MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious Link

One of the embedded URLs, http://awarefinance.com/herself.isle?thuggish=sollars.mediacaster.ZG93bmxvYWR8MTl6Tm1WbmJYeDhNVFkxTmprNE1UVXdOSHg4TWpVM05IeDhLRTBwSUhKbFlXUXRZbXh2WnlCYlJtRnpkQ0JIUlU1ZA/UGhvdG9zaG9wIDIwMjIgKHZlcnNpb24gMjMpUGh, likely serves as a download redirector for malicious payloads.
