Yeah, we heard that the DAO has been attacked. I am so curious about how long it took for the attacker to perform the whole transactions?
The first attack took place in transaction 0x0ec3f2488a93839524add10ea229e773f6bc891b4eb4794c3337d4495263790b that occurred in block 1718497 mined 9 hrs 15 mins ago (6/17/2016 3:34:48 AM).
The attack seems to have stopped with the last transaction 0xa348da60799bff3ca804b3e49c96edebea44c5728a97f64bec3e21056d42f6e3 that occurred in block 1720245 mined 1 hr 51 mins ago (6/17/2016 11:00:23 AM).
Here is the contract address 0x304a554a310C7e546dfe434669C62820b7D83490 that was receiving the hacked ethers.
And here is the list of the 27996 internal transactions to transfer the ethers.
The whole attack took 7 hours 24 minutes.
Some Other Statistics
- 3,641,694.241898506 Ether ($59,578,117.80) was moved to the account 0x304a554a310c7e546dfe434669c62820b7d83490.
- 7,928,991.62 Ether ($130,590,492.12) is remaining in The DAO, with an additional 344,907.73 Ether ($5,680,630.44) in the extraBalances account.
- 30.56% of ETH from The DAO was hacked. Calculation: 3,641,694.241898506 / (3,641,694.241898506 + 7,928,991.62 + 344,907.73).
- The current total token supply is 1,155,955,830.9 The DAO ($138,714,699.71).
If the hardfork described in CRITICAL UPDATE Re: DAO Vulnerability is accepted by consensus, The DAO is dissolved, and the ETH returned to The DAO token holders, each 100 DAO tokens would receive 1.03 ETH (without taking into account the token holders who paid > 1 ETH = 100 DAO). Calculation: (3,641,694.241898506 + 7,928,991.62 + 344,907.73) / 1,155,955,830.9 = 0.010308001 .
But according to Thoughts on The DAO Hack, funds in the extraBalances is not accessible, so the number is more 1.00096263 ETH = 100 DAO. Calculation: (3,641,694.241898506 + 7,928,991.62) / 1,155,955,830.9 = 0.0100096263 .
And if the hardfork described in CRITICAL UPDATE Re: DAO Vulnerability is rejected by consensus, The DAO token have 0.7157625861 ETH backing each 100 DAO tokens. Calculation: (7,928,991.62 + 344,907.73) / 1,155,955,830.9 = 0.7157625861 .
And if funds in the extraBalances is not accessible, DAO tokens have 0.68592514 ETH backing each 100 DAO tokens. Calculation: 7,928,991.62 / 1,155,955,830.9 = 0.0068592514 .
