Hackers take down websites of 3 Greek banks; demand ransom in bitcoins

http://www.ibnlive.com/news/tech/hackers-take-down-websites-of-3-greek-banks-demand-ransom-in-bitcoins-1170884.html

Hackers have staged cyber-attacks on three Greek banks and demanded a ransom in bitcoins, a virtual monetary unit, to stop their disruption, banking sources said on Monday.

The sources said the hackers managed to block the Internet banking activity of three Greek lenders for a few hours last Thursday but did not penetrate the banks' security or obtain confidential client data or access to accounts.

There are several different types of Bitcoin clients. The most secure are full nodes like Bitcoin Core, which will follow the rules of the network no matter what miners do. Even if every miner decided to create 1000 bitcoins per block, full nodes would stick to the rules and reject those blocks.
