T1566.001 Spearphishing Attachment

This PDF document is identified as malicious by ClamAV and an ML classifier. It employs an image-only lure, typical of phishing, with a clickable link embedded. The heuristic 'PDF_IMAGE_LURE' indicates the document is designed to trick users into interacting with a malicious URL, which is present in the extracted URLs and heuristics. No scripts were extracted, but the PDF structure itself suggests a phishing attempt.
