Subject: hash from pwdump and external functions
Hi,
I donwload a hash from a Windows 2000 target using pwdump6.
The first half of the password it will cracked using LC5.
With the second half I have some problem and I am afraid I do some mistake.
I wonder in the second half are some special character and I try to use
the external functions of John.
The external function is:
**********************************************************************
[List.External:prepend-pims]
void init()
{
int i;
word[0] = 'A';
word[1] = '%';
word[2] = 'D';
word[3] = 'M';
word[4] = 'I';
word[5] = 'N';
word[6] = '7';
word[7] = 'I';
word[8] = 0x20;
word[9] = 0x20 - 1;
word[10] = 0x20 - 2;
word[11] = 0x20 - 3;
word[12] = 0x20 - 4;
word[13] = 0x20 - 5;
}
void generate()
{
int i;
i = 13;
while (++word[i] > 0xff)
if (i > 8)
word[i--] = 0x20;
else {
word=0;
return;
}
}
**********************************************************************
but when I launch,
john -session=pims -format=NT -e=prepend-pims hash-pims.txt
the output if,
"No password hashes loaded"
if I launch,
john -session=pims-NTLM -e=prepend-pims hash-pims.txt
the output is
Loaded 1 password hash (NT LM DES [128/128 BS SSE2])
guesses: 0 time: 0:00:00:03 c/s: 9502K trying: A%DMIN7 - A%DMIN7
,... it seem they are not able to see the second half.
if I launch,
john -session=pims-NTLM -format=mscash -e=prepend-pims hash-pims.txt
the output is
Loaded 1 password hash (M$ Cache Hash [Generic 1x])
guesses: 0 time: 26:22:05:42 c/s: 2681K trying: A%DMIN7I+,UqO¬ - A%DMIN7I+,UqO–
It try the whole password but the format it is mot mscash !!!
The hash is,
administrator:8ED0A046696658941180BC49698B0D39
What is wrong in my exam I doing wrong external function?
