MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The file is a PDF that contains a URI pointing to a suspicious domain, identified as malicious by ClamAV and a machine learning classifier. The document body, though heavily obfuscated, contains text related to 'Super Mario Run Mod 2020', suggesting a phishing or social engineering lure to drive traffic to the malicious URL. No scripts were extracted, but the presence of an external URI and the overall detection profile strongly indicate a phishing attempt.
