MITRE ATT&CK
T1204.002 Malicious File

The file is identified as a PDF dropper by ClamAV. It contains embedded URLs, one of which is explicitly flagged as an external URI. The presence of a visual download button suggests a social engineering lure to trick the user into interacting with the document and potentially downloading further malicious content. The document body is heavily obfuscated and does not provide further insight into the specific lure.
