T1203 Exploitation for Client Execution
T1559.001 Component Object Model Hijacking
The critical heuristic firing for CVE-2017_11882_EQUATION_OLE10NATIVE indicates exploitation of a known Microsoft Office vulnerability. The presence of an OLE object containing an Equation Editor payload strongly suggests this exploit is used for initial execution. No document body text was available for further analysis, but the exploit itself is sufficient evidence of malicious intent.
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.
