RAR crack

July 18, 2017, 7:57 am

Hello,

I'm trying to crack a .rar with hashcat. I extracted the hash with rar2john and deleted the extra characters (possible error location since I guessed).

rar2john provided lines like this:
filename.rar:$RAR3$*0*HASHLIKETEXT1*HASHLIKETEXT2:0::::filename.rar

and I changed to this:

$RAR3$*0*HASHLIKETEXT1*HASHLIKETEXT2

If I start hashcat with -a 3 -m 13000 it complains about the line length.
If I start hashcat with -a 3 -m 12500 it writes about kernel and device initialization, then the OS crashes.

I'm on Win7, tried 3.5.0 and 3.6.0. The NVIdia driver is up-to-date.

If I try to crack an MD5 or WPA it runs smoothly, only RAR cracking has problems.

Could you please help me to decide if the edited hash format causes the crashing or something else?

Thanks,
PMTU

Ps: according to the HashCat wiki, the format of hash is fine.

Please can someone help me? I have the hashcatgui (interface) windows 7.64bits to run with my old nvidia card (8400GS)
When I start the drive I get the following error: this device local size is too small, no devices found / left - I already did everything, I installed nvidia drivers successfully 342.01 but it did not work.

'Budget' rackmount/server rig questions

July 20, 2017, 6:18 am

Hi,

I'm new to the forums, so go easy on me! I'm a big fan of Hashcat and I am looking at taking things to the next level.


I am currently looking to build a password cracking rig that can be used as a demo/training/R&D machine, which means that my requirements are enterprise/business level: 24/7 uptime; multiple users queuing jobs on the server; headless; rackmount available as an option (but can be freestanding for this first demo unit); must play nicely in a server rack with other machines.

Budget is approx £5000 (~$6500), I will be installing all components myself so labour is not a problem.

Currently basing my shopping off of this: http://www.netmux.com/blog/how-to-build-...acking-rig

Looking at 4 x GTX 1070 FE for budget purposes. As this is a demo unit, subsequent builds could use more powerful hardware (1080 etc.) so ideally case/mobo should support this. I can currently source the 1070s at £400 each.

May also be able to fit additional GPUs down the line to increase performance, so would appreciate suggestions for 6-8 GPU cases too.

If I have 4 x GTX 1070 8GB, so 32GB VRAM total, how much RAM do I need? I saw a post saying double your VRAM is a good rule of thumb.

Also, how frugal can I be with the CPU? My use of manipulating wordlists and using rules is fairly limited, but is something I need to start looking at due to the slow speeds of some of the hashes I am cracking. Do I need 2 x Intel Xeon E5-2620 2.4 GHz or can I make do with less? 2 x 1.7GHz Xeon instead?

Apologies if this is all a bit vague, it's early days for this project for me but thought I'd get advice from the experts first! I'm happy to provide some more info about my requirements if necessary!

Thanks Smile

Checkpoint not working in latest version or me being a noob?

July 25, 2017, 5:07 am

Hey everyone,

I'm running the latest development version of Hashcat (previously was running 3.5). One thing I've noticed is I can request checkpoint quit and hashcat just happily keeps going until it's finished or until I force a quit - for example over a time span of 16 hours, requesting a checking point quit at around 10 hour mark, it'll keep going for the last 6...

Recently I threw a huge wordlist at it to the point it would take 4+ days to complete, 12 hours into the sessions I requested a checkpoint quit... 12 more hours later and it still didn't hit a restore point. Restore point sat at 0% the whole time.

Am I missing something obvious here? It always worked for me in the past - at most taking 30 minutes to hit a checkpoint... Only difference was I was using an older GTX 960, now I'm using dual GTX 1080 Ti's and latest development version. If anything I would've thought I'd hit the restore points quicker Sad

P.S.

Using WPA/WPA2 mode with anywhere from 5000 to 30,000 rules.

Epic cracking!

July 25, 2017, 9:33 am

Decades before,an epic hash cracking has took place and very few people know about it.To exploit the weakness of DES encryption,a community of people-known by the software they used to crack the DES algorithm "DRESCHALL",took the world by storm-as they took only 4 months to crack the encryption which consisted of more than 4 quintillion combinations,even with the poor computing power of that time.

They achieved this goal by making use of Internet-by distributing their DRESCHALL client to anybody who is interested and who can afford an Internet connection and spare their valuable computing power.They distributed the key spaces through this client and made cracking faster.They managed to get more than 5000 clients from Canada and got an average speed of 3 TH/s,something which is available with an expense of a single GPU,these days!

