64位支持。Finally properly encoded x64 shellcodes !新的更小的解码器存根。LFSR key reduced to 1 byte具有伪随机模式的编码存根。Decoder stub is also encoded with a psudo random schema没有可见的循环条件Stub decodes itself WITHOUT using any loop conditions !!解码器存根混淆。Random garbage instruction generator added with keystone安全注册选项。Non of the registers are clobbered (optional preable, may reduce polimorphism)
