MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is a PDF containing an embedded URL that leads to a suspicious domain, identified as malicious by ClamAV and an ML classifier. The document body, though heavily obfuscated, contains keywords related to product listings, suggesting a phishing lure. No scripts were extracted, but the presence of an external URI and the overall detection profile strongly indicate a phishing attack.
