Trojan again - my son didn't finish cleaning a rootkit

Unread postby mwarrior » April 2nd, 2009, 7:56 pm

It looks like you all are snowed under, and I'm sorry to add to the load. My son had a rootkit along with a back door, some trojans and other nasties thrown in. He reluctantly posted here and got mostly through with cleaning it. You can see the log here:
viewtopic.php?f=12&t=35865&p=361692#p361692
This computer gets a lot of use online (work downloads and then teen use), but it gets the least amount of attention to security. Bad combination, I know. Yesterday Malwarebytes detected entries disabling notifications in the security programs. Removed and rescanned (checking for updates first) and was clean overnight. Today there are trojans found. The only use that I know about in that time frame is to a work site (pdf files mainly). At this point, I'm not sure if we should just reinstall windows because of the rootkit possibly still being active. I don't know if this is connected, but I recently moved all the icons from the previous cleaning to a folder on the desktop. Combofix wouldn't move, but I moved these icons: smitfraud fix, gmer, rustbfix, and windows pro boot disk. My son didn't finish with the helper, so all the tools got left on this computer.

Note the number of files scanned (and time difference) in the last mbam log and the next one - 4,000 file difference. No one has deleted any files.

Here is the HJT log:

Re: Trojan again - my son didn't finish cleaning a rootkit

I'm sorry you have waited so long for a reply... as you've noted, we're very busy.

I have looked through the previous topic dealing with this system and my best advice to you, given the type of malware that was infesting the system, given the immediate return of problems, and given the length of time that the malware has had in which to entrench itself, is that you reformat the computer and reinstall the operating system.

If you have questions, I will do my best to answer them for you.

Re: Trojan again - my son didn't finish cleaning a rootkit

Unread postby mwarrior » April 18th, 2009, 12:27 am

Hey, thanks for the reply. I really appreciate you looking it over. Your advice sounds right to me. Here are my questions:

1)When I transfer files from the infected machine to an external hard drive, do I have to worry about something lurking in there? I'm not talking about executables, mainly jpg and doc files.
2)Is there anything I need to know in regards to security when reinstalling? My teens are oblivious to security issues (no matter how many times we've had the conversation), and they will do the reinstall. I need to know my stuff before they get started.
3) Is Open Office (open source word processor) safe?
4) Should we reinstall the whole wired network (3 wired XP and 2 wireless Vista)? My computer will not boot into safe mode, but I have a USB keyboard (not sure about the set up). I've looked at my HJT log (I know a tiny bit about looking up each line thanks to MRU) and I don't see anything fishy. I'm just wondering if a rootkit can install a worm? We are able to save things to each other's computers (I don't know if that is what is meant by file sharing). All our computers stay up to date on windows patches with the automatic update.
5)My son likes Zone Alarm and I use Comodo which he hates. Is one better than the other? I tried to tell him that it's the settings that matter....He likes ZA because it never pops up like Comodo.
6)One of us has used paypal with the infected computer. I have a strong 20+ pw with upper & lower case, numbers, and special characters. If there is a keylogger, does the strength of the pw matter? Should we change it? It was changed recently.

Thanks so much for your time!

Re: Trojan again - my son didn't finish cleaning a rootkit

Unread postby NonSuch » April 18th, 2009, 3:22 am

You're very welcome. :)

As you have had a rootkit on this system, it is possible it may have hidden and protected a backdoor trojan from being discovered.

Rootkits and backdoor trojans are the most dangerous and most widespread type of malware. Backdoor trojans provide the author or "master" of the Trojan with remote "administration" of victim machines. Unlike legitimate remote administration utilities, they install, launch and run invisibly, without the consent or knowledge of the user. Once installed, backdoor trojans can be instructed to send, receive, execute and delete files, harvest confidential data from the computer, log activity on the computer and more.

I would counsel you to disconnect this PC from the Internet immediately. If you do any banking or other financial transactions on the PC or if it should contain any other sensitive information, please get to a known clean computer and change all passwords where applicable, and it would be wise to contact those same financial institutions to apprise them of your situation. Yes, this would include PayPal and, no, it would not matter that you had a strong password as the password, strong or weak, could have been sent back to "home base" by the malware.

