German drugmaker Bayer has contained a cyber attack it believes was hatched in China, the company said, highlighting the risk of data theft and disruption faced by big business.
Bayer found the infectious software on its computer networks early last year, covertly monitored and analyzed it until the end of last month and then cleared the threat from its systems, the company said on Thursday.
"There is no evidence of data theft," Bayer said in a statement, though a spokesman added that the overall damage was still being assessed and that German state prosecutors had launched an investigation.
