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

The PDF file contains a large number of embedded links to external PDF files, a technique often used to create link farms for SEO or to distribute malicious content. The heuristic 'SE_ADVANCE_FEE_SCAM_LURE' strongly suggests the document's content is designed to trick users into believing they are due a prize or parcel, which is a common advance-fee fraud tactic. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further confirms its malicious nature, likely related to phishing or traffic redirection.

Heuristics 4
