MITRE ATT&CK

T1059.005 Visual Basic T1204.002 Malicious File

The sample is a malicious OLE document containing VBA macros. The Auto_Close macro is configured to execute arbitrary code via Shell, and the extracted 'macros.bas' file shows obfuscation techniques. This suggests the document's primary purpose is to download and execute a second-stage payload, likely leveraging the Auto_Close macro for execution.

Heuristics 7

Heap-spray pattern detected high SC_HEAP_SPRAY

Repeated 0x41 (A) bytes found
Reference to Windows Script Host high SC_STR_WSCRIPT

Reference to Windows Script Host
Auto_Close macro high OLE_VBA_AUTOCLOSE

Auto_Close macro
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
Embedded URL info EMBEDDED_URL

One 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.
