MITRE ATT&CK

T1566.002 Spearphishing with Other Weapons T1059.005 Visual Basic T1059.001 PowerShell

The sample is a malicious Office document containing VBA macros. The Workbook_Open macro is designed to execute automatically upon opening the document. It manipulates sheet visibility and interacts with shapes, suggesting an attempt to present a specific user interface or trigger further malicious activity. The presence of 'CreateObject' and references to 'wscript' indicate potential for executing external scripts or commands, though no direct download or execution URLs were found in the provided script. The macro's complexity and auto-execution nature point towards a downloader or initial access mechanism.

Heuristics 7

Reference to Windows Script Host high SC_STR_WSCRIPT

Reference to Windows Script Host
Workbook_Open macro high OLE_VBA_WBOPEN

Workbook_Open macro
CreateObject call high OLE_VBA_CREATEOBJ

CreateObject call
VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXEC

Compiled VBA/cache stream contains an auto-execution token together with shell/download/object-execution tokens. This catches p-code-only or source-extraction-failure macro documents where visible source is unavailable.
Suspicious extracted artifact high EXTRACTED_FILE_STATIC_TRIAGE

One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
VBA macros detected medium OLE_VBA_MACROS

Document contains VBA macro code
Environ() call (env variable access) low OLE_VBA_ENVIRON

Environ() call (env variable access)
