Topic: my computer got hacked and my BTC and LTC is gone what can be done (Read 2805 times)

If you can't use a cold wallet, use a hot wallet such as Electrum(with 2FA). If you think you can't secure your computer enough to secure your wallet, use a shared wallet such as GreenAddress. Don't use Blockchain.info. It is not a good wallet. It was removed from Bitcoin.org. Their wallet is very buggy and many users Bitcoins were stolen because of their mistakes. Move your coins from there.

no, it actually "is" the best option. as long as the cold wallet is created in a safe way and without any malware on the equipment that you use for creating it, it can be the best option.

paper wallet is hard to use because you have to sweep the keys and create a new paper wallet after usage to be ultimately safe.

but if you use an offline wallet and sign the transactions offline and broadcast it on another pc which is online , it can be easier to use.
i know of two wallets that do this so far (there might be more but i am not familiar with them) and those two are Electrum (which is SPV wallet) and Armory (which is full node) .

The whole point is it takes more to get to the wallet.  Cold storage works amazing if don RIGHT.    Is it as quick as leaving up a hot wallet? No

But is it worth the extra time to be safe ... yes!    And you can still keep a hot wallet just make sure to use cold for most of your assets.

im afraid that it can happen to me either, am i secure if i use blockchain wallet and i dont have any wallet files on my pc? i was thinking about cold wallet but i was too lazy to create it

No, it is not and cold wallet is a very safe way to store Bitcoin especially if you don't know how to secure your hot wallet.

advise to get a cold wallet isnt the best in my opinion how to transfer funds from cold wallet? Isnt it much harder than doing hit wallet transfers?

A lot can be done actually.   For one never keep a lot in hot wallets this solves a lot of problem's.  Cold wallets are where your wealth should be.

Also if you have a hot wallet don't surf stupid sites, open bad emails, etc.  If you do chances are eventually you lose some. 

Look into cold storage and encryption.

wise advice.

I dont think anything could be done if someone stolen it.

the only thing to get bitcoins back is to somehow find the computer that now has bitcoins and hack it back to get the wallet back and so on, though its nearly impossible to do

If they has taken your bitcoins nothing can be made. The bitcoins are lost. The transaction are irreversible.

What can be done?

Not a darn thing.... that is what.

These are the 'joys' of bitcoin being pseudononymous and transactions irreversible.

Happy days for criminals.

(I love bitcoin and the underlying tech but really.... some of the supposed 'benefits' I just really cannot see as net benefits for none-criminals at all)

There is not much you can do without legal intervention.  Depending on the means in which access was gained to your system, the attacker could have left traces if they were not careful.  Hopefully they did not use a proxy and their IP is logged somewhere in your access logs.

It's EASY to bypass antivirus. Especially if you are running 0-day virii. Antivirus can only catch things that are known and spread, so non-script kiddies generally aren't affected by them.

Indeed... But had you typed in your Wallet password ? or was your wallet.dat stolen ?

Also Which malware file you downloaded and where from ?

If the OP's wallet files had no or weak passwords then it would have been trivial to get the private keys. Another possibility is that the OP had entered his wallet password after his computer was infected with the malware on his both LTC and BTC wallets which would have caused the unencrypted wallet files to be temporarily stored in RAM while the wallet software is signing the transactions.

This is an example of why it is important to use a strong wallet password (that you do not store on your computer). If you do this and realize that your computer has been infected with malware then you can quickly recover your wallet from a backup on an alternate computer and spend your funds to another newly created wallet/address that was created on a computer not infected.

If you enter your wallet password on your wallet software after your computer is infected with malware then there is not very much you can do to prevent your money from being stolen. The only thing you can really do is change the settings on your wallet software so that it will store your unencrypted wallet keys in RAM for as little time as possible, this will force you to enter your password every time you spend funds in your wallet however it will give the malware a shorter amount of time to grab your private keys, most of the time this will not result in keeping your money safe, however it will with a very small subset of malware. Another thing this will do is protect you from physical theft of your computer because if your computer if physically taken from you shortly after you spend your Bitcoin then the attacker will likely not have access to your unencrypted private keys.

these threads always make me nervous :S i wish that OP would have added some more information about how exactly he lost the coins and what kind of wallet he was using.
from what i have read i think he might have been using a weak password for his wallet and the hacker might have brute forced the password of the two wallet files.

It's strange that they would've been able to steal both your BTC and LTC just like that. The email trap would have to be pretty sophisticated to achieve something like this. Did you confirm that it was indeed the email link that caused you to lose your coins? Did you consider other possibilities? Do other people have access to your computer?

You might had been Phished, now only one thing can be done. >>  <<
Good luck, Next time.

A tip for you, Just dont visit to sites which offers you unbelievable stuff or coins.
Visit trusted sites.

Did he ever identify the malware that cause this or maybe wallet he downloaded, i would like to know more about the method use to deliver the malware so we could all be more careful in our actions.

there is already a way to spend your btc offline, the problem is that many will find it troublesome, it need to be implement in a more accessible way, and it should be done with one click only, because we know that the majority are lazy, and want everything automatic
