MITRE ATT&CK
T1566.001 Spearphishing Attachment

The sample is a malicious OOXML document containing an embedded OLE object. This object is identified as a risky file that drops an auto-executable payload named 'FlashPresentation.scr'. ClamAV signatures confirm this as Win.Trojan.Remotemanipulator-9849652-0. The document body attempts to trick the user into interacting with the embedded object by posing as a technical specification for website development.

Heuristics 5

  • ClamAV: Win.Trojan.Remotemanipulator-9849652-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Win.Trojan.Remotemanipulator-9849652-0
  • Ole10Native package drops an auto-executable payload critical OFFICE_PACKAGE_RISKY_FILE
    OLE Package displayName or fullPath ends in a directly auto-executable extension (a runnable binary or a script the default shell host runs on double-click). Embedding such a payload inside an Office document has no benign authoring use — it is a malware-delivery dropper.
  • Embedded OLE object medium OOXML_OLE_OBJECT
    Document contains an embedded OLE object
  • Suspicious extracted artifact info 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.
  • 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.
