password cracking

Interesting research from using the parallel processing capacity of graphics cards to speed up the password cracking process. Pretty inventive thinking as graphics cards get more and more powerful and they are created to do massive agree tasks for all the latest and greatest games why not apply it to password cracking! A technique for cracking computer passwords using inexpensive off-the-shelf computer graphics hardware is causing a displace in the computer security community. Elcomsoft a software company based in Moscow. Russia has filed a US patent for the technique. It takes advantage of the “massively parallel processing” capabilities of a graphics processing unit (GPU) - the processor normally used to produce realistic graphics for video games. Using an $800 graphics card from nVidia called the GeForce 8800 Ultra. Elcomsoft increased the speed of its password cracking by a factor of 25 according to the company’s CEO. Vladimir Katalov. A top end graphics cards makes your cracking 25 times faster now that’s a pretty impressive increase if you ask me. Worth investing for regular pen-testers who do a lot of cracking to test password strength. The toughest passwords including those used to log in to a Windows Vista computer would normally act months of continuous computer processing time to change using a computer’s central processing unit (CPU). By harnessing a $150 GPU - less powerful than the nVidia 8800 card - Elcomsoft says they can cracked in just three to five days. Less complex passwords can be retrieved in minutes rather than hours or days. Elcomsoft says it took three months to develop code to take advantage of a GPU and the company plans to introduce the feature into some of its password cracking products over time. I’ll be watching where this goes and will be interested to see if any open source tools come out capitalise on the GPU capability. This is very genius. Why didn’t I think of this? After all password cracking comes down to raw computing cater. I’d like to see the first password crackers to combine this technique. As soon as I construe this it reminded me of - They make PCI boards with 4096 parallel processors running at 300MHz supported with a small amount of RAM. I considered these for password cracking as the boards are (relatively) cheap. Unfortunately the developers pack was (and maybe still is) rather expensive. Read this a couple of weeks ago about this GPU cracking…My fav quote is from John Callas from Columbia University(NYC)…”Once you’ve shown you can do cryptography with a graphics card Latest News about graphics separate doing cryptanalysis with a graphics card is really the same sort of thing,” he reasoned.“Once you’ve heard you can make a frozen daiquiri with a blender it’s like saying the frozen Pina Colada is a new invention,” he analogized. “It’s not really a new invention. It’s changing the ingredients and realizing the blender works that way.” Anyway its still interesting nonetheless and whether or not its patentable. I definitely think this is going to be to be useful. Very old news Folding@home have being running code on GPU’s(ATI X1900,PS3’s Cell processor) since 2006. And there’s a paper from theIEEE called ‘FDTD calculations using graphical processing units’ dated April 2005. Anyway rainbow tables are still the quickest and most cost effective way to change hashes. P. S. It would be better use of your GPU to generate said tables. If anyone wants more info on this Google ‘GPGPU’ or ‘General-Purpose Computation Using Graphics Hardware’ so does this mean we need to be concerned about botnets exploiting graphics cards on sweet gamer pc setups? just evaluate how powerful a distributed cracker would be passwords would be jacked in seconds! scary cool development. People with really fancy gaming rigs are usually fairly sensible and thus immune to being botnetted… at least. I hope they are. I cant wait for the GPU manufacturers to come up with something to “stop” this… Like -Foo- and -James- already mention age old news. Both Nvidia and Ati released their GPU toolkits quite a while ago. Ofcourse I would be very interested to see the first p0wn3d SLI setup. It’s my guess however that PS3 owners ordain be a more suitable target heaps of computing power networked by default and quite a user base. All we have to do is wait for a real world PS3 exploit to turn them in to botnet drones. That could be tasty… console owners suck at security mostly… Case in inform is my housemate’s Wii… He runs it on our wireless network the security settings on the switch for which are all off to let me play… But the Wii itself looks to have no firewall or protection from malware at all… admittedly neither does it have much proccessing power but then botnets dont need all that much power in each component if they have access to enough units so… I think i’ll be watching network traffic more closely for a while now i’ve said this… Have you seen any news out there about malware being crafted specifically for the Wii (or PS3 for that matter)? Not personally knowing the base OS/kernel for these consoles. I wonder what kinds of “proof-of-concept” examples are out there for these. @Sir HenryNo I have not heard of that. Sounds very interesting. I remember when cellphone viruses were a big deal. I guess the hackers have moved on. What would be the point of hacking a Wii or PS3 aside for pissing a lot of people off? I could see maybe with an XBox live account you could use the credit separate on the account to buy a lot of games but other than that I still don’t see a reason for it. re: taking over consoles - if that were done they could be used to do a lot of processing; the PS3s for example are utilised on a sort of passive sleep mode (unused clock cycles & when not in use) to do the folding@home mentioned. This topic area is bound to get all the more interesting as the graphics cards continue to get more powerful - there’s now triple SLI and DDR3 RAM on them is more and more common. Also the high-end gaming PC is becoming more common too with folks buying them off the shelf! So not as security-conscious as may be thought. Add in ever growing interest in bit-torrent and there’s a huge potential for those botnets to operate on. (not entirely on-topic but of arouse - the gaming card Killer NIC is a linux-running network card that does packet prioritising for gaming and enables things like down/up loading all without calling on the CPU; it was UDP-only on launch but it comes with a kit - I’m not sure how much tweaking etc has been achieved as yet but it certainly caught my eye anyway when I read about it.)

