I have located a suspect, his name is 陈建海(Chen Jianhai). He's NOT my friend and we have never met in person. He was one of my previous business associates because he's very familiar with credit card fraud and he advised me a lot (in terms of fraud prevention, of course) when I built my virtual goods payment processor in late 2010.

He has knowledge of my secret gmail address and I have once re-used the password in his web shop

His English is not very proficient and I'm sure that he's not reading this forum at the moment. I'm giving him a call now to persuade him to admit his wrong-doing and return the funds.

I'll post another thread soon.

I was one of the first to predict that zhoutong had taken the money in an inside job.

I'm now going to predict that he'll discover his "acquaintance" took the money and it will be returned shortly.   Undecided

And I predict there will still be people that think he is innocent in all this...

Already did.

ZT,

So a hacker compromised this gmail account of yours?
How long ago did you notice someone else was using the email account?
You said you saw credit card fraud that used this email account, how long ago was that?
Why did you not contact services that this email account was used for to inform them?
where else was this email account even known?  
Who knew you used this email account for anything?

I would really like a better timeline on this email account..??

anyone?

If you're not excited by the idea of being an early adopter 'now', then you should come back in three or four years and either tell us "Told you it'd never work!" or join what should, by then, be a much more stable and easier-to-use system. - GA
It is being worked on by smart people. -DamienBlack

Is this an accurate timeline?

ZhouTong builds a valuable commodity, which transacts large quantities of pseudo-money.
Security conscious users probe the Bitcoinica system and find it vulnerable.
ZhouTong was warned about some weaknesses but defends his design decissions instead of looking to improve security.
Bitcoinica is cracked and a large amount of funds are moved out of Bitcoinica.
Dust settles then Bitcoinica's MtGox account gets cracked.
2 exchanges and 1 uninvolved company partner up and provide suggestive accusations which point at ZhouTong as the culprit.
Still, nobody mentions where the coins travel or sit.

The attack could have been carried out without ZhouTong being aware that a compromise had occurred. It's possible an attacker had unnoticed access for a long period of time in order to collect information and to plan the theft. If the attack occured without ZhouTong having been a colaberator in the heist, then a large group of people are spending a lot of time pointing a finger in his direction. So far we have only seen a lot of hype and only one flimsey connection of ZhouTong's involvement. The information was presented in order to frame ZhouTong in a suggestive manner which portrays him as a criminal. You are trying cases in the court of public opinion, this is very unprofessional even if it weren't slanderous.

Did the current owners of Bitcoinica do a security audit before they got financially involved in the company?

For Bitcoin to be a true global currency the value of BTC needs always to rise.
If BTC became the global currency & money supply = 100 Trillion then ⊅1.00 BTC = $4,761,904.76.

Flimsy? Zhou Tong admits it was his email and is just stating it was a compromised account. The exchanges are in a serious bind since they deal with government currencies, they can't be seen to be aiding in theft or laundering. Might want to ask Intersango what the consequences can be for an exchange.

* The Liberty Reserve account used by the hacker is U9236056.
* The email address used by the hacker was stevejobs807@gmail.com.
* To my surprise, upon further examination of our order system, I found an order from Zhou Tong to sell Liberty Reserve to us for the amount of USD 40,000, requesting a wire to his bank account in Singapore. The amount for the order closely matches the total USD exchanged through us (after fees) using the MtGox USD codes stolen from the Bitcoinica account.
* This order was placed the next day the hacking attempts occurred. In addition, it should be noted that Zhou Tong has never dealt with us before as an exchange customer.
* This information was immediately sent to our two biggest trusted business partners: MtGox and Bitinstant in an effort to join forces to further investigate this situation.
* Mark Karpeles indicated that there was an account opened at MtGox using the email stevejobs807@gmail.com sometime in 2011.
* Mark replied stating that there was activity on this account, that the account was opened using an IP address belonging to Microsoft Singapore, that Zhou Tong was known to have worked for said company at said location, that the email stevejobs807@gmail.com have been verified, and that ALL activity on this account is linked to the MtGox account belonging to Zhou Tong.
* Mark has also indicated that the very first operation on the MtGox account opened with email stevejobs807@gmail.com was the redeeming of a 10 BTC MtGox code generated from Zhou Tong's account.
* Charlie indicated that Erik Vorhees (a well known member of this community) has emails he exchanged with Zhou using the email address stevejobs807@gmail.com.


stevejobs807@gmail.com was indeed my email account used for anonymous testing purpose, however I haven't been using it for a long time. I'm logging in the account to check the suspicious activity and I'll post relevant details as well.

The email account had a heavily-reused password (for the sites that I don't intend to share any private data), *at least* it was used on LinkedIn and many other websites.

The email account is only used for testing purposes, has a heavily reused password and is used at sites that you don't plan to share any personal data with, except the exchanges where you move hundreds of thousands of dollars.

It would suprise me greatly if Zhou is responsible for this.
I do not have access to any first-hand evidence that would implicate Zhou.
I work on behalf of the fund that invested in Bitcoinica. I have no position of authority with Bitcoinica LP.
When it was made known to me that some suspected Zhou, my recommendation was to confront him privately for his explanation.

In the internal email dump from genjix you are quoted as having written the following:

Quote
Speaking of that, Zhou I wanted your thoughts on the financial situation.
As you know, Bitcoinica went from cranking out 6-figure profit one month to
a flatline the next. I covered most of the deficit from the hack on the
assumption Bitcoinica profits would quickly fill in the rest. What's
happened instead is a consistent equity leak that has remained unresolved
for two months. We've gone from being short 40k to now being short 88k.

https://bitcointalk.org/index.php?topic=93109.msg1039996#msg1039996

Has the reason for that been accurately explained? That is, did Bitcoinica ever - provably - profit to the degree that Zhou claimed it did when you bought it?

One interesting line of thought is that the only one who's ever made a profit from operating Bitcoinica is Zhou, and if the service didn't make a profit from trading the only other explanation is that the "profit" came directly out of user deposits. To cover that up regular "hacks" were simply needed.

I'm sorry but,
  • Who are you?
  • Are you claiming you have evidence that LR account U9236056 is controlled by Zhou Thong? Could you really prove that?
  • What do all those Chinese symbols in your post mean?

Thanks

Let us recall that Zhou himself admitted as recently as earlier this week that he still had access to the LastPass password, and was successfully entering the site.

And as to "illegal" disclosures of personal information by the various businesses involved in this... criminal action is not a defense. If Zhou is involved in this criminal situation, whether as principal scoundrel driving, or incompetent boob reusing the one password that would allow a nefarious friend of his to defeat every security barrier in the world, he cannot use the facts of that criminal act to demand compliance with user privacy policies.

It is nice that you posted this.  I agree, even if ZT was the hacker, this was not the way to go after him.  Thank you for stating your small side to this story.

it's just comming in my mind: is there a possibility to freeze bitcoin addresses also in the future by improving the protocol if the community decided to outlaw a bitcoin address because a hacker used it??

Yay! USD v2.0 here we come!

the current situation tells me a need of this! Wink

Dumbest fucking idea EVER...
