Detects lateral movement (SMB, RDP, WinRM) performed by a host within 5 minutes of communicating with specific commercial LLM APIs. This rule targets behaviors indicative of automated lateral movement driven by an LLM-based C2, excluding common administrative tools, standard business hours, and frequently used processes.

This rule targets behaviors indicative of automated lateral movement driven by an LLM-based C2, excluding common administrative tools, standard business hours, and frequently used processes.
Detects instances where critical system processes (such as svchost.exe, lsass.exe, or w3wp.exe) spawn known command-line interpreters or script execution utilities (e.g., cmd.exe, powershell.exe, certutil.exe) which then initiate outbound network connections to common ports (445, 3389, 135, 5985, 5986, 1433, 80, 443) that are external to the local network. This behavior is often associated with lateral movement, command and control (C2) communication, or reconnaissance.
Detects successful network connections initiated by the ConfigurationRemotingServer.exe process. This binary is associated with Windows configuration remoting services and may be used for remote administrative tasks or unauthorized remote management activities.
Detects successful administrative logins to VMware ESXi, vCenter, or related VDI infrastructure (Horizon) by users who have recently performed a password or MFA reset. This pattern is indicative of a helpdesk-based social engineering attack (vishing) or credential compromise where the attacker regains account access and immediately pivots to critical virtualization management infrastructure to facilitate ransomware deployment.
Detects anomalous network connection attempts using DCOM (port 135) or WinRM (ports 5985/5986) that originate from external networks or exceed established internal baseline frequencies. This pattern is often indicative of lateral movement or remote administration abuse via WMI or WinRM.
Detects lateral movement activities involving the use of WMIC to remotely create processes or Schtasks to remotely create scheduled tasks. These techniques are often used by threat actors, including those associated with DragonForce and CRPx0 ransomware, to propagate across a network by executing commands on remote systems.
Detects lateral movement activity where a host identified as running the Langflow framework attempts to connect to internal MySQL (3306) or Nacos (8848) services while utilizing root credentials, potentially indicating an attacker pivoting from a compromised application server.
Detects lateral movement activity where a host identified as running the Langflow framework attempts to connect to internal MySQL (3306) or Nacos (8848) services while utilizing root credentials, potentially indicating an attacker pivoting from a compromised application server.
Detects potential lateral movement activity associated with the CRPx0 propagation technique. The rule monitors for WmiPrvSE.exe spawning unusual child processes (indicative of remote Win32_Process.Create execution) which are concurrently correlated with outbound network activity from the same host.
Detects lateral movement activity where a host identified as running the Langflow framework attempts to connect to internal MySQL (3306) or Nacos (8848) services while utilizing root credentials, potentially indicating an attacker pivoting from a compromised application server.

Detects anomalous remote interactive or network logons where the specific account and remote host/IP combination has not been observed in the previous 14 days. The rule correlates these new login events with subsequent process execution on the destination host within a short window (5 minutes) to identify potential lateral movement where an adversary uses valid credentials to log in and immediately execute commands.

This rule detects rapid, repetitive connection attempts (TCP SYN) from a source within the internal network to a set of high-value targets (SSH, HTTP, SMB, RDP ports) within the same internal network. Such patterns are indicative of lateral movement or internal network reconnaissance, often performed by adversaries pivoting through a compromised host to discover services on other internal systems.
