Debugging multi-rules

April 5, 2016, 3:07 pm

Hi,

I'm almost sure there's already a post about this, but I couldn't find it using Google and the forum search. I'd like to use the multi-rules feature in oclHashcat, but want to make sure my rules are working as intended (-> the correct candidates are generated). However, oclHashcat doesn't support the --stdout parameter, while hashcat doesn't support multi-rules. Is there anyway to debug multi-rules as I'm trying to or do I have to debug the rules one by one and then hope that the combination is done as I'm assuming?

Kind regards and thanks in advance,
Prime

3 Questions:kHs, No Fan RPM, Speed

Hey folks,

I have two GTX 970 on SLI.

[Image: h0NJt3C.png?1]

After I've started oclHashcat with a WPA hash I was wondering the following:

1.- How many hashes per second represents 296.4 kH/s, or how many hashes are 1kH/s? 
I'm pretty sure this has been already answered but I could not find the answer around.
2.- Why the GPU#2 is showing 0rpm?
3.- I'm having a decent cracking speed?. 
I've installed everything but I'm not sure if that's a decent speed or not. Since I every time I do a benchmark, my screen goes black and just stops until I do a hard reset, so I'm not sure if everything is working as expected or not.

Thanks!

Multi-CPU utilization for combinator attack on a modern GPU

Greetings,

I've read several posts detailing the CPU bottleneck that occurs during combinator attacks (CPU can't generate combinations fast enough for the GPU). Although I am aware of mask/rule workarounds for this issue, I'm wondering whether anyone has successfully employed multiple CPUs, seated on the same motherboard, (or a CPU cluster) to widen this choke point substantially at a reasonable price?

Hi everyone.  I currently have a Reference HD 7970.  And I'm trying to Crack a handshake.  The mask is 10 digits  ?d  at this time it's takin 23hrs to Crack it.   I can borrow a asus 970.  My question is how much faster the process will be? And if it's possible to run both gpus t the same time.  Thanks

First Time User - MD5 Help ("Updating" password w/ digits)

April 9, 2016, 9:36 am

As title says, I'm a first time user. I've read through the documentation and I understand how to run the program with its parameters and such. I can't seem to find in the documentation what I am trying to do and I was wondering if someone might be able to point me in the right direction.

I have a "password" of sorts with known length (145 combinations of 2 digit integers from -1 to 36 with spaces in between). Example:
Code:
17 -1 00 33 18 12 -1 20 12 -1 31 04 33 30 01 34 11 00 01 13 19 27 11 19 16 23 09 00 16 21 06 09 14 09 07 03 11 28 02 22 25 13 15 34 10 23 14 22 35 00 26 23 09 13 29 34 08 31 21 27 23 13 33 36 30 27 02 10 08 03 13 31 05 08 13 22 18 35 17 01 36 30 33 05 05 27 05 29 04 11 05 25 11 23 -1 34 08 16 04 24 14 10 34 03 10 15 33 20 25 04 12 18 13 00 34 30 26 33 36 24 22 20 29 28 13 18 01 35 00 30 21 32 06 28 08 35 04 16 21 33 24 08 25 22 12

The last 25 combinations are used as a form of "salt" in it's own sense. Crunching the numbers shows that there are (145 numbers)*(38 possibilities)*(2 digits per possibility) = 11,020 possibilities. I obviously know that this would be possible to solve using oclHashcat for MD5 (I forgot to mention it's MD5 encoded). I am wondering what I can do to indicate to oclHashcat that there are spaces after each combination of 2? Each one of the numbers also outputs after 30 seconds so if there might be a way to feed an "update" to oclHashcat indicating that the digits are known since this would exponentially decrease the amount of possibilities every 30 seconds.

I'm using oclHashcat for CUDA drivers on my GTX 970M. If someone could help me with known ways to do this, or point me in the right direction that'd be helpful! Big Grin

P.S. I think my graphics card is good enough for this, but could someone aid me in figuring out how long it might take to break this hash?

If you're unaware Microsoft added Bash support in the latest Windows 10 (Build 14316).  Thought I'd give hashcat a try and it works!

Had to install texinfo from repository manually (probably other packages as well I'm forgetting) but was able to compile from GitHub source.

Code:
root@localhost:/mnt/c/Users/forumhero/hashcat# ./hashcat-cli64.bin -b

Hash type: MD5

This is awesome because we can now run Windows as the OS and have the ability to compile latest code for hashcat and other tools as well.

Question on hardware lifespan

April 12, 2016, 2:03 pm

Hey guys,
I was wondering how long is the average lifespan of your cards... I'm building a computer from scratch and I'm thinking about purchasing a single GTX 970 to try my hand at password cracking. Now, this is a really amateur setup, but I don't plan on cracking passwords 24/7 for a year, this is not the main purpose of this box. It will be, however, one of the main purposes for the graphics card, as I rarely game... So I was wondering if the card is stuck with an hash for a couple of months, how long can I expect the card to withstand the abuse? I'm planning on a fairly decent air cooling setup and I'll be closely monitoring the temperatures...

