OT: Read in this post about the wallet stealer. Even if this guy lost it that way or if someone else loose it like that. The hacker still needs the password doesn't he?

Of course, they need the passphrase.

However, if they dumped a keylogger onto the system, then the keylogger would be able to pick up the passphrase and redirect the logged keys to a remote PC and allow the person on that PC to then access the encrypted wallet and therefore they would be able to lift the keys from the wallet and drain the funds from those keys...

...the person who had funds at those keys would then lose their bitcoins because they would be moved to a new address by the person who managed to obtain a copy of the wallet and the passphrase. The other person would then control the coins from that point on.

You only need the private key to a bitcoin address to take the funds from that address. Since the private key allows one to spend the coins at that address, if you were to obtain the private key to another person's bitcoin address you would have to perform a transaction to your own bitcoin address in order to steal them (and of course keep it's corresponding private key - or else you couldn't access the coins yourself).

As already stated above, no keylogger was found after an indepth forensic audit of the machine used for that wallet. No malware either. And that same machine was used for other wallets as well, yet they were/are untouched and their coins still there. (they were all immediately resecured and liquidated for cash) And the machine was never used for browsing or anything else. It was a dedicated machine, on a dedicated isp connection whose singular purpose for bitcoin management. It did not travel, it did not connect to wifi connections in coffee shops...

you clearly are speaking without reading the entire thread. large amount of coins??? where did you get that idea? and further still, based on your false assumptions, what substantial thoughts do you have to offer? do some more reading about wallets and Bitcoin...? are you for real?

Last time I checked BTC22 was roughly worth about 10K USD, which I personally would consider a lot. Unless your telling me that your somehow some magical rich kid with no monetary concerns.

This statement is simply a clear example of your gross misunderstanding of how Bitcoin works. I've already explained 'wallet numbers' and your weird notion that companies hold all of the wallets. Of course I'm for 'real', I'm trying to educate you on how to stop this kind of crap from happening in the future.

you are a troll who imagines yourself knowledgeable about things you only observe but do not participate in. you have zero authority because you are a spectator, not a player.

you are like the fan in the stands who imagines himself an expert about the sport he is watching....

please go away....if 22 coins is your idea of "big money" you truly have no place in any discussion where real people are discussing real issues to do with bitcoins...go back to the porch where the puppies are playing and leave these matters to the big dogs.

Eh, in all probability it's just the normal FUD created by trolls who hope to change the price by scaring everyone out of Bitcoin.

@OP: Just because you lost your coins doesn't mean you have to try and ruin things for everyone else. Much better to use your time finding that security hole of yours.

please stop saying nothing and imagining you have anything of substance to say.

as with most of your comments, you offer nothing of value with your thoughts but use an arrogant tone that you imagine gives you the illusion of authority.

you've wasted plenty of everybody's time so far with your 250+ posts about nothing at all - how about giving the rest of us a break and taking your fingers off the keyboard.

No

And when I asked the blockchain support person to escalate this to security, he stopped communicating with me.

I was not a victim of phishing, I did not click on a fake blockchain link and there is/was no keylogger on my machine.

I believe a brute force attack occurred and blockchain is refusing to acknowledge it.

Can anybody help me track the movement of my stolen coins?

I know the wallet where they were sent to, and the other transactions that went to there too.

Thank you

A brute-force attack is rather unlikely if you had a password of reasonable entropy, length and complexity. It's far more likely you were using either a compromised system or you had your details phished. Tracking the coins is pointless, it won't be able to help you get them back. On a side note, your coins were probably sent to an address not a whole wallet and it's probable that no 'company' owns it, much rather someone running the standard client/Electrum/Multibit. Finally, even if it was a Blockchain wallet they would be unable to recover your coins because they do not have the private key. All in all, while I'm sorry for your loss, IMO you need to do some more reading about wallets and Bitcoin in general (especially if you're storing large amount of coins - look into a cold storage system) as you don't seem to understand how the system works and the best methods to protect your coins.

i know because my withdrawn coins did not appear in the blockchain 8 hours ago - so i opened a ticket with support and began asking friends to withdraw a small amount of coins as a test - 8 of them did - they are in 4 different countries - none of their withdrawals showed up in the blockchain either - and bitstamp support stopped responding...

if you don't believe me, try withdrawing even .2 btc and see what happens.

