MITRE ATT&CK
T1566.001 Spearphishing Attachment

This PDF document is identified as malicious by ClamAV and a machine learning classifier. It employs a common phishing tactic by presenting a full-page image, likely a screenshot, to obscure a clickable link. The heuristic 'PDF_IMAGE_LURE' indicates this is a typical shape for a phishing lure where a screenshot hides an attacker-controlled URL. The embedded URL, https://xajibur.ru/wb?keyword=finders%20keepers%20movie%20trailer, is the primary indicator of compromise.
