A study proves that software hosted in one part of the cloud can spy on software hosted nearby.

Cloud computing teaches people not to worry about physical equipment for hosting data and running software. But a new study suggests that this could be a costly mistake.

Researchers at University of Wisconsin, University of North Carolina at Chapel Hill, and the computer security company RSA have shown it is possible for software hosted by a cloud-computing provider to steal secrets from software hosted on the same cloud. In their experiment, they ran malicious software on hardware designed to mimic the equipment used by cloud companies such as Amazon. They were able to steal an encryption key used to secure e-mails from the software belonging to another user.
