Got hacked, lost 11 BTC

[2Pizza410000BTC]

Yesterday I lost 11 BTC from my Bitcoin Core 25.0 wallet.  The wallet wasn't open at the time.  I don't know how it happened. Lots of emotions right now.  

I am sorry for your loss, be it story or reality. But I want to ask you why you put 11 BTC in a careless wallet. 11BTC means huge amounts of money. Why don't you put a strong hardware wallet offline? People will learn from your loss but your loss will never be recovered. Your wife may not have done such a thing. You may have given your wallet seed phase somewhere.

That is why it is said that the cryptocurrency market is extremely risky. here you have to make a good choice as well as adopt the best ways to preserve it. It's great if someone can buy such a large number of bitcoins, but it's even better if they keep it safely. You have been careless in securing your bitcoins. First of all, you should not have kept all your bitcoins in one wallet rather it should have been divided. Apart from this, there are also very good hard wallets in the market right now where you can store your bitcoins. Online wallets always have more chances of hackers to attack.

I have a hard wallet, but I still don't keep all my assets in one wallet, instead I'm trying to buy another one, so that if one wallet is accidentally hacked, So there is no fear of all my assets being stolen. Similarly I don't keep my assets on any one exchange, but I keep my trading assets in different exchanges. However, we all realize and newbies must realize that hackers are always active in this market, and our small mistake can lead to a big loss for us.

It's sad to think even with 11 BTC holdings, OP didn't even think of buying a cold wallet to protect his investment. It's a huge amount of money, and shouldn't take it easy when it comes to security. I agree with you, this won't happen if he has a hardware wallet. His wife may not cause a hack if he at least think of the security of his holdings.

You are absolutely right in this statement. But that doesn't mean my assumption is wrong.

You, everyone else and I can only guess what is true and what is fiction in this thread, and until there is solid proof that the OP is telling the truth, no one is wrong.

It would be logical to write what you think the topic should be locked for - and you already wrote that in your post "OP is troll, no proofs, no signed messages". Although keep in mind that mods don't have to share your opinion and won't do anything.

Is such a free interpretation suitable for a report? I thought the report should be short. It turns out there is no single standard form for reports? Please do not evade away from newbie answers and provide at least a sample of a correct report

There is no point in going further off topic, and if you are interested in something more about how to use the "report to moderator" option, you can open a thread on that topic in the Beginners & Help board.

If we have 1k dollar BTC then we will think about buying a hardware wallet to give more security to that BTC. Because 1k dollar BTC is very valuable to me. Also I don't access anything like (airdrop join) with this wallet which I use to take weekly payments. In this case how did the OP keep 11 BTC and use that wallet carelessly. In this case I find it very difficult to accept.

I think we shouldn't make assumptions in this case.  OP still has not shown real proof that he owned 11 bitcoins to begin with, even though he said he would provide evidence.  The only parts of his story that have been confirmed are a couple blockchain transactions, but honestly those could mean anything - for all we know, he just found some random transactions on the blockchain and claimed they were hacks.

My PC is running back up right now. I'll post the signed message after it finishes and I figure out how to do it. If you feel you need to report this post, by all means, do what you feel need to do

Steps:

download eletrum wallet (from its official site)
open your wallet
copy the address to sign
click on tools- sign/verify message
write the message
paste the address
click on sign
copy the signature and share here.

You can't sign a message without the private key, if it was that easy, a certain satoshiwannabe would have done it already instead of forging.
And signing a message is impossible without a working PC, when someone gets hacked, they won't simply back up their hard drive, instead they'd take out any private key and wipe the drive clean.

But these kinds of imaginary hacks happen from time to time, there was even a person claiming that someone took 100 k BTC without having a private key by only having a signature. These are very similar to certain satoshiwannabe wet dreams, they even have a scam coin where they can block and reverse any transactions at will.😉, to be honest it's a perfect cash cow, get hacked, reverse, rinse and repeat, and what we have a lot of, are idiots to buy such scams. So kind of a wet dream.

