T1566.001 Spearphishing Attachment

The PDF is identified as malicious by ClamAV and an ML classifier, and it exhibits characteristics of a phishing lure. The heuristic 'PDF_IMAGE_LURE' indicates it's an image-only document with a clickable action, designed to trick users into clicking an external URI. The embedded URL points to a suspicious domain, likely serving as a landing page for further malicious activity.
