Hackers hit Norsk Hydro with ransomware
> The breach last March would ultimately affect all 35,000 Norsk Hydro employees across 40 countries, locking the files on thousands of servers and PCs. The financial impact would eventually approach $71 million.
> All of that damage had been set in motion three months earlier when one employee unknowingly opened an infected email from a trusted customer. That allowed hackers to invade the IT infrastructure and covertly plant their virus.
This is kinda fluffy, but somewhat interesting.
