MITRE ATT&CK

T1059.005 Visual Basic T1204.002 Malicious File

The sample is a Microsoft Word template file containing VBA macros. Heuristics indicate the exploitation of CVE-2012-0158, a known vulnerability in MSCOMCTL.ListView. The presence of AutoOpen and Auto_Close macros, along with CreateObject calls and obfuscated strings, suggests the macros are designed to execute malicious code upon opening the document. The primary intent appears to be exploiting the CVE-2012-0158 vulnerability to gain initial access.

Heuristics 7

MSCOMCTL.ListView — CVE-2012-0158 high CVE likely CVE_2012_0158

MSCOMCTL.ListView — CVE-2012-0158
AutoOpen macro high OLE_VBA_AUTOOPEN

AutoOpen macro
Auto_Close macro high OLE_VBA_AUTOCLOSE

Auto_Close macro
CreateObject call high OLE_VBA_CREATEOBJ

CreateObject call
VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXEC

Compiled 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.
Suspicious extracted artifact high EXTRACTED_FILE_STATIC_TRIAGE

One 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.
VBA macros detected medium OLE_VBA_MACROS

Document contains VBA macro code
