MITRE ATT&CK
T1059.005 Visual Basic
The sample is an Excel document containing VBA macros, indicated by the OLE_VBA_MACROS heuristic. The document body lists various business projects and investment opportunities, suggesting a lure for a business investment scam. The embedded URL http://www.qyx.baoji.goy.cn is likely part of the scam or a command and control channel. The presence of SC_HEAP_SPRAY and SC_NOP_EQUIV_SLED heuristics suggests potential exploitation or obfuscation techniques within the macros.
