The file is identified as malicious by ClamAV with the signature Doc.Trojan.WhiteIce-1. Static analysis detected a VBA auto-execution macro that uses Shell execution, indicating an attempt to run arbitrary code. The document body is a seemingly legitimate notification about educational planning, likely serving as a lure. The embedded URL is suspicious due to its unusual characters and unknown reputation.

Heuristics 6

  • ClamAV: Doc.Trojan.WhiteIce-1 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Doc.Trojan.WhiteIce-1
  • Heap-spray pattern detected high SC_HEAP_SPRAY
    Repeated 0x41 (A) bytes found
  • 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.
  • 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 project contains no executable statements low OLE_VBA_MACROS
    Document contains a VBA project, but extracted modules only contain attributes/options/comments and no executable statements.
  • 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.
