The VBA macro contains an Auto_Close function that uses Shell() to execute a command. This command is constructed by concatenating strings to form a URL, which is then likely used to download and execute a second-stage payload. The obfuscated nature of the command and the use of Shell() indicate malicious intent.
Heuristics 6
-
Shell() call in VBA critical OLE_VBA_SHELLShell() call in VBA
-
Obfuscated VBA Shell command with URL critical OLE_VBA_OBFUSCATED_SHELL_URLVBA macro invokes Shell with command text assembled through decoder or string-manipulation functions and includes a URL. This is a high-confidence downloader/dropper pattern, stronger than Shell or URL evidence on their own.
-
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://www.utf8-chartable.de/unicode-utf8-table.pl?start=1024&utf8=-&unicodeinhtml=dec
