MITRE ATT&CK

T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

The sample is a malicious PPTX file containing an embedded OLE object. This object, identified as a package, is designed to drop an executable payload named 'siparisler.jar'. The presence of this embedded executable strongly suggests an attack pattern involving spearphishing, where the document is intended to trick the user into opening it and subsequently executing the dropped payload.

Heuristics 3

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.
