MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF was identified as malicious by ClamAV and exhibits characteristics of a phishing lure, including being image-heavy with a clickable action. It contains multiple embedded URLs, some of which are marked as unknown and could lead to malicious content or further stages of an attack. No scripts were extracted, but the PDF structure itself suggests an attempt to trick the user into navigating to an external resource.
