In a follow piece for Wired, Mat Honan, whose online life was basically wiped out when hackers socially engineered their way into his Amazon and iCloud accounts, describes the process of piecing things back together:
When my data died, it was the cloud that killed it. The triggers hackers used to break into my accounts and delete my files were all cloud-based services — iCloud, Google, and Amazon. Some pundits have latched onto this detail to indict our era of cloud computing. Yet just as the cloud enabled my disaster, so too was it my salvation.
If you haven’t read the original piece yet, go ahead and do so. It should be required reading for anyone with cloud-based accounts such as Dropbox, iCloud, and Gmail/Google Apps.
