PEB遍历进程加载模块

按照图片的步骤来

首先找到EPROCESS

以CMD.exe为例子

PROCESS 85fa2b38  SessionId: 0  Cid: 0fc8    Peb: 7ffda000  ParentCid: 05f8
    DirBase: 0f3c03a0  ObjectTable: e1fa93c8  HandleCount:  34.
    Image: cmd.exe

可以看到peb为 7ffda000  

进入进程空间

kd> .process 85fa2b38  
Implicit process is now 85fa2b38
WARNING: .cache forcedecodeuser is not enabled

查看PEB

可以看到我们的FullDLLName虽然显示不出但是我们可以验证下一个0x251f18

kd> dt _LDR_DATA_TABLE_ENTRY 0x251f18

   +0x000 InLoadOrderLinks : _LIST_ENTRY [ 0x251fc0 - 0x251ec0 ]

   +0x044 LoadedImports    : 0x4802bdc5 Void
   +0x048 EntryPointActivationContext : (null) 
   +0x04c PatchInformation : (null) 

然后再通过

 +0x000 InLoadOrderLinks : _LIST_ENTRY [ 0x251fc0 - 0x251ec0 ]

直到遍历回最初的模块就是的了
