1.findKey

打开是C++而且有点乱,所以找关键步骤有一个加密进去是不能反编译的,有花指令,

请添加图片描述

这里有重复的部分把下面的NOP掉,重新定义函数’p’

之后分析逻辑,

// positive sp value has been detected, the output may be wrong!
int __userpurge sub_40191F@<eax>(int a1@<ebp>, int a2, int a3, int a4, int a5)
{DWORD v5; // eaxint v6; // ediint v7; // eaxint v8; // eaxconst char *v10; // [esp-458h] [ebp-458h]CHAR *v11; // [esp-454h] [ebp-454h]v5 = strlen(v10);sub_40101E(String1, v5, v11);strcpy((char *)(a1 - 748), "0kk`d1a`55k222k2a776jbfgd`06cjjb");memset((void *)(a1 - 715), 0, 0xDCu);v6 = a1 - 715 + 220;*(_WORD *)v6 = 0;*(_BYTE *)(v6 + 2) = 0;strcpy((char *)(a1 - 760), "SS");*(_DWORD *)(a1 - 757) = 0;*(_WORD *)(a1 - 753) = 0;*(_BYTE *)(a1 - 751) = 0;v7 = strlen((const char *)(a1 - 748));sub_401005((LPCSTR)(a1 - 760), a1 - 748, v7);if ( _strcmpi((const char *)String1, (const char *)(a1 - 748)) ){SetWindowTextA(*(HWND *)(a1 + 8), "flag{}");MessageBoxA(*(HWND *)(a1 + 8), "Are you kidding me?", "^_^", 0);ExitProcess(0);}memcpy((void *)(a1 - 1016), &unk_423030, 0x32u);v8 = strlen((const char *)(a1 - 1016));sub_401005((LPCSTR)(a1 - 492), a1 - 1016, v8);MessageBoxA(*(HWND *)(a1 + 8), (LPCSTR)(a1 - 1016), 0, 0x32u);++dword_428D54;return 0;
}

其中的sub_401005函数一直跟进主要逻辑是:

unsigned int __cdecl sub_401590(LPCSTR lpString, int a2, unsigned int a3)
{unsigned int result; // eaxunsigned int i; // [esp+4Ch] [ebp-Ch]unsigned int v5; // [esp+54h] [ebp-4h]v5 = lstrlenA(lpString);for ( i = 0; ; ++i ){result = i;if ( i >= a3 )break;*(_BYTE *)(i + a2) ^= lpString[i % v5];}return result;
}

可知是异或操作,之后猜测是(a1 - 748)与(a1 - 760)异或之后得到的(a1 - 748)与String1做比较,让后下面还有一个sub_401005函数操作,我们可以得到unk_423030密文但是没有密钥,猜测是我们得到的String1即异或之后的(a1 - 748),可是在12行中有

sub_40101E(String1, v5, v11);

跟进是hash验证

int __cdecl sub_4013A0(BYTE *pbData, DWORD dwDataLen, LPSTR lpString1)
{DWORD i; // [esp+4Ch] [ebp-24h]CHAR String2[4]; // [esp+50h] [ebp-20h] BYREFBYTE v6[16]; // [esp+54h] [ebp-1Ch] BYREFDWORD pdwDataLen; // [esp+64h] [ebp-Ch] BYREFHCRYPTHASH phHash; // [esp+68h] [ebp-8h] BYREFHCRYPTPROV phProv; // [esp+6Ch] [ebp-4h] BYREFif ( !CryptAcquireContextA(&phProv, 0, 0, 1u, 0xF0000000) )return 0;if ( CryptCreateHash(phProv, 0x8003u, 0, 0, &phHash) ){if ( CryptHashData(phHash, pbData, dwDataLen, 0) ){CryptGetHashParam(phHash, 2u, v6, &pdwDataLen, 0);*lpString1 = 0;for ( i = 0; i < pdwDataLen; ++i ){wsprintfA(String2, "%02X", v6[i]);lstrcatA(lpString1, String2);}CryptDestroyHash(phHash);CryptReleaseContext(phProv, 0);return 1;}else{CryptDestroyHash(phHash);CryptReleaseContext(phProv, 0);return 0;}}else{CryptReleaseContext(phProv, 0);return 0;}
}

