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

The PDF contains a large number of embedded links to external websites, a technique commonly used for SEO poisoning or phishing. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports a phishing or malicious redirection intent. The document body, though heavily obfuscated, contains references to 'Free portfolio blogger template' which may be a lure to disguise the malicious nature of the links.
