MITRE ATT&CK
T1566.002 Phishing: Spearphishing Attachment
T1059.005 Command and Scripting Interpreter: Visual Basic
The sample is an Excel 4.0 (XLM) macro-enabled workbook. It contains an Auto_Open macro, which is a common technique for executing malicious code upon opening the file. The document body displays a lure instructing the user to 'Enable Editing' to bypass security measures and view protected content. No specific download or execution URLs were found in the extracted scripts, but the presence of the Auto_Open macro and the lure strongly indicate a macro-based malware delivery attempt.
