T1566.001 Spearphishing Attachment
T1204.002 Malicious File
T1027 Obfuscated Files or Information
The RTF document contains an embedded OLE object which, upon extraction, reveals a PE executable. Heuristics indicate this is a Package object containing OLE object data and a PE header in hex. ClamAV detected this as 'Win.Trojan.Agent-230724'. The embedded executable is the primary payload, likely delivered via social engineering to prompt user execution.
Heuristics 5
-
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
-
ClamAV detection on extracted artifact critical EXTRACTED_FILE_CLAMAVClamAV flagged at least one file extracted from inside this sample. Even when the wrapping document carries no AV detection of its own, a hit on the carved artifact is a strong indicator the sample is a delivery vehicle.
-
Package object class high RTF_OBJCLASS_PACKAGEOLE Package object — can wrap arbitrary files
-
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
