Did blockchain.info generate this key or was this a brain wallet?

If he got your backup wallet it's easy to import in electrum or blockchain.info https://blockchain.info/wallet/import-wallet and spend money.

but  main question is, how he hacked your mail?

Are you using some common/unsecure password or used same password on some other unknown/new website?

If you are using gmail, you can check ip address of recent logins.

I checked the ip address of recent logins.  Everything seems to be in order.

I don't have 2FA set in gmail, but my password is fairly strong.

So if it's not that, can it be some type of java browser exploit?

I am a big advocate of paper wallets.  I have never heard of anyone having a single bitcoin stolen from a paper wallet.  Print at bitaddress.org.

I am sorry to hear of your loss!
At this time, one theory is that someone got into my email and pulled the private key from a wallet backup file (possible, but not sure how likely that is).


its easy as shit to do, but he would have to know your blockchain.info account password, which he probably did if he was ablle to get into your account already.

just yesterday, i used an old wallet.aes.json backup to retrieve coins from my stolen laptop.

a little backstory: i made my first bitcoin wallet on blockchain.info, then exported the addresses to the bitcoin client on the laptop. the computer was stolen from my home last week. yesterday i found an old wallet back up and imported it into a new wallet at blockchain.info. it prompted me for the password to unencrypt the wallet, then for the secondary wallet password, then it asked me to prove i was human by solving a captcha, then bam i was at the login screeen ,where i logged into my new wallet and easily recovered the .4 btc that was in my bitcoin wallet on my laptop.

i'm sure the hacker did the exact same steps to steal your money.

Hi Mike,
I do have Armory set up on an unconnected ubuntu laptop, and watching-only wallets on my machines connected to the internet.

Yes, it's an annoyance to lose the coins, but what I'm concerned about is understanding how this happened, because I thought things were pretty buttoned up. 

The coins were literally sitting in the online wallet for just a few hours, as well.

Given that I had 2FA on, was running on a mac, was logged out of the blockchain wallet at the time....

At this time, one theory is that someone got into my email and pulled the private key from a wallet backup file (possible, but not sure how likely that is).

Willing to hear other theories.

I sent an email to [email protected] to get more info on the transaction.

2 Factor was on my cellphone.  I'm on a mac. 

Then there is no other way to steal coins except getting wallet backup from your mail.

Yes they can empty your wallet without doing login on blockchain.info wallet by importing your backup wallet into any client that supports it.

Ok, assuming they didn't get into my backup wallet file, what other security holes might I have?

Your pc might be infected. Download malwarebyets and scan it .
But still it's not easy to bypass 2factor authentication.

Ps: It was email based  2Factor authentication or device/cellphone based?

Email one is useless if your pc got infected or someone got your emails password.

Looks like someone got backup copy of your wallet, from your email.. maybe?

I do have the blockchain info wallet backup sent to my email.  Even if they had this, would they be able to extract the private keys?  I still had 2FA on.

It appears someone got into my blockchain.info account and transferred coins out of it just a few minutes ago.

I have 2 factor enabled.  Was logged into btct and bitfunder at the time (but not blockchain.info)

Any help would be appreciated.
