MITRE ATT&CK

T1059.005 Visual Basic T1566.001 Spearphishing Attachment

The file is identified as malicious by ClamAV with the signature Doc.Trojan.Thus-8. Static analysis detected VBA macros, specifically a Document_Open macro, indicating that the document is designed to execute malicious code upon opening. The document body contains text about a novel, which appears to be a lure to disguise the malicious intent. No specific IOCs were extracted, but the presence of a Document_Open macro strongly suggests an attempt to download and execute a secondary payload or perform other malicious actions.
