MITRE ATT&CK
T1059.001 PowerShell T1204.002 Malicious File

The sample contains embedded URLs that are likely used to download and execute a second-stage payload. The heuristic 'OLE_VBA_PCODE_AUTOEXEC_EXEC' indicates that VBA code within the document is configured to execute automatically upon opening, likely initiating the download process. No specific malware family could be identified.

Heuristics 4

  • Reference to Windows Script Host high SC_STR_WSCRIPT
    Reference to Windows Script Host
  • VBA p-code auto-exec with execution tokens high OLE_VBA_PCODE_AUTOEXEC_EXEC
    Compiled VBA/cache stream contains an auto-execution token together with shell/download/object-execution tokens. This catches p-code-only or source-extraction-failure macro documents where visible source is unavailable.
  • Unsupported Office format for VBA extraction info OFFICE_FORMAT_UNSUPPORTED
    olevba could not extract VBA macros (AssertionError); format-agnostic byte-level scans still ran. Likely legacy, encrypted, or malformed OLE/OOXML — re-scanning the same bytes will yield the same outcome.
  • 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.
