MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF contains a large number of external links, a technique commonly used for SEO poisoning or phishing campaigns. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports a phishing or traffic redirection intent. No scripts were extracted, and the document body was heavily obfuscated, limiting further analysis of the specific lure.
