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

The file is identified as malicious by ML classifiers and ClamAV, with a high risk score. It contains an embedded URI pointing to 'xezojetit.ru', which is likely a phishing or malware distribution domain. The document body, though heavily obfuscated, suggests a lure related to 'Bsc agriculture entrance exam model question papers'. No scripts were extracted, but the PDF structure and URI heuristic indicate a malicious intent to redirect the user.
