MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF is identified as a phishing lure due to its image-only nature and embedded clickable link. The heuristic PDF_IMAGE_LURE indicates a common phishing tactic where a screenshot is used to hide a malicious link. The embedded URL points to a suspicious domain, likely serving as the next stage of the attack. No scripts were extracted from this sample.
