T1566.001 Spearphishing Attachment
T1203 Exploitation for Client Execution
T1027 Obfuscated Files or Information
The RTF document contains a high amount of hex-encoded data within an OLE object, which is flagged as suspicious. This data contains a PE header, indicating it is likely a packed or obfuscated executable payload. The presence of OLE object and embedded data heuristics strongly suggests an attempt to deliver a secondary malicious file.
Heuristics 6
-
PE header (with DOS stub) in hex data critical RTF_MZ_HEXHex-encoded PE (MZ + DOS stub) found inside RTF — likely an embedded executable payload
-
Package object class high RTF_OBJCLASS_PACKAGEOLE Package object — can wrap arbitrary files
-
Large hex data blocks in OLE object high RTF_EXCESSIVE_HEXRTF contains ~2651KB of hex-encoded data inside \objdata sections — may hide a payload
-
OLE object data medium RTF_OBJDATARTF contains 1 \objdata section(s) — embedded OLE objects
-
Embedded OLE object medium RTF_OBJEMBRTF contains \objemb — embedded OLE object
-
Suspicious extracted artifact info EXTRACTED_FILE_STATIC_TRIAGEOne 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.
