MITRE ATT&CK

T1059.001 PowerShell T1204.002 Malicious Link

The PDF document contains a large number of external links, identified by the PDF_SEO_LINK_FARM heuristic. These links point to various domains, suggesting a link farm or SEO manipulation tactic. The primary URL embedded in the document body is http://webdisk.bardosdiamondsports.com/uploads/1/3/0/7/130739311/130775136.html, which also appears to be part of this link farm. The document body itself is heavily obfuscated and contains what appears to be a title related to Nigerian customary law, likely a lure.
