MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1204.002 Malicious File
The RTF document contains a large amount of hex-encoded data within an OLE object, flagged as suspicious by heuristics. ClamAV detected this embedded object as Win.Trojan.Lee-1. The document body suggests the user double-click to view it better, likely to trigger the execution of the embedded malicious object.
Heuristics 6
-
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
-
Large hex data blocks in OLE object high RTF_EXCESSIVE_HEXRTF contains ~1817KB 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.
