Ubuntu Security :: Black Hats - 105GB FAT16 Hidden Partition On Hard Drive
Mar 31, 2010
Since August of 2009 I have been under attack by corporate Black Hats. I found a 105GB FAT16 Hidden partition on my hard drive. Seventy four percent full (78GB). What led me to this was the fact that I couldn't help but notice that my Internet connection was a revolving door that never stopped spinning. So I went looking for why.
I removed the hidden flag, and patched the partition, but couldn't open that thing no matter what I did. I tried for a month. The attacks started as soon as I stopped these guys from accessing that data. At this point we are 9 months into 24/7 attacks. I have interviewed with the FBI, and local law enforcement, but they are intent on making me out to be a conspiracy nut. I am not at all. All they wanted to do is quiz me on my computer skills. If I managed to draw the attention of a corporate security group they killed it.
I am a US Navy trained Electronics Technician. 58 years old with ECM experience. I have been doing both bench, and field service on all manner of electronics for 40 years. My last job was supporting field engineers, and technicians for Samsung Electronics of America. The attacks have spread to my mother, and best friend. My phones are bugged internally at the phone company, and my modem has had its firmware altered to call them. They run around inside my ISP like they own the place.

I decided to swap my existing small hard drive for a bigger one which went well. Then I formatted the old drive using a windows vista machine before putting it on my spares shelf. To my amazement after formatting my 20GB hard drive had become an 8GB hard drive. I fear the worst but remember that Ubuntu put a large swap file on the drive and wonder if Vista has just ignored the system partition. I tried attaching it to my Ubuntu laptop which reports a healthy 8GB hard drive even after formatting again. I don't know enough about Ubuntu to try repartitioning it in that so I tried DSKCHK in windows which reported a healthy 8 GB hard drive. Is all hope lost or is it a "hidden" partition which might be recovered under Ubuntu? If so, how?

I've been running Linux for a year on our family computers (one desktop, one laptop and two netbooks). I've run into a problem with the encrypted ext4 partition (270GB) on a LaCie external hard drive which also has a NTFS partition (50GB) which is not encrypted . First two times I tried using the encrypted ext4 partition (from two different computers) it worked fine but now I can't access it at all. I can still access the NTFS partition.Encrypted external hard drive partition will unlock but won't mount (or unmount). The computer says "Opening 320GB Hard Disk" but after a minute says, "Unable to mount location. DBus error org.freedesktop.DBus.Error.NoReply"Disk utility (GUI for gparted I believe) states that the encrypted partition (/dev/sdb1) is unlocked and the underlying partition (/dev/dm-0) is not mounted but it has a "busy circle sign" on it that will not turn off. The NTFS partition on the same drive mounts and accesses normally.
But if I try to unmount the NTFS partition, it says: "Unable to stop drive. One or more partitions are busy on /dev/sdb"If I try to shut down the computer, it is unable to shut down because (I assume) it can't shut down that drive either. So I have to just turn off the computer.fdisk states that /dev/dm-0 doesn't have a valid partition table [full output attached]fsck suggests: "Filesystem mounted or opened exclusively by another program?"ps axuf shows some processes running on /dev/dm-0 but killinghem doesn't release the drive either. [full output attached]I checked /etc/blkid.tab (suggested in one vaguely related thread) and there's no actual file only a broken link pointing to /dev/.blkid.tab (which doesn't exist). I tried deleting this link and rebooting but that didn't change anything.when I finally gave up my data as lost, I tried to format the partition (using Disk Utility) and it refused saying, "One or more block devices are holding /dev/sdb"

My parents bought a new hard drive for a laptop that I've owned for several years. It's much larger than the current one, so I plan on splitting it up to dual boot it with Ubuntu.I have no problem with partitioning a drive (I always keep a LiveCD handy), but my question is this: how can I go about moving the existing partition to the new drive? This is a laptop, so I can't simply plug the new drive into another slot.
Also, even if I manage to move it, will Windows still work on the new drive in a larger partition? I've had this laptop for quite a while, and I've lost the recovery discs that came with it a long time ago. I also have a lot of software without CDs to reinstall them with. This makes not reinstalling Windows a high priority.

I am trying to move a whole bunch of files from one partition on one hard drive to the same partition on another hard drive. Can I mount the same partition (same name, different drives, i.e. /data on /dev/hda1 and /data on /dev/hdb1)and copy those files? Shutdown the server, take out /dev/hda1 and boot up with the new drive and it's /data contents.

I have a rather strange need to keep a FAT16 partition to run a very old DOS app (diving computer interface)which talks directly to the hardware and therefore refuses to run under anything that a pure DOS (I can run it under "qemu" but the interface doesn't work this way).So, side by side with my SAS RAID array sits an old SCSI-2 disk with one FAT16 and few HPFS partitions, mirrored from my old (but still working) OS/2+DOS PC.

