Ubuntu Security :: TrueCrypt - Hidden Volume Protection ?

Jan 22, 2010

I installed TrueCrype 6.3a on my 8.1 Ubuntu. Everything went fine until I got to the part where I need to protect my hidden volume from damaged caused by writing to the outer volume (these instructions: [url] ). I can't find the checkbox to "Protect hidden volume from damaged caused by writing to outer volume". The closest thing I can find is an option to "Protect hidden volume when mounting outer volume". Intuitively these don't sound the same to me. There are 2 difference between my setup and the instructions; 1) the instructions appear to be written for Windows and not Linux. 2) I am using a file volume and not a partition volume.

Does anyone know where the option is to protect the hidden volume when writing to the outer volume?

Security :: How Plausibly Deniable Are TrueCrypt Hidden Volumes

Nov 21, 2010

TrueCrypt hidden volume plausible deniability is documented at [URl]deniability but how plausible is it? there is no sign of the hidden volume's existence within the outer volume even if the user is forced to disclose the outer volume password. For this to be plausible the outer volume must be used or the user has no plausible reason for having it.

Quote:

If you mount a TrueCrypt volume within which there is a hidden volume, you may read data stored on the (outer) volume without any risk. However, if you (or the operating system) need to save data to the outer volume, there is a risk that the hidden volume will get damaged (overwritten). To prevent this, you should protect the hidden volume in a way described in this section.

The way described results in the outer volume properties including 'Hidden volume protected: Yes' which discloses the hidden volume's existence. The next section in the documentation has a diagram showing how the hidden volume is created at the top end of the outer volume space. Use of the outer volume must not write in the hidden volume space or the hidden volume will be corrupted. That limits the choice of outer volume file system to one of the FAT series because more sophisticated file systems do write in places across their whole space.How plausible is the choice of a FAT file system on Linux? Even on a dual boot system with the usual Windows versions NTFS is a better choice.

Ubuntu Installation :: Install As A Hidden System Partition With Truecrypt

Oct 7, 2010

Right now I only have Windows 7 64bit installed. I'd like to keep it installed and have a hidden Truecrypt system partition that holds Ubuntu. I've installed Ubuntu once before, but it was a while ago so I don't remember the details. Also, I'm not entirely sure how to work Truecrypt as I've never used it before. Do I install Ubuntu first and then run Truecrypt, if so, how do I deal with the fact that installing Ubuntu involves many partitions. Does Truecrypt recognize this automatically or do I have to somehow encrypt them all?

General :: Dual Boot Windoze+ubuntu W/ Truecrypt+hidden OS?

Jun 19, 2011

I am thinking of installing Ubuntu on my machine, and I may need to still keep windows 7 around for certain games/apps. I want to do a full disk encryption using Truecrypt. As I understand, Truecrypt is compatible with both linux/windows/OSX, and has an option for a "hidden operating system."I want to Install both win7 and ubuntu, with ubuntu as a hidden OS. I have watched tutorials on ..... showing the method for creating a hidden OS for Windows, in this tutorial the second volume was created from the first volume and was effectively a clone of the original OS. Basically what I am asking is---- Is it possible for a hidden volume with a bootable version of Ubuntu Linux to cohabitate on the same drive as windows?If so, are there any howto's/tutorials you could point me to?

General :: Mount Part Of A Dd Image As A Truecrypt Volume

Jul 16, 2011

I have a dd image of a full drive (as a file) that was using Truecrypt system encryption under windows. I want to mount the main partition from that image using Linux's Truecrypt. I am familiar with dd loopback devices and have the partition offset, but I don't know how I can mount it like this because I need to use the truecrypt command.

Is there perhaps some way to create a fake device file for the disk image that I can mount from within Truecrypt?

Ubuntu Security :: Auto Mount The Truecrypt Volume?

Feb 9, 2010

I have a 2nd hard drive that I have encrypted using true crypt. Is it possible to set this up with key files (or some other way) to auto mount when linux boots. I need it in true crypt because there are some work programs I dual boot to use in windows, and need to have access to the drive in XP from time to time, and true crypt can mount there as well. But 90+% of my time is in linux and I would like to have it auto mount through fstab (or whatever way it needs to be). My entire linux setup has been set up with encryption through dm crypt and LUKS (except for /boot). So I would think having a key file stored on the computer and an auto mount fstab would be just as secure as however secure my LUKS setup is. So any way to auto mount a true crypt 2nd drive volume?

Ubuntu Security :: TrueCrypt Volume Is No Longer Bootable

Jul 16, 2010

I installed TrueCrypt in Microsoft Windows XP SP3 (no Linux installations present) and I stopped the TrueCrypt service in the Windows enviroment, and then, I restarted, and all the sudden it seemed the PC can not see the Hard Disk at all at startup, nada... I believe I dismounted it by stopping the TrueCrypt service... So the PC no longer understands there is a TrueCrypt volume in place, and I inserted the TrueCrypt recovery disk, and it can not do any thing, I restored the bootloaders, the true crypt loader, and once I finished this, I press ESC, and it says there are no bootable devices, so nothing. I even decrypted the disk, and it seemed that nothing happened with the restore disk...

