[WarGame] fly me to the moon

갤로그 같은 게임이 하나 나오게 됩니다.

게임을 깨기 위한 점수로 31337점이라는 터무니 없는 점수를 요구합니다.

열심히 해도 30점을 넘기기 쉽지 않으니 다른 해결 방법을 찾아야 합니다.

소스를 확인해보면 packed된 javascript를 발견할 수 있습니다.

javascript unpacker 사이트에서 unpack을 해보면 아래와 같은 코드를 얻을 수 있습니다.

해당 코드는 게임을 진행하기 위한 정보가 있으며, 물론 점수에 관한 내용도 있을 것입니다.

그중 변수를 선언하는 var _0x32bb 를 먼저 확인 해봅니다.

모두 hex코드로 변환되어 있으니 python을 이용하면 간단하게 확인할 수 있습니다.

유심히 보면 %score= 라는 부분이 신경 쓰입니다.

_0x32bb[43]이 해당 부분이고 소스 코드에서 찾아보면 아래 부분에 있습니다.

_0x32bb[2] 부분이 score라는 것을 알 수 있고 찾아가 봅니다.

$[_0x32bb[44]](
{
    type:_0x32bb[40],url:_0x32bb[41],data:_0x32bb[42]+token+_0x32bb[43]+BTunnelGame[_0x32bb[2]](),success:function(_0x8618x19)
    {
        showHighScores(_0x8618x19)
    }
})

_0x32bb[2]은 _0x8618x7() 함수의 값을 가져오고, _0x8618x7() 함수는 _0x8618x6의 값을 return 합니다.

해당 값이 0으로 설정이 되어서 게임을 시작할 때 0점으로 시작하게 됩니다.

해당 값을 31337로 설정해 두고 console에 javascript를 실행하면 게임이 시작할 때 31337점으로 시작해 게임을 클리어 할 수 있습니다.

var _0x8618x6=0;
 
function _0x8618x7()
{
    return _0x8618x6
};
 
this[_0x32bb[2]]=function()
