Ubuntu Security :: Trojan Virus Keeps Coming In Share Directory?

Sep 27, 2010

After some time i always see a trojan virus in my ubuntu machines shared folder. It is an exe detected by ClamAv as Trojan.Autokit-77 I thought i was getting it from some windows machine on the network but that isn't the case. I deleted the virus and removed my computer from the network and still the virus comes back. My computer however, is still connected to the internet through an independent mobile broadband usb stick.

So where is the virus coming from and why is it going to my shared folder. I thought ubuntu would not allow the virus to do something like this without me giving it permission. I am running 10.4.

Ubuntu Security :: None Windows Computers Firewall And Anti-virus Program?

Feb 28, 2011

I tried to ask this question in the other thread but the admin was saying to me that my other thread here [URL]..( it was not very much the subject of the thread ) People that use Unix,Mac OSX or any Linux OS all none windows do you need anti-virus program like Norton or Kaspersky? And same with firewall like ZoneAlarm and Comodo ?

Some people say you do not need a anti-virus program like Norton or Kaspersky or any firewall.Other people say you do and some say that Unix and Mac OSX have built in firewall.

And if on uses windows use ZoneAlarm or Comodo has it does alot more than windows firewall and router firewall. Note the admin saying the other thread was why windows get more malware and not very much the subject of the thread to post there.

Ubuntu Security :: Virus Resides In The MBR And "rebuild" The MBR To Actually Remove The Virus?

Jul 15, 2010

I have a dual boot computer. The WindowsXP "side" has been infected with a rootkit virus. So far UBUNTU has not been affected to my knowledge. I have not yet removed the virus from the WindowsXP "side". I am thinking of deleting the NTFS partition and have the computer fully dedicated to UBUNTU. Now for my question. Is there a possibility that the virus resides in the MBR and that I need to "rebuild" the MBR to actually remove the virus?

Even more extreme, should I totally re-install UBUNTU in the name of safety and precaution.

Ubuntu Security :: ISP Keeps Complaining About Infected Computer

Feb 27, 2011

For a while my ISP has been sending me emails regarding an infected computer or computers on my local network. There are 4 computers running linux and 3 running windows on said network (3x ubuntu, gentoo, 2x windows server 2003 and windows 7).Now, I haven't used Windows in oh so many years and am not responsible for those computers on this network. Does it seem like this is a virus on a Windows host or should I research and adjust my iptables settings on the router? The applied anti-virus software (I don't know which one) apparently does not find any infections. On my workstation I'm using spotify and win32 office through wine, both obtained from legal and trusted sources, and would thus not consider my wine environment a threat.

I recently ran a virus scan on my CentOS server using ClamAV's "clamscan" command to scan my entire system for virus. After the scan was complete it says that I have 1 infected file on my computer. I COMPLETELY FREAKED OUT! Is there some kind of log that I should read to see where the infected files are? Also does ClamAV just scan your system for virus or does it scan and remove the virus on the computer.If you know of an alternative open source security software,

Security :: Computer Has Been Infected With Trojans?

Jan 7, 2010

I'm now running Ubuntu 9.04. There are 2 accounts on this computer, one is linux, the other is ubuntu. Before New year, everything had been fine. But after new year, I came back and found that the password of this account linux has been changed. So I fixed using my rescue disk. But since that day on, it seems that this password changes everyday somehow. Everyday when I'm trying to log into my Ubuntu System using the account linux, it says login failed. However, i can still login using the account ubuntu. I'm really confused. Why is this? I checked the date of expiry. Everything seems to be fine.

Security :: Transient Rkhunter Warning Of Sebek/adore Trojan On Desktop Debian?

Feb 22, 2011

Like Jackp27, I am reacting to a transient warning from rkhunter, indicating a possible LKM trojan, which may or may not be a false positive. Running chkrootkit and rkhunter repeatedly, including older versions running under live CDs like INSERT, indicated nothing wrong, but two runs of rkhunter running under the possibly compromised system itself did seem to suggest rkhunter thought it might have found elements of trojan code in RAM.

Like Jackp27, I can't give details right now because I do not currently have access to my logs, but I did find one webpage (can't give link because I do not currently have access to my detailed notes) suggesting that rkhunter may have thought it found a signature of the adore trojan in RAM by looking at /proc/kallsymms which is not a file I ordinary look at. I did look at it very closely yesterday, repeatedly, and it seems to be mostly empty, but occasionaly seems to contain what might be a sequence of calls to various kernel modules--- right now I only recall that some had the form ??_guest_? and that x_tables might be involved.

