Hackers Stole Over $20 Million From Misconfigured Ethereum Clients (bleepingcomputer.com)

Catalin Cimpanu, writing for BleepingComputer: A group of hackers has stolen over $20 million worth of Ethereum from Ethereum-based apps and mining rigs, Chinese cyber-security firm Qihoo 360 Netlab reported today. The cause of these thefts is Ethereum software applications that have been configured to expose an RPC [Remote Procedure Call] interface on port 8545. The purpose of this interface is to provide access to a programmatic API that an approved third-party service or app can query and interact or retrieve data from the original Ethereum-based service -- such as a mineror wallet application that users or companies have set up for mining or managing funds. Because of its role, this RPC interface grants access to some pretty sensitive functions, allowing a third-party app the ability to retrieve private keys, move funds, or retrieve the owner's personal details.

Rpc for native clients has only been only been enabled for localhost. Someone or something has to configure it for remote access. It takes some work to make it happen
