This query detects network communication to known Command and Control (C2) IP addresses used by the Medusa ransomware group, often via malicious SimpleHelp RMM servers.
This rule detects an attempted exploitation of an insecure deserialization vulnerability (CVE-2025-10035) in Fortra GoAnywhere MFT. Specifically, it looks for HTTP POST requests to the '/goanywhere/lic/accept/' URI containing the string 'bundle=' in the request body, which is indicative of an attempt to trigger the vulnerability.
Detects suspicious command execution by child processes of the GoAnywhere Managed File Transfer (MFT) application, which may indicate exploitation such as CVE-2025-10035. This behavior is indicative of post-exploitation activity related to CVE-2025-10035, as observed in campaigns by the threat actor Storm-1175.
Detects suspicious command-line activity spawned by the GoAnywhere MFT Tomcat service. This behavior is indicative of post-exploitation techniques observed following the exploitation of CVE-2025-10035, as detailed by Microsoft Threat Intelligence. The detection looks for specific discovery and execution commands launched via cmd.exe or powershell.exe from the GoAnywhere parent process.
Detects suspicious child processes spawned by the GoAnywhere MFT Tomcat service. This behavior is consistent with post-exploitation activity following a successful remote code execution exploit of CVE-2025-10035, as observed in campaigns by the threat actor Storm-1175.
Detects attempts to bypass authentication in Fortra GoAnywhere MFT by exploiting a vulnerability (CVE-2025-10035). This is achieved by sending a crafted GET request to the Unlicensed.xhtml endpoint to trigger an exception and obtain a valid license request token, which is a prerequisite for further exploitation.