In addition to the rootkit that has been identified, this system may be afflicted with other infections. Although an attempt could be made to clean this machine, it could never be considered to be truly clean, secure, or trustworthy. We could not say definitively that unknown and unseen malware will have been removed, nor would your system be restored to its pre-infection state. We cannot remedy unknown changes the malware may likely have made in order to allow itself access, nor can we repair the damage it may possibly have caused to vital system files. Additionally, it is quite possible that changes made to the system by the malware may impact negatively on your computer during the removal process. In short, your system may never regain its former stability or its full functionality without a reformat. Therefore, your best and safest course of action is a reformat and reinstallation of the Windows operating system.

You do not need to boot into Safe Mode to do a clean install of your operating system. You do need to change the boot order in the BIOS so that you can boot from a CD, unless your computer's manufacturer utilized a restore partition. In that event, the reformat and reinstallation could be initiated by pressing the appropriate key or key combination during a reboot. If your computer does not recognize a USB keyboard until it has loaded Windows, then it will be necessary for you to use a PS2 keyboard during the reformat and reinstallation process.

Prior to reformatting the system, you may back up your important data to CD or DVD. Under no circumstances should a USB device be plugged into the infected computer in order to transfer data to it as any such device could easily become infected and may then transfer the infection to other computers or back to the newly cleaned computer. No files should be saved other than documents and pictures. No screensavers, no executables, no program set-up files... just documents and pictures. Otherwise, the infection will be reintroduced to the newly reinstalled operating system. All data files should be scanned with anti-virus and anti-spyware programs prior to being returned to the hard drive after it has been reformatted.

If you have used an external HD and/or any other type of USB drive device on the infected computer subsequent to it becoming infected, the device or devices should be scanned and disinfected or reformatted prior to using them again.

Prior to reformatting your computer, make sure you have downloaded the setup file for your anti-virus of choice and have the disk with your computer's drivers on hand as well. Whatever third-party firewall you prefer should be fine; however, do keep in mind that if Zone Alarm never "pops-up" it's not popping up because it's either been configured to let specific applications through or it's just letting everything through. ;) After a firewall has been "trained," it shouldn't be constantly asking, again and again, if a particular application is permitted to access the internet, etc.

I would install both XP's SP3 and IE7 prior to installing either the firewall and/or the anti-virus, with at least two reboots after installing SP3 and IE7, and prior to installing the AV and firewall. It would be simpler and more convenient if you have both of these saved on a disk.

No peer-to-peer software of any kind should ever be installed on the system. "Safe P2P filesharing" is like saying "honest crook," it's an oxymoron. If anyone is using P2P filesharing, the system will immediately be reinfected, so it's pointless to even bother going through a reformat and reinstallation of the operating system as it will only become a giant paperweight within a week or so anyway.

Filesharing within your own home network is "intranet" filesharing. That is not the same as peer-to-peer filesharing on the internet. Assuming all your computers are clean, and none have been used for P2P "internet" filesharing, that should be safe. However, if the infected computer, while infected, has been swapping files back and forth with the clean computers, you may have a problem, depending on the files that have been swapped.

Open Office is good software. One caveat, be cautious about the download source for anything you download. Wherever possible, download from the developer's site; otherwise, download from a well-known, good, reliable source of safe software. Do not ever download software from some torrent site. Good software can easily have bad code planted in it, and that happens quite frequently at torrent sites. Downloads from torrent sites often are touted as "free" versions of commercial software. There's no free lunch. The price of such software comes in the form of the infection it will install on your computer.

If any of the computers on the network have exhibited odd symptoms that may be indicative of a malware infestation, and/or if you have been swapping USB devices between the networked computers and the infected computer, it is quite possible that they are also infected, whether they are connected to the network wirelessly or wired... it makes no difference.

For your own information, here is a link to a web site that has good graphic instructions on how to do a clean install of Windows XP. Even though you won't be doing this yourself, it can help you to understand the process:

As the resolution of this issue requires a reformat, and there have been no further questions posted regarding that process, this topic is now closed.
