Yahoo knew it had been a target of the same kind of Chinese cyber attacks on US companies before Google raised the alert about such attacks, according to emerging reports.
A source familiar with the situation told Reuters that Yahoo chose to not rock the boat, prior to Google going public about the attacks last week.
Yahoo was 'reckless'
Yahoo's Chinese partner, e-commerce firm Alibaba Group, said that Yahoo's comments that it was aligned with Google's position on the attacks were "reckless."
"Alibaba Group has communicated to Yahoo! that Yahoo's statement that it is 'aligned' with the position Google took last week was reckless given the lack of facts in evidence," the firm said in a statement.
This despite the fact that Alibaba is 40 per cent owned by Yahoo.
Alibaba runs China's largest online retailer, Taobao, and China's largest e-commerce website Alibaba.com