I understand why you are trying to say, but can you show me a similar thread that received merit because they lost their Bitcoin? This isn't a topic that looks like a merit fishing stuff, maybe I am wrong but sorry to say I won't dare merit this post at all, 11BTC is gone, what will merit do at this point? I feel sorry for whoever this person is but what does this have to do with merits? It solves nothing to this problem.

They must have done something wrong using the crypto wallet without them knowing, it can happen to anybody but there is no way this will fetch him merits, if he truly want merit he would have talk about ways to avoid the mistakes, things beginners need to do to avoid getting their Bitcoin wallet compromised?

There is no single tutorial or even advice, he merely shared his painful experience, with the way you think, imagine if this is real? Have you even consider to think it this way?

You're right; I might be a little harsher without it being necessary. After all, we're all innocent until proven guilty. To correct my statement, the majority of the threads I mentioned being created for attention from newbies were regarding lost Bitcoin that was supposedly bought in the early days. I can possibly find a few because I remember replying to some of them. I don't know if this incident is real or not; I'm hoping it's not, because losing 11 bitcoins is tough and a burden that isn't easy to carry, but still, it doesn't make too much sense. Any reasonable person would have gone ahead and taken steps to secure this kind of money.

I'm not judging if someone doesn't know how to sign a message either, as it's something that I haven't done myself either; however, something doesn't add to this story. Is it the way the bitcoins were lost, or is it because the OP might not be telling us something more vital to explain how it might have happened? I don't know. In the first two transaction IDs, the sender address (ending in -rxx0a) shows a total of 28 bitcoins received. I can't fathom that the OP was dealing with such great amounts of money and kept them unsecured on a shared computer. The other two feature another wallet with dusty amounts of BTC received in them.

Once I had $600 stolen from Jaxx, and at that time the whole Internet knew that this wallet was being hacked  easy, but I did not have this knowledge. It was a shame and now I wish you inner strength and peace of mind as you have lost quite a bit. Did you have an antivirus installed?
The licensed version of windows?
Maybe the wife installed some kind of program without a license? People who are poorly versed in computers often clog up the computer with bad applications.

According to his last message, he has access to the seed or private key, he just doesn't know how to sign with Segwit.
therefore he can do it with electrum.

I am sorry for your loss, be it story or reality. But I want to ask you why you put 11 BTC in a careless wallet. 11BTC means huge amounts of money. Why don't you put a strong hardware wallet offline? People will learn from your loss but your loss will never be recovered. Your wife may not have done such a thing. You may have given your wallet seed phase somewhere.

OP made a costly mistake by putting such an amount of Bitcoin in such a wallet and you are right that he should have got a good hardware wallet. But he didn't put his coin in a careless wallet, Bitcoin Core 25.0 wallet is a full-node wallet and is considered to be one of the safest wallets. Its ability to download and validate the entire Bitcoin blockchain makes it one of the most difficult wallets to attack. It is also an open-source wallet which means that everyone have access to see, make comment, or propose a change to the code.This fact has made members doubt the story and want him to sign a message.

But splitting his coins into different wallets would have been ideal if he was using a software wallet. If I were him I would have shared my coin into a different trusted wallet or better still buy a hardware wallet. It is far cheaper than losing such an amount. However, some persons might be scared of ordering a hardware wallet because of the high rate of criminal activities. People are afraid of ordering fake wallets or compromised wallets. Even if they order from the right source, delivery services in some countries cannot be trusted. In a country where cybercrime is high some delivery service staff can change the wallet or compromise the hardware wallet to steal the coin. Using an air-gapped wallet could also be a sound option..

This must be a bad feeling. At what time, did you acquire this BTC at what price ? It is still a big loss at current prices.

I'm also skeptical about the OP's story. Put yourself in his shoes, if you had 11BTC, would you leave it on a computer with an internet connection and let everyone use it freely? I bet no one here would let that happen even to a newbie, let alone someone who has been involved and has long experience like the OP.

In case someone owns 11BTC, I think they would even store it on 2 to 3 hardware wallets instead of on one computer with an online connection. OP should provide more evidence instead of just providing the wallet address and nothing to prove that he actually owns the wallet.

[Z-tight]

If we have 1k dollar BTC then we will think about buying a hardware wallet to give more security to that BTC.

