T1566.001 Spearphishing Attachment
The file is a PowerPoint presentation containing a VBA macro. The Auto_Close macro, combined with a GetObject call, suggests an attempt to automatically execute code upon closing the presentation. The presence of a long encoded blob within the VBA macros indicates obfuscation, likely to conceal a downloader or other malicious functionality. The macro's execution is triggered by the Auto_Open event and the GetObject function, which are common techniques for initial execution.
Heuristics 5
-
Auto_Close macro high OLE_VBA_AUTOCLOSEAuto_Close 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.
-
VBA macros detected medium OLE_VBA_MACROSDocument contains VBA macro code
-
