Title: Always, always double check addresses!
Post by: alia on February 25, 2018, 11:25:06 AM
I just got screwed out of 0.03 BTC because of a malware that changes any address you copy into the malware owner's address. It even used a vanity gen to make the two first characters of the address the same (I was sending to 1Gm..., so the malware created a 1Gm address).

1. Before sending, always check the first two and last two letters to make sure it is the same address you are copying!
2. If possible, check a random string in the middle and compare it! Even better.

Be vigilant, y'all!

Do you have any idea where you got the malware from?

No clue at all... and I'm not one to download rogue files, especially from crypto sites. It was likely something browser-based and stealthy.

That's for sharing your experience mate but this issue has been revolving through the community for a year I guess.
https://www.reddit.com/r/Bitcoin/comments/79pai0/be_careful_out_there_everyone_there_is_malware/
Have you downloaded some apps?

Do you have any idea where you got the malware from?
I guess he got it from downloading a very unfamiliar source.

I feel bad for you man. Checking the address should be a habit. Better be careful next time doing transaction.Avoid any downloads from random sites and at least use private browsing with every transaction. Having you system protected with anti virus would be a good idea as well. We are talking about hard work money here, keeping them insured is a must.

Sorry to hear that buddy. Yes, we should always check the addresses that we use to send coins because it will never be return if it happens.

you should scan your hardware with antivirus. I recommend you use malwarebyte, since i has same problem in the past and it solved my problem.
Or you can try this way
This is indeed a virus, a lot of people faced this in the last a few years. This removal method should do the trick: https://www.symantec.com/security_response/writeup.jsp?docid=2016-020216-4204-99&tabid=3
Uninstall some useless or unknown program from your hardware maybe can help but you must scan again with antivirus after uninstall it to make sure the virus is already gone.

I also experience this kind of virus on my laptop when I suddenly double-checked my ETH address on etherscan but it shows different account and has almost 70 ETH on his wallet, I double-checked my wallet address on my copy and BOOM! The address that I've been copy-pasting is not mine, but its the hacker's. I searched about it and I saw this site https://ethereumworldnews.com/careful-copying-pasting-ethereum-wallet-address/ which tells that it is Trojan.Coinbitclip which automatically replaces your 40-character hexadecimal address into theirs. Those hackers have lots of addresses so they have different options to work to. Be careful on downloading files or visiting websites as it may contain malwares and bad stuffs. Just use a legitimate anti-virus software to fix this or just reformat it. Additionaly, you can still copy-past your address using your infected device, but instead of copying it all, leave atleast 2 characters when copying, then paste it and fill the last 2 characters of your address and all will be fine.

Good thing to know because I might also have been a victim of it. Doesn't your PC has an anti malware or something? You should also make your PC secured from threats because the internet is a deadly place. Since it is my address, I am very familiar with it and I also double check it before sending.

Damn, didn't heard about this particular type of attack before. One more thing to check up every time when doing transfers.

This one is much more difficult to prevent than phishing attacks. For phishing attacks it is usually enough to just bookmark your sites and never click  on any link received trough email, social networks, etc..

Do you mind share what kind of malware that you're talking about? so all of us will aware about that.
My suggestion is, please keep your antivirus updated and don't click any suspicious link or install crappy-shit plugins that offer some magic that will solve your computer's problem.
Stay safe, and agree, always double check your address.

I have read a lot of this, but still, surprise with all the many anti-virus we have online there is still this kind of malware, I have bitdefender and malwarebytes but still looking for my address, and check if it is indeed right before sending my funds.


Title: Re: Always, always double check addresses!
Post by: puruntung213 on February 25, 2018, 02:42:31 PM
What im doing and my other friends before sending double check the address if its right were checking three first and three last character of the address to be sure we were sending in the right address


Title: Re: Always, always double check addresses!
Post by: Caesar-Giulius on February 25, 2018, 04:30:48 PM
Sorry to hear about your loss and thank you for notifying us about this. I have heard of this malware and have been checking the full address before sending.


Title: Re: Always, always double check addresses!
Post by: sasinghal on February 25, 2018, 04:43:20 PM
Yes you are right, the addressed should be cross checked by checking atleast first two and last two digits. This thing happened with one of my friend as it happened with you, he had lost 0.05 BTC.


Title: Re: Always, always double check addresses!
Post by: kueyen on February 25, 2018, 05:32:16 PM
This is a very smart way to implement a malware, no? Especially when you're copying and pasting addresses, you never feel the need to check it once again. Although I'm sad OP lost their money due to this malware, I'm amazed at how inventive this method is.


Title: Re: Always, always double check addresses!
Post by: Kprawn on February 25, 2018, 05:44:00 PM
This is why Ledger wallet implemented a new procedure, where the user confirm the "receive" address on the device and not

on the browser side. That is not necessarily Malware, because these addresses are being changed manually by the hacker. I

make a habit to triple check my "Send" & "Receive" address, before I do anything. I do not trust "software"...  ::)


Title: Re: Always, always double check addresses!
Post by: Alanpigi80 on February 26, 2018, 06:35:53 AM
That's always bad news to hear. I'm sorry OP.