Can anyone give me a rough indication of what /proc/kallsymms is supposed to do, whether it should normally be empty, and when it is not, what kind of lines are supposed to show up in that "file" when I cat it? I also saw something about ?_logdrop? which may have had something to do with with rotating logs (I rebooted several times) rather than a trojan keylogger. But maybe some trojans rotate logs to try to hide their presence?

I know I am not giving enough information--- I hope to come back later with more details after I have managed to access my logs and notes, so feel free to say what kind of details would be most helpful in helping me decide whether or not this was a false positive.

Security :: Detect Infected PC In LAN (Sending Packets To Internet)

Jul 17, 2009

In my network I have 25 workstations and some serves. Everything working in local LAN with firewall. The problem is that on one machine (I dont know which one) is installed software which sending data to the internet. Actually I dont know what it is. Last time as I remember was trojan which can create new network interfaces in windows and send some data to the internet. The half speed of my network connection is used by this infected machine. How can I detect which machine it is? How can I listen/capture some traffic and analyze from which machine I have more connections.

Please take a look on this time. Instead of 141-150ms should be 4-5ms.

Security :: Compromised Systems Notify Hacker They Are Infected

Dec 4, 2010

I have a server connected to the internet placed in a DMZ that was running ProFTPD. A couple of weeks ago there was a security threat uncovered that would grant access to external users through a buffer overflow. Of course I patched my ProFTPD quite often after that to secure my server. Now my problem is that the servers of ProFTPD were compromised and that source code with a back-door was released. To make matters worse compromised systems notify the hacker they are infected. is there any way to ensure I don't have a root-kit installed short of reinstalling the system?

Ubuntu Security :: Safe To Transfer Files From Infected Windows Partition?

Sep 2, 2010

My Windows XP Pro laptop has been attacked! Windows will no longer update and Microsoft Security Essentials will not update either. I've been trying to resolve the issue for over two weeks with Microsoft support, but it's just taking too long. I also tried some rescue CD options (all running some form of Linux, obviously):

- BitDefender Rescue CD (removed infections, now detects nothing),
- Kaspersky Rescue CD 10 (removed infections, now detects nothing),
- Trinity Rescue CD (won't load AV Engine, so can't use it to do anything).

Malwarebytes cleaned a bunch of stuff, but will not clean the final threat detected (it's supposed to get deleted on reboot, but never does). Hijack.FolderOptions is stuck in the accursed registry, and it keeps causing Windows Explorer to crash. I cannot rename files or work with them or everything just crashes.

So I'm ready to reinstall XP from scratch, and add a dual boot with Xubuntu & LXDE, which I'm already running on a much older laptop.

Question: I want to rescue the files I need. My idea was:

1) Install Xubuntu with dual boot.
2) Copy over files from Windows XP partition using Xubuntu.
3) Back up files to an external drive using Xubuntu.
4) Reinstall XP Pro and format hard drive.
5) Reinstall Xubuntu with dual boot.
6) Use Xubuntu for daily use.
7) Only use XP for those tasks that require it (TomTom updates ...)

Should I be concerned about the security risk from copying files from the Windows partition to the Xubuntu partition, and from there onto an external hard drive?

Is this the way to do it, or is there a better way? I just want my laptop back in working order. Right now I can't use it for anything.

Ubuntu Security :: Using Ubuntu To Remove Trojan From Windows 7

May 31, 2011

I stupidly clicked on a spam link on my roommate's computer (I must have forgotten that I wasn't using Ubuntu and had to be much more careful) and the computer is now infected by a nasty Trojan. (I unfortunately cannot remember the name right now, but it is a Trojan.) Now, her computer will barely start up under the normal Windows 7 without a blue screen of death appearing, with the IRQL_NOT_LESS_OR_EQUAL error message.I stumbled upon this: http://maketecheasier.com/remove-win...ux/2010/02/02/ and I thought I would give it a shot.I don't have a flash-drive, and I'm rather tight on cash at the moment, so instead of creating a USB stick with the OS they recommended, I used my live CD of Ubuntu 10.4. I installed Clam, and ran the update as it says, and it seemed to work alright. When I started the scan, however, (excluding .doc files), the first message that came up was that the software was out of date, but the scan proceeded, and so I figured all was alright. The scan took about an hour 45, and when it was done, it reported that 0 files were infected, and that there were 4 errors. I crossed my fingers and hoped that these errors were the problem and Clam fixed it, but alas, this was not the case. The computer is still just as screwed up.

Does anyone have any suggestions? Maybe the updates couldn't be saved because I was using a live CD instead of a USB? Hopefully this isn't the case, because I really don't want to have to go and buy a flashdrive, but I will if I must. Can a portion of an external harddrive be used as a boot drive?
