Detects vulnerable installations of Node.js and Bun based on software inventory data to identify exposure to CVE-2026-111497 (Node2Shell).
Detects the execution of two or more distinct Active Directory discovery, credential extraction, or coercion tools (such as NetExec, Kerbrute, noPac, PetitPotam, SoftPerfect Network Scanner, or Impacket scripts) on the same device within a 1-hour window.
Detects the execution of OpenConnect VPN clients on non-sanctioned devices followed within a 4-hour window by high-volume internal network connections across multiple ports indicative of network service discovery or pivoting activity.
Detects instances where the Apache web server spawns a shell process (sh, dash, bash) which subsequently executes common discovery or callback utilities (such as id, curl, wget, php, hostname, or uname), typically indicative of web application exploitation or remote code execution.
Detects processes that make outbound API calls to known Large Language Model (LLM) domains while simultaneously performing high-volume network connection attempts or scanning-like fan-out activity across multiple public IP addresses.
Detects web server processes (such as apache2, httpd, nginx, php-fpm) spawning a shell or curl process that performs LDAP queries using curl against URLs. This activity is indicative of Remote Code Execution (RCE) vulnerabilities being exploited against web applications to perform internal reconnaissance or LDAP enumeration.
Detects when typical discovery commands (whoami, id, uname, ipconfig) are executed under a web server or PHP process parent, potentially indicating post-exploitation activity following a web application compromise. The rule aggregates distinct commands within a 15-minute window to reduce false positives.
Detects a single external source IP reading secrets and configmaps across multiple Kubernetes namespaces in bulk within a 1-hour window, which may indicate reconnaissance or credential theft.
Detects the correlation of two or more distinct discovery tools or artifacts (such as SharpShares, NetScan, NetExec, ShareFinder, and specific nltest.exe domain trust commands) executed on the same device within a one-hour window.
Detects quick reconnaissance commands (such as whoami, id, uname, ipconfig) executed directly by a web server worker (e.g., PHP-FPM, Apache httpd) or via a shell child process of the web server worker, indicative of post-exploitation activity like php2shell.
Detects Windows process creation for Active Directory reconnaissance and Kerberoasting tooling (Rubeus, SharpHound, net group queries for domain admins, nltest) and noPac / Zerologon follow-on tooling associated with the INC and The Gentlemen ransomware intrusion chain.
Detects a suspicious behavioral sequence in AWS CloudTrail logs from external IPs using the Boto3 user agent. The sequence starts with caller-identity validation (GetCallerIdentity), followed by a high volume of secret reads (Secrets Manager) or cloud storage object reads (S3), indicating automated reconnaissance, credential theft, or data exfiltration.
Detects potential data exfiltration and credential hunting where an endpoint downloads a database backup using presigned URLs or cloud storage signatures within 6 hours of searching local files for API keys or private keys.
Detects web server processes (such as Apache, httpd, or PHP) spawning a Unix shell (sh, bash, dash) and executing discovery commands (such as id, hostname, uname) with output redirection to proof files or embedded in callback URLs via command substitution.
Identifies devices running Request Tracker (RT) applications, processes, files, or network services, and flags instances with vulnerable versions or specific CVEs (CVE-2025-61873, CVE-2026-41075, CVE-2026-41076, CVE-2026-6841, CVE-2026-44229, CVE-2026-44230, CVE-2026-44231) below version 5.0.10.
Detects a sequence of AWS API calls where an external IP first calls sts:GetCallerIdentity, followed by Bedrock model listing APIs, and subsequently IAM or account/trail discovery events within a short timeframe, indicating potential cloud reconnaissance or unauthorized access.
Detects outbound network connections to known ClickFix campaign domains or the execution of the finger utility connecting to public IP addresses.
Detects the execution of processes associated with virtualization platforms, hypervisors, virtual machine management utilities, and containerization technologies on Windows endpoints.
The detection identifies executable names related to Microsoft Hyper-V, VMware, Oracle VirtualBox, QEMU, Xen, Parallels, WSL, and container runtimes such as Docker and containerd.

Detects post-exploitation behavior where a PaperCut server Java process spawns local account creation or administrator reset followed closely by Active Directory enumeration on the same host, indicating potential post-RCE meterpreter activity.
Detects a PaperCut server Java process spawning a local account creation or local administrators group addition, followed closely by Active Directory domain or computer enumeration from the same host within a 30-minute window.
Detects a Python process spawning msiexec.exe followed by a high volume of LDAP connections (burst) from the same device within a 30-minute window, potentially indicating post-exploitation activity such as domain enumeration.
