China's full-throated denials of hacking and counter-accusations of its own do nothing to allay growing concern over large-scale cyberspying alleged in a bombshell report this week, Western analysts said.

Chinese officials and state-run media have lashed out after a report by a U.S. firm laid out in unprecedented detail what Western officials and experts have long claimed: that China's army runs an aggressive hacking operation targeting U.S. firms.

Facebook co-founder Eduardo Saverin said Thursday the success of the social networking site would be hard to match but he hoped to make an impact as an Asia-based technology investor.

"It's clearly a tough act to follow," the 30-year-old Brazilian billionaire told a business conference in Singapore, where he is a permanent resident and putting money as an "angel investor" into Asian and other start-ups.

Sony unveiled a new generation PlayStation 4 system Wednesday and laid out its vision for the "future of gaming" in a world rich with mobile gadgets and play streamed from the Internet cloud.

At a press event in New York, computer entertainment unit chief Andrew House said PS4 "represents a significant shift from thinking of PlayStation as a box or console to thinking of the PlayStation 4 as a leading place for play."

Chinese state media stepped up the war of words Thursday over allegations of sophisticated cyberattacks on U.S. firms, branding the accusations a "commercial stunt" and accusing Washington of ulterior motives.

American Internet security firm Mandiant earlier this week said that a Chinese military cyberspy unit is targeting U.S. and other foreign firms and organisations with hacking attacks.

Hackers referencing hip-hop acts took over U.S. automaker Jeep's Twitter account Tuesday in an attack not unlike one the day before that targeted fast food chain Burger King.

"The official Twitter handle for the Jeep® -- Just Empty Every Pocket," read the revised profile at @Jeep that claimed the Chrysler division had been sold to General Motors' luxury brand Cadillac.

Apple on Tuesday said it suffered a cyber attack similar to the one recently carried out against Facebook, but that it repelled the invaders before its data was plundered.

The maker of iPhones, iPads, iPods, and Macintosh computers said it is working with law enforcement officials to hunt down the hackers, who appeared tied to a series of recent cyber attacks on U.S. technology firms.

Sony is expected to reveal its vision of the future of home entertainment on Wednesday by providing a glimpse at a new-generation PlayStation console that streams games, films, music and more.

"Sony needs a big hit with this game console," said Forrester analyst James McQuivey.

French videogame maker Ubisoft on Tuesday began selling computer games made by Electronic Arts, Warner Brothers and other rivals at its online Uplay shop.

California-based Electronic Arts, in turn, added Ubisoft hits including "Assassin's Creed III" and "Far Cry 3" to its Origin network for play as the companies ramped up their challenge to Valve Corporation's Steam service.

Microsoft is so confident it has the Internet's best email service that it's about spend at least $30 million to send its message across the U.S.

The barrage begins Tuesday when Microsoft's twist on email, Outlook.com, escalates an assault on rival services from Google Inc., Yahoo Inc., AOL Inc. and a long list of Internet service providers.
