T1059.001 PowerShell
T1204.002 Malicious File
The sample is a PowerPoint file containing a VBA Auto_Open macro. This macro is designed to execute code using the GetObject function, which is a common technique for launching malicious payloads. The presence of a large encoded blob within the VBA macros suggests obfuscation, likely to hide the execution of a second-stage payload. No specific family could be identified, but the technique is indicative of a downloader or dropper.
Heuristics 5
-
Auto_Open macro high OLE_VBA_AUTOAuto_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.
-
VBA macros detected medium OLE_VBA_MACROSDocument contains VBA macro code
-
Suspicious extracted artifact info 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.
