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

The PDF file contains a large number of embedded external links, as indicated by the PDF_SEO_LINK_FARM heuristic. The primary URL, http://partymoscato.com/uploads/1/3/0/7/130776405/130776405.html#stones+of+barenziah+in+skyrim, suggests a lure related to the game Skyrim, possibly to disguise malicious activity. The extensive link farm points towards an attempt to manipulate search engine results or redirect users to potentially harmful content hosted on various domains.
