MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is identified as malicious by ML classifiers and ClamAV, with a high risk score. It contains an embedded URI pointing to 'traffset.ru', which is likely part of a phishing or malware distribution scheme. The document body, though heavily obfuscated, suggests a lure related to a 'dedicated server guide'. No scripts were extracted, but the presence of an external URI and the malicious verdict strongly indicate a malicious intent.
