A few days ago we encountered 2 types of attacks.

1. One out of 40 Genesis wallets was stolen - via a malware we believe now.
2. Botnet attack for increasing to ~ 1 GB/s the Global Difficulty blocking network for 2 hours. This had been done by somebody with a powerful Computation Power. After 60 hours of straight coding, we were able to finally solve all the attacks damages. We did an update on experimental pools and now in the main network too. The update contains two updates 1. Hard fork to "cancel" the effect of ALL transactions sent by the attacker using the Stolen Wallet. 2. Network optimizations for preventing other 50%+1 to change the Network Global Hashrate (difficulty). Right before doing the update, someone which was in our intranet did cut our internet connection and then after we connected directly to the internet our computers was attacked with DDoS.

The blockchain was secured and resisted all the above attacks. Everything works perfectly fine now and the script that "cancel" the effect of the transactions was in place during this fork. I want to add the fact that the transactions are still on the Blockchain because even we can not alter the Blockchain, but the new set of rules "cancel" the effect of those transactions and recover the entire sum.




He used over 300 addresses in order to wash the money
So the attack was very professional, exactly like on Ethereum with the DAO
But in our case, the attacker definitely underestimated our devs so we were able to create an automatic script which tracked all the transactions down in and out automatically directly on the blockchain when the hard fork happened.

By this way we were able to recover all the funds

In order to wash the money, exactly like the Theft happened at Ethereum Classic (before it was called ETH) he used also the addresses of real miners who got over the night a lot of webd. The WebDollar team was able to recover the entire sum from the attacker
