whats your suggestion ?! do u advise me to send all my BTC to my coinbase account ?
please need help for this problem before they stole my BTC


this IP tried 2 times


this IP too tried two times


Regards!

If your passwords are strong and you have SMS verification and email verification enabled, then you should be safe. As long as they can't guess your password and get into your account, then your Bitcoin is safe. You could also enable IP whitelisting and only allow connections to the whitelisted address, but this can be problematic if you have a dynamic ip address.

thank you so much for your reply

i really have strong main password and second password more than 10 character
yes i have dynamic address ip  scared if i add Whitelist ips and cant login again
cuz sometime i get Ip for example 100.200.1.1   and sometimes i get 200.50.1.1

How this hacker knew your blockchain wallet identifier !
To be sure your bitcoin are secure, I recommend you to create another wallet and send all your btc to it and apply 2fa

that is the real problem !! how they know my wallet identifier  ???



if they really know my identifier wallet , really its bad idea to move BTC to another address in same account
what's ur think about coinbase ! its safe ?

Coinbase is fine, I used it for months without any problems.
You can use any wallet you want it will be safer that that blockchain web wallet that is under attack by that hacker

thank you friends i appreciate it now i'm going to move my BTC to coinbase and e-coin
cuz already have e-coin i'm stored some BTC thier

Best solution is to move your bitcoin to another wallet, i recommend bitcoin core or electrum.
If you want to use coinbase then it is fine too with the advantage of free transactions up to 25/day but you don't have control of your private keys

if you are going to move your bitcoins i suggest not to move them to online websites, it is better to you desktop wallets for you to have full control over your private keys and funds

It's important to recognize that hot wallets are good for small amount's.   It's different for everyone but it' spending cash is what they are good for.  You don't want long term holdings.

If doing long term look into cold storage or hardware wallets.  Either one is better then a hot wallet someone is trying to break into.

if is device is infected, it will not change much, actually it make his coins even more vulnerable, because there will be no more 2fa with google

scan your PC for malware and any kinds of keylogger. If there isn't, you should try to reinstall your OS to make sure than switch to use electrum or bitcoincore,...

yes i move some BTC to e-coin and coinbase just hope will not get attack again in this wallets  ;D




i agree with you but i have too slow internet connection and the desktop wallets need good internet connection to be updates with blocks 

i have kaspersky paid version but didnt find any malware or viruses maybe this antivirus cant find them if really in my computer !!
i'm using windows 8 it new for me when i chek " Gestionaire des taches " i'm seeing many programs runing like UIExec32, Dynamiclinkmediaserver.exe, CancelAutoPlay_byt ( 32 bits ), srvany ( KM services ) .....

are this programs legit and safe ?

The good thing is you have phone or 2fa on.  Honestly that might have saved you.  Are those different than your IP?   (I'm guessing so).

If they are different they might now have access to your PC, but somehow got login.  Do you log in at any public WIFI, or somewhere not at home? Or do you surf/download any "bad" sites?

If you use the password for anything else I would change it on a computer you know is secure, so they cant get anything.  And I would change password to hot wallet aswell.  But again the part about being a safe and not compromised computer is key or your doing it all and it could be for nothing.

keep a 2 factor auth for blockxhain, I am pretty sure they have , and once BTC lost cant be recovered so be careful

You have a keylogger in your computer, reinstall your system asap and change all your passwords

The same happened to me as since past few days, I am also getting emails to my id asking to put in that code to login as I have enabled 2FA for my account...

I just formatted my laptop and everything is fine now...

Bloclchain security is just a big pile of joke
It's really easy to hack since they have lots of securoty vulnuberality (not sure if i spelled that right)
I used to own coins on blockchain with secondary password and 2FA
Guess what
THEY MANAGED TO BYPASS THE 2FA
They took few of my coins that way :(
Anyway, i now using desktop wallet which work flawlessly ;)

It sounds like your computer is defected with some viruses or trojans. So first, move all your btc to another wallet and I recommend you to use mycelium wallet if you have an android device.
Secondly, format your PC and install a pure , clean operation system.

Dont worry about your coinbase account its safe and you cant hack by hackers by sms verification enabled
You can add your ip as whitelist just choose all ip for your country and after that well than all your funds will safe..
You can try also the vault of your coinbase account with two email verification and one sms verification then if you withdraw in vault
2 days process before you recieve a withdrawn bitcoins from vault after verified it..
this is safe for me.. I think you are monitored by hackers via cookies so i think you need to clear all your browser cookies and make sure
to delete all your cookies you can try ccleaner and make sure you have install licenced anti virus and updated to prevent malware and virus
To get your personal information or keylogs..

how did you know that ? how can i find the keylogger ?! i have kaspersky paid version scanned my laptop didnt find anything
there are only one problem in my laptop i cant update it sometimes i configure it i lost connection some times i get error with HTTPS cant login to google , bitcointalk .....   


yup thinking to format my laptop too,  one problem " i have lot of works in my laptop " such as PSD banners project dessign in localhost .....

thanks for advise will test mycelium wallet in my android phone


sorry for your lost bro
already activate second password  mean when i want to send some BTC i need to put second password
cant use desktop wallet at this time bcz i have very slow internet
but if i really have trojan in my laptop he can stole my wallet.dat no ?!

already move some BTC to my coinbase , Vault is great idea if you plan to store some BTC to use them in the future
about cookies i clear them time to time and i have paid version kaspersky 15.0.0.463

i appreciate all of your replies brothers u really helped me to be safe from this hacker
