MITRE ATT&CK

The PDF contains a large number of embedded links pointing to other PDF files, a technique often used for SEO manipulation or to host malicious content. Heuristics indicate this is a classic advance-fee fraud document shape and also a lure for MFA or one-time-code harvesting. The ClamAV detection further supports its malicious nature.