I installed Redhat Enterprise 3 on one of my servers. In my haste I didn't properly partition both Hard Drives and only properly partitioned one of them. Thus now I have
/dev/sdb1 478711768 137858256 316536328 31% /
/dev/sda1 101089 15346 80524 17% /boot
Where /dev/sda1 is actually a 80 GB hard drive. Is there anyway I can safely and easily repartition the unpartitioned space without causing a huge mess? I have a very important Oracle database on /dev/sdb1 and thus I want to be able to back it up on the second disk. I can create a partition on that drive?

i installed Fedora 12 on an external hard drive. Everything went fine with the installation and it was working perfectly until i tried to install my video card drivers. I have done this many times before and it has worked. I have an ATI card. Anyway after installing the driver i rebooted and now when it starts it show the loading bar on the bottom but then nothing happens its just a black screen!. The worst part is that when i go into windows and my external is plugged in windows wont read it and i have very valuable data on it. I go into disk management and it shows up but windows says that its empty. which is obviously not true because Fedora starts to boot. I really just want Fedora off my external and for windows to read my external with all the files still on it. Is there a way to get by that blank screen?

I have an existing install of 10.4 on a 320 GB hard drive without home in it's own partition. I have a new 500GB hard drive that I want to install 10.10 on. After installing 10.10 and making /Home on it's own partition can I copy the entire old home folder including the hidden files to the new home partition on the new hard drive so that all of my programs and files are saved. I don't have enough room left on the old hard drive to create and copy home to a new partition. Am I going about this the right way or do I need to rethink and do some kind of backup restore on the new hard drive or some other way. I am trying to accomplish this so that in the future I can install a clean copy of Ubuntu when they are released without losing my current settings and files. I started out with 7.10 but my learning curve is slow.

I have just put a new hard drive into my laptop (new drive is dev/sdb) I have formatted the new drive as an ext3 system. On my old hard drive I'm dual booting windows 7 and ubuntu, so my old drive (dev/sda) has several partitions. I am trying to copy ubuntu which is on dev/sda3 (which is itself an "extended" file system composed of sda5 "ext3" and sda6 "linux swap") to dev/sdb. Once copied i intend for the new drive to be an exclusive ubuntu drive and the old drive an exclusive windows 7 drive (by getting rid of dev/sda3 whose content should now be on dev/sdb.) Ubuntu was installed on the old hard drive after windows 7.
I understand the boot loader will be affected although I'm unsure how. I have Gparted installed. I have looked at the man page for the dd command although I don't know how it would work in my particular example. I have also looked at Clonezilla although I don't know if this is appropriate for what I want to do. I have read a few similar threads although I found some of them difficult to follow.

I want to copy my ubuntu install to a bigger hard drive, and am not quite sure what to do. According to my google searches, I need to run ubuntu from a live cd, then in a partitioning program copy the ubuntu partition to the new one, then resize it. Is that all? Do I need a linuxswap partition on the new hard drive? I have been using kde partition manager to arrange my new partitions. On one hard drive I have the partition I want to install ubuntu on(what type should this be? ext4?) and a partition to share between ubuntu and windows, and then will use my old ubuntu partition for installing windows xp.

So what I want to do is encrypt my entire hard drive, but heres the thing.
I dual boot Ubuntu and windows 7, but I am afraid that if I use truecrypt to do the encrypting that it will wipe GRUB and not allow me to boot into any OS, is that a possibility and is there a way around it?

I'm trying to install Ubuntu 9.04 on an HP Compaq dc5000 uT with Windows XP Pro. service pack 3. Downloaded the ISO file and burned a CD with Infra Recorder. The demonstration version works ok as far as I can tell, this is my first try at using any form of Linux. If I can get Ubuntu to work I plan to get rid of Windows completely. I'm stuck at step 4 of the install process, all options in the partition window are dimmed, nothing is clickable.

I made a new partition on my hard drive, and installed Windows XP on it. However, because of space shortage on the disc (didn't bring my external HDD's with me) I could not "afford" to make the partition bigger than about 7GB. Turns out that's not quite enough. So I thought I'd try to resize the partition. Booted from my Ubuntu LiveCD and entered the partition manager. I'm able to tell the program that I want to resize the Linux-partition (so it sets the now freed space as "unused", but when I chose to "resize/move" on the XP-partition I do not have any free space. Does this mean that I have to resize the Linux-partition (until now I didn't actually resize it, only set the job as "pending" hoping that I could select both to shrink the Linux-partition and extend the XP-partition in one session), or do I have to format the XP-partition and make a new one (larger this time), then reinstall XP?
/dev/sda1 is XP; /dev/sda2 is Linux Mint

I just bought a new external 1 TB HP hard drive that came with two partitions.One larger for storage and another 700 MB partition called hplauncher as a sub-file of what shows as a CD drive called HP virtual CD 4607 which held files for windows automatic back up. Which I don't need.Both the CD and launcher drives do not allow for deletion or formatting. The larger drive does.I am viewing it in the Palimpsest Disk Utility that cam with my Ubuntu 9.10 clean install.

