T1203 Exploitation for Client Execution
The sample is a Microsoft Word document containing an embedded Equation Editor OLE object, which is a known vector for exploiting the Equation Editor vulnerability (CVE-2017-11882). This vulnerability allows for remote code execution when the document is opened. No document body text or scripts were extracted, but the presence of the vulnerable OLE object strongly suggests an exploitation attempt.
Heuristics 2
-
Equation Editor Ole10Native payload — CVE-2017-11882 critical CVE likely CVE_2017_11882_EQUATION_OLE10NATIVEAn embedded Microsoft Equation 3.0 object (CLSID 0002CE02-0000-0000-C000-000000000046) carries an Ole10Native packager stream instead of the normal Equation Native/MTEF data. This is the weaponized Equation Editor RCE delivery shape used by CVE-2017-11882 / CVE-2018-0802 maldocs. The payload (font-record overflow + shellcode) is frequently encrypted and the stream name case-scrambled to evade scanners, but an Equation object holding an Ole10Native stream has no benign use.
-
Equation Editor OLE object high OLE_EQUATION_EDITORContains Equation Editor object — related to CVE-2017-11882 / CVE-2018-0802 exploitation, but CLSID presence alone is not the malformed MTEF exploit primitive.
