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

ini pseudocode utk binary1 tu
Code:
main()
{// addr = 0x080484B4
    intOrPtr _v8;                          // _cfa_fffffff8
    char _v20;                             // _cfa_ffffffec
    intOrPtr _v24;                         // _cfa_ffffffe8
    intOrPtr _v28;                         // _cfa_ffffffe4
    char _v32;                             // _cfa_ffffffe0
    char* _v48;                            // _cfa_ffffffd0
    _unknown_ __ebp;                       // r6

    __esp = __esp & 240;
    __esp = __esp - 48;
    _v8 =  *gs:0x14];
    _v32 = 1700947307; //ebek
    _v28 = 1634885998; //aran
    _v24 = 1818846318; //lidn
    printf("Kata laluannya sayang?");
    _v48 =  &_v20;
     *__esp = "%s";
    __isoc99_scanf();
    __eflags = strcmp( &_v20,  &_v32);
    if(__eflags != 0) {
        printf("Wrong password!");
    } else {
        printf("wemakeiteasyforyouthistime");
        printf("butbesureitwillbehardinthenextbinary");
        printf("youhavebeenwarned");
        printf("allthebestinyournextchallenges");
        printf("wehopeyouenjoyedthiseasychallenge");
        printf("uitmctf2012");
        printf("isthebestctfever");
    }
    if(__eflags != 0) {
        __stack_chk_fail();
        return 0;
    }
    return 0;
}

tapi still tak dapat jawapan betul dia OK

Code:
if(__eflags != 0) {
        printf("Wrong password!");
    } else {
        printf("wemakeiteasyforyouthistime");
        printf("butbesureitwillbehardinthenextbinary");
        printf("youhavebeenwarned");
        printf("allthebestinyournextchallenges");
        printf("wehopeyouenjoyedthiseasychallenge");
        printf("uitmctf2012");
        printf("isthebestctfever");
    }

Fuck That Shit
tu le flag dia