A good way to protect our wallets could be using a laptop only for transactions? I don't trust antiviruses and antimalwares because of the "day-zero" that not every software have good protection

Post by: pearlsome on February 26, 2018, 07:09:00 PM
I see how accountants work in my office they compare each figure before sending money (fiat). But they can return the money in case of an error within 5 banking days. Probably, therefore, I subconsciously remembered that when listing the Cryptocurrency, you also need to compare the numbers. Since no one will return cryptocurrency in case of an error. I have not hundreds of operations a day. Therefore, it is easy to review and check.


Title: Re: Always, always double check addresses!
Post by: Mi5h0 on February 27, 2018, 04:45:23 PM
I've heard about such malware, but luckily I have never experienced it myself. I always check a couple of digits at the end of the address before sending coins.

Very unfortunate this occured to you OP and I am also sorry it happened. But however, thank you for coming to the community with this I find myself getting lazy sometimes when checking. I should be more diligent in my checks and so should everybody else, and that is what we will do from here on out.

We are now the BANKS by using the blockchain and their associated wallet. It is necessary to check, counter-check and double check the figures before sending out your crypto to other address.

To secure your PC. Make sure that you have an updated OS and antivirus. Make your PC to be solely used for bitcoin transactions. Do not install any other programs on your PC. especially the unknown programs downloaded free from the internet.

When conducting a transaction, in addition to checking the normality of the network, the receiving address must be carefully checked, assuming that once it is successfully sent, it is impossible to withdraw it. I hope you learned the lesson, you can be more cautious.

yes, this is good for other members to be more careful again to be the health of his computer. you should install security that strengthens your computer system in order to avoid malware virus attacks or some kind of phishing. reinforce with a really good antivirus.

I think right now, after reading everything, they will put their computers on antivirus check. I already do it. And yes, no one is ever insured against such cases and check the computer at least once a month for antivirus software.

Title: Re: Always, always double check addresses!
Post by: talkbitcoin on March 07, 2018, 09:00:00 AM
you should always check EVERYTHING, not just one thing you hear went wrong or possibly went wrong for yourself.

address is one of them, the other things are the amounts you are paying for example check to see if you are paying 1BTC or 1 uBTC or 1 mBTC, some wallets have different units which may cause big funds loss or underpayment.
the other thing that  comes to mind is the fees. these days with fluctuating mempool and sometimes horrible fee estimations you don't want to pay a lot higher or a lot lower than what normal fee amounts are.

Sorry to hear that buddy. Yes, we should always check the addresses that we use to send coins because it will never be return if it happens.
You are absolutely right we must take alot of care on checking out our wallets and addresses,lets see to it that it is properly copied or pasted everytime we transfer coins from one adress to another.Do make sure that the site that we have created in our wallet is legit because in this days scammers and hachers are everyewhere and sometimes our carelesness could lead us to regret so we must need to take extra careful inorder not to lose our hard erned money,we take time and efforts to earn it.It feels so embarassing when all we earn will lost  and wasted.Let us all be vigilant to avoid in experiencing this kind of situation.

       It could be a lesson for us to be careful enough and check the address many many times before we send coins. It sad to hear that there is a lot of people trying to stole their fellow. Always check every addresses we use to transfer fund,make it sure to be secure.

I read about this kind of malware from some other threads and it's kinda scary. :o For safety precautions I always check the address that I will sending my funds not just twice but four or five times more to be sure. There are lots of hackers this days and everyone should be careful on every website that they are visiting and every stuffs that they're downloading on the internet specially those suspicious one's.  8)

So I need to do it and you will check our address and after that we put our deliver to a decent area get a kick out of the chance to send to the wallet or acknowledge a great deal or fine and dandy for the position you improve a do like duplicate glue the address for no mixed up .on the off chance that you no decision can do compose at the quantities of address and you will consent to twofold check dependably at the address we put into much be watchful about address since one of our oversights is the greater part of that are now gone immediately .so my recommendation is please keep your antivirus refreshed and don't click anything suspicious connection or introduce modules with much offers most enchantment will understand your PC any matter of your concern .so remain safe and concur dependably and twofold check us at our address before you can send straightforwardly

The best thing to do is to have blockchains app for every of your wallet don't use browser base wallet to send bitcoin as there a lot of malware's that can manipulate your browser and at the end you end up being scammed.

Thanks for the advice. I admit sometimes I don't double check and I am a bit careless. But, I try to stay away from malicious websites in order to protect myself.

You have made a big mistake when downloading malware on your personal computer. This causes you to change your address when you make transactions. I think you should keep an eye on all that you do and do not download any software to your computer if you are not sure whether it is safe or not.

That can be avoided by following op's advise of double checking your addresses. It's not that difficult to do especially for something that deals with your money. And if you've been using the same address you should at least be aware of the first and the last 4 characters right? Always check.

Of course, it was always known to everyone that such a case could occur. You think that you are safe from everything, but in fact at any time of the day and night a virus can enter into our PC.
Where there is software and technology, there is virus. Viruses are dreadful no matter in which form they are. Clicking too much websites and opening things that are none of your concern, usually give passage to virus into your computer. There are many antiviruses that give strong protection to viruses but again there is no guarantee that all viruses would be combated by the antivirus you have installed. It is better to focus on preventions than going for cure.