我们把得到的String1找网站解决,之后写代码即可

2.SoulLike

有一个关键函数sub_83A,之后是显示太大不可以直接查看源码,所以调节一下设置即可

去ida文件夹里面的hexrays.cfg,把max_function修改大一些(1024),

请添加图片描述

之后查看源码

 v4 = __readfsqword(0x28u);*a1 ^= 0x2Bu;a1[1] ^= 0x6Cu;a1[2] ^= 0x7Eu;a1[3] ^= 0x56u;a1[4] ^= 0x39u;a1[5] ^= 3u;a1[6] ^= 0x2Du;a1[7] ^= 0x28u;a1[8] ^= 8u;++a1[9];a1[10] ^= 0x2Fu;a1[11] ^= 0xAu;++*a1;a1[1] ^= 0xDu;a1[2] ^= 0x73u;a1[3] ^= a1[2];a1[4] ^= 0x37u;++a1[5];a1[6] ^= 0x69u;a1[7] ^= 0x59u;a1[8] ^= 0xCu;a1[9] ^= 0x70u;++a1[10];a1[11] ^= 0x1Fu;++*a1;a1[1] ^= 0x55u;a1[2] ^= a1[1];a1[3] ^= 0x72u;.....

可知是一群异或,并且每一位可能与上一位有关系,我们可以一个一个查找,写代码即可

我们知道需要一直循环找到flag,使用符号执行:

符号执行（Symbolic Execution）是一种程序分析技术。其可以通过分析程序来得到让特定代码区域执行的输入。使用符号执行分析一个程序时，该程序会使用符号值作为输入，而非一般执行程序时使用的具体值。在达到目标代码时，分析器可以得到相应的路径约束，然后通过约束求解器来得到可以触发目标代码的具体值。[1] 符号模拟技术（symbolic simulation）则把类似的思想用于硬件分析。符号计算（Symbolic computation）则用于数学表达式分析。我理解为更厉害的爆破。

基础语法:

import angrproj = angr.Project('文件名') #新建一个工程
init_state=proj.factory.entry_sate() #设置程序的入口
sm=proj.factory.simulation_manager(init_state) #执行程序
sm.explore(find=0x.....，avoid=0x.....) #执行到某个条件,避免某个条件sm.found[0] #找到符合条件的值
found_state=sm.found[0]
found_state.posix.doumps(0)  #获得我们最开始的输入
found_state.posix.doumps(1)  #获得我们最后的输出

脚本例子:

import angr
import sysdef main(argv):p = angr.Project('')initial_state = p.factory.entry_state()sm = p.factory.simgr(initial_state)sm.explore(find=good_addr, avoid=bad_addr) if sm.found:flag = sm.found[0]print(flag.posix.dumps(sys.stdin.fileno()))else:raise Exception('Cannot find')
if __name__ == '__main__':main(sys.argv)

脚本解密:

import angrp = angr.Project(r'C:\Users\21901\Desktop\signal.exe')
state = p.factory.entry_state()
simgr = p.factory.simgr(state)
simgr.explore(find=0x0040179E, avoid=0x004016E6)
flag = simgr.found[0].posix.dumps(0)[:15]
print(flag)#b'757515121f3d478'

得到flag{757515121f3d478}

}

前面是正常的输入账号密码代码,并判断是不是数字和字母,之后我们需要break出while死循环,需要满足sub_401830函数返回1,跟进查看

}

需要满足v13 == 0xAB94也就是v13 == 43924,查看v13可知与sub_401470函数有关

其中的v16与sub_401710(v16, a1, v5++);函数和 v16[v5] = byte_416050[(v7 + v12)] ^ v15[v4 - 1];异或操作有关,

首先看sub_401470函数

unsigned int *__usercall sub_401470@<eax>(int a1@<ebx>, _BYTE *a2, unsigned int *a3)
{char v5; // alunsigned int *result; // eaxif ( *a2 != 0x64 )*a3 ^= 3u;else*a3 |= 4u;if ( a2[1] != 0x62 ){*a3 &= 0x61u;_EAX = *a3;}else{_EAX = a3;*a3 |= 0x14u;}__asm { aam }if ( a2[2] != 0x61 )*a3 &= 0xAu;else*a3 |= 0x84u;if ( a2[3] != 0x70 )*a3 >>= 7;else*a3 |= 0x114u;if ( a2[4] != 0x70 )*a3 *= 2;else*a3 |= 0x380u;if ( *(NtCurrentPeb()->ProcessHeap + 3) != 2 ){if ( a2[5] != 0x66 )*a3 |= 0x21u;else*a3 |= 0x2DCu;}if ( a2[5] != 0x73 ){v5 = a3;*a3 ^= 0x1ADu;}else{*a3 |= 0xA04u;v5 = a3;}_AL = v5 - (~(a1 >> 5) - 1);__asm { daa }if ( a2[6] != 0x65 )*a3 |= 0x4Au;else*a3 |= 0x2310u;if ( a2[7] != 0x63 ){*a3 &= 0x3A3u;return *a3;}else{result = a3;*a3 |= 0x8A10u;}return result;
}

