MITRE ATT&CK
T1059.005 Visual Basic
T1566.001 Spearphishing Attachment
The sample is an Excel file containing Excel 4.0 (XLM) macros, specifically an Auto_Open macro, which is a known technique for executing malicious code upon opening. The document body contains obfuscated strings that appear to be URLs pointing to second-stage payloads. The XLM macros likely download and execute these payloads, indicated by the presence of strings like 'downloadFile' and 'runDll'.
Heuristics 4