I am currently running a dual boot with windows 7 and Ubuntu 9.10. Is there a way to get rid of the windows 7 partition without redoing the hard drive? I know how to delete the second partition and then do a FixMbr in windows. Is there a way to do that in Ubuntu?

What happens when you wipe a hard drive which has a partition that is mounted? I was using ubuntu 9.10 live CD but I had one partition on a hard drive mounted. Then, I started to wipe the entire hard drive with random characters using dd. Only later I realized that I hadn't unmounted that partition. what could have happened? Could the Live CD have been damaged?

Is there any performance degradation or complications that arise from having Linux installed on a separate, physical hard disk from Windows in a dual-boot setup? I have a computer that I'd like to dual-boot Ubuntu and Windows but the current hard drive is quite fragmented and the Windows partitioner won't allow me to make a partition large enough to comfortably run Linux+several gigabytes of media that need to be stored. The rig, however, may have room for another internal drive, so I thought that having a separate physical disk reserved completely to Linux would be an easy solution. The tech guy at the local computer store suggested there might be difficulties with this configuration because one drive needs to be the "master" and the other a "slave", resulting in boot complications.

I'm installing fedora 12 on a laptop using the live cd, and I have a few questions about the encryption process.
First, I'd like to fill the drive with random data. I've read the fedora documentation and it suggests using the following command: dd if=/dev/urandom of=<device>. The installer didn't offer an opportunity to do this, so I opened a terminal and typed the command. I expected it to take hours on my 160 gig hard drive, but it only took about 3 minutes, and indicated about 600 megs of data had been written. Did I do it correctly? According to palimpsest, my boot partition is sda1 and the other partition is sda2, so that's the one ran the command with.
Second, I need some advice on what to encrypt. The installer shows me the following layout after I select encryption:
LVM Volume Groups
Hard Drives
I know I can't encrypt boot, but I can encrypt lv_root and lv_swap. But is it necessary to do that? And tell me the pros and cons of using a boot loader password?

I encrypted my hard drive on my media PC but it's really annoying having to type in a password every time I turn it on. I chose a short password so it was quick and easy to type in but is it worth encrypting data with a weak password?If the computer is suspended, someone could come along and resume the computer. They would be presented with a locked GNOME session) but the data would be unencrypted; does this go against encrypting the hard drive? Or does the locked GNOME session provide enough security to keep an intruder out?

I have recently bought a new laptop, installed my first linux OS on it (Ubuntu 9.10) and an external hard drive with 500GB on it for backup. For the first few days my external hard drive was working fine, but then eventually it wouldn't let me copy/move/delete stuff to and from it. So I kept trying to change the permissions but it wouldn't let me.
I figured this would be a very very common problem, so I looked up some forums to try out the methods but they didn't work. So I thought I would ask you guys for help because I am pleased with the support. I wouldn't think this would be a hard problem to solve.

What I want to do is pull data from any of the hard drives attached to my Linux box from my Windows machine. I have been moving small amounts of data from the drives to my OS drive and those parts share easily, but I want to move away from that method to move large amounts of data at the same time.I have tried using Samba as it is used for file sharing between systems and that I have to give my Windows box permission through Samba.
Trick is, I'm not sure where to start, though I have an idea and wanted to know if this is the right track before I start editing my file system.

I have an external hard drive that has all of my Apple Powerbook G4 files on it. I plugged in my "Journal Extended" external hard drive into my new HP laptop with Ubuntu 10.10 on it.
All of my files are on the hard drive still, however lots of them have a little X on the folders and when I try to open them it tells me I don't have permission? How can I force the permission for everything on my external? It's my own files and I can't even access them lol.

I want to access my hard drive to copy over my old documents. So I boot into a LiveUSB, mount my ubuntu partition, and then cd to my home directory, but I can't open it. I get "permission denied." I encrypted my whole home directory and know the password, but how do I "decrypt" it or login as the partition's root so I can access the documents that way. I'm booted into the USB, but can't access the home directory. I get "You do not have the permissions necessary to view the contents of 'jake'".

I want to move the entire contents of my backup HD to another HD. I could manually copy everything, but I was hoping to clone the entire backup hard drive. I tried to do it with Gparted, but as far as I can tell, I can't clone between drives, only between partitions on the same drive (I've done that before). So how can I do this in Linux? I think one of my drives came with a cloning utility on a CD, but I'm not sure I still have the CD.
