MITRE ATT&CK
T1059.005 Visual Basic
T1218 System Binary Proxy Execution
The file contains Excel 4.0 macros, specifically an Auto_Open macro that utilizes dangerous functions like RUN. This indicates an attempt to execute arbitrary commands, likely for downloading and executing a second-stage payload. The presence of an embedded URL, although currently marked as benign, is a common delivery vector for such attacks. The heuristic for visible LOLBin command execution further supports the malicious intent.
