MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file is identified as malicious by ClamAV and an ML classifier, and it employs an image-only lure typical of phishing attacks. The heuristic 'PDF_IMAGE_LURE' indicates a clickable action that likely leads to the embedded URL, which is a common technique for delivering malicious content or phishing pages. No scripts were extracted from this sample, but the presence of external URIs suggests a redirection to a potentially harmful site.
