MITRE ATT&CK
T1059.005 Visual Basic
T1204.002 Malicious File
The sample is a malicious DOC file containing VBA macros. The presence of a Document_Open macro and calls to ShellExecute and GetObject indicate that the macro is designed to execute automatically when the document is opened. The heuristic 'EXTRACTED_FILE_STATIC_TRIAGE' with signals 'Script execution terms, VBA Chr string obfuscation' further suggests the macro is obfuscated and intended for malicious execution, likely to download and run a second-stage payload.
Heuristics 6
-
Reference to ShellExecute API high SC_STR_SHELLEXECReference to ShellExecute API
-
Document_Open macro high OLE_VBA_DOCOPENDocument_Open macro
-
GetObject call high OLE_VBA_GETOBJGetObject call
-
VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXECCompiled 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_TRIAGEOne 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_MACROSDocument contains VBA macro code
