Disclosed is a system and a method of detecting an abnormal act threatening to security based on artificial intelligence according to the present invention, and, more particularly, a system and a method of detecting an abnormal act threatening to security based on artificial intelligence that are capable of rapidly carrying out pre-processing of a large-scaled data set based on multi processing, and efficiently detecting the abnormal act threatening to security via various pieces of security device on the basis of studied artificial intelligence.

System and method of detecting abnormal act threatening to security based on artificial intelligence

A method for identifying a type of a variable within a binary performed on a computing device is provided. The method comprises, identifying a variable from disassembly code of a binary, and determining a type of the variable based on an instruction of the disassembly code, associated with the variable.

Method and device for identifying type of variable in binary

There is provided a method of patching a binary having vulnerability which is performed by a computing device. The method comprises loading a first binary to be patched, into a memory, generating a second binary by patching to call a stack frame initialization function from a vulnerable function of the first binary, executing the stack frame initialization function by calling the vulnerable function when the second binary is executed and initializing a stack frame area of the vulnerable function so as to automatically initialize a variable declared in the vulnerable function.
