MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious File

The heuristic 'SE_ADVANCE_FEE_SCAM_LURE' strongly indicates the document's purpose is to deceive the user with a fake prize or funds. The presence of multiple external URIs, including one explicitly identified as 'PDF_URI', suggests a delivery mechanism for further malicious content or redirection. The ClamAV detection further confirms its malicious nature.
