MSBuild Suspicious Spawned By Script Process: endpointEndpointrisk_score:492024-09-30version:3
The following analytic detects the suspicious spawning of MSBuild.exe by Windows Script Host processes (cscript.exe or wscript.exe). This behavior is often associated with malware or adversaries executing malicious MSBuild processes via scripts on compromised hosts. The detection leverages Endpoint Detection and Response (EDR) telemetry, focusing on process creation events where MSBuild is a child of script hosts. This activity is significant as it may indicate an attempt to execute malicious code. If confirmed malicious, it could lead to unauthorized code execution, potentially compromising the host and allowing further malicious activities.
Suspicious MSBuild Rename: endpointEndpointrisk_score:632024-10-17version:6
The following analytic detects the execution of renamed instances of msbuild.exe. It leverages data from Endpoint Detection and Response (EDR) agents, focusing on process names and original file names within the Endpoint data model. This activity is significant because msbuild.exe is a legitimate tool often abused by attackers to execute malicious code while evading detection. If confirmed malicious, this behavior could allow an attacker to execute arbitrary code, potentially leading to system compromise, data exfiltration, or further lateral movement within the network.
Suspicious MSBuild Spawn: endpointEndpointrisk_score:422024-09-30version:4
The following analytic identifies instances where wmiprvse.exe spawns msbuild.exe, which is unusual and indicative of potential misuse of a COM object. This detection leverages data from Endpoint Detection and Response (EDR) agents, focusing on process relationships and command-line executions. This activity is significant because msbuild.exe is typically spawned by devenv.exe during legitimate Visual Studio use, not by wmiprvse.exe. If confirmed malicious, this behavior could indicate an attacker executing arbitrary code or scripts, potentially leading to system compromise or further malicious activities.
Suspicious msbuild path: endpointEndpointrisk_score:492024-09-30version:5
The following analytic detects the execution of msbuild.exe from a non-standard path. It leverages data from Endpoint Detection and Response (EDR) agents, focusing on process execution logs that deviate from typical msbuild.exe locations. This activity is significant because msbuild.exe is commonly abused by attackers to execute malicious code, and running it from an unusual path can indicate an attempt to evade detection. If confirmed malicious, this behavior could allow an attacker to execute arbitrary code, potentially leading to system compromise and further malicious activities.
