MITRE ATT&CK
T1566.002 Spearphishing Attachment

The file is a PDF that contains an embedded URL pointing to another PDF. The ClamAV heuristic identifies this as a phishing attempt. The document body, though heavily obfuscated, contains references to URLs which are likely part of the lure. The primary IOC is the external URI identified by the PDF_URI heuristic.
