Cloud Computing providers offer gigabytes of storage for free, and the cybercriminals use to maintain and spread malware of all the kind. At the same time, many legitimate services are not free, but are still very attractive to cybercrime gangs. In the case of Amazon, Amazon Simple Storage Service (Amazon S3) does the trick.

Despite being a paid service, the cost is not an obstacle for profitable attackers. In fact, my colleague Dmitry Bestuzhev recently told us about the spread of malware exploiting this service to "the cloud".

The truth is that these cases are not isolated. According to our research, cybercriminals have been running SpyEye activities and from Amazon for the past couple of weeks.

    There were some recent comments about Amazon Cloud as a platform for successful attacks on Sony… Well, today I found that Amazon Web services (Cloud) now is being used to spread financial data stealers.
