“Silicon Valley has a long history of thievery and espionage. A year before the Adara break-in, a burglar cracked open the door at networking-software company Nicira, an Adara rival, in a matter of seconds. That thief went straight to a top engineer’s desk and stole a computer carrying the source code for some of the most promising software in Silicon Valley. (Nicira was later acquired by software maker VMware (VMW) for $1.2 billion.) Given the target company and the skill of the crime, federal investigators suspected that Russia or China was behind the attack.”
