MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF is identified as an image-only lure, typical of phishing campaigns, designed to trick users into clicking an embedded link. The heuristic 'PDF_IMAGE_LURE' indicates a screenshot-like appearance with a clickable action. The embedded URL 'http://uasaccess.com/milli/' is the primary indicator of compromise, likely leading to a malicious site.
