Bitalo.com Puts Massive 100BTC Bounty On Hacker

Back in September, we reported on a blackmailer/hacker who had been DDOS attacking the popular bitcoin sports book Nitrogensports.eu and then blackmailing them into paying a ransom for it to stop.

Today, we have been informed by Bitalo.com, a “multi-signature wallet and decentralized exchange” with that they are the latest victim of attacks by the same hacker. The site was offline for two days before coming back online shortly before publishing. Bitalo.com's owners have informed us that rather than give into the hacker's demands, they will be putting up a bounty on the hacker who goes by the pseudonym “DD4BC”. Information leading to his identity will win the bounty, worth 100 BTC.

We have started a new Dry Run to test everything as we prepare to launch the markets and have things go live... https://www.youtube.com/watch?v=Zje91xTd6Lc We are calling everyone into service to prevent Armageddon when we turn on BitAssets.   Your mission is to find and exploit any holes in the market engine before the hard fork lands tomorrow.   If you are successful in your mission to break the market engine there is a $5000 BitUSD bounty for a bug that causes us to delay enabling the markets via price feeds.   Delegates, you should be watching this test.  When you feel this test has been proven to your satisfaction, then publish a price feed for BitUSD on the main network.  Once 50 delegates publish a price feed we will have the dawn of a new era in crypto currencies.
