Within the last 48 hours, I have received link only email messages from two seperate clients that link to (domains removed so no one here clicks into what I presume is a site with a virus downloader) "/cms/modules/Search/tubyus.htm" and "/blog/wp-content/themes/tubyus.htm". A quick search of "tubyus.htm" on Google returns scores of pages ending with both of the previously listed paths attached to multitudes of random domains; yet I have been unable to find any results that link it to virus discussion or AV virus database results.

I thought I should post here because since these only came in (to me) within the last two days, and since most of the Google results (that have associated dates) have only populated since 07/14/2011, I think we may have a new virus with a payload that drops "randomdomain/blog/wp-content/themes/tubyus.htm" or a varient thereof to an infected user's entire contact list.

I will not be contacting either of these people today until much later this evening because it is my wife's birthday and I am taking her and my daughter to a waterpark to celebrate :) However, if I get back early enough and can get ahold of either of them I will connect remotely and run mbam, DDS, and GMER and see if I can identify what virus is dumping this payload into their email and post the results here.

I'm not sure if I have posted this in the right loaction, but as this virus payload appears to be less than 72 hours old and relatively widespread based off the google results, I thought I should put a 'heads up' on here as a courtesy :)

Instead of running DDS please do the following:

Hello,

And welcome to BleepingComputer.com, before we can assist you with your question of: Am I infected? You will need to perform the following tasks and post the logs of each if you can.

Malwarebytes Anti-Malware

NOTEMalwarebytes is now offering a free trial of their program, if you want to accept it you will need to enter some billing information, so that at the end of the trial you would be charged the cost of the product. Please decline this offer, if you are unable to provide billing information. If you want to try it out, then provide the billing information.

Please download Malwarebytes Anti-Malware and save it to your desktop.
Download Link 1
Download Link 2MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.

  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
    For instructions with screenshots, please refer to the How to use Malwarebytes' Anti-Malware Guide.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Full Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Now GMER

GMER does not work in 64bit Mode!!!!!!

Please download GMER from one of the following locations and save it to your desktop:

  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.

    Posted Image
  • GMER will open to the Rootkit/Malware tab and perform an automatic Full Scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.
-- If you encounter any problems, try running GMER in safe mode.
-- If GMER crashes or keeps resulting in a BSODs, uncheck Devices on the right side before scanning
.


All scans above should be performed in regular boot mode, and if that is not possible then I will post instructions in a follow up reply on how to get into Safe Mode to perform the scans. Also all scans should be COMPLETE and not quick unless specifically instructed to do so.

Will do! I suspect whatever it is will not be present for the remaining scans after MBAM runs, but we'll run SAS and GMER just to be safe. I am certain I would have heard from one or both of these clients if their PCs were doing anything abnormal (slow connectivity, redirects, popups) so my gut instinct tells me that the script or downloader is present on the linked site and not on these client's PCs. I suspect that the virus they have is a mailer only variant designed to draw as little attention to itself as possible, and usually in those cases, MBAM handles the infection without difficulty.

I tried contacting them as wife and daughter are both still getting ready, but neither answered, so I'll have to wait till this evening to determine the offending virus on their PCs.

I just received two of these emails linking to tubyus.htm from the same person. They aren't spoofed, and actually being sent from the person's account. Two different domains (rshfirma.kilu.de & mussock.co.nz), one is /modules/Search/tubyus.htm and the other was /shop/images/tubyus.htm. This thread is the only thing I've seen on Google that was a discussion about it. I didn't click on any of the links(I'd love to have a isolated box to see the results of clicking on one of those links).

Well, I am back from the water park and neither person is available to check their systems. Oddly, one of them is on a macbook, so while I was thinking about it at the park, I thought maybe it was hotmail's server that got hacked, but now that I am home, I see that one of the people I received this from was a yahoo and the other was hotmail, so it isn't a mail server side hack.

I am curious about the macbook specifically... I was under the impression that macs were still 'security by obscurity' and it seems odd that this virus payload could have originated on a mac.

I am going to keep trying to get ahold of them in the meantime.


Edit to add: What would I even use to check the mac if once I get ahold of her she says she hasn't used any computers besides her macbook? I don't think any of the tools listed above will even run on a mac... :huh:

Ok so I did more research as I am unable to get ahold of either of the people who I received this from. I decided to dig more into the email provider end since I felt it unlikely that whatever was dropping this payload was written for both windows and mac OSs' simultaneously. Looking through the search results for tubyus.htm, which incidentally have more than doubled since I posted this yesterday, I have found that about 60% show yahoo email addresses in the description, 30% gmail and 10% hotmail. Results with email addresses make up only a small portion of the total results, and the vast majority are comment or forum spam which are for the most part posted by users who registered on those forums using one of the above mail providers as opposed to bot comment spam which you'd expect.

My conclusion is the two people who I received this from have had their mail provider accounts hacked, especially since I am doubtful that it is a local virus on the macbook. I'll keep digging since this appears to be just the tip of the iceburg with this from how rapidly google results on the subject are growing and this seems to be the only discussion on the subject.

Well I did a wget on one of the domains in question, and that htm file contains a re-director to a Canadian pharmacy site.

Interesting, a redirect to an out of US pharmacy site doesn't seem on the profit level that I was expecting considering the magnitude of results within 72 hours and the multiple domains involved and methods in which it is spreading. I frankly expected at the very least a vundo variant popping scareware at $50 a pop as opposed to shady marketing by a "Cheap Viagra" site...puzzling

I feel kindof stupid now, a simple redirect is hardly BC worthy.

Ok, so it turns out the macbook user's daughter accessed her mom's email and a few websites from a Windows PC the day I got the redirect mailer from her. It sent out mailers in groups of 3 addresses to her entire address book 300+ people. 81 were rejected by servers for containing viral content, so there is something viral hitting her locally. I am going to be checking her system at 11am eastern and will post the MBAM, SAS, and GMER logs to see exactly what virus is delivering this payload :)

ETA: Oh and I almost forgot, the redirect is more than just a pharmacy site as she got the link from a friend who sent it to his entire contact list and she actually clicked on the link prior to her system sending out it's payload.
