The Washington Post article Amazon: Hey Spammers, Get Off My Cloud! said

I am accustomed to receiving e-mail from, as I am a fiercely loyal customer who shops there quite frequently. But it took me by surprise this weekend to discover that mounds of porn spam and junk e-mail laced with computer viruses are actively being blasted from digital real estate leased to the e-commerce giant.
I wasn’t the only one who spotted it. Websense Security Labs issued an alert about the spam attacks on Monday, but it didn’t name Amazon as the source. The advisory rightly noted that it had discovered “a substantial number of spam messages utilizing a reliable social engineering trick.” The junk mail claims to have been sent from Microsoft, and urges the recipient to install an attached security update.
But the most interesting aspect of this attack (at least to me) was left out of the Websense advisory: All of the spam came from Amazon’s Elastic Compute Cloud (EC2) servers, which are marketed to companies — mainly small to mid-sized businesses — that want to purchase access to any number of computer applications hosted on the Internet, from data crunching and storage to on-demand computer processing power. These so-called “cloud computing” services potentially put the strength of massive computer arrays in the hands of the average user, and the service is “pay-as-you-go,” so customers only pay for the resources and services they consume.
But to spammers and scammers accustomed to paying for all kinds of Web services with stolen credit cards, Amazon’s service is another place to host their junk, said Suresh Ramasubramanian, head of anti-spam operations at Outblaze, a Hong Kong-based outfit that has listed all of Amazon’s EC2 Internet space on its spam blocklists.
“The [numeric Internet address] for these services can shift within minutes, so if you want to block spam sent from a dynamic address, blocking just one address is not feasible,” Ramasubramanian said. “Right now, if Amazon was able to control or restrict the spam issues, as well as other security incidents on that service, there would be no problems with it.”
