T1059.001 PowerShell
The sample is an Excel file containing Excel 4.0 macros, indicated by the OLE_XLM_AUTOOPEN and OLE_XLM_DANGEROUS_FN heuristics. The SC_STR_SHELLEXEC firing suggests the macro attempts to execute external code. The embedded URL likely serves as the download location for a second-stage payload, as suggested by the CLAMAV_DETECTION rule. The macro's intent is to download and execute a payload, aligning with common downloader tactics.
