MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF is identified as a phishing lure due to its image-only nature and the presence of an external URI. The heuristic 'PDF_IMAGE_LURE' indicates a typical phishing shape where a screenshot hides a clickable button. The embedded URL 'https://gimoguvi.ru/award?keyword=wedding+budget+planner+pdf' is likely the destination for this lure, aiming to trick the user into downloading further malicious content or providing sensitive information.
