The sample exhibits characteristics of a legacy macro virus, specifically identified by 'RSN MACRO VIRUS' markers and the presence of macros like 'AutoOpen' and 'Attack'. The document body contains text that appears to be part of the macro's payload, including references to its creation date and author, and potentially malicious macro names. The ClamAV detection further confirms its malicious nature.
