    Hacked


    I have a credit card that I only use on Amazon.com. In fact it's an Amazon Chase card. Last month there was an unauthorized purchase from a vendor I'd never heard of. I've been given a credit and was told that if the vendor doesn't reply in 2 months that the credit will become permanent. The letter I got from Chase showed that someone actually had my card number. My question: The number was obtained 1 of 2 ways; Someone hacked me on Amazon or hacked a password protected file with all my CC numbers. Should I 1. Change my Amazon password or 2. copy the file, print it off and hide it in a safe place after deleting the file on my computer. I probably should do both, but what was the most likely way that my CC # was obtained?

    Hi there

    1) Get your money back
    2) change password and account

    Ideally as well contact Bank (not via computer / email of course) and get OLD card cancelled and get a NEW one with different number and PIN.

    This is so obvious that I can't really understand why this is being posted !!!!!

    When it comes to your OWN money - any even niggledly problem just get a new card -- Banks will ALWAYS give you new card with pin if you ask for one.

    If Bank won't give you a new card just cut up the old one and inform them by mail (registered SNAIL mail) that you want the card cancelled immediately. I can't imagine a Bank though not trying to be co-operative on security issues.

    Cheers

    This happened to me with an iTunes purchase I never authorised. It was for a "bundle" of apps. I tried to restore one app I had that was in the bundle and it automatically "bought" the rest of the apps for me somehow. I could not deal with it the normal way, which is to find the apps in iTunes account manager and "report problem" then ask for a refund. I had to call them and they were happy to refund the bundle. I had to tell them it was a mistake rather than a forced purchase, otherwise they would have locked out my only card.

    But in this case, a replacement card is in order, because of the nature of the hack, mine might have been due to some automation I can avoid in the future.

    I don't see how anyone can get into an encrypted txt file though, how was it encrypted, through Windows 10? If so, there may be a hack available on torrent sites that anyone can use to get in to those files. Hell if they can beat Office 10's KMS, they can certainly decrypt a file. I would suggest, encrypt the file, but then add it to a password protected RAR archive, those are a little more difficult to brute-force the passwords. And the password used might have been guessed, too. Maybe someone who knew you that might know what you would use? Maybe they got the card number and the security info a different way, maybe from another purchase even.

    I have gone to storing important info like this on my hand devices, especially Apple, which are a bit harder to bust into.

    There are so many ways to obtain it, that I do not even know, where to begin. It might not even have been from the internet.
    Someone could record your card, when you were paying in a shop, people usually flash and turn card around several times.
    Another offline option is simply copying it through air, if it is contactless. You might consider RFID protected wallet/cover.
    Once you receive a new card, note the CVV code or remember it and then scratch it from the card to make it unreadable.
    As for online, never save your card info anywhere, like in a browser or an eshop. It is convenient, but very dangerous.

    Good idea, I'd do that but it is already unreadable from being in my wallet.

    How about things like Apple/Google Pay, Square Cash, Paypal, etc?

    But when you pull it out, it is not, cameras and people with phones are everywhere.
    It is a good idea to have a separate card for internet payments only, easily replaceable.
    The best option is of course to use paypal, where you do not have to enter card info at all.

    Oh that's not what I meant, I meant that the actual number is completely unreadable now, being in my wallet rubbed it off. I got to admit I never considered cameras might be able to see it, there may be security cameras all through stores that you can't see. I suppose we have to continue living our lives as if somebody can see what we're doing in some way or other.

    This could have happened in a lot of different ways. And it might not have even been recently. Often the thieves hold onto numbers for months before using them, to make it less likely for you to tie them to any specific timeframe.

    One common occurrence is that people use the same password on multiple sites, and when the password is compromised on a different site, they try them on various major sites as well. While malware could try and find creditcard numbers on your system, if it's as you say, and encrypted, then this is highly unlikely. No thief would invest the effort to crack an encrypted file unless you are someone very important.

    I never used this card in a store, only on Amazon.com. As I said it was an Amazon/Chase card. I immediately had the card cancelled and got a new one by Fed Ex. The file containing my CC numbers is not encrypted, just p'word protected. I think it was probably hacked on Amazon. Will change my Amazon p'word and print off the file containing my cc numbers, then delete the file and hide the printed copy in a safe place. Anything else anyone would suggest I should do.

    A friend had similar issue with Amazon Chase card. I would consider cancelling the card.


    Also, you may consider checking your credit report (free) at annualcreditreport.com for unauthorized inquiries/transactions.
