Creation Exe for Service with Unquoted Path — Sigma Rule

Sigma rule 8c3c76ca-8f8b-4b1d-aaf3-81aebcd367c9. Creation Exe for Service with Unquoted Path — Sigma Rule. Adversaries may execute their own malicious payloads by hijacking vulnerable file path references. Adversaries can take advantage of paths that lack surrounding quotations by placing an executable in a higher level directory within the path, so that Windows will choose the adversary's executable to launch.
