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

The PDF contains a large number of external links to other PDF files, a technique often used for SEO poisoning or to distribute malicious content. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports a phishing or traffic redirection motive. The document body, though containing garbled text, mentions 'Descargar manga de akame ga kill pdf mega', suggesting a lure to download content related to popular media to mask the malicious intent.
