The file is an RTF document containing embedded OLE objects, specifically triggering heuristics related to Equation Editor exploits. The critical ClamAV detection explicitly names Rtf.Exploit.CVE_2018_0802-6825822-0, indicating a known vulnerability in Microsoft Equation Editor is being leveraged. This suggests the primary attack pattern is to trick the user into opening the document, which then exploits CVE-2018-0802 to achieve arbitrary code execution.
Heuristics 5
-
Ole10Native stream in RTF OLE object high RTF_OLE10NATIVE_STREAMRTF contains an embedded OLE object with an Ole10Native stream. This is a strong payload-container signal and is related to Word/OLE exploit delivery, but it is not specific enough on its own to assign a CVE.
-
Equation Editor CLSID critical RTF_EQUATION_EDITOREquation Editor OLE CLSID found inside an OLE object — exploited by CVE-2017-11882 / CVE-2018-0802 / CVE-2018-0798
-
ClamAV: Rtf.Exploit.CVE_2018_0802-6825822-0 critical CLAMAV_DETECTIONClamAV detected this file as malware: Rtf.Exploit.CVE_2018_0802-6825822-0
-
\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 2 \objdata section(s) — embedded OLE objects
