MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF file contains an embedded URI pointing to a suspicious domain, identified by heuristics and a machine learning classifier as malicious. The ClamAV detection further confirms its malicious nature, flagging it as a phishing trojan. The document body, though heavily obfuscated, includes a URL that likely serves as the primary lure for the attack.
