Sorting many masks by number of combinations?

Hey guys,
As a part of my work we sometimes have hundreds of thousands of hashes, and at the end of our cracking we use a tool that calculates all of the cracked passwords into Masks (i wouldn't mind an alternative to that as well)

However, the next step is, we have anywhere from 100 to 500 masks, and we are looking for a tool that sorts them from lowest possibility (fastest crack) to highest.

Is anyone using something similar and can recommend?

Hi,

Did someone try to run Hashcat from Colab (Jupyter Notebook)? I've tried to followed the following steps https://github.com/semihucann/hash_cracking_with_gpu

However, I get this error :

[Errno 2] No such file or directory: '/root/.ssh/'
/content
cat: id_rsa.pub: No such file or directory


The objective is to run hashcat in a free GPU server. I've tried in both Windows and Ubuntu system.

Hashcat keyspace issue

Hey,
When I use the keyspace command, I run into an issue where a 5/6/7 length mask produce the same output as shown here.

[Image: tJwWXWr.png]


On the keyspace FAQ ( https://hashcat.net/wiki/doku.php?id=fre...a_keyspace ) it reads:

In other words, hashcat's --keyspace is specifically designed to optimize distribution of work, and is not a literal representation of the total possible keyspace for a given attack.

I understand it's not a literal representation, but should the values still be different for 5,6 & 7? How can I fix this? I'm trying to write a program that distributes computing workloads and the keyspace value is important to calculate how much each machine needs to do.

Thanks

BruteShark is a Network Forensic Analysis Tool (NFAT) that performs deep processing and inspection of network traffic (mainly PCAP files). It includes: password extracting, building a network map, reconstruct TCP sessions, extract hashes of encrypted passwords and even convert them to a Hashcat format in order to perform an offline Brute Force attack.

Doing research to build a rig, would like opinions

May 2, 2020, 4:36 pm

So, this is the specs I was thinking about doing it.

frame: Veddha V3C 6-GPU Mining Case 36.99
mobo:  ASUS WS Z390 PRO LGA 1151 (300 series) 387.99
gpu:  GTX 1080 TI 1x (for now) - used so prices vary
ram:  G.SKILL TridentZ RGB Series 32GB (2 x 16GB) DDR4 3200 - 159.99
cpu:  Intel Core i5-9600K LGA 1151 (300 series) - 199.79
ssd:  Kingston A400 2.5" 240GB (OS ssd) - 39.99
psu:  CORSAIR HX Series HX1200 80 plus platinum - 249.99
total: ~1074 without GPU

possible additional SSD to store wordlist, would it be quicker to cache if they were on separate SSD from each other, or just buy a 1TB separate SSD and just throw wordlists on there?

I have been looking at how people build their mining rig and base off of that, thats the reason for the frame/case I chose, possible additional GPU if I want to.

I noticed majority of the mining rig are using.. low specs.. celeron cpu with 4gb of ram, I didn't like that, and went with 32gb (possibly go up to 64gb if its worth it) and i5 cpu, or is it overkill?

My plan is to buy used 1080ti and have a max of 4 GPU, maybe 6 GPU over time, not all at once, what I also didn't like is those risers they used, using usb 3.0, it just seems like another performance loss, maybe im wrong but would it be better to be ribbon extension cables for pcie x16 3.0, like this one here?

https://www.amazon.com/Thermaltake-Gamin...050&sr=8-4

But what I am worried about is electricity, This won't be running 24/7 idle, only when its "working" and turned off after that, I don't want my roommate having a heart attack why the electric bill is hundreds more than usual, or am I overreacting on that, I guess I wouldn't know unless I have one of those plugs that gives me average of how much electrcity I am using.

Would a 1200 psu be fine to run four 1080 TI, or what psu setup would I want if I end up going to 6 gpu, but of course if I do that and want to keep a beefy cpu it seems my only option is i7 on lga 2011 socket, along with ram

Dusted off old gaming laptop

Hello all.

I just found my old MSI gaming laptop (GX660R) and installed the latest version of The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) 2.0 onto it, and hoped I can put it to some good use again.

I remember the good old days when I ran BT on it and used to crack hashes with my Ati Mobility Radeon HD 5870. Trust me, it's a dinosaur these days but still good compared to run CPU cracking tools.

