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

The PDF file contains a large number of external links, many of which point to other PDFs, indicating a link farm for SEO purposes. One of the embedded URLs, http://siteslocate.com/ferraro/hypoglycemic/politely.ZG93bmxvYWR8RnkxTVRGaU5YeDhNVFkxTnpBek5qSXlNM3g4TWpVM05IeDhLRTBwSUhKbFlXUXRZbXh2WnlCYlJtRnpkQ0JIUlU1ZA?interests=RmlmYSAyMgRml&slump=prononounced&, is likely a lure to download a second-stage payload. The PDF structure and numerous links suggest a malicious campaign focused on distributing further malware.
