MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains a large number of external links, a technique commonly used for SEO spam or to redirect users to malicious sites. The document body contains the string 'Proven incest sex', which appears to be a lure. No scripts were extracted from this sample. The primary attack pattern involves directing users to a link farm.

Heuristics 3

Embedded URL info EMBEDDED_URL
