uninstall catalyst [resolved]

So I have a perfectly working catalyst 13.x/oclhashcat1.01 installation.
But I can't update because I can't remove catalyst 13.

Code:
user@brutev2:~$ sudo aticonfig --uninstall
AMD Catalyst(TM) Proprietary Driver Uninstall is corrupt.  Uninstall script 'fglrx-uninstall.sh' is missing.

just to be sure:
Code:
sudo sh /usr/share/ati/amd-uninstall.sh
AMD Catalyst(TM) Proprietary Driver Uninstall is corrupt.  Uninstall script 'fglrx-uninstall.sh' is missing.

and dpkg -l | grep fglrx comes back blank.

can someone point me to instructions for removing it manually? or will --force work well enough?

hi the command iv used is
c/hc64/stp/stp64.exe --pw-min=8 --pw-max=8 hchcstat ?l?l?l?l?l?l?l?l | hc64/hc4.exe -n40 -m2500 mine.hccap

Its ran fine for 16 hrs with temps under 75 and hash rate 280 kh/s.
suddenly now the progress keeps going up with 0 rejected or skippe. The weird thing is the hashrate and gpu`s are at 0kh/s and 1% usage from 91%util and 74*c.
Any ideas please would be apreciated.

I'm new to ALL this

Hello! First of all, I'm really sorry if i'm not allowed to post this kind of Threads, or if this is not the correct section to do it.
The thing is that i'm completely new to Hashcat/oclHashcat, or any password cracker in general. I have no idea what a Hash, or Mask is so I guess that i'm completely lost. I have decent understanding and knowledge of programmaing... I dont know if that helps.
I've really been trying to find an easy/simple video tutorial, or written tutorial, and trying to understand what a Hash is, but i'm not getting much from it. I would REALLY apreciate if you could give me an easy tutorial/guide.
English is not my first language, sorry if I expressed myself poorly.

I'm just asking for some tutorials/guides so I can study from that, or any advices related to where can I get started...

BTW: I was trying to crack the password of an account a I've had for a long time in a game, but I forgot the password. It really doesn't have a decent security, I don't know if that helps. Well, will it be possible for me to recover my password? The game doesn't offer any other way to do it.

Thanks for the attention guys!

boot up hangs after catalyst update

Hi Guys,

Can't seem to figure this one out. I have 4x HD 5970 in a HAF tower. Everything was working fine with old catalyst driver (have not updated since November 2013) and all 8 GPUs were recognized by the system.

Since latest oclhashcat required newer driver, I've uninstalled the old using the scrip from /usr/share/ati, reboot, installed catalyst 14.4, ran amdconfig --initial -f --adapter=all post installation. However now the system hangs during boot with a blank purple ish background.

If I do not execute amdconfig --initial -f --adapter=all system boots up fine but only 1 HD5970 is recognized.

Has anyone see this before? Any suggestions?

Hi guys. Can anyone help me please. From the start in this video tutorial, the guy explains himself fairly well how to use hashcat in CMD, but here's the point in the tutorial where I get lost. Around 8:27

Where do I copy and paste the hash from to put in the txt file document named hash?

My target is truecrypt, so I'd be looking on this page here then fill in the numbers corresponding to truecrypt?

https://hashcat.net/wiki/doku.php?id=oclhashcat

62XY = TrueCrypt 5.0+

How or where do I type in the cmd? Can someone help fill in the missing blanks, please?

ERROR: clGetDeviceIDs()

Hi,
I have 2 GPUs ATI Radeon R9 290Xs.
Code:
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Hawaii XT [Radeon HD 8970]
02:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Hawaii XT [Radeon HD 8970]
I'm using oclHashcat 1.21 and when I run it from the console, oclHashcat runs fine but when I run via SSH I get the following error:
Code:
$ ./oclHashcat64.bin -m 500 -a 3 -b
oclHashcat v1.21 starting in benchmark-mode

ERROR: clGetDeviceIDs() -1

$ echo $DISPLAY
localhost:10.0
The X11 Forwarding seems to be working ok. I can get the remote X11 apps to show up on my machine. I'm running oclHashcat on the remote gnome-terminal app. When I run the same command via console it works fine.

Any idea what I can do to fix this? So I can access oclHashcat via SSH?

Thanks!

Custom solution for MD5?

August 6, 2014, 9:10 am
$
0

Hey everyone, wasn't sure where to post this but i figured i'd give it a shot. I'm trying to solve for some MD5 Hashes but not in the typical
sense.

