MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is identified as a PDF containing an embedded URI that points to a URL disguised as a movie download link. ClamAV detection further supports its malicious nature, classifying it as a phishing trojan. While no scripts were directly extracted, the presence of an external URI within a PDF commonly indicates an attempt to redirect the user to a malicious site, likely for credential harvesting or further malware delivery.
