How is this possible

[Lorenzo]

My bitcoin wallet was hacked again even protected by 2FA google authenticator and secondary password. Anyway i created a new wallet, but how is this possible

mitm,  they are simply hijacking your logged in session and taking your money.

Are you using a web wallet?  You shouldn't be doing that - they likely have your saved session data.

Use a paper wallet that was generated from a computer that is offline...print it, then make sure any memory is not stored in the printer.

If that doesn't help then consider that there may be an inside job happening where you do bitcoin business and your machine is compromised.

[sarcasm] what kind of king of btc gets consistently jacked like this? [/sarcasm]

Would a MITM attack be visible in the logs? Would the login be shown as coming from your own IP address or from another IP address?

why people still store on online wallet, is behind me, my advice:

buy a old laptop, and leave your wallet there, use that laptop just for that nothing else, like if it was your bank

a hw-wallet like trezor or any similar one is the best solution i think.. This would also remove the risk of malware, keyloggers, etc. And might even be cheaper than an old laptop.

i recommend the Trezor "wallet" from slushs company satoshilabs.com. (www.buytrezor.com) - heres an interesting review: http://www.coindesk.com/review-bitcoin-vault-trezor-lives-name/

heres a nice overview on all the hardware-wallets for btc:

Yeah it's impossible (or very unlikely) that the reason is anything else but some sort of keylogger/malware, your defense was strong enough pass wise but not OS wise.

[mitus-2]

again? sorry for your losses but consider that your fault. first of all never trust an online wallet service such as blockchain.info
secondly, from now on, you can use an old laptop disconnected from internet as a secure place to store you coin. otherwise you can download and execute a live version of Tails OS to create an offline wallet with Electrum

Not again, only 2 times max, now i have email 2fa and so far nothing is stolen from my blockchain wallet after doing this. still i am better with the Multibit in Ubuntu. I added a password to it for added security. Its sitting in my desktop.

Attacker might get your private keys by keylogging or by sidejacking (it'll happened when you used public Wifi)

[kingofbitcoin]

Its in my desktop at home, no WIFI, only LAN connecting, i know this can be hacked too, but is much more difficult then Blockchain and at least is a software, attacker need to have access to my desktop. I keep this in my home PC, not in my office PC.

add some anvirus protection and key-stroke protection like zemana anti-keylogger, they help alot against malware and other stuff

Using Ubuntu Linux is probably a good idea. It may be worth having a dedicated machine just for holding your wallets.

Best idea is to have an offline laptop to store the coins.

Learn to use electrum. At least even though a thin client, you HAVE YOUR OWN PRIVATE KEYS

[tadakaluri]

Once your username and password are known to a snooper, they can access your precious bitcoins, whether the credentials are for an online exchange account, an online wallet, your mobile wallet or your PC wallet. If your PC or mobile is connected to the internet, an attacker can access it using security vulnerabilities specific to the device’s OS.

If, like most people, you use a password formula for various logins then you should consider strengthening your passphrase scheme (formula) to generate more secure passwords. Often, the theft of one of your password can reveal all of your other login passwords, because they are variations of a formula. Botnets exist to decypher and extrapolate these formulaic passwords.

A standard Bitcoin transaction requires your private key to unlock its bitcoin outputs. If a third party obtains one or more of your private keys (stored in your wallet) then, he can transact any coins previously received by that public-private key pair. Such a transaction doesn’t have to be made using your wallet – it can be initiated on any device and from anywhere. This is a design feature of Bitcoin which allows, amongst other things, the ability to import and export addresses between wallets.

The following infographic can explain more about it:

Your infographic has several incorrect "facts".

Additionally, it has some "statistics" that are likely to be misleading.

i really don't understand why people are posting that stuff [err infographics]. Its neither clarifying anything nor helping the OP to get his btc back or giving him an idea of how to secure his enviroment for future btc-traffic/handling . I just can repeat myself again and again: Your BTCs are as safe as your computer is. Means: Your wallet is an open safe as long as your computer isn't secured properly.

lets put this "diplomatic expression stlye" aside and become "lil bit" straighter:

short form: "That infographic is sh**y and overloading this thread because its containing incorrect "facts" (for example mtgox hack alone was +500m in 2014-exrate) as well as being short of +50%..." delete that mess. i think OP s got enough sh** around atm. and might also have too much sh** in his head. read the rest of this post to understand what i actually mean.

@OP: just read your below post.

Mate i am Muslim just to let you know, i don't watch porn let alone download it. So your sense of humour is wrong in here, although i like humour very much.

[snip]

The Middle East already has the world's most popular porn star ­— 21-year-old Mia Khalifa from Lebanon.

[snip]

Just wanted to say i am not from any of these countries ,lol, i am from Albania, i know a lot of my co citizens watch porn, but i really don't.  If i will do i have kept the list site which not to visit from your post.

And honestly if that Khalifa something you re talking, i hope someone cut her head off , i mean it really, shame of the Muslims if she is who you says.

Are you serious? So you want someone to cut her head off?? Or put it like that: You HOPE someone does it??

something else. I haven't found any BTC key or so in your first post. Can you please post the btc-key which you claim your coins "got stolen" from?
