MITRE ATT&CK
T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF file contains a large number of embedded external links to other PDF documents, as indicated by the PDF_SEO_LINK_FARM heuristic. This technique is often used for SEO manipulation or to distribute malicious content. The ClamAV detection of Pdf.Phishing.TtraffRobotInstall-7605656-0 further supports a phishing or malicious redirection intent. The document body itself contains garbled text, suggesting it is not intended for direct user interaction but rather as a container for the malicious links.

Heuristics 3
