MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The file is a PDF document that contains embedded URLs, one of which is flagged as potentially malicious. The ClamAV detection indicates it is a phishing trojan. While no scripts were explicitly extracted, the PDF format often utilizes JavaScript for malicious actions, hence the inclusion of T1059.007. The document body's content suggests a lure to disguise the malicious intent.
