这题最大收获就是学习了一下DirectX HLSL,那些amp的函数我也没查到参数,只能无奈的随便猜猜了

验证流程都在这里:
.text:004035C0                 call    sub_401DF0               //输入转换base64
.text:004035C5                 call    sub_401E80               //一些初始化(seed/表/矩阵)
.text:004035CA                 call    @T0@0                    //Shader Model 5 Assembly (DirectX HLSL)
.text:004035CF                 call    @C0@0                    //没分析,直接单字节穷举,然后查表
.text:004035D4                 call    @T1@0                    //这个fork函数调试难受,容易卡住,最后利用最近学到的输出反馈给输入,很快发现了周期性,然后就好办了
.text:004035D9                 call    @C1@0                    //没分析,直接单字节穷举,然后查表
.text:004035DE                 call    @T2@0                    //没分析透彻,仿佛看到了傅里叶变换的味道,直接晚上开机穷举,早上起来出结果了

大部分时间都花在研究那个T0中那个HLSL验证上了
执行文件中有两段HLSL,偏移40102Ch处长度4CCh,偏移401530h处长度714h

可以直接用D3D反汇编:
void test_10_decompile(BYTE *dxbc_ptr,DWORD len)
{
        HMODULE hDxd;
        DWORD rv = 0;
        DWORD blob[0x400];
        DWORD D3DCreateBlob;
        DWORD D3DDisassemble;

        hDxd = LoadLibrary("D3dcompiler_47.dll");

        if (hDxd)
        {
                D3DCreateBlob = (DWORD)GetProcAddress(hDxd,"D3DCreateBlob");
                D3DDisassemble = (DWORD)GetProcAddress(hDxd,"D3DDisassemble");
                if (D3DDisassemble)
                {
                        rv = ((DWORD (__stdcall *)(DWORD,DWORD *))D3DCreateBlob)(0x400,&blob[0]);
                        rv = ((DWORD (__stdcall *)(BYTE *,DWORD,DWORD,char *,DWORD *))D3DDisassemble)(dxbc_ptr,len,0,"",&blob[0]);
                        //返回的反汇编数据在blob结构中,我直接内存抓出来了
                }
        }
}

第一段HLSL就是把输入的12字节按位拆开,利用GPU的96个线程,每个处理一位,大概可以这样模拟:
void hlsl1(DWORD *t,BYTE *in)
{
        DWORD i;
        
        for (i=0;i<96;i++)
        {
                t[i] = (*(DWORD *)&in[(i%3)*4] >> i/3) & 1;;
        }
}


第二段HLSL也是利用GPU的96个线程,每个处理一位,实现的模2矩阵乘法,大概可以这样模拟:
void hlsl2(DWORD *t,DWORD *array,BYTE *out)
{
        DWORD d,r;
        DWORD m;
        DWORD i,j;
        DWORD b;
        DWORD k[3] = {0xD76AA478,0xE8C7B756,0x242070DB,0};

        for (i=0;i<96;i++)
        {
                m = 0;
                d = i / 3;
                r = i % 3;
                for (j=0;j<0x20;j++)
                {
                        m += t[r+j*4] * array[d+j*0x20];
                }
                b = k[r] & (1 << d);
                b ^= (m & 1) << d;
                *(DWORD *)&out[r*4] ^= b;
        }
}

正规解法应该可以求出逆矩阵,以前有个软件winiso的注册算法用的就是这种模2矩阵,因为3个DWORD可以单独处理,在穷举承受范围内,所以还是穷举半小时出结果。

这题最大收获就是学习了一下DirectX HLSL,那些amp的函数我也没查到参数,只能无奈的随便猜猜了