There is nothing such as '1k dollar BTC', these are two different currencies that you have just sandwiched together, you should rather say you have 0.027 BTC or $1k worth of BTC.

But he didn't put his coin in a careless wallet, Bitcoin Core 25.0 wallet is a full-node wallet and is considered to be one of the safest wallets.

BTC core is only a safe wallet when it is run in an airgapped device, just because it is a full-node wallet does not mean it is safe by default, if you run BTC core in an online machine and in an unsafe enviroment, your funds are prone to hacking.

Its ability to download and validate the entire Bitcoin blockchain makes it one of the most difficult wallets to attack.

This is not true. BTC core is a full node wallet and you can download the blockchain and verify everything locally, this protects your privacy and also protects you from connecting to malicious third party nodes, but it does not secure your funds from hackers or malware or from every form of online attack if you use it in an online machine and in an unsafe enviroment.

One final post, then I'm just going to look forward and leave this mess behind.  Some points.

1. I'm an idiot.  I accept that. I hope sharing this experience can help others avoid the same mistakes that I made.

2. I can't figure out the message signing with the segwit address.  Wish that worked with the Bitcoin Core GUI wallet. Tried Electrum, but had no luck.  Not something I need to waste time with at this point.  If there is a mod or a trusted member of the forum willing, I'd be fine with sending some sats to them from my wallet. Send me a private message.  As others have said, that still doesn't prove anything, so whatever.

3. I joined this forum about 10 years ago.  I don't visit very often these days.  Merit points or whatever mean nothing to me.  Give me negative merits, just does not matter.

4. I have reported this theft to my local police as well as filed a cyber incident report with my state and the FBI.  I don't expect anything from that outside of being a statistical data point.

5. I know exactly where this malware came from that got us.  Website, file name, time, etc.

6. I contacted one of those recover your Bitcoin bounty hunters, but it's a scam.  I figured as much, but wanted to hear what they were going to say. The BS they were spouting was kind of funny.
 
7. I still love Bitcoin, my wife and my life. While this really sucks, it's not the end of the world for us.

Peace and love, yours truly, soulcity

So your address still holds some fund? Since you can send a few sat, correct? Well I don't think there are any stupid "hackers" out there to leave anything behind., and you don't need to sign with segwit, since your public key is known, you could import your private key as legacy and sign the message.  But I guess it's life right? Acting so cool like it was a few cents. Good actor.😉

[coolcoinz]

Unless OP is an attention seeker and there was no hack
As they say in the bitcoin space, don't trust, verify.

If this story is real it's because OP was completely careless about his coins.
You can be careful, average or careless here and a careful person would have a hardware wallet or a multisig setup. Your average holder would have an offline device with at least one backup and an antivirus software. A careless person would have a desktop wallet with a password in a txt file, would hold the private key in a password manager and allow all his family to use the computer for movies, pirated software and all the other stuff they do.

[gunhell16]

Op's story also makes me think that, to be honest, 11 bitcoins is no longer considered a joke; it's a huge amount if I calculate it at the price it has right now.

If I ever have bitcoin, I will definitely split it into different hardware wallets. And I will hide the seed phrase in the variety of flash drives. But putting it in storage that is not really safe but that you thought was safe is a big mistake. And I can't even tell if you're telling the truth in your story, though my TXID record was shown to you.

But even so, you should have put your bitcoins in different non-custodial wallets so that at least if there is a problem with the wallets, there are other bitcoins hidden, so I am saddened by the loss of them to you. Maybe you should be careful next time, dude.

1. Anyone makes a mistake.

2. check this https://bitcoin.stackexchange.com/questions/51480/send-coins-with-electrum-from-encrypted-wallet-created-with-bitcoin-core
If you manage to import it you can sign the message.
or send the sats to me, it is a public address that is easy for everyone to verify.

3. Pray that the FBI catches them if they are from a country with extradition laws.

4. Report it to the antivirus, if you want to contribute.

5. Don't believe in bounty hunters, if it is already difficult to recover your coins when you forget parts of the seed, imagine the probability when you were hacked.

6. don't doubt your wife.

Cheer up!.
