WikiLeaks supporters' group abandons cyber attacks

LONDON — A loose grouping of cyber activists supporting WikiLeaks has abandoned its strategy of online attacks on organizations seen as hostile to the site in favor of spreading the leaked documents far and wide online.

Internet activists operating under the name "Anonymous" temporarily brought down this week the websites of credit card giants MasterCard and Visa — both of which had stopped processing donations to WikiLeaks.

The United States, enraged and embarrassed by WikiLeaks' publication of thousands of confidential U.S. diplomatic cables, has leant on organizations from Amazon to online payments service PayPal — which have now withdrawn services to WikiLeaks.

In an overnight blog post, Anonymous announced a change of strategy, saying it now aimed to publish parts of the confidential U.S. diplomatic cables as widely as possible and in ways that made them as hard as possible to trace.

The cyber activists briefly brought down PayPal's official blog by bombarding it with requests this week but failed to harm retail and Web-hosting giant Amazon, which withdrew its services to WikiLeaks more than a week ago.

"We have, at best, given them a black eye. The game has changed. When the game changes, so too must our strategies," said the blog post announcing "Operation: Leakspin."

The activists are now encouraging supporters to search through leaked cables on the WikiLeaks site and publish summaries of ones that have been least exposed, labeling them so they are hard to find by any authority seeking to quash them.

"Use misleading tags, everything from "Tea Party" to "Bieber." Post snippets of the leaks everywhere," the blog said, referring to the U.S. grassroots conservative movement and the 16-year-old Canadian pop phenomenon Justin Bieber.

Similar strategies have been used in the past on YouTube and the now-defunct Napster by users seeking to share video and music while dodging copyright crackdowns.

The activists had previously been using denial-of-service attacks, in which they bombarded the Web servers of the perceived enemies of WikiLeaks with requests that crashed the sites, in an operation named "Operation Payback."

DRAM prices to keep falling through the first half of 2011

The price of DRAM, the main memory inside personal computers, will likely keep falling throughout the first half of next year before a recovery takes hold, analysts and market researchers say.

The chips, which are important to the overall speed of a computer, have been pricey over the past year because of a PC industry recovery. But in recent months, shaky consumer confidence has hurt PC sales and sent chip prices down. Increased production by DRAM makers has further hurt chip prices, and more factory capacity is coming on line that will keep DRAM prices on the decline.

The price of high-end 2GB DDR3 (double data rate, third generation) DRAM modules declined to US$25 in the first half of November, down 46 percent from its peak of US$46.50 in the first half of this year, according to DRAMeXchange. The market researcher forecast the price will fall to US$20 by the end of this year.

Increased output by Samsung Electronics has recently pushed the price lower, while production increases by its rivals has kept up price pressure in the fourth quarter, DRAMeXchange said.

Samsung expanded capital spending aggressively early this year, with 9 trillion Korean won (US$7.8 billion) earmarked for its memory chip business, a massive sum for one company. During its third quarter investors' conference, Samsung executives said they expected DRAM prices to fall as much as 30 percent by the end of this year.

iSuppli analyst Mike Howard, believes Samsung aims to capture as much as 50 percent market share in DRAM and has worked hard to expand and upgrade its factories.

"By investing heavily in expanding production and advancing its manufacturing technology, the company has been able to cut pricing and to eat into the market share of its competitors," he said in a statement.

Samsung's share of the global DRAM market surged to 40.7 percent in the third quarter, up from 35.4 percent in the second quarter.

Falling DRAM prices normally mean PC buyers will find bargains when shopping for new computers. This time, while prices may fall for DRAM modules sold in stores, PC vendors appear to be planning to offer better overall systems instead of lowering prices.

At a recent investors' conference, Gianfranco Lanci, president and CEO of Acer, said prices of a number of components had fallen, including DRAM and LCD panels, but, "you're probably not going to see the price [of a PC] going down, you're likely to see the specs going up."

