MITRE ATT&CK
T1566.001 Spearphishing Attachment

The sample is a PDF file identified as a phishing lure by heuristics, containing a single image and a clickable link. The embedded URL, while currently benign, is likely intended to redirect the user to a malicious site for credential harvesting or further malware delivery. No scripts were extracted, but the overall structure strongly suggests a phishing attack.
