蟒蛇 |停止用户杀死进程

Question

这里提到了一个很酷的功能：

Prevent user process from being killed with "End Process" from Process Explorer

有谁知道如何将此 C++ 代码翻译成 Python（或重新编辑它，以便它至少可以在 C/C++ 中编译，假设它是这样的）：

static const bool ProtectProcess()
{
    HANDLE hProcess = GetCurrentProcess();
    EXPLICIT_ACCESS denyAccess = {0};
    DWORD dwAccessPermissions = GENERIC_WRITE|PROCESS_ALL_ACCESS|WRITE_DAC|DELETE|WRITE_OWNER|READ_CONTROL;
    BuildExplicitAccessWithName( &denyAccess, _T("CURRENT_USER"), dwAccessPermissions, DENY_ACCESS, NO_INHERITANCE );
    PACL pTempDacl = NULL;
    DWORD dwErr = 0;
    dwErr = SetEntriesInAcl( 1, &denyAccess, NULL, &pTempDacl );
    // check dwErr...
    dwErr = SetSecurityInfo( hProcess, SE_KERNEL_OBJECT, DACL_SECURITY_INFORMATION, NULL, NULL, pTempDacl, NULL );
    // check dwErr...
    LocalFree( pTempDacl );
    CloseHandle( hProcess );
    return dwErr == ERROR_SUCCESS;
}

这是您发布的代码的相当粗略的 ctypes 翻译。它甚至似乎工作！请注意，我删除了对CloseHandle 的调用，这是完全错误的。你不应该在伪句柄上调用CloseHandle，这是GetCurrentProcess 返回的。

from ctypes import *
from ctypes.wintypes import *
from win32con import *

class TRUSTEE(Structure):
    pass

TRUSTEE._fields_ = (
    ('pMultipleTrustee', POINTER(TRUSTEE)),
    ('MultipleTrusteeOperation', c_int),
    ('TrusteeForm', c_int),
    ('TrusteeType', c_int),
    ('ptstrName', LPSTR)
)

class EXPLICIT_ACCESS(Structure):
    _fields_ = (
        ('grfAccessPermissions', DWORD),
        ('grfAccessMode', c_int),
        ('grfInheritance', DWORD),
        ('Trustee', TRUSTEE)
    )

GetCurrentProcess = windll.kernel32.GetCurrentProcess
GetCurrentProcess.restype = HANDLE
hProcess = GetCurrentProcess()

denyAccess = EXPLICIT_ACCESS()
dwAccessPermissions = DWORD(GENERIC_WRITE|PROCESS_ALL_ACCESS|WRITE_DAC|DELETE|WRITE_OWNER|READ_CONTROL);

BuildExplicitAccessWithName = windll.advapi32.BuildExplicitAccessWithNameA
BuildExplicitAccessWithName.restype = None
DENY_ACCESS = 3
NO_INHERITANCE = 0
BuildExplicitAccessWithName(byref(denyAccess), 'CURRENT_USER', dwAccessPermissions, DENY_ACCESS, NO_INHERITANCE)

SetEntriesInAcl = windll.advapi32.SetEntriesInAclA
SetEntriesInAcl.restype = DWORD
SetEntriesInAcl.argtypes = (ULONG, POINTER(EXPLICIT_ACCESS), c_voidp, POINTER(c_voidp))
pTempDacl = c_voidp()
dwErr = SetEntriesInAcl(1, byref(denyAccess), None, byref(pTempDacl));

SetSecurityInfo = windll.advapi32.SetSecurityInfo
SetSecurityInfo.restype = DWORD
SetSecurityInfo.argtypes = (HANDLE, c_int, DWORD, c_voidp, c_voidp, c_voidp, c_voidp)
SE_KERNEL_OBJECT = 6
dwErr = SetSecurityInfo(hProcess, SE_KERNEL_OBJECT, DACL_SECURITY_INFORMATION, None, None, pTempDacl, None);

LocalFree = windll.kernel32.LocalFree
LocalFree.restype = c_voidp
LocalFree.argtypes = (c_voidp,)
LocalFree(pTempDacl)

使用ctypes怎么样？你也可以试试pywin32。您也可以尝试使用IronPython。对于 ActivePython，有 win32api。

另外，我不知道您为什么要实现这一目标的原因，这意味着可能有一些更优雅的解决方案可用。