Disclaimer: Do not try this on unauthorized systems. If you lose a Windows password or you buy a system that has an OS on it but you don't know the password what are you to do? The best thing to do would be to throw in a Linux CD format the control and install the Distro. But what if you want to boot to the system and see what's on there and get data off? Well we have quite a few options. I'm going to cover two of them. I'll start with ophcrack. "Ophcrack is a Windows password cracker based on rainbow tables. It is a very efficient implementation of rainbow tables done by the inventors of the method. It comes with a GTK+ Graphical User Interface and runs on Windows. Mac OS X (Intel CPU) as well as on Linux."We're going to use ophcrack live cd which is a stripped down version of slax using fluxbox with ophcrack running on top. The cd can be downloaded here. Once you burn the ISO you just boot the cd and it goes right to work. In my case because I'm running on a 64 bit system. I had to pass the noapic option on bootup. I setup a couple different accounts to test the ability of the software. With the first account. I used a simple password "coldplay". With the second account I used a simple but randomly generated password "wzgqptjb". For the third account. I generated a 12 character random password with symbols and special characters. "c?4"e9n^bA!t". The last account had the same criteria. "\O0//|?3>q)h". The results were somewhat predictable object for the last two accounts. Within 2 minutes the first two passwords were revealed in the window. I figured the other two may take a while so I went and played guitar hero for a while coming back occasionally to check on them. After about 30 minutes it had completed it's cycle but told me that the last two passwords weren't found. For plain character passwords it doesn't seem to be whether it's randomly generated or just a word. They were discovered simultaneously. But as far as the second two go. I guess 12 random special characters is enough to stump ophcrack. I figured it would just brute force it if nothing else. But that wasn't the case. So with that program. I was halfway successful. I might have gotten lucky and gained administrative priviledges with those 2 accounts but with passwords like that they're most likely regular user accounts. On to the next program. This is my favorite one because it's around 3MB for the entire image and instead of going through a crack process it completely blanks the windows password in very little measure. It's called "Offline NT Password & Registry Editor" and can be downloaded here. Just transfer the image unzip it and burn to cd. Cd's are cheap so don't complain about wasting a cd for 3MB of space. Once you boot to it it will try and autodetect everything. Unless you lay Windows in funky directories all defaults will do the trick. The menu is very straightforward and easy to use. I selected the admin account (the more difficult password) which is the default. Then I used the command * to blank the password. Then I typed in the name of the other account and blanked it as well. This took around 3 minutes total including boot time. Then I exited making sure to save my changes. Once I rebooted into windows. I logged into my accounts with NO password. Everything worked perfectly and I had admin privilges. With this program it's really irrelevant how long your password is. It just blanks it with a quick registry edit. Why wait for password cracking software when you have this? Consider your system owned if someone has physical access to it. It's a great precaution to use secure passwords on your systems but security is relative and there's always a way around things. You could of course enable a bios password to bump the security up a notch. Be smart and never think that your system is impenetrable especially if you use Microsoft's products. If you're interested in recovering passwords in linux here's a great article on ubuntology.... One last thing..... I wanna furnish a big HELL YEAH to Wayne over at. His site is great and it's only getting better as time goes on! "You could of course enable a bios password to bump the security up a notch."That really doesn't solve anything as there are two ways around it: (1) you can usually disable or clear the password with a jumper setting on the motherboard; (2) if no jumper then you can certainly do it by resetting the BIOS - all you have to do is remove the batter. The point? Once physical security is compromised nothing will stop someone from getting at the data. If you're that concerned about it then it should be in a secure facility with armed guards video cameras etc. In the inspect of laptops or other systems that travel then use full hard drive encryption - but once physical security is compromised the thieves have all the time they want to break it hopefully it will take them longer to break than it will for you to (a) cognise it and (b) do something about it to resolve the issue.
