We have trapped one of Melon Eusk's GaussBots™, given the right key we might get some Dogecoins out of them! But they are being evasive...
## Write up:
This program seemed to load the code in at runtime so I took a memory dump at runtime and found the following function:
```cvoid __noreturn sub_565D503C(){
  v0 = sys_read(0, v12, 0x1Fu);  strcpy(v11, "flag{pr0gram-inside-4-pr0gram}");  v2 = v1;  v3 = v11;  v4 = 30;  do  {    if ( !v4 )      break;    v5 = *v2++ == (unsigned __int8)*v3++;    --v4;  }  while ( v5 );  if ( !v4 )  {    strcpy(v10, "Wait, that is the password for the dogecoin vault... How?\n");    v6 = sys_write(1, v10, 0x3Au);    v7 = sys_exit(0);  }  strcpy(&v10[28], "I'll never tell you my secrets\n");  v8 = sys_write(1, &v10[28], 0x1Fu);  v9 = sys_exit(0);}```
The flag was:
```flag{pr0gram-inside-4-pr0gram}```
