MITRE ATT&CK
T1059.005 Visual Basic
T1204.002 Malicious File
The file contains VBA macros, specifically a Workbook_Open macro, which is a common technique for executing malicious code upon opening the document. The heuristic SC_STR_URLDOWNLOAD indicates the use of an API to download content from a URL. The embedded URLs are likely used to fetch and execute a second-stage payload. The ClamAV detection further supports its malicious nature.
