This paper is a continuous work of my previous published article (RCE Profiling: Counterbalancing the Algo.this.Key) at CodeBreakers Journal Vol. 4, No. 1, 2007. What I’ll try to establish in this paper is to continue the analysis of another KGM; Keygen it to a higher level of simulation, blowing up the SCA, inline assembly code. The new thing is how to find the bugs inside the compiled executable file and how to deal with them so that not to expose your software for malicious attacks based on a hidden bug prior to a low beta testing process. This accomplished with a detailed scrutiny of the overall construction of the code. The main objective is to concentrate on the debugging analysis and how to conduct a meticulous verification for any misbehave upon beta testing process. Software engineering the bugs with a degree of optimization using code injection so that to circumvent the unpredictable crash or fault answers. The methods used to perform this task, that is, analytical, numerical, and experimental.
