Over the past decade, hackers have stolen trade secrets, millions of personal identities, and wrought havoc on some of the world's biggest companies. Some of these actions were orchestrated by lone criminals; some by governments. All of them share one thing in common: The details are never revealed. That changed in 2014 when Bloomberg Businessweek published a trio of deeply reported stories by Michael Riley and Bloomberg colleagues about digital attacks. Each vividly takes readers into the secretive world of hackers and exposes corporate America's vulnerabilities in startling detail. “The Epic Hack: Target ignored its own alarms - and turned its customers into victims," "How Russian Hackers Stole the NASDAQ” and “Now at the Sands: Iranian Hackers in Every Server” exemplify superlative investigative reporting in a complex field alongside masterful storytelling.
