如何解释 Enigma Protector加壳的Emulated.Windows.APIs

2010-6-5 22:27

像如下l加壳的 Enigma Protector 1.9x,被保护是Delphi,一般的API可以修改像

mov edx,dword ptr ss:[ebp-4]
mov ecx,dword ptr ss:[ebp-10]
mov dword ptr ds:[edx+eax*4+4],ecx  // nop

但如同: 4083CC 的这行应该是Emulated.Windows.APIs保护吧,我不太了解这壳,不知该怎么处理好,试过将 00C700EF 这行的 330B 标记为 GetModuleHandleA等等,发现其它程序就不适应了,该如何处理如何是上策?有操作过的兄弟能否提点一下小弟 》》
