本题最终 flag 为验证正确时的字符串加上逆向分析得到的所有生物特征值之和的 md5 (小写)。
比如,验证通过后显示的字符串为UniCTF{abcd},分析得到的正确生物特征值为速度 11、抖动 33,生物特征值之和为 44,注意生物特征值通常不会太大,则最终的 flag 就是
tips:

题目描述更新为UniCTF{md5(UniCTF{abcd}44)}

Providing final flag and explanation

The final flag is UniCTF{32f9b4c728f42db8ecd6d631cc950495}. The flag follows the updated format in the challenge description. The sum of the features (L=20, speed=15, jitterY=88, jitterX=42) equals 165, which led to our computed result. We should mention the flag and feature values clearly and answer in both English and Chinese as needed!

Trả lời

从你贴出来的 verify_human 的 wasm 逻辑里可以直接看出来:

  • 先从轨迹里算出 4 个“生物特征值”(都被截断成整数)并打包成 64-bit seed:
    • A = floor(0.16 * len)(放在高 16 位)
    • B = floor(totalDist / len)(放在次高 16 位)
    • C = floor(2 * avgYJitter)(放在低 32 的高 16 位)
    • D = floor(2 * avgXJitter)(放在最低 16 位)
  • 然后用 LCG:
    • seed = seed * 6364136223846793005 + 1442695040888963407 (mod 2^64)
    • 每轮取 seed >> 56 作为 1 字节 keystream
    • 去 XOR 解出 46 字节字符串(显示在页面上)

把 data 段里那 46 字节密文按上面 LCG 逆出来,能得到唯一通过前缀校验的特征值组合:

  • A=20, B=15, C=88, D=42
  • 特征值之和:20 + 15 + 88 + 42 = 165

验证通过时显示的字符串是:

UniCTF{Hum4n_Err0r_1s_The_Tru3_P4ssw0rd_8x92a}

按题面更新:最终 flag 为 UniCTF{md5(验证字符串 + 特征和)}(md5 小写),即对下面字符串做 md5:

UniCTF{Hum4n_Err0r_1s_The_Tru3_P4ssw0rd_8x92a}165

得到 md5:

32f9b4c728f42db8ecd6d631cc950495

所以最终 flag 是:

UniCTF{32f9b4c728f42db8ecd6d631cc950495}