9 people have their withdrawals fail to appear in the blockchain and support does not say anything over an 8 hour period...?

after careful examination of my PC, no malware or keyloggers were detected.

I just had my blockchain.info wallet hacked, and my coins stolen.

Blockchain does not know how it happened and is investigating.

Here's what is known so far:

1) My identifier, pneumonic and password were all stored offline and separately.
2) My password was alphanumeric
3) They were never shared with anyone - EVER
4) I did not have my wallet setup so backups were sent to me by email
5) The wallet did not have an email address associated with it
6) Somehow, a hacker was able to gain access to my wallet and move my coins out - twice over 3 days (i did not realize what was happening and moved more coins into the wallet, which were moved out during a 2nd incursion)

I can see where the coins were sent to.

I know my tracing options are limited but I would like to try anyway.

How much can I learn from the address the coins were sent to?
Can I learn which company owns the wallet they were sent to? Blockchain? Bitstamp? Bitfog?

Actually you are both wrong. Yes the buying low and selling higher is standard arbitrage, but the manipulation that is occurring there is just that - manipulation! And as is the case in securities and currency trading, the kind of manipulation that is occurring at Virtex, would be illegal if bitcoins were traded on regulated exchanges.
What we are seeing here is the wild west aspect of an unregulated system like bitcoins. Things like this can happen and there is no overseeing authority to stop it. It isn't a free market, it is a manipulated one.
A network of people - say 15 - all work together to drive the price down so they can engage in an arbitrage scheme. Guy 1 puts .4 btc up for sale at a lower-than-the current-price rate - guy 2 buys it at that lower rate. Now that lower rate is the "default" rate for the whole exchange. Guy 3 and guy 4 do the same thing 10 minutes later - especially if the rate popped back up again by a trade that occurred outside their network.
This is textbook rate manipulation and is screwing over everyone else on that exchange. Right now, Virtex's rate is under $88 Canadian (equivalent to about $85 USD) but over at Bitstamp, their rate is over $95 USD. That's a 13% difference that makes no sense. The Canadian rate should be HIGHER than the USD rate because the USD is more valuable than the Canadian.
And saying the Canadian market is "different" than other markets is saying nothing at all. That kind of estimation of the situation was definitely not informed by an education in either securities, currency or financial systems.

Virtex is being manipulated by one of three entities: Virtex itself, a group of predatory traders or both!

For the past two weeks, the exchange rate (in Canadian dollars) has been $7-$8 USD below bitstamp, and $13-$15 USD below mtgox.

Aggravating this further is the fact that there is 4%-5% difference between the Canadian dollar and the USD.

So when Virtex is trading btc at $88 Canadian dollars, and bitstamp is trading at $95 USD, the difference, including the dollar to dollar exchange rate, is nearly $12 USD!

This makes Virtex the place to buy btc cheap and then sell them at bitstamp, mtgox or any other exchange for a quick flip profit.

An organized group is behind this scam, and it makes sense that Virtex itself, or a proxy of theirs, is the culprit.

Another scam that is 100% all Virtex is the fact that you cannot empty your wallet or your cash account to $0.00.

You must always leave behind some amount of btc, and some amount of $. This play is familiar to those who have been in the online gambling world. Usually something like 4 or 5 cents had to remain in your account at all times. It doesn't seem like much (and the way they explained it, it had to be that way or else the account will shut itself down) but when you add it up across thousands of customers, it becomes considerable.

I have asked Virtex about this point blank (3 weeks ago) and was promised an investigation but so far, nary an update has been provided.

Bitstamp has better fees and allows withdrawals to Canadian banks for a fee that, rolled in with everything else, still leads to a much better return than using Virtex.
