T1566.001 Spearphishing Attachment

This PDF document is identified as malicious by multiple heuristics, including a machine learning classifier and ClamAV, which specifically flagged it as Pdf.Phishing.Trojan. The PDF employs an image-only lure, a common tactic in phishing campaigns, to entice users to click on an embedded external URI. The primary IOC is the URL 'https://jottigo.ru/award?keyword=baricco+castelli+di+rabbia+pdf', which is likely used to host or redirect to malicious content.
