MITRE ATT&CK
T1059.005 Visual Basic

The sample exhibits legacy WordBasic macro virus markers, specifically 'RSN MACRO VIRUS', and is detected by ClamAV as Win.Trojan.Swlabs-2. The document body contains references to 'AutoOpen' and 'AUTOOPEN', suggesting the execution of a macro upon opening the document. This macro likely attempts to download and execute a secondary payload, consistent with a trojan downloader.

    OLE Word document contains legacy WordBasic auto-execution macro markers such as AutoOpen plus ToolsMacro/MacroFile/fileMacro/globMacro or named historical macro-virus strings.
