A few days ago, I started writing a series of articles about tools and methods for unpacking malware. Each piece of malware or packer is different, and sometimes a universal method cannot be used for unpacking. However, common characteristics can sometimes be found. For example, packers often use weak encryption algorithms, and breaking these algorithms … Read more
