위 함수를 보면 문자열과 특정 배열의 값들을 XOR연산을 통해 디코딩 하는 것을 볼 수 있다.

function _0x2c8aa3(_0x4cafb1) { var _0x4948f9 = [0x58, 0xe6, 0x3d, 0xc, 0x32, 0x48, 0x80, 0x24, 0x63, 0x3f, 0x9f, 0x80, 0xcc, 0xcd, 0x97, 0xd3, 0x39, 0xeb, 0x5e, 0x59, 0x79, 0xf7, 0x69, 0x7a, 0x28, 0xd8, 0xb8, 0x69, 0xfe, 0x2c, 0x1c, 0x43, 0x83, 0x75, 0x36, 0x6b, 0x20, 0x6, 0x29, 0x5c, 0x3, 0xdf, 0xf5, 0xbf, 0xc8]; for (var _0xdd156a = 0x0; _0xdd156a < 0x2d; _0xdd156a++) { if (_0x4cafb1[_0xdd156a] != _0x4948f9[_0xdd156a]) return ![]; } return !![]; } decoded_input = _0xf59727(_0xbaecb1), _0x2c8aa3(decoded_input) == !![] ? document[_0x3052a0(0xc2)]('result')[_0x3052a0(0xbf)] = '맞았어!' : document[_0x3052a0(0xc2)](_0x3052a0(0xc5))[_0x3052a0(0xbf)] = _0x3052a0(0xb8);

• _0xf59727 함수는 입력된 문자열을 디코딩 한다.
• _0x2c8aa3 함수는 디코딩된 값을 특정 값들 과 비교한다.
