90 BTC stolen!

[coinrevo]

Now I just want to know how the wallet summary can show a double-direction arrow and a n/a address?
Doesn't that obviously indicate that the transaction is invalid and so it should be reversed by the system?

nope, sorry. transaction went through (250 confirms). the arrows are a feature of the wallet, and has nothing to do with the system itself.

And the wallet was not emptied, with more than 100 BTC left not taken, Weird!

Could it be that you just sent the coins to yourself / between two wallets?
Anyway, if you have 100 coins get them off your computer NOW, and investigate later.

[philipzhai]

I already send out my BTC left. Thank you.

I need your help!

I have 2 bitcoin-qt wallets, and yestarday one single transaction happened to both of my wallets and my 90 some BTCs were transferred out of my wallets. I don't know what happened and if it's possible to recover. The blockchain information is as follows:

https://blockchain.info/tx/32d070a547e9d2cc2de4dc453cea27789bf33f1c983ffdc7f28ce3419e70c9d5

On my wallet client software, in the transaction record column, the "address" shows a n/a, and the summary shows a double direction arrow.

How can two wallets be made to transact at the same time with a single transaction? The two addresses are as follows:

1CLn42dHFuXAd7o9bgrsCRmfDvLavRoxTq
1H4esgi6KwhDtVXZXJ12AS7QEwdeQighn4


Is it possible to track down the thief and recover my lost?

Sorry to hear your loss.

Have your wallets been encrypted?
Have you stored some unencrypted backups somewhere online (emails / dropbox / etc)?

[philipzhai]

My wallets are all encrypted.

[Sonny]

Maybe the password is too simple, or you have a keylogger
Sorry I can't help much here...

for anyone else concerned about losing their money I highly recommend the following free way to secure your wallet.

1) Install True Crypt on your PC/laptop and create an encrypted volume that is only mounted manually.
2) Install Virtual Box.
3) Create A Linux virtual machine inside the encrypted volume using a clean install of a popular distro (xubuntu etc)   (I tried ubuntu but its a bitch to get working with Virtual box)
4) Install Armoury, Bitcoin Client, Litecoin etc into the linux virtual machine (whatever trusted wallets you want)
5) Create your encrypted/password protected armory, litecoin and other wallets inside the virtual machine.
6) do not use the virtual machine for anything other than Sending and receiving crypto transactions, do not install anything other than the bare essential tools you need and do not surf the internet with it.

from inside the virtual machine you should also be able to create a paper wallet for cold storage.

NOTE: you will need about 80gb of space if you want to store the entire bitcoin and litecoin blockchains inside a virtual machine.
when you are not using the virtual machine you can pause it (remembering to always Pause when the screen is locked) and dismount the encrypted volume.

if you want to back up all your money all you need to do is copy the encrypted volume to another PC or external HD and  locate the backup far away from your PC (failsafe incase of fire/robbery etc)

this is the most secure way that I have found to protect your Coins while keeping them fairly accessible and safely backed up.

all the tools above are FREE. it only takes your time to learn how to use them properly.

and if you think its too much effort.. I would suggest that its probably not too much effort to secure a few thousand dollars worth of BTC which could be worth 10X that in the coming years.

Also if the address 1H4esgi6KwhDtVXZXJ12AS7QEwdeQighn4 is compromised (or the wallet.dat containing this address) you should reroute regular 0.03 BTC payments (are these mining profits?) this address is receiving somewhere else.

making cold storage easy should be a goal => building a custom linux distro + raspberry PI + printer.

Is it possible to track down the thief and recover my lost?

sorry for your loss, but playing law enforcement is not a good idea.

Exactly!  Even if people do see warnings online to use an offline wallet (which many do not), that sure as hell doesn't mean they know how to do it correctly.  And I'm sure the rebuttal will be: "well if they can't do that they shouldn't be using bitcoin."  Which is a great response - if you want to repress the expansion of bitcoin.  

I agree! The use of Bitcoin must be made foolproof! We can't expect the general public to embrace it if the process of safely storing your money is so damn USER-UNFRIENDLY!

Android qt relied blindly on the java "secure" random function and money was lost. Maybe something similar happened here.

labcoin shareholders have been hunting for 7000 BTC for many months.. its not easy to trace the money if the thief knows what they are doing.

Starting from that address, which has now a balance of 0 BTC, if you follow all the transactions involving the money, you will go through numerous addresses which in turn sent the whole amount (thus remaining with a 0 balance) to the next one. Why is that?

@ OP: why did you wait almost 2 days to report the theft?

[philipzhai]

The thief kept moving BTC around to avoid being caught?

I see. Bitcoin qt never had this problem.

the money is actually going down bcos they are spending it... spent coins are even harder to trace...

theres only 48 BTC left
