위의 코드에서 절망을 느끼시면 안 됩니다.
차근차근 합시다.
일단, 처음에 debug me 라고 alert 함수가 띄워졌던 것을 눈치채셨을 것입니다.
그렇다면, alert() 함수가 있는 곳을 먼저 찾아보도록 합시다.
아래와 같이 한 군데 밖에 찾질 못했습니다.
setInterval(function() {
H();
}, 0xfa0);
if (location[b('0x19', 'iUmC')][b('0x1a', '6]r1')](0x1) == b('0x1b', 'RLUb')) location[b('0x1c', '4c%d')] = b('0x1d', 'llaF');
else alert(b('0x1e', '14cN'));
흠.... 값을 조작하기 위한 조건이 어떤 건지 잘 이해가 안 갑니다.
대략적으로 분석해보니, if문일 때는 alert가 없습니다.
그러면 일반적일 때는 if문 내부가 동작하지 않고, else가 동작하는 것으로 보입니다.
그렇다면 else 부분이 debug me를 출력하는 alert 구문이라고 했을 때, if문에서 가지고 있는 b('0x1d', 'llaF') 이녀석은 무엇일지 살펴보았습니다.
호오?
풀이 끝
