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

The PDF file contains a large number of embedded links pointing to external websites, a technique commonly used for SEO poisoning or phishing. The ClamAV heuristic also flags this as a phishing-related threat. The document body, while containing garbled text, includes a title that suggests a lure. No scripts were extracted from this sample.
