摘要： The present disclosure pertains to a system configured to prepare and use prediction models for software diversification. Some embodiments may: obtain compilation data; identify a plurality of blocks from the compilation data; and pad each of one or more blocks of the plurality of blocks by a random amount such that executable instructions within the each block begin at a different location to prevent a deterministic memory addressing attack, none of the one or more blocks being a beginning block of the compilation data.
