What Hacker News says?
My guess at how the attackers are doing it: They are calling splitDAO: https://github.com/slockit/DAO/blob/develop/DAO.sol#L618 splitDAO calls withdrawRewardFor which ends up calling back into the users contract. https://github.com/slockit/DAO/blob/develop/DAO.sol#L686 withdrawRewardFor(msg.sender); // be nice, and get his rewards totalSupply -= balances[msg.sender]; balances[msg.sender] = 0; paidOut[msg.sender] = 0…

HN discussion- I don't think there's any definitive details yet, but it could be an instance of this attack [1]. The code behind the DAO is available here [2]. Apparently [3], there's a bug where one can recursively call `splitDAO` multiple times to extract ether from the contract if one has a split open. - Ether can go missing when it is sent to a public address which has no known corresponding private key. It's a "we can't inv…

HN discussionIt's a reentry bug - native ETH always calls the recipient contract's code on transfer, which can call back into the current function. If you manage native ETH do accounting in the wrong order, you can "withdraw" multiple times. It doesn't "go missing", presumably the hacker will drain it into Bitcoin via any anonymous exchange accounts they have. Everyone loses big time (except the attacker if they manage to launde…

I can't reveal much more information on it until the project formally goes live (which is imminent), but I can't tell you it thankfully goes a lot further than what you noted.

HN discussionSo it turns out that the DAO is buggy. Hardly a surprise, given that it has hundreds of lines of code. What is surprising though is that the code was allegedly audited for bugs and security problems before release: https://blog.slock.it/deja-vu-dao-smart-contracts-audit-resu... ... and they found none of these big problems. What does that say about code audits?