每一次的if语句都和字母的判断有关也就是猜测需要满足所有的else语句,可以验证一下

因为结果是,我们计算一下看看是否相等,其中的

if ( *(NtCurrentPeb()->ProcessHeap + 3) != 2 )

这行代码的作用是检查当前进程的默认堆的某个偏移位置的值是否不等于 2

这种对 PEB 或堆的直接访问和判断可能是某种反调试机制,我们可以都试试来找到a3==43924的情况

#include<stdio.h>int main(){int a=0,s;s=a|4|0x14|0x84|0x114|0x380|0xA04|0x2310|0x8A10;if(s==43924){puts("right");}else{puts("wrong");}return 0;//right
}

#include<stdio.h>int main(){int a=0,s;s=a|4|0x14|0x84|0x114|0x380|0x2DC|0x2310|0x8A10;if(s==43924){puts("right");}else{puts("wrong");}return 0;//wrong
}

所以a2也就是v16是dbappsec

int __cdecl sub_401710(int a1, const char *a2, signed int a3)
{int result; // eaxsigned int v4; // [esp+4h] [ebp-58h]struct _STARTUPINFOW StartupInfo; // [esp+14h] [ebp-48h] BYREFmemset(&StartupInfo, 0, sizeof(StartupInfo));StartupInfo.cb = 68;GetStartupInfoW(&StartupInfo);v4 = strlen(a2);if ( StartupInfo.dwX|| StartupInfo.dwY|| StartupInfo.dwXCountChars|| StartupInfo.dwYCountChars|| StartupInfo.dwFillAttribute|| StartupInfo.dwXSize|| StartupInfo.dwYSize ){if ( a3 <= v4 )return &a2[a3];elsereturn &a2[v4];}else if ( a3 <= v4 ){result = a2[a3] ^ *(a3 + a1);*(a3 + a1) = result;}else{result = a3 + a1;*(a3 + a1) += byte_416050[v4 + a3] & a2[v4];}return result;
}

之后查看sub_401710函数的实参,v16是密文,a1是账号,v5是计数器且该函数是在 while ( v5 < 8 )循环中进行的所以v5最大为7,而我们账号welcomebeijing长度是14一直比v5大,所以

v4 = strlen(a2);就是账号的长度,所以a3 <= v4一直成立,其中的第一个if语句

if ( StartupInfo.dwX|| StartupInfo.dwY|| StartupInfo.dwXCountChars|| StartupInfo.dwYCountChars|| StartupInfo.dwFillAttribute|| StartupInfo.dwXSize|| StartupInfo.dwYSize )

是检查窗口是否已配置,我也不知道他配置没配置,所以可能异或也可能不异或,存疑,猜测和打开方式有关

所以关键之处就是

直接return不进行操作,或者是

 result = a2[a3] ^ *(a3 + a1);*(a3 + a1) = result;

可知这是账号的前八位和v16的前八位异或得到v16

我们要得到的是v15

分析逻辑

请添加图片描述

这里是把密码转成16进制数,之后储存在v15中进行加密计算

v16[v5] = byte_416050[(v7 + v12)] ^ v15[v4 - 1];

这里我们知道了v16,其中的byte_416050可以动态调试查看其中我们需要的8位

其中要把动态调试监测的代码nop掉,就是上面分析的和动态调试有关的代码NtCurrentPeb这种的都nop掉

请添加图片描述

得到的ecx的值是0x2A,0xD7,0x92,0xE9,0x53,0xE2,0xC4,0xCD

写代码解决

#include<stdio.h>int main(){char a[]="dbappsec";char zh[]="welcomebeijing";int i,j;//for (i=0;i<=7;i++){//	a[i]^=zh[i];//}int key[]={0x2A,0xD7,0x92,0xE9,0x53,0xE2,0xC4,0xCD};for (i=0;i<=7;i++){a[i]^=key[i];printf("%02x",(unsigned char)a[i]);//直接异或的 //4eb5f3992391a1ae  d2be2981b84f2a905669995873d6a36c//异或账号前八位的://39d09ffa4cfcc4cc  84ab2835640e510eb81f86e0ced4d91c}return 0;
}

最后都试试是可知是flag{d2be2981b84f2a905669995873d6a36c}
