MITRE ATT&CK

T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The sample is a malicious PowerPoint document containing an embedded OLE object. This object, identified as a potential CVE-2026-21514 exploitation shape, likely contains a malicious executable or link. The embedded URL http://get-adobereader.com/thyr.exe suggests the document's intent is to lure the user into downloading and executing a secondary payload, masquerading as legitimate software.

Heuristics 5

Ole10Native package carries executable/script file type high OFFICE_PACKAGE_RISKY_FILE

OLE Package displayName or fullPath ends in an executable or script-capable extension. Even without UI extension spoofing, embedding a runnable payload inside an Office document is a high-risk delivery pattern.
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.
Embedded OLE object medium OOXML_OLE_OBJECT

Document contains an embedded OLE object
Payload URL recovered from embedded OLE object (1 URL) info OOXML_EMBEDDED_OBJECT_URL

An embedded OLE object (xl/word/ppt embeddings) carries a next-stage download URL in its Ole10Native/Package stream — stored literally (incl. UTF-16) or base64-encoded — which the package-level URL sweep does not see. Surfaced as an IOC; self-validating (only real payload hosts).
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.
