MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1203 Exploitation for Client Execution
The RTF file contains an embedded OLE object, identified as a package object, which in turn contains a PE header. ClamAV detections indicate this is Win.Trojan.Webdor-9854571-0. The document body is a lure, presenting itself as a curriculum vitae to encourage the user to interact with the malicious embedded object.
Heuristics 7
-
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.Webdor-9854571-0 critical CLAMAV_DETECTIONClamAV detected this file as malware: Win.Trojan.Webdor-9854571-0
-
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
-
Embedded URL info EMBEDDED_URLOne or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.URL http://%s/files/
