I am sorry to hear of these transactions that you did not initiate. You may have some type of malware on your computer that resulted in your funds being stolen, because your private information was somehow obtained. There's also the possibility that you visited a phishing site posing as blockchain.info. By design, Blockchain.info never has access to users' accounts or bitcoins. If you keep your password and private key backups secure, then your bitcoins are safe with blockchain.info. There is also no way to reverse a bitcoin transaction. In the future, to ensure your account is protected with an extra layer of security, always enable two factor authentication. I would also highly advise against ever using this compromised wallet again, as someone else clearly has the private keys in it. I wish more could be done to get your funds back to you, but the nature of bitcoin makes it nearly impossible.

So, those who are keeping only the password and not the private key are insecure on blockchain.info ?

If you set up 2 factor auth and a second password you probably won't get your funds stolen. Also boot from Linux when you want to send money and you'll be much safer.

Just had some BTC stolen from this address. I used Chrome on Windows 7. Figured out what happened:

I googled "blockchain". The top result is a paid ad. This is what it said (sorry i am unable to cut and paste the image here):

  Blockchain - blockchain.info‎
  Adwww.blockchain.info/‎
  Official Blockchain website with wallet, charts, statistics and more

It then takes you to the following site: blockchain.info.wallet.georgia.ru which is a phishing site. I did not pay attention to the url when I logged in since the site looked legit.

Should had used 2FA and ALWAYS double check URL's.

You should always visit the URL directly (blockchain.info‎), since you know it. Searching on Google instead of visiting the URL directly makes it easy for anyone to send you to a phishing site, install a different software than the one you wanted (or together with adware+spyware)...

That site is hosted at 66.36.176.53 (http://whois.domaintools.com/66.36.176.53)

I don't understand why anyone uses IE, especially for $5k worth of bitcoins. You've got to spend some % of your bitcoin balance on security, at least spend $200 for a cold wallet laptop or something.

Different people. The OP didn't say which browser he is using.
I am the one that was using IE and I'm aware of the security faults. That is why I am switching to Firefox.

Probably the work of some hacker using a premium keylogger. The OP should have used 2FA, or at least should have enabled the email confirmation using Gmail or any other reliable mail service.

What browser and plugins are you using? Since Mandrik said it could be due to a third party plugin, knowing this could certainly help.

I'm using IE.
Though I am making the switch to Firefox.

Don't know of any plugins

Same thing happened to me, but my account was just about empty, so I didn't care.
When I logged in to my blockchain wallet, it sent the last of my btc to: 1894H2A9oWL9uFJY6E1yt5MUXByqWqqY9z
I didn't initiate anything.
I'm just not going to use this wallet anymore.

Edit: do not use same password as any other anything of mine.

Mandrik from Blockchain.info here. I'm seeing a number of users reporting funds stolen from them & sent to the 1LQQkqtWWruiofuD8jkMHxD5jMdKk7Vuh6 address. I'm wondering if this has to do with a third party plugin or app currently being used in a browser, much like we saw a few days ago. If you have any information on this please shoot me a PM. I'd love to be able to provide more information, and also warn others. Thanks!

no,no.and no!

You should have enabled 2FA. Though it won't provide 100% safety, it still provides another safety measure to your bitcoin.

Have you enabled 2FA?
Have you received some phishing emails and clicked the link?
Have you download some "strange" programs which may contain keylogger?
