London: Days after the Wall Street Journal said Chinese hackers were targeting its computers, News Corporation owner and media baron Rupert Murdoch on Wednesday said attacks continued over the weekend.
"Chinese still hacking us, or were over weekend", Murdoch tweeted.
However, his tweet led to a series of critical responses referring back to phone hacking by News of the World, owned by Murdoch's News Corporation, which also runs the Wall Street Journal.
One of the users Jonathan Paige commented "you're something of an expert on that topic, aren't you?"
Another user @CalebRapoport tweeted "@rupertmurdoch what do you know about hacking," prompting a response from Murdoch.
In his reply, the media mogul tweeted, "@CalebRapoport what do I know about hacking? Nothing until about two years ago. One newspaper guilty several years ago. Nothing since."
Earlier on February 1, the Journal - one of America's leading papers - had come out saying the hackers were attacking the newspaper's computers to spy on journalists covering China.
Before the latest revelation by the organisation, the New York Times had also accused Chinese hackers of carrying out sustained attacks on its computer systems, breaking in and stealing the passwords of reporters after the paper's expose of vast wealth amassed by Chinese Premier Wen Jiabao's family.
