T1059.001 PowerShell
The file is an OLE document with a large slack space and an appended executable payload, indicating it's likely a dropper. No VBA macros were extractable due to an unsupported format, but the appended payload suggests the file's primary purpose is to deliver and execute a secondary stage. The document body is a benign-looking training invitation, serving as a lure.
Heuristics 3
-
OLE document has large unaccounted-for region high OLE_SLACK_ANOMALYOLE file is 815,104 bytes but its declared streams total only 305,839 bytes — 509,265 bytes (62%) 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.
-
Unsupported Office format for VBA extraction info OFFICE_FORMAT_UNSUPPORTEDolevba could not extract VBA macros (PermissionError); format-agnostic byte-level scans still ran. Likely legacy, encrypted, or malformed OLE/OOXML — re-scanning the same bytes will yield the same outcome.
