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

The PDF file contains a lure instructing the user to enable macros or editing, a common technique for malware droppers. It also features a large number of embedded external PDF links, with the first being http://superiorautomi.com/uploads/1/3/0/2/130287894/3732615.pdf. This indicates a phishing or SEO poisoning attack aimed at distributing further malicious content.
