"Security is moving into the cloud ... so the attacks will follow security into the cloud as well," says Marlinspike. "Password cracking is an obvious thing. Normally, it is cost-prohibitive to run CPU-intensive jobs. [With cloud computing] it costs a lot less money than doing it yourself."
At its core, cloud computing is about providing services or infrastructure through the Internet that can easily be ramped up to meet demand. Online giants, including Amazon, Google, and Microsoft, all have services that offer the ability to run an application in a large data center or to rent time on a cluster of virtual computers, allowing customers to tap into large amounts of computing power more efficiently.
Security experts say the performance and costs advantages of cloud computing are already luring cybercriminals.
