T1566.001 Spearphishing Attachment
T1204.002 Malicious File
T1105 Ingress Tool Transfer
The RTF file contains embedded OLE objects, including a PE executable identified by ClamAV as Win.Trojan.Dropper-11394. This indicates the file is designed to drop and execute a secondary payload. The document body text, while seemingly innocuous, is likely a lure to entice the user to open the malicious attachment.
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
-
ClamAV: Win.Trojan.Dropper-11394 critical CLAMAV_DETECTIONClamAV detected this file as malware: Win.Trojan.Dropper-11394
-
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
