T1566.001 Spearphishing Attachment

The PDF file is identified as malicious by multiple heuristics, including a machine learning classifier and ClamAV, flagging it as a phishing trojan. The 'PDF_IMAGE_LURE' heuristic indicates it's an image-based document designed to trick users into clicking an embedded URI. The primary malicious URL identified is https://maypoin.ru/123?utm_term=mark+12+28-31+nkjv, which is likely the destination for the phishing attempt.
