Detects the execution of known Impacket relay tools such as ntlmrelayx and smbrelayx, which are commonly used by adversaries to perform NTLM relay attacks to gain unauthorized access or execute code on remote systems.
Detects the execution of known PetitPotam exploitation tools or the use of command line arguments related to EFS RPC functions (e.g., EfsRpcOpenFileRaw) used to coerce authentication via NTLM reflection.
Detects the use of the 'net.exe' or 'net1.exe' command-line utilities to mount a local SMB share using loopback addresses (127.0.0.1 or localhost) with the '/tcpport' argument. This pattern is indicative of attempts to exploit CVE-2026-24294 to bypass NTLM authentication protections through local reflection or relay attacks.

This rule detects the use of 'net.exe' or 'net1.exe' to configure a non-standard SMB port, which is a technique often used for NTLM reflection and relay attacks. By specifying an arbitrary port for SMB traffic, an attacker may attempt to bypass standard network filtering or establish a listener to intercept authentication requests.

This pattern is indicative of attempts to exploit CVE-2026-24294 to bypass NTLM authentication protections through local reflection or relay attacks.
Detects instances where privileged system processes such as lsass.exe or svchost.exe attempt a network connection to the local loopback address on ports other than standard SMB ports (445, 139). This pattern is indicative of potential coercion or relay attacks, specifically targeting the authentication mechanisms of these services to an attacker-controlled SMB server.
Detects NTLM-authenticated network logons (Logon Type 3) originating from loopback IP addresses (127.0.0.1, ::1, or 0.0.0.0). This behavior is often associated with NTLM relay attacks or credential reflection bypass techniques where an adversary forces a local service to authenticate to itself to gain unauthorized access.
