MITRE ATT&CK
T1059.005 Visual Basic T1204.002 Malicious File

The file contains an Excel 4.0 macro (XLM) with an Auto_Open function, which is a known technique for executing malicious code. The macro likely uses the RUN function to download and execute a payload from the URL http://gracefullifetime.com/yqagtiljgk/D .exe. The document body also contains text that may serve as a lure to encourage macro execution.

Heuristics 4

  • XLM Auto_Open with dangerous formula APIs high OLE_XLM_DANGEROUS_FN
    Excel 4.0 macro sheet contains an Auto_Open / Auto_Close entry and dangerous XLM formula APIs that can invoke programs, write files, or transfer control without VBA.
  • Excel 4.0 (XLM) macro sheet present medium OLE_XLM_AUTOOPEN
    Workbook contains an Excel 4.0 macro sheet sub-stream — XLM is rarely seen in modern legitimate workbooks and was a major Office malware vector during 2020-2022.
  • Macro/content-enable lure medium SE_ENABLE_LURE
    Document instructs the user to enable macros or editing — a common technique used by malware droppers to bypass Office macro security settings
  • 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.
