MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF file is identified as a malicious dropper by ClamAV. It employs a common image-only lure technique, presenting a screenshot to the user while hiding a clickable action that redirects to external URLs. The embedded URLs, specifically http://xincubetrade.16mb.com and http://postmasterservices01254786.ml/PDF-DOCUMENTS.html, are likely part of the attack chain, potentially serving as landing pages for phishing or delivering further malicious content.
