The file is identified as malicious by ClamAV with the signature 'Doc.Trojan.Story-1'. Static triage indicates VBA Chr string obfuscation within the macros. The presence of a 'Document_Open' macro suggests an attempt to automatically execute malicious code upon opening the document. The document body, presented as religious text, is likely a lure to trick the user into enabling macros.
