MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is identified as malicious by ClamAV with a signature indicating it is a phishing trojan. It contains an embedded URI pointing to a Google feedproxy URL, which is likely used as a lure. Although the document body is heavily obfuscated and unreadable, the presence of a PDF URI and the ClamAV detection strongly suggest a phishing attempt.
