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 screenshot as the document content, with an embedded URI that likely leads to a malicious site. The heuristic 'PDF_IMAGE_LURE' confirms this, indicating the document's structure is designed to trick users into interacting with a hidden link.
