Using unevaluated obfuscation methods has a significant risk since the methods might have some vulnerabilities. One evaluation for obfuscation is de-obfuscation which discloses the hidden information by the obfuscation. This paper proposed the de-obfuscation method against for DNR (dynamic name resolution) obfuscation method. DNR hides system-defined names by encrypting them and resolves names dynamically during runtime. This paper clarifies the steps of de-obfuscation and proposes static and dynamic manners to de-obfuscate DNR. Through the case study, two ways both succeed in disclosing the hidden information of DNR.
