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.

Heuristics 4

  • Workbook_Open macro high OLE_VBA_WBOPEN
    Workbook_Open macro
  • Suspicious extracted artifact high EXTRACTED_FILE_STATIC_TRIAGE
    One or more files extracted from inside this sample matched static suspicious-content checks such as script obfuscation, encoded payload blobs, packed data, or execution/download terms.
  • VBA macros detected medium OLE_VBA_MACROS
    Document contains VBA macro code
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
