Internet giant Google said that the firm had disrupted attempts to hijack Gmail accounts originating from China.
Google began a blog post entitled "ensuring your information is safe online" by warning of the threats of malware and phising shames. Such attacks were deployed indiscriminantly in order to steal identities for the purposes of fraud and spam, Google said.
However Google went on to add that some attacks were targetted at specific individuals and announced that the firm had disrupted a "campaign to collect user passwords" originated from Jinan, China.
Among those targetted were sensior US government officials, Chinese political activists, military personnel and journalists. Google made a similar accusation last year and retaliated by announcing the firm would no longer censor search results in China. Google ultimately was forced to largely withdraw from the market.
"The goal of this effort seems to have been to monitor the contents of these users’ emails, with the perpetrators apparently using stolen passwords to change peoples’ forwarding and delegation settings," Google said
Google formerly acused the Chinese government of interefering with the firm’s popular Gmail service following widespread reports of slow-downs. The Chinese government denied the claims.
Detailing ways to improve security, Google highlighted the firm’s recently introduced two-step verification.
"Please spend ten minutes today taking steps to improve your online security so that you can experience all that the Internet offers while also protecting your data," Google said.
