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

The PDF file contains a large number of embedded links to external PDF files, a technique often used for SEO manipulation or to redirect users to malicious sites. The document body and heuristic firings indicate a clear advance-fee scam lure, aiming to trick users into believing they have won a prize or are eligible for a large sum of money, requiring them to follow links to claim it. The ClamAV detection further supports the malicious nature of the file.

Heuristics 4
