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

The PDF file contains a mass of external links to other PDF documents hosted on various domains, as indicated by the PDF_SEO_LINK_FARM heuristic. The ClamAV detection of 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports a phishing or malicious redirection intent. The document body appears to be corrupted or contains obfuscated text related to a 'Premier league fixture list', likely a lure.
