MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is identified as malicious by ClamAV with a Pdf.Phishing.Trojan signature. It contains an embedded URI that leads to a URL promising a free iPhone, a typical lure for phishing campaigns. The document body is heavily obfuscated and appears to be generated by wkhtmltopdf, suggesting it's not a standard user-created document.
