T1059.005 Visual Basic
T1059 Command and Scripting Interpreter
T1566.001 Spearphishing Attachment
T1203 Exploitation for Client Execution
The sample contains VBA macros, including a Document_Open macro that utilizes the Shell() function to execute arbitrary commands. The script appears to be heavily obfuscated, but the presence of the Shell() call strongly suggests it's designed to download and execute a secondary payload. The specific URL found, while benign, is likely a placeholder or part of the obfuscation.
Heuristics 5
-
VBA macros detected medium 3 related findings OLE_VBA_MACROSDocument contains VBA macro code
-
Shell() call in VBA critical OLE_VBA_SHELLShell() call in VBA
-
Document_Open macro high OLE_VBA_DOCOPENDocument_Open macro
-
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.
-
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://schemas.openxmlformats.org/drawingml/2006/main In document text (OLE body)
