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

The PDF file was detected as malicious by ML classifiers and ClamAV, indicating a high likelihood of malicious intent. An external URI pointing to 'trafffi.ru' was extracted, suggesting the document is designed to redirect users to a potentially harmful website. The document body, though partially corrupted, contains text related to a movie title, which serves as a lure. No scripts were extracted, but the presence of an external URI and the overall malicious verdict strongly suggest a phishing or malware distribution attempt.
