Hm, I just downloaded the the DOGE-Coin wallet and right after the BTC were stolen. But I downloaded it from the official site. Seems very strange to me.

I already changed my payout address on the pool and will delete it later when all the BTC arrived.

First, the thief took all the BTC in my wallet. This was the transaction:
https://blockchain.info/tx/d6c75c6914c598d19fd6c0f73da0b009786e6585c57c6023ffbebdd6d7d0fecf

I used the Bitcoin-QT wallet, but I used it without any password protection. Could that be the entering gate of the thief? The thing is that the machine is a newly installed windows and I did not download anything special to it.

As a consequence, I opened an online wallet on blockchain.info with mobile 2FA and including all the security options they provide. I imported the old private key from Bitcoin-QT, where my miner sent some minor BTC:
https://blockchain.info/tx/fee2c98ead5078127b3cbb8812332f1fa110f7326d65f0f577fa0e6ee38fe861

Can this cause any risk to the new private key of the new BTC address? I will wait another week and the I delete this address from this wallet since my miner has still some immature BTC.

Thx for your advise and best regards

No, running bitcoin core does not make you vulnerable. No matter if your wallet is encrypted or not.

Importing a compromised private key is a bad idea. Someone else also has that key, using it is not advised. Change the payout address on your pool.

The compromised private key can not compromise any other keys in your new wallet.

Finally: what do you consider "nothing special"? Some Altcoin wallets have trojans in them...

Hi guys,

I used bitcoin-qt as my bitcoin wallet and I forgot to setup a password Sad

So today I checked my wallet and a very small amount of bitcoins were stolen:

https://blockchain.info/de/address/1CPEdjFu6TaZpPFGQ81zHaW7prtJ1pk8LV

Is there any chance I get these BTC back? Or do I have to pay to learn the lesson?

After that, I moved to multibit and saved it on several USB-Sticks with a strong password using KeyPass obfuscating. Is there anything else I have to take care of?

Thx for your help!

Regards

You allready paid the lession, and no u cant get those bitcoins back.
You probably picked up trojan, and your password was taken from built-in keylogger that comes with it.

Best thing u can do now is make a clean install of OS, and make a new wallet, be advised that sending coins to that compromised address/wallet wil probably make you loose more bitcoins.

cheers

did he take the whole amount or just some?

From the blockchain.info link in OP, it seems the thief has stolen 0.145 btc and has left 0.00055266 BTC in the address.

Mix it and send to a complete different address stored on a USB stick. There is no way you will get your money back unless the thief sends it back for some reason.

Mixing it doesn't improve the security, mixing only increase the privacy. OP, I suggest you to create a cold storage paper wallet using a offline linux computer and bitaddress.org.

Learn about cold storage, too. And do format or just scan your computer, you definitely have malware there...
Be careful what you download, internet is a dark place

This is the first thing I'm trying to learn, I don't have much btc money but cold storage seems to be a must read here.

Hm, I did not download anything suspicious. The pc is a computer with a newly installed windows on it. I think the main mistake was that I did not set a password on my BTC wallet. I think the program should force you to use a password, but nevermind. Thx for the replies!

The question still stands: how did the attacker get your wallet.dat file. Unprotected or not it still has to leave your computer in order to spend your coins. The encryption is an added security feature, but files should not just leave your computer and end up somewhere else.

I am sorry for your loss, but I am afraid there is no way you can get it back. Sad

Don't go to some strange websites.
Don't click strange links.
Don't download strange email attachments and files.

Switch to an offline wallet when one day you have a significant amount of bitcoin.

Whatever happened to that hardware wallet that was suppose to be shipping about a year ago or so?

You mean the Trezor?
If that is the case, it is coming really soon.

So how long to wait YET?
As promised, all Classics will be shipped before the end of this month. During next week the entire First Edition batch will be finished. Then packages sorted, put in envelopes with Certificates of Ownership, sealed with much love and gradually sent out to you across the globe.

Sorry your bitcoin was stolen. Small amounts are easier to store at the places mentioned above. For large amounts it really is worth your time to do a paper wallet.

My suggestion is to not use Microsoft Windows and to use GNU/Linux instead, and yes encrypt your wallet. If one originally created the wallet on Microsoft Windows move the coins to a new wallet created on GNU/Linux. I have been involved with Bitcoin since 2011 and have not lost a single satoshi to malware; however I would not let a single of my satoshi near Microsoft Windows. Make sure to make multiple redundant backups of wallet.dat and keep in mind that after 100 transactions the change or received funds are no longer backed up when using Bitcoin-qt. A good habit is to back up wallet.dat after 20 transactions or so.

By the way I stopped using Microsoft Windows for fiat banking back in 2006 before Bitcoin even existed for the same reasons.

I'm not really impressed w/ these stories popping up about certain cold storage options getting people hacked or stolen. It's almost easier and safer to leave them at Blockchain.info w/ 2FA on or vault them w/ Xapo.

I think that the blockchain.info wallet with 2FA is a mighty fine idea for those wanting to store small holdings of bitcoins. There are so many stories being posted on here of people having their wallet looted, sometimes due to no password, sometimes keyloggers, sometimes even by those close to you.

There's no realistic way to get your money back, DrRobotto. The most likely scenario is that the thief will send some or all of the BTC back to you - and that's unlikely given that they committed the crime with intent. Thankfully it wasn't considerably more - you will have to use it as a lesson.

This will not happen if you have a clean pc!! Stop downloading crap and you will not have this problem anymore. Do a full system scan with up2date antivirus.
