MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF contains a large number of embedded links to external PDF files, a technique commonly used for SEO poisoning or phishing campaigns. The ClamAV detection of 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports a phishing or malicious redirection intent. The document body text, though partially corrupted, contains phrases like 'Sample of affidavit of loss passport philippines' which could be used as a lure.
