Windows Process Injection into Commonly Abused Processes: endpointEndpointNoneversion:9
The following analytic detects potential process injection attempts into executables that are commonly abused leveraging Sysmon EventCode 10.
It identifies Access Mask requests (0x40 and 0x1fffff) to processes such as notepad.exe, wordpad.exe and calc.exe, excluding common system paths like System32, Syswow64, and Program Files.
This activity was associated with the SliverC2 framework by BishopFox.
Monitoring this activity may indicate an initial payload attempting to execute malicious code.
Windows Java Spawning Shells: endpointEndpoint2025-10-25version:12
The following analytic identifies instances where java.exe or w3wp.exe spawns a Windows shell, such as cmd.exe or powershell.exe. This detection leverages data from Endpoint Detection and Response (EDR) agents, focusing on process and parent process relationships. This activity is significant as it may indicate exploitation attempts, such as those related to CVE-2021-44228 (Log4Shell). If confirmed malicious, attackers could execute arbitrary commands, potentially leading to system compromise, data exfiltration, or further lateral movement within the network.
Web or Application Server Spawning a Shell: endpointEndpointNoneversion:5
The following analytic detects instances where Java, or Tomcat
processes spawn a Linux shell, which may indicate exploitation attempts, such as
those related to CVE-2021-44228 (Log4Shell). This detection leverages Endpoint Detection
and Response (EDR) telemetry, focusing on process names and parent-child process
relationships. This activity is significant as it can signify a compromised Java
application, potentially leading to unauthorized shell access. If confirmed malicious,
attackers could execute arbitrary commands, escalate privileges, or maintain persistent
access, posing a severe threat to the environment.
SAP NetWeaver Visual Composer Exploitation Attempt: networkWeb ServerNoneversion:5
Detects potential exploitation attempts targeting CVE-2025-31324, a critical unauthenticated file upload vulnerability in SAP NetWeaver Visual Composer.
This flaw allows remote attackers to send specially crafted POST requests to the /developmentserver/metadatauploader endpoint, enabling arbitrary file uploads—commonly webshells—resulting in full system compromise.
The detection looks for HTTP HEAD or POST requests with a 200 OK status to sensitive Visual Composer endpoints, which may indicate reconnaissance or active exploitation.
Successful exploitation can lead to attackers gaining privileged access, deploying malware, and impacting business-critical SAP resources.
Immediate patching and investigation of suspicious activity are strongly recommended, as this vulnerability is being actively exploited in the wild.
Java Writing JSP File: endpointEndpointNoneversion:13
The following analytic detects the Java process writing a .jsp file to disk, which may indicate a web shell being deployed. It leverages data from the Endpoint datamodel, specifically monitoring process and filesystem activities. This activity is significant because web shells can provide attackers with remote control over the compromised server, leading to further exploitation. If confirmed malicious, this could allow unauthorized access, data exfiltration, or further compromise of the affected system, posing a severe security risk.