Is there any way I can make this partition bootable again? because I have every thing in that partition, every single bit of life... I have used TestDisk under Linux right now, but I am unsure of this, and I also further complicated the boot proccess, and now the PC states at startup about missing partition tables. When I start truecrypt from this Kubuntu live CD, I am unable to see the encrypted hard disk even with root, there is no way to see this hard disk, only can be seen in the TestDisk app. I really I am desperate, at least, if I can not make Windows Boot again, maybe just suck all the files out of the hard disk and put them some where for now, I really need to get back to work, and I cant seem to find a solution...

I know here at Ubuntu forums, some one may have the solution. And I do know for sure all the files on this volume are there because of the TestDisk app, so they are there, they are just not reachable.... (I have posted this problem on a Linux forums instead of a Windows forum because the only way to try to recover the volume is with Linux Kubuntu Live CD

Security :: Truecrypt Volume On Ftp Server Inferior To Sftp?

Feb 24, 2011

If one uses a free ftp account to store private data such as bookmarks, they might prevent any eavesdropping by using ssh for the transfer (ftps), or alternatively sftp.

However, they would still have to trust the ftp hosting provider, because the data is stored unencrypted in the server.

Someone suggested putting all bookmarks in a small truecrypt volume instead and synchronizing this with the ftp server.

Performance issues aside, given that the plaintext only changes a little in each resync (only a bookmark is added usually), is the use of the truecrypt volume introducing a means for an eavesdropper to break the code?

Ubuntu Security :: Securely Delete File In TrueCrypt Volume

Jan 4, 2011

This one being Ubuntu 9.10 (yes, I know I really should upgrade). I keep a number of confidential files in a TrueCrypt container which is a standalone file in my Documents folder. I'd like to delete some of these, but I want to do it as securely as I can, but I believe if I simply hit 'Delete' with the file selected it'll move the file to the Deleted Items folder. This, I assume, means that the file is taken out of the encrypted volume and stored unencrypted in the Deleted folder.

I've been reading a little about the Shred command, and there seems to be some question about whether it works effectively with a journalled file system; and since I have no idea whether I'm using a journalled file system, or how to find out, I'm treating Shred and other over-writing secure deletion tools as ineffective for now.

With this in mind, can anyone advise me how I can protect the file stored in the TrueCrypt volume, and delete it in place, without taking it out of the encrypted area? And, further to that, can anyone tell me whether in fact the file is actually secured while it's in the encrypted volume? For all I know, just opening the volume may result in copies being made somewhere (apart from RAM).

Ubuntu :: Mount TrueCrypt Volume To Recover Macrium Reflect Image?

Feb 28, 2011

I have created a TrueCrypt volume, mounted it in Windows, and created an image file for my OS partition using Macrium Reflect (free version). I made a Rescue CD for Macrium, and the setup works great on unencrypted files, but I have no way to mount the TrueCrypt volume, while booted to the Macruim rescue CD. I have Puppy Linux 4.3.1 on a CD, and can boot to it. I'm a beginner's beginner, however, and I haven't figured out how to install TrueCrypt with Puppy Linux running. Getting the Macrium recovery program to run with the TrueCrypt volume mounted looks even more complicated, and I don't know if it's even possible. I want to be able to recover my laptop from a drive failure, as well as protect my OS from bad programs or malware. Macrium reflect does this job well, because it:

1. is free

2. only writes the used space of the system partition to the image file, and also compresses the data, resulting in a relatively small file. (~ 50 percent of the used space on the OS partition)

3. retains drive alignment for a pre-aligned partition.

However, I wish to keep my backup partitions encrypted to protect my privacy. TrueCrypt does an excellent job of this because it:

1. is free

2. encrypts the OS and all data on the computer.

3. protects all backup data.

I like the fact that Puppy Linux can be loaded into memory, so I only need to boot from removable media to work on my OS partition. I understand there is a portable Ubuntu OS, and perhaps this would be a better platform for my goal? Is there a way to combine Linux on removable media, with Macrium Reflect, and recover an image from a TrueCrypt volume?

Ubuntu Security :: Truecrypt - Remote Mount Volume - Or Send Bash Script Remotely?

Apr 1, 2011

I have an Ubuntu 10.04 machine at home and apache setup on it (files are located in a Truecrypt volume). The reason for the web server being that I wanted to access my files wherever I'm at (i.e. hotel, work, hotspots, etc...). So far, it's worked out great for me seeing as a I can http download my files (or stream media files). However, I am often on a public hotspot and I know it's a matter of time before someone finds the webserver on my computer. I have the machine firewalled and password protected (via .htaccess), but either way I don't want people looking in on my computer.

