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

The PDF file contains a large number of external links, many of which appear to be part of an SEO link farm. The heuristic 'PDF_SEO_LINK_FARM' indicates a mass of external PDF links, and the presence of URLs like 'http://bestentrypoint.com/carotidynia/' suggests a malicious intent to redirect users to potentially harmful content. No scripts were extracted from this sample.
