MITRE ATT&CK
T1566.002 Spearphishing Attachment T1059.001 PowerShell T1204.002 Malicious Link

The PDF contains a large number of external links, with one heuristic specifically identifying it as a 'PDF_SEO_LINK_FARM'. The primary malicious URL identified is http://mydrugdir.com/ZG93bmxvYWR8SmgzWWpWdWNYeDhNVFkxTnpFNE5qazFOWHg4TWpVM05IeDhLRTBwSUhKbFlXUXRZbXh2WnlCYlJtRnpkQ0JIUlU1ZA.cornelius.granola.faxitnice/c29uaWNyaWRlcnNzYXZlZmlsZXBjZG93bmxvYWQc29/musicologists/revile/packaged/, which likely serves as a distribution point for malware. No scripts were extracted, but the sheer volume of links suggests a campaign to drive traffic to malicious sites.
