MITRE ATT&CK
T1059.005 Visual Basic
T1204.002 Malicious File
The sample is a malicious Excel file containing a VBA macro that is automatically executed upon opening (Auto_Open). The script utilizes `CreateObject("WindowsInstaller.Installer")` to download and execute a payload from the URL `http://84.32.188.141/`. The macro also attempts to clean up the worksheet by deleting pictures and used cells.
Heuristics 6
-
Auto_Open macro high OLE_VBA_AUTOAuto_Open macro
-
CreateObject call high OLE_VBA_CREATEOBJCreateObject 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
-
Embedded URL info EMBEDDED_URLOne or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.URL http://84.32.188.141/
