Hello, the Computer is clean, was used only 2 times when creating a wallet and when transferring to the wallet. Then immediately was turned off and lay off and without access to the network and the Internet. Passwords and key phrases were stored in a safe, access to them was not. There was a 2-factor authorization on the wallet, but no requests were received! Anti-virus protection was. What to do in this case. Transaction ID: b2ca903ecc76ad18b75c475d33561770f5c0cb740b5a39eab647eed1cbad3390

How did you crack the wallet? what tools did you use? can I have the tools/method?

I didn't hack, my wallet was hacked. To know who and how, here would not write.

this outgoing transaction (https://www.blockchain.com/btc/tx/b2ca903ecc76ad18b75c475d33561770f5c0cb740b5a39eab647eed1cbad3390) was done 4 months ago (2018-06-09)
then there are 2 more incoming transactions before another outgoing transaction
and this second outgoing transaction (2018-08-26) was done 19 days after the last incoming transaction

everything looks normal to me, it's unclear what you're trying to say...
which one is actually your address?

edit: it seems 1LuPmN4GGtvsW8X49EtKf1Ekx4JRKEGChr is your address, correct?
the transaction was 4 months ago, why you just ask now?
can you tell me what wallet you're using and a bit more of the story behind this

It is not core looks like it could be blockchain.info

For the 2FA i deduct you were using blockchain.com wallet... if that was the scenario you should get a mail while the hacker uses the data from "Passwords and key phrases were stored in a safe", but still weird because if they had access to the safe then how they get the 2FA.

And here is the other option when you created the wallet someone copies it, you say the computer was clean, but I know some nice AV Bypass, so, is hard to know when a PC is really clean.

Option C... a cracker found your private key by luck. The chance of this is 0.00000001% or less, but it has a chance.

So, think about this 3 options. I can't imagine another scenario.

where did you download your wallet?

There are many fake wallets and fake web pages that look like the real ones in the net. Creating a private key with any of them will lead to a disaster.

We need more information to help reconstructing what happened. Please answer these questions:

• What OS are you using ?
• What wallet did you use ?
• Where did you download the wallet from ?
• Did you verify the downloaded wallet ? If so, how ?
• What kind of 2FA did you use ? (e.g. RSASecureID, GA-app on your mobile, ... )

This is the information we need at least. The key element would be the wallet used and the verification of the wallet.

OP already lost his bitcoin because someone hacked and stole his bitcoin.  Instead of being sympathetic you are making fun of him.  I think it is not human behavior.
If we can not co operate / help someone; we must must not make fun of them. 

Think if we are treated like this under the same circumstances, we will not be feeling good.

I don't think they were making fun of the OP... it is a simple case of misunderstanding due to language issues.

The OP has set the thread title as: "Cracked the wallet and stole the BTC". Because of the word tense used, it implies that the OP "cracked the wallet" and that the OP "stole the BTC". Based on the other grammatical quirks in the OPs posts, I'd say it was a bad "Google translate" or similar. The thread title should have been:

"My wallet was cracked and my BTC was stolen"


In any case, as we all know, once the coins are gone... they're gone. Your chances of ever finding the culprits are fairly slim... and as bob123 has pointed out, without the appropriate information, no-one here will be able to provide any answers... a transaction ID is not enough.

I agree I can't understand what's happening here I was dragged here because of the title.

Could be someone has access to his email address. But if its 2FA, is it going to prompt only the email? Or maybe he doesn't have the mobile number configured on that wallet.

It's a bit of, an offline wallet or a online hot wallet in my head.

How come those people above are making fun of OP? Have you even read up on the things they do post or suggest? If not then better read it again
yet i havent seen anything wrong with those words and in fact i do have the same questions above.It should have been elaborated even more on what wallet he did use up.Its impossible for a
wallet to be cracked up if keys arent exposed but as i have read it do have 2fa so most likely this would be a web-wallet.

recently I have create a wallet on blockchain.com.
after creation, I have given my wallet ID and password to my friend located in USA to check if everything is ok.
after he check for me, I have change my password and enable 2FA and backup phase which consist of the 12 words.
my question is, will he able to log in my account even after I have make the above changes?

This is not recommended. You should NEVER give anyone access to your coins.

Your friend could have also exported the backup phrase (the 12 word mnemonic seed).
This seed is everything one needs to access the coins.

I'd recommend to create a new wallet immediately !

If you insist on using an online wallet, create a new one and send your funds over.
If you don't explicitely want to use an online wallet, get a desktop wallet (e.g. electrum (https://electrum.org/#home)). Those are more secure and safer.

But you definitely shouldn't be keeping any coins inside of this wallet anymore.

he won't need to log into your account to get access to your bitcoin
as bob123 said, he could've copied your backup phrase, hence your wallet has been compromised 
if this is related to your posting about "blockchain.com mining setup"... that mining is a SCAM

What wallet was it as that doesn't sound to be like Bitcoin Core to me as if the wallet was offline no one could touch it. Period.
