What it detects

This rule detects msiexec.exe installing an MSI package from a user writable or remote location such as AppData, Temp, ProgramData or an HTTP URL, an execution-proxy technique used by the Handala group to run malicious installers from untrusted paths. Legitimate installers usually run from trusted staging or download folders rather than these locations. Combined with other indicators this points to attacker-driven payload deployment.
