BTC theft in blockchain

[Bunkaz91]

Ok so heres the transaction:https://blockchain.info/address/13KTtSy1pBjif5FHMa8evQsGv54K2xaH4P

So I sent Bitcoin from 13KTtSy1pBjif5FHMa8evQsGv54K2xaH4P to the address 1DkYaLNdZwR4SRWX3qEsMmu473nXuAUccy

The fee was low and it took over three days to confirm. I woke this morning and checked my electrum wallet to see that the transactions had been confirmed. Hooray!

No, because when i checked the receiving account the balance was 0.

When i checked the blockchain; https://blockchain.info/address/13KTtSy1pBjif5FHMa8evQsGv54K2xaH4P

It shows the main output of the transaction (my btc) as spent to a random address and the miners fee unspent.

Can anyone help? The target account for the BTC was 1DkYaLNdZwR4SRWX3qEsMmu473nXuAUccy

There is no way for anyone to spent your bitcoins unless your wallet password is compromised which in turn means your machine has been compromised, probably with malware, are you sure you did not accidentally sent this tx https://blockchain.info/tx/995591fc0a407c52c6b8e791dd6e095d237e1e1dad2673e0c2f25e6e43aabe87 to 1LvKgYwaoemuUiGyueTAHJFQrRtJyJe4qB, the particular tx was sent with super high fees too, probably malware.

Hey thanks for the fast reply! No the address ending UccY was definitely the last output I made. Is there anyway to recover these coins or have I been beaten? Im using mac, how would i go about removing any malware? Also if the coins successfully went from my wallet to the uccY wallet successfully doesnt it mean the UccY destination contains the malware?

Is there any other possibilities other than malware? I would be extremely surprised if the final wallet destination was attacked with malware although it is possible

You say you sent ~0.128 btc from 13KTtSy1pBjif5FHMa8evQsGv54K2xaH4P to 1DkYaLNdZwR4SRWX3qEsMmu473nXuAUccy using transaction:
https://blockchain.info/tx/d30332d7cd1c4136baa54e300c8dbeb5651ef07fc9cba4f1bf853285e2a1a803

That is all confirmed and everything worked as it should. If 1DkYaLNdZwR4SRWX3qEsMmu473nXuAUccy is not your address, but belongs to someone else... in a different wallet, on a different computer... then they are the ones with a problem. The coins were spent from THAT address, so if that address isn't yours, you are not the one with the problem.

If that address IS yours... then yes, you do have a problem if you didn't send the coins to 1LvKgYwaoemuUiGyueTAHJFQrRtJyJe4qB in transaction:

You only need the private key to spend the coins. Paper wallets don't have passwords

Oh damn.. I read op's first thread comment and interpreted it as that he owns the private key to address 1DkYaLNdZwR4SRWX3qEsMmu473nXuAUccy.

OP, if you merely sent intended to send bitcoins to address 1DkYaLNdZwR4SRWX3qEsMmu473nXuAUccy  as a one time payment, and you do not own the address, HCP is right, you have nothing to worry as your payment was indeed received by its intended target.

However, if you mean that you own address 1DkYaLNdZwR4SRWX3qEsMmu473nXuAUccy but the payment sent to 1LvKgYwaoemuUiGyueTAHJFQrRtJyJe4qB was not done by you, you do have a problem.

I do hope that I misinterpreted your original statement and that your case is the first one, in which you have nothing to worry about, in which case I offer my apologies.

I was assuming that op was using a mnemonic phrase along with a password inside electrum
