Malware Insights
The sample is a Microsoft Office document containing VBA macros, specifically a Document_Open macro, which is a common technique for initial execution. The document body presents information about the Hazel Park Educational Foundation, likely as a lure to encourage users to enable macros. The presence of a Document_Open macro suggests an attempt to automatically execute malicious code upon opening the document. The ClamAV detection as 'Doc.Trojan.Myna-1' further confirms its malicious nature. No specific malware family could be identified, but the overall pattern suggests a macro-based downloader.