The problem: I have used Truecrypt for a long time and completely trust using the program to encrypt/unencrypt a volume container to store my files. Usually, I would remote desktop into my computer and mount/unmount the volume when I needed it. However, after time it get's really annoying to do this. So I eventually figured out how to setup a bash script to automatically do this for me (which I put on the usb part of my phone). What I wanted to do was to be able send the bash script to my Ubuntu machine (via ftp from my phone) and have Ubuntu automatically run the script. Is this possible? What programs do I need on Ubuntu?

I was thinking about using something like cron, but that is for scheduled times. I don't really have a set time in which I need my files, it's pretty sporadic depending on how much I travel. Thus the need for being able to remotely mount the volume when I need it.

Summary: I need a way for Ubuntu to read a folder every minute or so to check for bash scripts to run. I want to be able to send the bash script via ftp from my phone, have Ubuntu run the script, then delete itself (so as to not store the password). I already know the script in which to mount the Truecrypt volume and how to send the file via ftp from my phone. It's really a matter of what program to use in Ubuntu to find and run the script.

Debian :: Auto-mounted Truecrypt Partition (keyfile Based) - Can't Add A Keyfile To The Volume Using The GUI

Nov 18, 2010

I have a Truecrypt-encrypted Windows [system] partition, that I want to be opened and mounted automatically (using a keyfile) when I log into Debian, since it is also encrypted and I don't want to type two passphrases. It think this could be done with LUKS. With TC I probably have to go with the CLI, but haven't figured it out yet. And I can't add a keyfile to the volume using the GUI. In order to mount the volume I have to tick the Mount partition using system encryption (preboot authentication) checkbox, or otherwise I get Incorrect password or no TrueCrypt volume found. And same when I try to add a keyfile.

Slackware :: Broadcasted Network (ssid) Is Showing As Hidden (wicd-client)?

Aug 3, 2010

using ndiswrapper for a usbwlan device. Configured and modprobe ndiswrapper confirmed working. When I 'iwlist wlan0 scan'I get cell (wifi network) profiles including my own and several of the neighbours - all showing ssid name and whether key managed or not. When I 'wicd-client' this shows my network as hidden. What makes it even stranger is that wicd-client shows all the neighbours network ssid. Check to see if my router is broadcasting ssid and is without a doubt. I have tried to connect to my router via CLI commands (iwconfig) but unable to connect as is wicd-client - will update with log files on this soon.

Slackware :: GSB Volume Control

I've installed 13.1 and the new GSB.

Newbie slackware user here, I'm having some issues getting keyboard volume control to work properly.I recently fixed my network adapter problem and I managed to get flash player installed despite my minimal knowledge of linux and slackware, but there's yet another small glitch that I can't fix.When I'm logged in as root, keyboard volume controls work perfectly, mute mutes the audio + increases the percentage, - decreases the percentage, etc.However, when I'm logged in as another user and I try to use keyboard volume controls, the bar will pop up in the middle of the screen, but it will be stuck at 0% no matter that I do. (Sound still plays though, it seems that volume is at 100% while the bar in the middle reads 0%).

Slackware :: Mp3blaster Volume Control ?

May 3, 2011

I am using Slackware 13.0 quite out of the box, normally I can change volume for every app using alsamixer. As my laptop is a little bit old working in X uses a lot of resources I have been searching for more and more console based apps. With good results until now.

I started using mp3blaster to listen to music. Great app and all. Only problem I have got is that I have difficulty controlling the volume for it. When in alsamixer I can mute the master channel an control Pcm in small increments so that I can speak about control. When using mp3blaster I have got no control whatsoever. Cant mute the vol channel nor can I control the Pcm2 channel in any way.

My questions are: How do I control the volume in mp3blaster? Why do I have Pcm2 instead of Pcm in mp3blaster? What other info would be needed for anyone to push me in the right direction to solve this problem?

Slackware :: Adding A Volume To A LUKS/LVM Setup?

Mar 21, 2010

I have been following Alien Bob's README_CRYPT.TXT on the install disk and playing around with LUKS and LVM as highlighted in the section Combining LUKS and LVM. I got this working following the examples in the readme however I now wish to add another volume to the volume group. I have got this working and extended the group with an encrypted volume so it's now bigger. I want the two included physical volumes in the volume group (which are both encrypted) to be opened on bootup.

As it is now I am prompted for a password for the first physical volume (the passwords are set to be the same) and that opens and boots the volume. It has a problem with the second PV I have added and doesn't open this. There are errors on boot up about this and pvdisplay give this:

Code:
Couldn't find device with uuid 'JVirxL-lmqH-SUym-3lXG-MnXx-Qjk8-JZRha8'.

As you can see, the first command gives numbers like C841-0655. But for the optical disks (iso9660) it gives them not. Neither does the second one. This number is known as 'Volume serial number' in MS-DOS, and is printed on console with the command 'dir' not only for the HDD partitions but for the optical disks too. how to get an optical disk Volume serial number? Notice that this number is inherent to the media (is a property of the media, under any O.S.).
