Description

The following analytic detects the use of msiexec.exe with an HTTP or HTTPS URL in the command line, indicating a remote file download attempt. This detection leverages data from Endpoint Detection and Response (EDR) agents, focusing on process execution logs that include command-line details. This activity is significant as it may indicate an attempt to download and execute potentially malicious software from a remote server. If confirmed malicious, this could lead to unauthorized code execution, system compromise, or further malware deployment within the network.
