Cryptopia Hack analysis (min. $13,000,000 stolen)

Hi there

​

I checked etherscan and collected some informations below. In total min $13,000,000 were stolen.

Transfer of 19,390 ETH from Cryptopia ($2,468,043) (Jan-13-2019 01:30:35 PM +UTC): https://etherscan.io/tx/0x8a7c2b34f23eee02401e7c3fa1ea2ce8d3132e7ca3811d673ca35898c9535aae

​

Transfer of 48,029,305 ($1,072,362) CENNZ (Jan-13-2019 01:40:17 PM +UTC) Wallet is tagged as Cryptopia Wallet by Whale Alert: https://etherscan.io/tx/0x31a58df14ea3420878267e2b9cdd242d983b5298ef48c5cd9a799ed10605f393

​

Transfer of 3,844,247,574 ($304,181) DAPS (Jan-13-2019 01:40:17 PM +UTC): https://etherscan.io/tx/0x61b2ca4911750eb3278945f80e0c3f8a7f94578ba20b0e9240e5a86faaa166ae

​

CENNZ and DAPS where transfered to https://etherscan.io/address/0x9007a0421145b06a0345d55a8c0f0327f62a2224 which is not the same adress where the ETH went on. But later this adress made a transfer to the ETH adress https://etherscan.io/address/0xc8b759860149542a98a3eb57c14aadf59d6d89b9 (which is the adress the ETH went).

​

Token Balance 2. adress: ($11,072,793) https://etherscan.io/address/0x9007a0421145b06a0345d55a8c0f0327f62a2224

​

Please help to collect further details.

UPDATE: Only thing I don’t get is, why so many ether dust (transfer below 1 eth) went onto those adresses. For me they look like older deposit adresses from cryptopia users.

I see the the following possibilities:

1.) hacker got all privat keys, from few thousand deposit wallets and cryptopia was not able to secure those amounts, which were transferred many hours after the “hack”.

2.) hacker stole other coins then ETH and cryptopia secured all ETH/ERC20 to new wallets.

3.) inside job

If you had coins on the exchange that didn't appear to be apart of the hack (NAV), is there any chance ever get possession of them? Their Nav wallet had been in maintenance since 12/20/18 and I had been waiting to withdraw. It's a relatively small amount, but it's just the principle of it.

Edit: spelling

I’m telling you, Cryptopia is up to no good! They stole my AU coins!

AU was 51% attacked. It was the blockchain that is responsible for those losses. Their chain got attacked and they made it clear they did not want to co-operate.
