T1566.001 Spearphishing Attachment
The RTF document exhibits characteristics of a dropper, with a significant portion of its file size comprising appended executable payload bytes. The OLE slack anomaly further indicates potential obfuscation or packing of malicious content within the file structure. No specific family could be identified, but the pattern suggests a malicious attachment designed to deliver a secondary payload.
Heuristics 2
-
OLE document has large unaccounted-for region high OLE_SLACK_ANOMALYOLE file is 187,136 bytes but its declared streams total only 12,338 bytes — 174,798 bytes (93%) live in unallocated sector slack. This is the canonical hiding place for pre-macro-era Office exploit payloads (XOR-encoded shellcode reached via a parser pointer-corruption bug in the document structure).
-
OLE file has appended executable-looking payload bytes high OLE_APPENDED_PAYLOADOLE compound file contains a large high-entropy region beyond the declared major streams and that region includes shellcode, PE, or loader API markers. This is a payload-carrier signal, not a specific CVE attribution by itself.
