A method for evaluating the risk of data leakage in an application includes the steps of: extracting a DEX (Dalvik Executable) file and a so (Shared Object) file by decompressing an APK file of a mobile application; extracting DEX code information from the DEX file by parsing the DEX file; translating a content of the so file into IR (Intermediate Representation); extracting IR code information from the translated IR; generating a call-reference structure between the DEX file and the so file by processing the extracted DEX code information and the extracted IR code information; and outputting weakness information according to a risk designated in advance based on the generated call-reference structure. Accordingly, it is possible to extend the call-reference coverage of an android application.

Method for evaluating risk of data leakage in application, recording medium and device for performing the method

According to some embodiments, a semiconductor device may include gate structures on a substrate; first and second impurity regions formed in the substrate and at both sides of each of the gate structures; conductive line structures provided to cross the gate structures and connected to the first impurity regions; and contact plugs connected to the second impurity regions, respectively. For each of the conductive line structures, the semiconductor device may include a first air spacer provided on a sidewall of the conductive line structure; a first material spacer provided between the conductive line structure and the first air spacer; and an insulating pattern provided on the air spacer. The insulating pattern may include a first portion and a second portion, and the second portion may have a depth greater than that of the first portion and defines a top surface of the air spacer.