Acer is one of the world's biggest PC vendors.

Investment banking firm Credit Suisse forecast the DRAM market will remain in oversupply through the middle of 2011 but will regain footing in the second half of the year. The firm said quarterly DRAM revenue will likely bottom in the first quarter of next year before starting to recover in the second quarter.

Microsoft Says Malware Causing Blue Screen Crashes

A hard-to-detect rootkit may be causing Windows XP systems to crash following Microsoft's latest security updates.

Windows users began flooding Windows support forums this week, saying that their computers had been rendered unusable with a blue-screen-of-death (BSOD) error after installing Microsoft's February security updates, released Tuesday. On Thursday, Microsoft stopped shipping the MS10-015 update, which had been linked to the issue, and said it was investigating.

On Friday, Microsoft offered a preliminary conclusion, saying that malicious software may be to blame. "Malware on the system can cause the behavior," wrote Microsoft spokesman Jerry Bryant on a company blog. "We are not yet ruling out other potential causes at this time and are still investigating."

"We have confirmed cases where removing malware allows the system to boot," Bryant said in a Twitter message.

Windows XP user Patrick Barnes said he'd traced the issue to a malicious rootkit program known as TDSS that he found on one of his systems.

In a post to the Internet Storm Center, Barnes said that he'd identified a nonworking file on his system called atapi.sys. When he submitted the file for analysis it turned out to be the TDSS rootkit.

It may not be the only cause of the problem, however.

"From the reports I have been receiving, the infected atapi.sys is the most common cause of this blue screen," Barnes wrote in his post. "However, any driver that references the updated kernel bits incorrectly can also cause this blue screen."

Barnes posted standalone utility that removes the TDSS infection, however.

Users must first remove the rootkit from their hard drive before they can repair the issue or apply the security update, Barnes wrote in the Internet Storm Center post. People who have experienced the BSOD should remove their hard drive and then scan it for infections using another PC to make sure they catch it. "If atapi.sys is removed, you will need to replace it from installation media or from another Windows system of the same version," Barnes wrote. "Restore your hard drive and attempt to boot again. If it still does not boot, you may try a repair installation of Windows. If that still does not work, you may need to reload your computer."

Because TDSS uses crafty techniques to hide itself on the operating system, many antivirus programs have a hard time detecting it, said Roel Schouwenberg, a Kaspersky antivirus researcher. "The more I look into it, the more plausible it becomes that this is indeed the (main) issue behind the BSOD. MS10-015 is a kernel update with atapi.sys containing the extremely advanced TDSS kernel rootkit," he said via instant message. "Microsoft pulling the patch obviously says something about how widespread this thing is."

Barnes' repair instructions "make sense," Schouwenberg said. "Given the nature of the BSOD I doubt there's an easier way."

Microsoft has said that the issue affects a "limited number" of customers

Google becoming "giant monopoly"

BERLIN (Reuters) – Internet search engine Google Inc is becoming a "giant monopoly" like Microsoft and could face legal action if it does not become more transparent, Germany's justice minister said.

In an interview with weekly magazine Der Spiegel Sabine Leutheusser-Schnarrenberger said she was concerned the firm was accruing too much power and information about citizens via programs like Google Earth and Google Books.

"All in all, what's taking shape there to a large extent is a giant monopoly, similar to Microsoft," the minister said.

"My initial response is not to ban something or stop something. But I do want to create more transparency and ensure that users know what is going on with their data," she added.

"I think the companies have an obligation here, and a lot of things ought to be improved. If that doesn't happen soon we may have to take action as legislators."

A liberal member of the business-friendly Free Democrats (FDP), Leutheusser-Schnarrenberger also served as justice minister between 1992 and 1996, when she stood down in protest about moves to allow the state more scope to snoop on citizens.

A spokesman for Google in Germany said offering users full transparency was central to how the company operated and that it was constantly working to make improvements in this realm.