Thanks!

Hi,

Are you always launching a forum poll before deciding which new algorithms to implement to the next version?

Support for Nvidia GeForce 9300M GS

Hi, i only have macbook air I7 2014, but it have bad GPU (Intel Graphics 5000) and Old PC with GeForce 9300M GS. But it is not supported by olcHashcat, also tried old versions like 1.35 and 1.20, changed time and date of PC, but no luck.. It say that "Shader Model 1.0 - 1.3 Based GPU Detected".. What version you recomend use?
Right now i only can run Hashcat on macbook (VMware Kali linux), its using CPU and is very slow (1600 WPA2 passwords/second).. I think that even old video card would be able to decode WPA2 Passsword fastest way that CPU running over VMWARE on MAC.. Buy new Graphic card, isnt option to me as this old PC is ALL in One..
Thank you guys !

Hashcat rules handling (native *.rule files) added to JtR

April 17, 2016, 6:18 am
$

JtR (bleeding-jumbo), can now handle the native hashcat .rules files.  There is also a document added to the john package, listing the syntax needed to be added to make it work (mostly to work around escape character requirements for some rules in john, due to the pre-processor).

The addition of these rules has shown a few differences between the tools.  The differences are on 'edge' conditions.  The notable rules are i x and O.

hashcat logic is to leave word alone, unless the letter (or full range of letters) are within the word.

john logic is to do 'best case' mangling, where if any of the range is in the word, then that is done, and for the 'i', if the insert is past end of word, it is treated as a $

The way I have implemented rules in 'hashcat logic' mode, I get the same results from john as from hashcat.  But it may be nice to have both tools producing the same candidate stream from the same input words and rule set.

Not sure how to crack a chained SHA-256 hash

I've got a chain of hashes where each one is put through SHA-256 to produce the next, but I need a way to work out a hash earlier in the chain via brute-force. How would I set this up with hashcat?

If my problem is unclear, imagine my hasher takes a number, triples it, then applies modulo 50. If I start with 12, I get:
12, 36, 8, 24, 22, 16, 48
I need a way of working out that 8 came before 24, but it doesn't need to be 8 specifically. It can be 108, it will still work fine for what I need. Ideally, it should be able to state what was a few back (that 12 was 4 before 22).

Incremental Mask Attack

I understand how the incremental mask attack works and all.

So when I write a command like this:
-m 0 -a 3 --increment --increment-min 2 --increment-max 5 hash.txt ?l?l?l?l?l

it gives the following trials:
?l?l
?l?l?l
?l?l?l?l
?l?l?l?l?l

However, how about if I want to make increments, and with each increment I want to try numbers from 0000 to 9999.
In other words I want the following trials:

?l?l?d?d?d?d
?l?l?l?d?d?d?d
?l?l?l?l?d?d?d?d
?l?l?l?l?l?d?d?d?d

Which is basically joining a name with a number, but without knowing the length of the name, each name length needs to be joined with the same length of numbers which is 4 numbers.

Thanks in advance.

Windows 10(64) and 3x R9 290

Hello everyone,

Normally I run my config in Ubuntu (According to the sweet manual from this website) with minor issues (no temp).
During a lazy Sunday I thought I'll give Windows 10 a try in combination with oclHashcat. After installation (no errors) I checked my device manger and it showed only 2 of my graphic cards. I used the latest crimson drivers.

Using my bff google i found out that it could be solved by performing a clean install with the latest drivers..
I performed the uninstall procedure (app manager AMD) booted in safe mode and used Guru3d's display driver uninstaller to completely wipeout any AMD existence. Strange enough Guru3d's tool was able to identify my 3 GPU's during the removal procedure. After that I did a clean install but the issue was still there.

Also AMD Settings gives a notice : No AMD Graphics driver is installed, or the AMD driver is not working properly ...

My GPU's are Sapphire Vapor-X R9 290X, (HAWAI).

Anyone the same issue ? is there a limit in the amount for GPU's for Windows 10 ?


thnx Everyone !

hi! I would like to know if I need to clean my wpa handshake capture with aircrack-ng before converting it to hccap? When I use the tool wpaclean in kali-linux It seems to remove important part of 4 ways handshake... Can I just use the file with all the junk traffic and the full handhsake inside it without having problems? I dont want to spend a day to crack a broken handshake. 




https://goo.gl/photos/R6C3uqt3p8UtiKsp6

If I got the 4 way handshake like this picture for the same client I should be ok even with a .cap file not clean?
