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

The PDF file contains a large number of external links, identified as a PDF link farm. These links point to various PDF files hosted on different domains, suggesting a tactic to manipulate search engine results or distribute further malicious content. The primary URL identified is http://adsl-63-204-18-59.benefitplans.org/uploads/1/3/1/1/131164398/131164398.html#midsummer+night%27s+dream+national+theatre+cast, which itself appears to be part of this distribution network.
