The sample is a PowerPoint file containing VBA macros. Critical heuristics indicate the use of Shell() and character-shift decoding to execute commands. The Auto_Close macro is present, suggesting execution upon closing the document. The embedded URL, though marked as benign, was likely intended as a download source for a secondary payload. The VBA code uses character manipulation functions like Mid, Asc, and Chr to obfuscate the Shell command.
Heuristics 6
-
Shell() call in VBA critical OLE_VBA_SHELLShell() call in VBA
-
VBA character-shift decoded Shell command critical OLE_VBA_ASC_CHR_SHIFT_SHELLVBA auto-exec macro stores an encoded command string, decodes it with a Mid/Asc/Chr character-shift loop, and passes the recovered text to Shell. This is a high-confidence command stager.
-
Auto_Close macro high OLE_VBA_AUTOCLOSEAuto_Close 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.
-
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://1230948%1230948%1230948%1230948@j.mp/vdjagsdjajfdjasgdjasgd
