解密self modify code

idc文件如下：

//encrypted.idc
//(c)  www.PEDIY.com 2000-2008

#include <idc.idc>
static decrypt(from, size, key ) { 
   auto i, x; 
   for ( i=0; i < size; i=i+1 ) { 
      x = Byte(from); 
      x = (x^key); 
      PatchByte(from,x); 
      from = from + 1;
   } 

} 
static main() { 
decrypt(0x00401060,0x15,0x1);
} 
 

如果遇到ida未識別十六進制數據，直接強轉為代碼即可。

FLIRT

能使IDA能在一系列編譯器的標準庫裏自動找出調用的函數

用法打開如下 signatures

導入我們想加載的庫的簽名文件

之後函數就出來了
