Hey guys, I'm here to speak to you today about volatility which is now a memory forensic analysis tool. If you have any questions about installing volatility, head over to the blog I posted before this one that tells you step by step how to install volatility and everything else the dependencies it requires, the base plugin as well as some of the Run malware plugins so today we're just going to show how to crack and so we can grab from a memory dump so these are the windows logon babbblers here the first thing we want to do when we examine memory is, Obtaining the image information of the memory that we are analyzing should indicate that sometimes commands that execute involatility can either be executed very quickly or very slowly depending on several factors mory you have to run, how fast you are and how big the run Dump is that you want to analyze right here. Victim dump DMV is only half the size, so in theory it will run a lot faster than normal systems on de nen can now be run? You know two four six eight those crazy amounts of disk space, so bring that to chemists sometimes you have to wait a bit to collect these things wrong anyway the volatility thinks this memory dump was from a Windows XP Service Pack 332-bit machine and it would be correct, so the criticism, and now we can include that in our commands, so if we use the profile commands that we use duplicate hash marks when disabling this command, it will have a better idea of where to look for certain file structures is supposed to be doing to get our password, we are going to do a great bliss and then you have to give it again, make sure this is correct and if you ever have any questions about ho.
If you know of different types of plugins that you can run there, here is a website you can all go to, so I said we just did Hi Bliss and I'll tell you what it does, and there's a bunch of them here, so if you're ever looking for the help and usage like I had no idea what it is, you can head over to this website and I'll tell you all of the basic plugins that come with volatility as well some of the malware it does what it should be outputting so very useful there are a number of other Memoryforensics memory analysis tools you don't have to use volatility HBGary has two different versions there is a small version which is free and then there is a paper version, which as you can imagine would have a bit more bells and whistles, a bit more analytics tools in itmandiant also has a forensics tool called memorized, so there are a lot of different edene options out there and there is decent documentation on all of them so I'm not really comfortable with volatility bu I would love to try to outsmart Garry's, there is enough documentation to get you on the way to doing your own analysis. I think we're going to take a second pause here so that here you can see what this does is all the places are virtually pulled pulling and physical addresses of beehives that have been found to be in memory so let's pause this here because it generated what we need so here we can see that we have some point files and use your deck files which are unique to each user and then we have the general registry settings or sam security system software, so the only two we need is samand system, only changer instead of five lists that we are going to make strong, this will do is it go through the sam and system bindings and basically all the passwords and that Salt this aunt cuts out aunt LAN LAN uses the pestle files to encrypt the files, so we need two more parameters here, we need the diet, which our system address sse is, and you physically grab the virtual address here again, if you have any questions about which one to grab, go to the website I showed you and it will be able to tell you which one to grab, and we grab the sam and then we need to dump this to a file so we can go so to put it now, what it does is it goes into both registry hives and pulls out the data we need and has it all works for the truck plan, here we have the passwords or the windows system, all residents and reminders, so in the end we can't crack this now, however, we have another free tool called John the Ripper that you simply download from the internet that does this and is very easy to get started. Just give it back man and then give him the file you want to crack and there you go, so one of the reasons NT Land Man is so easy to make is that you can basically only put 14 characters in your password and even if you type more it gets locked after 14 converts them to uppercase, okay so now you have special uppercase and letters to choose from, which could still be a decent amount, but what they do is take these 14 characters and divide them into two seven carrots or pieces and then use the ciphers to encrypt them an old salt that you can find on the internet.
So when you have both tools you can easily deduce what the other is with passwords. Disease You Can See Here So that's one two three four five six seven and then D one two three and then I should have said if you don't count all 14 you just add the remainder to zero so don't worry and then we have administrator 1/2 is a consultant and alas, there you have it if there are a few more I've tried but you know this is a decent amount to get started so this is just an easy one The matter of the show is how easy it is to get things from memory and paste passwords in, and there's a lot more you can do with the membership, you can use it to look for formalware, you can use it to get the rootkit too You can actually get TrueCrypt teams out of it, so there are a lot of things you can do and hopefully in the next few articles I do, I'll show you a few little things you can do with volatility, so up then CheersThanks

Why is Ntuser.dat file in use by another process?
Trying to find out why recently I can't login with my profile. Windows event logs helpfully say that the ntuser.dat file is in use by another process....but which one? The profile presumbably is okay as there isn't a problem logging in with safe boot. I uninstalled the AV software and that didn't help.
