Detects the execution of portable Impacket tools ('mini_imp'), including psexec.py, secretsdump.py, and ntlmrelayx.py. This activity is indicative of potential credential harvesting, remote service execution, or NTLM relay attacks, as observed in the MexicanMafia 'Operation Escaneo' campaign.
This rule detects the execution of Impacket toolkit modules (such as psexec.py, wmiexec.py, secretsdump.py) via EDR process events, as well as potential lateral movement patterns identified by NTLM authentication (Logon Type 3) to ADMIN$ or IPC$ shares. This combination of signals is indicative of credential dumping, remote service execution, or lateral movement using techniques often employed by the Impacket suite.
This rule detects the creation or modification of executable files (.exe or .dll) on hidden Windows administrative shares (e.g., ADMIN$, C$, D$, IPC$), followed by the execution of a process with the same file hash on a different host within a one-hour window. This behavior is indicative of lateral movement using SMB shares to stage and execute malicious payloads.
Detects network traffic over SMB targeting the SYSVOL or NETLOGON network shares that includes the transfer or reference of common executable file extensions. This behavior is indicative of an adversary attempting to stage malicious payloads for deployment via Group Policy Objects (GPOs), a common method for lateral movement and persistence.

Detects potential lateral movement activity associated with the SPECTRALVIPER actor by monitoring OneDrive.Sync.Service.exe for the initiation of named pipe connections. The detection specifically targets anomalous orchestration patterns using the XGU::Feature::Pivot Shadow module and XGU::Pivot::StartLink, which utilize named pipes for inter-process communication across systems.
Detects instances of the 'smbd' process executing from non-standard locations or initiating network connections on ports other than the default SMB ports (139, 445), which may indicate a rogue service, masquerading, or network pivoting activity.
Detects the execution of Python-based SMB server implementations commonly associated with the Impacket toolset. Impacket is frequently used by attackers to facilitate lateral movement, credential relay, and remote file manipulation.
Detects the execution of sc.exe with subcommands 'create' or 'start' where the command line includes a UNC path. This pattern is indicative of an adversary attempting to install or execute a service on a remote host to facilitate lateral movement.
This rule detects SMB traffic indicative of remote service creation over the SVCCTL named pipe, a pattern characteristic of tools like PsExec used for lateral movement and remote code execution.
This rule detects the use of the PSEXESVC named pipe during a write operation over the SMB protocol, which is indicative of lateral movement using the PsExec tool.
Detects network activity characteristic of the PsExec tool performing lateral movement. The rule monitors for SMB traffic directed at the ADMIN$ share, specifically looking for the creation or access of the 'PSEXESVC' service binary, combined with the use of the 'svcctl' named pipe, which is used by PsExec to remotely control services.

This rule detects network activity associated with lateral movement using Windows Management Instrumentation (WMI). It specifically looks for a DCE/RPC Bind request that targets the IWbemServices interface UUID, a common method for initializing remote WMI connections to execute commands on remote systems.
This rule detects a high volume of access attempts to the IPC$ administrative share from a single source IP address within a one-hour window. This behavior can be indicative of reconnaissance, lateral movement, or other malicious activities using SMB/Windows Admin Shares.
This rule detects a high frequency of successful network connections from a single device to multiple unique destination IP addresses within a one-hour window. The targeted ports (445, 139, 3389, 22, 21) are commonly used for remote administrative access, file transfers, and remote shell services, which are frequently leveraged by adversaries for lateral movement. The threshold of 3 unique targets in an hour may indicate automated scanning or credential brute-forcing activity across the network.
Detects evidence of common Impacket tool execution (e.g., psexec, wmiexec, smbexec, ntlmrelayx), unauthorized access to sensitive SMB administrative shares (ADMIN$, IPC$), creation of suspicious services often used for remote execution, and lateral movement via NTLM network logons.
This rule detects potential ransomware lateral movement patterns by correlating specific network connection attempts (SMB/RDP/RPC) with the observed creation of files having the '.prinzeugen' extension on the same host within a 2-hour window. This behavior is indicative of a ransomware strain propagating across the network and performing encryption.
Detects the execution of specific Python scripts associated with the FortiBleed campaign. These scripts include 'spray_da.py' for domain admin password spraying, 'smb_test.py' for SMB validation and lateral movement, 'spider.py' for Active Directory crawling, and 'ad_full_audit.py' for Active Directory auditing. Detection is based on the Python interpreter executing these specific script filenames.
Detects the use of the sc.exe utility to create a new service on a remote system by specifying a path using a UNC share. This behavior is indicative of lateral movement, where an attacker attempts to execute code on a remote host by installing a service via SMB/Admin Shares.
Detects the execution of sc.exe with subcommands 'create' or 'start' where the command line includes a UNC path. This pattern is indicative of an adversary attempting to install or execute a service on a remote host to facilitate lateral movement.
