T1059.005 Visual Basic
T1566.001 Spearphishing Attachment
This XLS file contains VBA macros, including an AutoOpen function, which is a common technique for executing malicious code upon opening. The presence of CreateObject calls suggests the macro is capable of launching external processes or manipulating the system. While the specific payload is not directly visible, the overall pattern indicates a macro-based downloader designed to execute a second-stage payload, likely via PowerShell.
Heuristics 6
-
AutoOpen macro high OLE_VBA_AUTOOPENAutoOpen 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.
-
VBA macros detected medium OLE_VBA_MACROSDocument contains VBA macro code
-
Environ() call (env variable access) low OLE_VBA_ENVIRONEnviron() call (env variable access)
-
Macro capabilities present but unconfirmed info MACRO_CAPABILITY_UNCORROBORATEDThe document's VBA exposes execution capabilities (Shell/WScript/CreateObject/auto-exec) but nothing corroborates malicious intent — no obfuscation, memory-exec primitive, download+exec chain, encoded payload, LOLBin, DDE, AV hit, or suspicious URL. The verdict was capped at 'suspicious' so legitimate macro-heavy business documents are not flagged malicious on capability presence alone.
