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

The PDF file contains a large number of external links, identified as a link farm. The ClamAV detection as 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports a phishing or malicious download intent. The embedded document body text also contains multiple URLs, reinforcing the link farm attack pattern. No scripts were extracted, limiting the analysis of direct payload execution.
