MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains an embedded JavaScript stream and is flagged as an image-only document with an action trigger, typical of a phishing lure. The heuristic 'PDF_IMAGE_LURE' indicates a full-page screenshot hiding a clickable button that launches or submits to an attacker URL. The embedded URL 'https://pixomot.ru/uplcv?utm_term=deductive+and+inductive+method+of+teaching+pdf' is the most prominent IOC, likely serving as the destination for the user's click.
