• Activision requires real names for use of forums

NEW YORK — Activision Blizzard Inc.’s move to require people to use their real names if they want to post messages in online forums for games is the latest sign that online anonymity is falling out of favor with many companies.

The upcoming change has upset many gamers who prize anonymity and don’t necessarily want their gamer personas associated with their real identities.

Blizzard, the maker of "World of Warcraft," said Tuesday that the new rule will go into effect later this month. It will apply first to forums about the highly anticipated "StarCraft II," out July 27; other games are to follow.

Blizzard hopes that making people use their real names will cut down on nasty behavior in the forums and create a more positive environment. Players will have the option – but not a requirement – to display the name of their main game character alongside their real name.

Marc Rotenberg, executive director of the Electronic Privacy Information Center, said Blizzard is the latest company to require real identities. But he added businesses have "a lot of freedom" in doing so.

Facebook, the world’s most popular online social network, asks users to sign up with their real names. The company tries to delete fake profiles it comes across. A growing number of blogs and news sites are also abandoning anonymity. The Buffalo News said last month it will start requiring commenters on its website to give their real names and the towns they live in, just as they would do in a printed letter to the editor.

Online games are among the last truly anonymous frontiers. As such, Rotenberg called Blizzard’s decision a "bit of a sad day" in the world of gaming.

"Part of the fun of the online gaming would was the sense that you could construct a character different form who you were in the real world," he said.

"World of Warcraft" has more than 11.5 million subscribers who pay monthly fees to play the game worldwide.

• Malware triggers more cyber attacks

SEOUL, South Korea — Hundreds of computers that caused a wave of outages on U.S. and South Korean government websites last July launched new attacks on the same sites, but no major damage was reported, police said Thursday.

More than 460 computers infected with malicious computer codes assaulted 25 websites, including that of South Korea’s presidential Blue House, on Wednesday as they are programmed to attack every July 7, said Jeong Seok-hwa, a police officer handling investigations on the cyberattacks.

"But the attacks were so weak that there were no problems in accessing the sites," he said.

An analysis of an infected computer in Seoul showed that it was programmed to attack every July 7 and the malicious computer codes used were identical to those mobilized last year, said Hyun Jae-sub, another police official.

Hyun said the attacks are traced to computers which were not vaccinated after the last year’s attacks. He said about 270,000 infected computers were involved in last year’s assaults.

The malicious computer codes, called malware, are used in triggering so-called denial of service attacks, in which large numbers of computers try to connect to a site at the same time to overwhelm the server.

Vaccine programs can repair the infected computers and prevent denial of service attacks, according to AhnLab, a top South Korean cybersecurity company.

• Sony cuts price of its e-reader

SAN FRANCISCO — Sony has cut the prices on its electronic-book readers to keep up with competition from Amazon.com and Barnes & Noble, which both recently slashed prices on their own e-readers.

Sony Corp. spokeswoman Valerie Motis said Wednesday that Sony last week dropped the price of its Reader Daily Edition by $50, to $300. Like Amazon.com Inc.’s Kindle and Barnes & Noble Inc.’s Nook, the Daily Edition can download e-books wirelessly.

Sony lowered the price of its Reader Touch Edition by $30, to $170, and the Reader Pocket Edition by $20, to $150.

Last month, Amazon cut the Kindle price by $70, to $189, just hours after Barnes & Noble reduced the Nook price by $60, to $199. Both face competition from Apple Inc.’s iPad, which starts at $499.
