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

The PDF document contains heuristics indicating it's a fake invoice or payment lure, and impersonates a cloud document sharing service like Dropbox. The embedded URL, https://moviess.mypen.is/DROPBOX/Final-Payment/, is likely the next stage of the attack, designed to trick the user into downloading a malicious payload or providing credentials.
