MITRE ATT&CK
T1059.001 PowerShell T1204.002 Malicious File T1566.001 Spearphishing Attachment

The file is a malicious Word document containing VBA macros. The document body explicitly instructs the user to 'Enable Content', a common lure to bypass security measures. Heuristics indicate the presence of a Document_Open macro that references PowerShell, suggesting it's designed to download and execute a second-stage payload. The ClamAV detection further confirms its malicious nature.

Heuristics 11

  • PowerShell reference in VBA critical OLE_VBA_PS
    PowerShell reference in VBA
  • ClamAV: Win.Trojan.PowerShell-6312116-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.PowerShell-6312116-0
  • Reference to PowerShell high SC_STR_POWERSHELL
    Reference to PowerShell
  • Document_Open macro high OLE_VBA_DOCOPEN
    Document_Open macro
  • GetObject call high OLE_VBA_GETOBJ
    GetObject call
  • 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.
  • Visible LOLBin command execution instruction high SE_LOLBIN_RUN_COMMAND
    Document contains instructions or visible command text involving Windows script/execution tools such as PowerShell, mshta, cmd, rundll32, or regsvr32
  • 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
  • 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.
