '.terraform' folders, execution of automation scripts like 'dlp.sh' or 'dlp-docker.sh', or access to sensitive telemetry data external to typical infrastructure management.
This rule detects process command line arguments that include the string 'data.external.telemetry', which may indicate the use of specialized tools, telemetry collection agents, or unauthorized data exfiltration channels.
Detects execution of Coder-related processes or scripts where sensitive configuration parameters, such as database credentials or authentication tokens, are passed via command-line arguments. This behavior can lead to the exposure of credentials to other users or processes on the system through process listing.
Detects command line containing reference to the "::$index_allocation" stream, which can be used as a technique to prevent access to folders or files from tooling such as "explorer.exe" or "powershell.exe"
Detects a child process spawned by 'winrshost.exe', which suggests remote command execution through Windows Remote Shell (WinRs) and may indicate potential lateral movement activity.
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.