Anyway,I just wanted to say that-if such a client is released these days,then even a 20 char long hash can be cracked within minutes,but nobody is interested, what to do?

Support for layered hashes?

July 25, 2017, 7:59 pm

Please excuse me for my inexperience, I truthfully barely have programming experience/knowledge of how the software works (but I greatly appreciate everyone who has developed it!) I know that the basics of password cracking involves brute-forcing/taking plain-texts from a dictionary, hashing them with a specific algorithm, and comparing the resulting hash to the hash you are trying to crack until it yields a match. I have a couple hashes that were hashed with separate algorithms, and trying to crack these to yield another hash will likely take more time than there is stuff in the universe (and then, you still have to crack the other hash again). 

My question is basically if it's possible to bruteforce plaintexts and hash them with multple algorithms before comparing them, it will be slow but not as slow as working the other way around. For example, say you have hashes that you know were first MD5/SHA-1'd and then Bcrypted. This would be a lifesaver if it were possible, consider implementing it hashcat team Smile

CSV, hashes and username...

July 26, 2017, 10:18 am
$
0

hello folks,

I seem to be at a loss and have gone down several rabbit holes.... the "--username" flag, if iv understood correctly, works only if the "hashfile"  where the hashes and username are locaited is written out in the following manner;

username1:hash1
username2:hash2
username3:hash3
username4:hash4
...and so on... correct?

the reason im asking you this is because im having a hard time cracking a list of hashes found in a txt file and then re-combining these hashes to their user name...

when one uses the -o flag the file will only show the cracked hashes, supposedly one is then to compare the specified outfile with the potfile to see which hashses have not been cracked? 

iv tried the --"show" and "--left" flags but I must be using them incorrectly....basically my goat would be that hashcat writes out the list in exactly the same order as the "source" list and eventually omitting the un-cracked hashes..so it would look something like this.....

"hashfile.txt"

username1:hash1
username2:hash2
username3:hash3
username4:hash4
and so on

"outfile"
username1:cracked hash1
username2:hash2
username3:hash3
username4:cracked hash4
and so on....

not sure if any of this makes sense....
while im at it, can hash cat read CSV files as a "hashfile"?

thank you in advance

P.s I can provide the list of username and passwords should you need them....

hashcat stops after about 37 minutes

July 27, 2017, 6:29 am

Hi,

I've got a large number of hashes and for each one I've got a very serious candidate that just need some mask added to get the real password.
So I've made a script that launch hashcat with my candidates (base word + case toggle) against all hashes that share the same "candidate".
The command looks like this:

Code:
./hashcat64.bin -a 6 --increment -m 120 "/foo/bar/hc-tmp/${f}.h" "/foo/bar/hc-tmp/${f}.wl" -1 ?l?u?d ?1?1?1?1?1?1 --potfile-path=/foo/bar/bouclehc.pot --status --status-timer=60 -w 4

Things go smoothly, at least until I reach an increment that brings time above 37 minutes. Strangely, hashcat will just end the session when it reaches about 37-38 minutes. It means it won't finish the last mask (?1?1?1?1?1?1).
Here are two examples:

Code:
Session..........: hashcat
Status...........: Exhausted

Hash.Target......: **********************

Started: Thu Jul 27 13:50:06 2017
Stopped: Thu Jul 27 15:05:15 2017

The script runs in a screen, and is basically a while true loop.

Any idea why hashcat would abort the session after about 37-38 minutes each time?

CUDA?

Does hashcat not actually use CUDA for Nvidia cards now? I'm puzzled over the fact that there's no .cu files on github but there are many .cl files for OpenCL. I keep thinking back to (now outdated) cudaHashcat vs oclHashcat and find myself quite confused over this.

I'm doing a research project for school where I'm making a CUDA md5 cracker, and while programming my own md5 implementation in CUDA, I was thinking of using hashcat's CUDA md5 for good measure to compare against mine/to have a well-implemented version since mine is bound to not be ideal.

Now that I actually look, however, this doesn't seem to be the case. I've already committed to using CUDA specifically for my project so I don't want to just switch to OpenCL. Secondly, I thought OpenCL was noticeably slower on Nvidia cards compared to CUDA due to Nvidia's snail-pace at supporting it? Hasn't it still not gotten OpenCL 2.0 support yet?

Thanks! (I wasn't sure if this belonged in the developer or support forum more, please move if I chose incorrectly)
