Please read this blockbuster Bloomberg Businessweek report about U.S. investigations into a digital attack that involved planting snooping devices in the kinds of circuit boards used by Amazon, Apple, the U.S. government and other important organizations. The reporting highlights the grave risk of a bedrock element of technology: the sprawling, interconnected and global nature of computing.