Now to my problem, it seems that the card is no longer supported obviously, and I have had a hard time finding anything, drivers vice, that works.

Here is some dumps from the system:

$ hashcat -b
hashcat (v5.1.0) starting in benchmark mode...

Benchmarking uses hand-optimized kernel code by default.
You can use it in your cracking session by setting the -O option.
Note: Using optimized kernel code limits the maximum supported password length.
To disable the optimized kernel code in benchmark mode, use the -w option.

* Device #1: Not a native Intel OpenCL runtime. Expect massive speed loss.
            You can use --force to override, but do not report related errors.
No devices found/left.

So if it isn't obvious already. I want this old kitty to rev those fans back to maximum speed for hours again. My problem is that I lack advanced experience solving these kinds of issues without taking down the whole OS a couple of times, reinstalling, etc, and to be completely honest also lack proper knowledge.

So I know it has been running before, and I would like it to be able to run again. Is there anyone on this forum willing to help me resurrect this laptop to its former glory? Help me sort this problems out?

I would appreciate it greatly! Thanks!

Author wrote, the generated hash:
"The hash will look like this string: {X-PBKDF2}HMACSHA1:AAAD6A:SEvDOw==:1rmVDmR6OgwPEYV5CiwUeYnd+OE="

Can you explain, what the 2nd field (AAAD6A) is for?
Can iteration be determined from this format?

Revised build advice.

I originally made a thread, then deleted it, and revised my build, and would like input please.

Here is the specs:
frame: veddha 6 gpu mining open frame - 36.99
cpu:    AMD threadripper 1900x cooler - noctua nh-u12s 266.95
mobo: asrock x399 gaming 6 - 239.99
ram:  G.skill ripjaws V 32gb (will be upgraded as I get more GPU) - 138.99
ssd: sandisk 240gb - 44.99
GPU: used GTX 1080 TI from ebay or where ever. - varies
PSU: EVGA supernova 1600w 80+ platinum - 419.99

os: ubuntu/debian or something of the sort for CLI.

With the frame I am using I am guessing it won't matter about getting Founders edition considering the frame I am buying is open frame, and has 5x 120mm fans going across the front of GPU, right?

I came across a post someone saying even if I have 64 lanes, and other resources use the lanes, best I can get is having two cards be 16x and two cards being 8x, is that depending on the build or no matter what, thats best you're going to get?

From my understanding if I run 4x GTX 1080 TI 11gb I will need at least 44gb of ram for that alone(1gb ram per 1gb nvram), and then I also need to consider ram space for wordlist, I was thinking of topping it at 64gb when I get my third card, and 64gb should be enough for all four, or should I consider going beyond 64gb?

could I be wrong to assume that gpu risers that use those 3.0 usb, will hinder performance?
I was thinking of going with these instead, or will it not matter?

Help implementing FNV1 for a3 mode

May 4, 2020, 3:07 am

Hello everyone,

I have successfully implemented a very simple Hashcat module for FNV1 but only for the a0 mode. Because FNV1 is working with bytes (u8) and not u32 I'm having trouble developing the a3 mode.

I have seen the new Hashcat development guide published recently. I think the example of a simple implementation with comments (I've put a bunch of them) could be a nice addition to the guide.

Is anyone interested in working on FNV1 for the a3 mode ? Or does anyone have another idea for a simple hash that I could implement, document and possibly publish as a guide ?

I will post a similar message on the Freenode IRC as well.

Cheers,

Tachsah

Do the version 5.1 support iterations or custom combination of current hashes?

May 5, 2020, 12:15 am
$
0

Now ,I want to crack one hash computed by serveral iterations of HMAC-SHA512.

For example, 
In the first round, hmac-sha512(salt,password) produces h1.
And in the later rounds, the salt is constant and the password is the result of previous round.

I notice the john the ripper support the feature. However, In the implement of HMAC-SHA512 of the jtr, the password is key. and in the hash I want to crack  the salt is key. It also can't work.

So I want to know if the hashcat 5.1 support this feature.
if not, will hashcat support it in the future?
can changing the kernel files solve it?(I saw this method in other post)
