ThyssenKrupp secrets stolen in 'massive' cyber attack this year

Technical trade secrets were stolen from ThyssenKrupp AG in a cyber attack earlier this year, the steelmaker said on Thursday.

"ThyssenKrupp has become the target of a massive cyber attack," the German company said in a statement.

In attacks discovered in April and traced back to February, hackers stole project data from ThyssenKrupp's plant engineering division and from other areas yet to be determined, the company said.
