substitution chiper kot,
Code:
A => K     
B => X    
C => V    
D => M    
E => C    
F => N    
G => O    
H => P
I => H    
J => J    
K => R    
L => S    
M => Z    
N => Y    
O => I    
P => J
Q => A    
R => D    
S => L    
T => E    
U => G    
V => W    
W => B    
X => U
Y => F    
Z => T

nanti dapat la flag macam p0pc0rn bgtau tu

Code:
http://en.wikipedia.org/wiki/Universiti_Teknologi_MARA

ini pseudocode utk binary1 tu
Code:
int __cdecl main()
{
  int v0; // ecx@2
  int result; // eax@4
  signed int v2; // [sp+14h] [bp-1Ch]@1
  signed int v3; // [sp+18h] [bp-18h]@1
  signed int v4; // [sp+1Ch] [bp-14h]@1
  char v5; // [sp+20h] [bp-10h]@1
  int v6; // [sp+2Ch] [bp-4h]@1

  v6 = *MK_FP(__GS__, 20);
  v2 = 1700947307;
  v3 = 1634885998;
  v4 = 1818846318;
  printf("Kata laluannya sayang?");
  __isoc99_scanf("%s", &v5);
  if ( strcmp(&v5, (const char *)&v2) )
  {
    printf("Wrong password!");
  }
  else
  {
    printf("wemakeiteasyforyouthistime");
    printf("butbesureitwillbehardinthenextbinary");
    printf("youhavebeenwarned");
    printf("allthebestinyournextchallenges");
    printf("wehopeyouenjoyedthiseasychallenge");
    printf("uitmctf2012");
    printf("isthebestctfever");
  }
  result = 0;
  if ( *MK_FP(__GS__, 20) != v6 )
    __stack_chk_fail(v0, *MK_FP(__GS__, 20) ^ v6);
  return result;
}

tapi still tak dapat jawapan betul dia OK
