i wanna know is there any better program that crack sam db then lc4 ,
cuz lc4 is 50% cracking...
if there is a better one plesae post a link to the program ,

greetz

Yea, you can use RainbowCrack... it here:
RainbowCrack Tutorial
It takes some time to generate the actual tables, but once they are generated, you can crack lanman hashes very quickly. For example...

thanx for the help will try the other program

the time-memory-tradeoff technique used by rainbowcrack is the best bet you can go with cracking passwords IMHO. I have been using it ever since and I strongly suggest it to everyone as well. Only problem is that you need a few GBs of free space, but that shouldn't be the problem.

Try Cain & Abel or John The Ripper

RainbowCrack seem to kick some ass!

The only problem that I've seen with rainbow crack is the ridiculous amounts of space it takes up. If you want to be able to crack passwords 12 characters in length or greater, the space is astronomical. LC4 can crack these in a few days. Sure you gain the speed with Rainbow tables, but you only really see the advantage if you can keep and reuse the tables, and if you want to crack complex passwords, that's a lot of storage.

well the problem is the lc4 is not very good program for cracking...
it's taking lot's of time, and it's sometime do not cracking the password

Use Cain & Abel. Is good program

There is a thread currently on the knoppix-std forums where multiple users are creating tables and attempting to correlate everyones work. As with most virtual projects it seems to be in some dissarray, but if they succeed they may have an albeit large but downloadable series of hash tables. I have never used this utility before but it is on my short list of tools to become familiar with.

<edit> Just visited there and they appear to be having database problems on the forum.

and there is always SAMInside.... fastest bruteforce windows password cracker... written in ASM...

search this forum under downloads section

I use John the Ripper for its excellent cracking algorithm, it works much faster than LC4 for me and doesnt rape my CPU. If I get a larger HDD, then I'll try out rainbow crack =D

(for comparison purposes, how big is a 8character table?)

Ah ok, thanks. And yes you did do it right, exponential would be x^n, but if it grew linear system then it would just be x+n, which would be nice and small =D. I'm going to be picking up another hdd soon anyways, probably 160gb, I hope it can hold some tables without taking up too much space.

In our company we use for these things a special PC with big HDD, RAM and CPU.
We use LC4, rainbowcrack, john and so on - so i can not say which tool is the best.

Bye

well i tryed Cain v2.5 and i still cant crack it
is there a program that will 100% crack the passwords ?

I suggest John the Ripper. It's never let me down in the past and usually I can wake up in the morning with a nice list of passwords.

my 450 GB will prolly do the job
Just to lazy to write cd's, just keep putting in HD's instead

rainbow crack works nice .

I used LC4 in 2 modes.

1. Singel Pc Cracker, I cracked the sam in a few days 2/2.5?
then i used its distrubided feature between 3 pcs
1.p4 2.4 l 512 ram
2.dual p3 450 | 512 ram
3. Celorn 1.3? | 128/256 ram

1- Got done in a few hrs,under 5
2-took 18 hrs?
3-take 5-9 hrs.

and it sucked major balls!
Didnt even get the same results as I did the standalone test.

psssh waste of time.

btw, anyone have any cheap HDDs for sale? =D my 80 won't cut it for RainbowCrack

SyN/AcK maybe you could help me configer LC4, cuz all im doing is importing the file and then pressing start(it is taking 4-5 h in my 2ghz p-4) when it's 100% im getting this kind of resullts ?????3ter.

I think you need a larger character set. Or just use John The Ripper, it'll crack it

If u can guess something about the pwd, try using RegEx with http://www.nestonline.com/lcrack/ (text) or this http://www.nestonline.com/lcrack/lcFE.htm (GUI)

U can find even passwords with binary characters

how must i precompute a table in rc to have capital and normal letter ? e.g. :
cR4ck_iT

I`ve used Cain , Lc4 and Rainbow ...
all , for cracking mass SAM files ,

as i played with them a lot i understood :

Cain and Lc4 are good for few number of passwords to crack
, Cain get more cpu useage and calculate more hashes per minute than Lc4
but the Lc4 method is better ( it`s greatly optimised ) .
Cain also support new protocols to decode and extract passwords
( sniffing them ) ,. but lc4 seems week in this case.

I`ve really never used Rainbow for few number of passwords .
but it really rocks for mass SAM`s....

cracking a SAM containing 20,000 accounts with Cain , u should go and die .
Cain is NOT designed for multi-threat cracking .
with Lc4 , mmm works nice but at least 2 days ( with my PIII-8666 ) .
Lc4 have a specific method , wich is unique . the " Hybrid crack " .
passwords are between 4 and 8 characters .
but u should spend some $`s to get Lc4 work for u .
the " U " does not contain those who have obtained it`s keygen

but in such situation ( large number of passwords ) ,
Rainbow , really rocks ! the only time it takes u it to build it`s table .
after that , u just sit and count

btw , i forgot Dic. based attackes...
try Cain , if u think ur Dic. is strong enough , but
if u wanna optimise ur Dic ( adding chars. to dic words or alike )
Lc4 works great . but again , Cain count more words than Lc4 per minute.

now i give u a little hint , to increase the cracking speed
set the priority level of ur program ( specially for Cain ) to the highest
level , but in this way , u`ll lose ur PC it works only for ur cracker
and won`t respond u



if u know how long ur passwors is , Cain is the best ,
it`s easy to determine , open ur SAM with LC4 and see >8 or <8 !

but after all of these ,it`s ALL depended on ur CPU speed .

hope these help

=/ all of these i wrote , are based on MY cpu ! a PIII-866 . /=
