Security :: Forgot LUKS Password - Possible To Crack With Limited Charset?
May 22, 2011I've encrypted my root partition with LUKS and cannot remember my password. My main question is this: is it possible to extract the hash (or key; not sure on the correct terminology here) from the LUKS header and run it through a cracker? The hash type is SHA1 and I can remember the characters I used for the password, just not in the correct order (lots of special characters). That being said, given such a small charset, it should be crackable within a reasonable time, correct? Especially if I used a GPU accelerated cracker. What I don't know how to do is go about getting the hash from the LUKS header. Is any of this possible, or am I SOL? Of course, I have physical access to the system so I can boot it into any utilities I may need to.

View 2 Replies View RelatedUbuntu Security :: Accessing Password Protected Ext3 Files?
Jul 31, 2010I have a drive that originally was used with a Linksys Network Storage Link (NSLU2), then stopped working with it. Now I'm trying to get the files off the drive. When I USB connect the drive to Ubuntu, I can see the files, but I'm unable to open them or copy them. The error message is: "Error Opening File: Permission Denied". I did have permissions set on the NSLU2. So far I'm not able to find a way to get around the permissions issue in Ubuntu.
I have used apps like EASEUS Data Recovery and Recover My Files. It appears that they are finding the files and are able to access them, so I know it can be done. I don't mind spending some $, but these apps are taking a *long* time to run. If I could properly access the files in Ubuntu long enough to copy the files, I think I'd be all set.
Ubuntu Servers :: Postfix Rejecting Password Protected Zip Files?
Mar 25, 2011I recently set up a machine with Ubuntu 10.4 LTS to help to replace an aging VAX mailserver that was the DMZ mailserver for the company I work for. I set up a default install of postfix (via apt-get) to function as a DMZ border device that routes between two internal mailservers based on subdomain aliasing via internal DNS.
The problem is that although I have installed no anti-spam or anti-virus options, mail sent to this machine from any outside source containing a password-protected zip file is being rejected with error:
552 Password protected zip file found inside of the email
At first I'd thought that possibly it was the sending mailserver issuing this error, but after further testing I found that no matter the source, any password protected zip file is immediately rejected. Being as we're in a HIPAA-sensitive environment, this has been relied upon as a backup for people to do one time encrypted file sends via email. The file in question is relatively small, and I do not have any quotas on, and the same test file sent two ways (one encrypted zip and one non-encrypted zip) caused the encrypted zip only to fail.
As stated before, I do not use any type of antivirus or antispam measures, no header or body checks have been put in place, and in the course of trying to troubleshoot this problem, have probably opened my server up more than is strictly wise. I really need to enable this feature as being unable to take encrypted zips puts the entire migration at risk.

Aug 12, 2010I'm trying to crack a password on a pdf document. I have been using pdfcrack from the repositories but when I run the command pdfcrack -f filename I get the error: Encryption not detected (is the document password protected?)
I get the same error if I add the -o or -u option. Does anybody know how to do this? Strangely, I can get into the file just by opening it in foxit in Windows, but when I save it elsewhere it is still password protected, so I need the real password. (Can't print to pdf in foxit in Windows)
Ubuntu Networking :: Using Air-crack To Crack Into Network For Fun?
Mar 9, 2011I'm using air-crack to crack into my network for fun. (It's WPA, NOT wep)
I've acquired a network handshake (I think, do I run
Code:
sudo airodump-ng --channel 11 --bssid 00:00:00:00:00:00 -w data mon0 and capture only four packets for WPA keys?)
After that, I need to run the command aircrack-ng -w wordlist capture_file (where wordlist is your dictionary file, and capture_file is a .cap file with a valid WPA handshake) My wordlist is in /home/steaksauce/Documents/Dictionaries/ and the particular file I want to use as a dictionary is lenth10.txt -- I downloaded a dictionary, and added my own passkey to it so I could have my fun

Sep 8, 2010I am trying to use Ubuntu 10.04 update, but have forgotten the password. If I could get the GRUB prompt, I could use a method I picked up somewhere, but where is the GRUB prompt, which I understand is a bootloader? My installation is single installation on a single partition. I press ESC before the Splash Screen, but just get a square bracket and pressing ESC makes no difference, to the continued boot process, except perhaps make it a little slower. I can use the Desktop and the software I use works fine. There is also something about a 'ring' that requires a password, which I also don't know.
