3W班试题1:
分析出KanxueSign函数的算法
对datadiv_decode64400029844576484运行时解密
通过frida对函数进行分析,可以将output分为3部分进行处理;
hook函数
分析出使用 firstInstallTime + startTime 进行后续运算
firstInstallTime + startTime
通过 (~v25 & 0xB5 | v25 & 0x4A) ^ 0xE9 运算 32字节变64字节
sub_1B2DC 入参如下:
疑似sha256
重点分析 sub_1D1E8 函数,
还原函数如下:
分析sub_26300
还原sub_26300
分析sub_1B89C
还原sub_1B89C算法
通过java层的 randomLong值的第一个数 查 dword_5C008
hook sub_F11C方法
魔改base64
魔改sha265 + 查表 + 魔改base64
