There gone.  Sorry but that is the reality.  Bitcoin was created to be irreversible like cash.

Your computer is probably infected. Format,reinstall OS and change passwords.

Use 2 factor authentication.

It's not Blockchain.info fault if your computer is infected or you didn't use 2factor.

All my blockchain info was encrypted on a memory stick that needed 2 passwords, the computer it was used on was soely for BTC it was clean as a whistle!

Every transation made will be to my ip, bar the one that just emptied my account on blockchain....

My blockchain account has been cleared today as well. 19.8 BTC.

I started using their Android app. I tried to log in today, and it failed numerous times. I tried again 10 minutes later, and discovered a recent new transaction had cleared the balance.

keylogger does make the most sense. run some type of AV, do a clean install, and try to think of what you've installed or clicked on to trigger a potential keylogger. you wont get the BTC back, but maybe you can start to make sense of it if you can piece if together

Would be interesting to know if "Strolen" was also using their android wallet. I'm quite scared of non market apps especially with rooted phones.

I'm really quite careful about what Android apps I install. I always check what access rights they want.  The phone is only 1 week old too.

I dont know if it coincidence or not, but I normally connect from the UK.  Today I am in California, and used a Net10 Sim card (AT&T).

Sorry to hear Sad  I'd still suspect that computer wasn't clean as a whistle.

I wonder if others have been effected, but dont know it yet.

I was actually sat on my blockchain acc and watched it happen, one min ive 39.70btc next min i went offline , so refreshed page and it said 0.00BTC.

then ive sat here all night watching where its gone!

I kinda hope others were hit too i might stand a slim chance of getting it back if was a few of us....

Looking at some the hops my btc been on others have been done aswell as clearly was more than my btc being moved by these accounts at the same time!

This is more than have took from me https://blockchain.info/address/1NeiLYQBFawaummF9XHc4hPBkG6W1bUCpb
Here you go whoever now has took https://blockchain.info/address/1NdJyQ5hUgLZMRU63VoWrb3KqGBGrV9yaV  No. Transactions    4    
Total Received    $ 13,918.55    
Final Balance    $ 13,918.55

so is defo others.....

I would always be wary of the apps you are running as well, especially if you are rooted. This coming from an android developer.

Honestly I hear about people getting robbed from Blockchain all the time - Two-factor auth when using google is not real two-factor, it's an illusion because if one password is compromised by an infected computer so is the other.

The solution is to STOP USING ONLINE WALLETS TO STORE VALUE - If you need to use them for transactional stuff, then do it but keeping 5000usd on blockchain is just screaming rob me.
