MITRE ATT&CK
T1566.001 Spearphishing Attachment

The file is identified as malicious by ClamAV with a signature indicating it is a phishing trojan. It contains an embedded URI that, while flagged as benign, is presented in a context suggesting a lure. The document body is heavily obfuscated, preventing a clear understanding of its specific content, but the overall structure and heuristic firings point to a phishing attempt disguised as an assignment.
