MITRE ATT&CK
T1059.005 Visual Basic T1204.002 Malicious File T1105 Ingress Tool Transfer

The Workbook_Open VBA macro contains a call to URLDownloadToFileA, which is used to download a file from the embedded URL http://sparepartiran.com/js/s0/11056.jpg. The downloaded file is saved to C:\Users\Public\Documents\bxcyannjodzkmzvjbeqresjffflcoxbuyhrzmbgwdcdn, likely to be executed as a second-stage payload. The use of Shell() and URLDownloadToFileA indicates a malicious intent to download and run external code.
