Credit Card # Stolen; Logs Attached

    I received notification from my bank 1 month ago that my debit card # was compromised. I canceled the card & received a new one a few days later.

    Of course I do a lot of online shopping (who doesn't?) and when the new card arrived, I continued w/business as normal.

    I received notification yesterday from my bank that it had occurred again. At this point, I have to believe it's something I've done. Either using the same online store (that their records were compromised), OR my computer is infected.

    I have NOT noticed any suspicious behavior. I did however run Malwarebytes immediately and had 11 issues (Log attached). I have yet to successfully run combofix, it stalls out each time (I let it sit for numerous hours untouched and it never finished). I have attached all other requested logs. Again, I have not had any real suspicious behavior but I truly believe it must be something with my wireless network or laptop.

    Will post 2nd post with RootRepeal Log.

    Any suggestions or help are much appreciated!!!

    Welcome to Major Geeks!


    Please answer all of the below questions:
    1. Did you use any other PCs to make purchases at anytime?
    2. What online stores?
    3. Have you contacted all stores to ask them about any potential issues?
    4. Does anyone else ever have access to your PC?
    5. Have you changed the passwords on your PC and to all of your online accounts ( all accounts everywhere ) including email accounts?
    6. Why do you have LimeWire running at startup and have you had this active while doing online purchases? This leaves your PC open for unauthorized access!!! You should uninstall this and stop using it or anything like it.
    You only attached the one that is clean. We need to see the below two logs:
    Code:
    "C:\Users\JustinElders\AppData\Roaming\Malwarebytes\Malwarebytes' Anti-Malware\Logs\"
    Dec 29 2010  1898 "mbam-log-2010-12-29 (21-13-05).txt"
    Dec  3 2008  4169 "mbam-log-2008-12-03 (21-35-26).txt"
    Did you have all of Symantec disabled before trying to run ComboFix? Please try again. Try safe boot mode if normal bootmode will not work.

    There are no obvious signs of password/info stealers in the logs you have attached thus far but let's cleanup a few things.



    Now download The Avenger by Swandog46, and save it to your Desktop.
    • Extract avenger.exe from the Zip file and save it to your desktop
    • Run avenger.exe by double-clicking on it.
    • Do not change any check box options!!
    • Copy everything in the Quote box below, and paste it into the Input script here: part of the window:
    • Now click the Execute button.
    • Click Yes to the prompt to confirm you want to execute.
    • Click Yes to the Reboot now? question that will appear when Avenger finishes running.
    • Your PC should reboot, if not, reboot it yourself.
    • A log file from Avenger will be produced at C:\avenger.txt and it will popup for you to view when you login after reboot.

    Now let's flush the Java Cache

    • Double click the Java icon (be patient, it may take a while to open)

    [*]Did you use any other PCs to make purchases at anytime?

    Not that I remember, I normally only use this computer.

    [*]What online stores?

    I own a web boutique & shop from numerous vendors online...I've probably shopped with over a dozen vendors with the new card and tons with the old one that was also compromised.


    [*]Have you contacted all stores to ask them about any potential issues?

    No but again, so many vendors. I know that increases my chances of this occuring but I'm trying to rule out that it's not my laptop being infected and that I'm not the cause of this issue since it happened twice in 30 days.

    [*]Does anyone else ever have access to your PC?

    No.

    [*]Have you changed the passwords on your PC and to all of your online accounts ( all accounts everywhere ) including email accounts?

    Yes did that this morning.

    [*]Why do you have LimeWire running at startup and have you had this active while doing online purchases? This leaves your PC open for unauthorized access!!! You should uninstall this and stop using it or anything like it.

    I honestly forgot that LImewire was on my laptop until yesterday --- haven't used it in well over a year. I removed it yesterday via add/remove programs -do I need to do anything else?

    [/LIST] You only attached the one that is clean. We need to see the below two logs:
    Code:
    "C:\Users\JustinElders\AppData\Roaming\Malwarebytes\Malwarebytes' Anti-Malware\Logs\"
    Dec 29 2010  1898 "mbam-log-2010-12-29 (21-13-05).txt"
    Dec  3 2008  4169 "mbam-log-2008-12-03 (21-35-26).txt"


    I attached the two logs you requested

    Did you have all of Symantec disabled before trying to run ComboFix? Please try again. Try safe boot mode if normal bootmode will not work.


    Still freezes up

    Now run GMER per the below instructions and attach the log
    GMER - running with a random name


    GMER ran and then after 20 min it encountered an error and had to close. Should I run again?


    Everything is attached as requested. Again, I didn't really notice any suspcious activity on my computer in the first place but I really am concerned that my computer could be the cause of the issue since it happened twice within a 30 day period on two different cards. Thanks for all of your help, awaiting your response.

    Other than what has already been removed, I'm not seeing any remaining issues. I still cannot be sure that this PC was the cause of your credit card info being stolen. The only item indicating possibly theft of info was the below seen in your Malwarebytes log.
    But even this does not really mean that the problem originated from your PC. Yes there was some malware removed and it is possible that it was the source of your problem but we really cannot really say with 100% certainty that it was the cause. It still could be a problem with the sites you are buying from. They may or may not be legit sites or they could even have a problem with infections on their side.

    In many cases, the most reliable thing to do in situations like this is to back up personally data, and then format and reinstall to be sure your PC is clean. And before reconnecting to the internet, make sure it is properly protected.

    Also note, that if you changed your passwords/logins using this PC, there is still a risk that they were stolen again( I would say a low risk but no impossible ). You should have used a different known clean PC. Also you will need to track closely for the next few months all transactions. You also may want to read the below:
