Researchers will present their findings at Black Hat USA 2015 at 3:50pm in South Seas IJ. The tool is designed to remove unused functions from Dynamic Link Libraries (DLLs) DLLs are loaded by applications so that they can use the functions they are not needed. It freezes the code base of the program, i.e., it denies adding or modifying executable memory pages. As a result, attackers can no longer inject additional code into the process. The tool then overwrites the unused functions code in memory.”]
