MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file is identified as a phishing lure due to its image-only nature and embedded clickable link. The ClamAV detection and the presence of multiple external URLs strongly suggest malicious intent, likely to redirect users to a phishing site or initiate a malware download. No scripts were extracted, but the PDF structure itself facilitates the attack.
