How to crack many WPA2 passwords at the same time?

August 5, 2013, 9:39 pm

Hi.

I'm using oclHashcat. I have three passwords for three different WPA2 networks. I was trying to combine them so that oclHashcat can try to crack all of them at the same time, but it doesn't seem to be working. It only picks up the first password in the list and tries to crack it. So it seems that I need to crack each password separately. Is there any way to speed up the cracking of WPA2 passwords and crack them in parallel?

Thanks.

MSCACHEv1 Line-Length Exception when username exceeds 12 Characters

August 6, 2013, 1:55 am

Hi guys,

I'm using oclHashcat-Plus 0.14 hand having trouble when cracking some MSCACHEv1 hashes.

All usernames are converted to lowercase and in the following format:

hash:username(in lowercase)

All hashes with usernames that are 12 characters or less crack fine, using both dictionary and mask attack.

However, I get a Line-Length exception when a hash has a username that is more than 12 characters. For example, I have a file with 3 MSCAHCEv1 hashes. When loading the file into Hashcat, it accepts the 12 character username and cracks it, but rejects the usernames that are 16 and 18 characters long.

Is this a bug or is there something I have not accounted for? I have done a lot of Googling and can't find why this is happening....Unless it is something to do with the salting process, where Hashcat can't handle long usernames.

Any help would be much appreciated.

Medium/large build opinion

I have been asked by my company to design a beefy ass cracking box and could use a second opinion.

I will have a broker box which will dish out the jobs (virtualcl) and a bunch of slaves which should be easily addable in the future.

Broker spec:

Graphics Card 9970 (x3) (When they are released, if they are any good)
Motherboard Gigabyte GA-990FXA-UD7
CPU AMD FX-8150
RAM Corsair CMZ16GX3M2A1866C9 Vengeance
PSU Corsair PSU AX1200

And the workers will just have less ram and a worse CPU as I dont beleive they need it. (currently 1 worker)

To communicate with less latency we are opting towards using infiniband.

Any comments? There is proberly alot wrong with this Wink

Maskprocessor word at position??

Hi is there a way get a mask word by position or range of index.

?u

returns A-Z so instead of

?u -s M

I want to write

?u -s 13

eg

mask[0-10000000]
mask[10000001-20000000]

etc

as far as I can see it is not possible to split a mask via words and still generate all posibilities. or is there?

thank you!

I'm running cudaHashcat-plus64 and am having trouble with a hybrid dictionary/mask approach. I've trolled Google for this type of error to no avail. Here's the problem:

[Image: rockyouIsEmpty_zps6fdbdf5a.jpg]

It shows that the rockyou.txt file HAS words in the stats, but then says it's empty. I can replicate this error with any other dictionary I've tried. Is there a rule that I'm missing here? Thanks in advance!

Is cracking WPA/TKIP faster than WPA2/AES?

Hi.

I was wondering whether brute force cracking of TKIP is faster than cracking AES. I have a few networks here that use WPA/TKIP and I'm wondering whether it makes any sense to switch them to WPA2/AES.
Is it worth it? Will it make cracking more difficult?
I'm asking about oclHashcat specifically, since it seems to be the only one that can use GPU to crack WPA and WPA2.

Thanks.

Looking to get a card in the $150-$225 range that will be good for gaming as well for Hashcat. I don't crack a ton of hashes but crack enough that buying one that is a good choice for both makes it a strong consideration. Thanks for your time.

Compare and contrast Passcape's rules

August 10, 2013, 7:42 pm

As I've mentioned before, I look at the world of file password recovery software, to get ideas of what else is going on out there, with word lists and rules. Those programs don't have 15 character limitations, and make working with multiple word lists easy, for example. They are also all commerical, and typically Russian.

But, trial versions are usually available, and can be broken out by UniExtract, to just look at the help files, word lists, and rules, if one doesn't want to bother with actually installing them.

A relatively new entry to the field are the Office password recovery programs by Passcape Software, at http://www.passcape.com/office_passwords

They have a john-like language, which I haven't compared to hashcat yet, but while most companies either have just a few sample rules, or a few KoreLogic rules, those Passcape's programs have 100,000 lines of rules. D3ad0ne's V2.1 rules distributed with hashcat have 35,000 lines. The more approachable KoreLogic rules for hashcat have around 200,000 lines while the more exotic, like KoreLogicRulesAppendNumbers_or_Specials_PrependLetter.rule alone has over 1,000,000 (one million) lines.

I'm not going to have the time to compare and contrast Passcape's rules to those known for hashcats, for a while, so am asking here, in case anyone else is interested. (E.g., are these simply a subset of KoreLogic's rules or unrelated? Are D3ad0ne's rules in there, without attribution? Or, are they unrelated? Are they any "good"? Etc.)

Hi, I'm new to hashcat but I got hashcat CPU working with HashcatGUI BalndyUK http://www.md5decrypter.co.uk - v0.291 (I've downloaded all the latest files) and now I want to do some GPU instead because it seems to be so much faster than CPU. Well I got like 20-30 dictionaries and with the GUI you can only use two at a time but I figured it out that if you remove the path to the two dictionaries and then write the folder where you have all dictionaries (wordlist/) it will use all of them. This worked fine with hashcat CUP but now when I try with GPU it just gives me a error message "wordlist/: Permission denied". I've copied my wordlist folder and placed it in my hashcat-plus folder.

Currently my linux box (Ubuntu 12.04) is having some major issues. It is crashing regularly, I think it is a hardware issue, (Maybe bad RAM?) but I have also learned to hate Ubuntu.

Another problem I am having is that OclHashcat crashes when I try to use Device #2, and I dont know how to fix that.

Next plan is to nuke the system, take a look at the internals and install a new OS. I am thinking Kali, but need to do more research, the google machine can only tell me so much. So I ask the forum: What OS would work the best with a 2x 7970 HD Radeon setup?

Are there any specific rules for installing the AMD catalyst drivers?

Hi all!

I'm looking to convert an old Server into a password-cracking box for internal benchmarking and compliance checking. For this, I have a HP DL380 G7 with approximately 200GB of available RAM at my disposal. What I'd like to do is throw in a Graphics Card or two. However, I have no idea what to purchase - does anyone have any suggestions? I have £1500-£2000 to throw at it.

I'd love to hear your suggestions!

Hi guys,

I would like to know, if you can help me with some questions:
I want to buy a Tyan B7059F77AV6R-2T, and I will wait for 9970 release and I want to add 8 to this barebone.
Until here no problem, but, I would like to know the impact of memory and processor, on this other tasks:
1) Wordlist - load, generate, sort, merge, etc;
2) Rules - with a0, a1, including the big ones;
3) Hybrid attack - (a6 / a7);
4) Hashcat-utils, maskprocessor, etc.
5) Rainbow Tables - load, generate, index, etc (ok, I know this forum do not have this focus, but, you guys have a lot of hardware expertise, if you can help, ok, if not, ok too Smile ); Here I will use RAID 6 to Load them;
Thank you very much guys for your time and attention.

P.S: sorry for my bad english.

An old veteran wants to access save his information from a samsung galaxy tab. The catch is, he had a stroke & cannot remember the password. I thought it possible to mastercode it, but alas this process wipes out everything, setting the device to factory default settings, he won't go for this at all.

Any suggestions and detailed walkthroughs that may work appreciated.
