T1204.002 Malicious File
The file contains VBA macros, specifically an Auto_Close function, which is designed to execute arbitrary commands. Critical heuristics indicate the use of Shell() and a character-shift decoding mechanism to obscure the command. This strongly suggests the macro's purpose is to download and execute a second-stage payload. No specific family could be identified, and the only extracted URL was benign.
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@j.mp/chobesjjjj
