T1566.001 Spearphishing Attachment

The PDF file is identified as malicious by ClamAV and an ML classifier, and exhibits characteristics of a phishing lure. The heuristic 'PDF_IMAGE_LURE' indicates it's an image-only document with a clickable action, likely to redirect the user to a malicious URL. The embedded URL 'https://dugedepap.ru/aws?utm_term=best+google+cardboard+games+2019' is a strong indicator of a phishing attempt or a download lure.
