MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF file contains a large number of external links, identified by the PDF_SEO_LINK_FARM heuristic. The document body also contains a prominent URL, 'http://fivestarsafaris.com/uploads/1/3/0/4/130436145/130436145.html#les+miserables+full+movie+online+fre', which appears to be a lure. The primary purpose seems to be to redirect users to a network of other PDF files hosted on various domains, likely for SEO spam or to distribute further malicious content.

Heuristics 3

  • Embedded URL info EMBEDDED_URL
