MITRE ATT&CK
T1203 Exploitation for Client Execution
T1566.001 Spearphishing Attachment
The sample is an RTF document containing embedded OLE objects, flagged by multiple high-severity heuristics for OLE activation and automatic linking. ClamAV identifies it as Rtf.Dropper.Agent-7701580-0, indicating its function as a dropper. The embedded OLE object data, specifically objdata_00_off00000495.bin, is the likely payload carrier, suggesting the document is designed to exploit OLE vulnerabilities for initial execution.
Heuristics 5
-
ClamAV: Rtf.Dropper.Agent-7701580-0 critical CLAMAV_DETECTIONClamAV detected this file as malware: Rtf.Dropper.Agent-7701580-0
-
Automatically linked OLE object high RTF_OBJAUTLINKRTF contains \objautlink — an automatically linked OLE object surface that can be updated or activated when Word opens the document.
-
\objupdate forces OLE activation high RTF_OBJUPDATERTF contains \objupdate — forces automatic OLE object instantiation when the document is opened, bypassing user interaction. Almost exclusively seen in Equation Editor exploit documents.
-
OLE object data medium RTF_OBJDATARTF contains 1 \objdata section(s) — embedded OLE objects
-
Suspicious extracted artifact medium 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.
