MITRE ATT&CK
T1059.005 Visual Basic
T1566.001 Spearphishing Attachment
The sample is an Excel document containing a Workbook_Open VBA macro, which is a common technique for initial execution. The macro source is obfuscated, and the document body presents a series of questions about patient care, likely to trick the user into enabling macros. The presence of embedded URLs suggests a potential download or redirection to malicious content. The macro's obfuscation and the Workbook_Open trigger indicate an attempt to download and execute a second-stage payload.
