Amazon.com Inc. (AMZN)â€™s Web Services cloud- computing unit was used by hackers in last monthâ€™s attack against Sony Corp. (6758)â€™s online entertainment systems, according to a person with knowledge of the matter.
Hackers using an alias signed up to rent a server through Amazonâ€™s EC2 service and launched the attack from there, said the person, who requested anonymity because the information is confidential. The account has been shut down, the person said.
The development sheds light on how hackers used the so- called cloud to carry out the second-biggest online theft of personal information to date. The incursion, which compromised the personal accounts of more than 100 million Sony customers, was â€œa very carefully planned, very professional, highly sophisticated criminal cyber attack,â€ Sony has said.
