MITRE ATT&CK
T1559.001 Component Object Model Hijacking
T1204.002 Malicious File
The RTF file contains embedded OLE object data, specifically a package object, which is a strong indicator of malicious intent. ClamAV signatures confirm this, identifying the file as Win.Trojan.Clicker-4220. The presence of a PE header within the hex data further suggests an embedded executable. The primary attack pattern involves leveraging OLE object embedding to deliver a malicious payload.
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.Clicker-4220 critical CLAMAV_DETECTIONClamAV detected this file as malware: Win.Trojan.Clicker-4220
-
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