I have an equation where i need to solve for a variable, it goes sort of like this:

StringaStringbStringc = Stringd(md5 hash of concatenation of Stringa+Stringb+Stringc)


We know the values of Stringa, Stringc, Stringd. We try to solve for Stringb

So with example values substituted we have,

1234(UNKNOWN_STRING_MD5_UPPERCASE)5678 = 4bd16ac7d6af4a922109bfffb0f6564d

Stringa=1234
Stringb=(UNKNOWN_STRING_MD5_UPPERCASE), which is the uppercase MD5 digest of a lowercase alphanumeric string, 8char max.
Stringc=5678
Stringd=4bd16ac7d6af4a922109bfffb0f6564d


We need to solve for Stringb, we know that Stringb is the (UPPERCASE)md5 result of a lowercase alphanumeric string, that has an 8 character limit.

We know that Stringd(4bd16ac7d6af4a922109bfffb0f6564d) is the md5 result of the concatenation of Stringa+Stringb+Stringc.

So in this case, solving for Stringb eventually provides us with the uppercase MD5 Value of "AE2B1FCA515949E5D54FB22B8ED95575", which is "testing" in plaintext, and it fits in the equation

So, we have:

Stringa=1234
Stringb=AE2B1FCA515949E5D54FB22B8ED95575
Stringc=5678
Stringd=4bd16ac7d6af4a922109bfffb0f6564d



MD5(1234AE2B1FCA515949E5D54FB22B8ED955755678) = 4bd16ac7d6af4a922109bfffb0f6564d


What i'm looking to do is have a script created that solves for stringb in this exact format.


Stringa, Stringc, Stringd would all be known constants, and it would try to solve for stringb in the way i outlined above. Obviously i am paying for someones time and effort in creating an efficient script / addon to do just this.

I just purchased an 8 GPU 4U rack mount server but I am up in the air as to what cards to run. If I am correct the best card for the cost vs. performance is the R9 290X am I correct? Or should I use 7990s?

Any suggestions?

Cards not cracking at the same speed

I have three R9 290 in a single server and I have noticed lately that there are huge differences in the speed at which the cards are cracking passwords (see attachments).

I am running oclHashcat in Windows and I was wondering if perhaps my AMD Overdrive settings were not optimal (all cards have the same settings)?

Thanks for your help!

Noob question on command line cudahashcat64

I'm trying to define a command line to crack the NTML hashes of Windows7
I've created a few to test my "script" They are relatively easy and should take seconds to crack, with no results.

cudaHashcat64.exe -t 32 -m 1000 -a 3 ntlm.hash ?a?a?a?a?a?a?a -i --increment-min=7 --increment-max=7 -o=hashresults.txt
pause

When I created the test hashes I went to "http://www.tobtu.com/lmntlm.php" set them up with upper & lower case along with numbers. I will however need the script to look at special characters as well in the future, hence the ?a. Also future consideration the min password length will be 8 char.

HD7950 multi-GPU issues

August 9, 2014, 6:08 am
$

Hi all, I have been having some problems getting 2x7950's working with oclHashcat using Debian Wheezy. I have installed a stock Debian wheezy with OpenCL headers and the "amd-catalyst-14-4-rev2-linux-x86-x86-64-may6.zip" drivers, this shows two GPU's present with amdconfig and I used aticonfig to set both cards for use with X11. The devices appear to function fine, when I run oclHashcat (without any AMD SDK installed) it can see only ONE GPU card and will benchmark and crack hashes on a single 7950 just fine. I added the AMD SDK "AMD-APP-SDK-v2.9-lnx64.tgz" to the host (as I also wish to use John the Ripper with GPU support) and then when I run oclHashcat, two devices are detected but complains the incorrect or non-official drivers are installed, when I use --force I receive the error "clBuildError() -11" (or similar, I forget the exact API call as the box is nuked again). I read that perhaps this could be due to the versions of driver installed and so have tried (without success) to rotate the drivers to alternative versions and with AMD SDK 2.7 through to 2.9, all giving similar results or breaking the box horrifically (requiring a rebuild.)

Has anyone any tips for the precise software driver version I should be using or why I am experiencing this error? Both GPU's seem fine under amdconfig and I can use a single GPU pre-AMD SDK install but I could really use both functioning as I have a pile of hashes I would like to crack.

Kind Regards,
Hacker Fantastic

So during brutforce 8 to 12 char will be tested in same time.
