South Korean security officials have removed a "low-risk" worm that was installed on devices linked to the country's nuclear plant control systems. Nothing harmful was discovered on reactor controls, according to officials, despite the recent data breach.

"We will prepare fundamental improvement measures by enhancing nuclear power's safe operation and hiking information security systems to the highest level following this cyber attack case," the Korea Hydro and Nuclear Power company said in a statement.

Korean officials want cooperation from the Chinese government during its investigation of the cyberattacks - with China or North Korea on the short list of foreign states that could be involved. A hacker threatened to close three reactors via Twitter, though only non-critical data was stolen as part of the breach.

The FBI is now investigating the Lizard Squad for its participation in bringing down Microsoft Xbox Live and Sony PlayStation Network via distributed denial of service (DDoS) attacks over Christmas. Published media statements say "Ryanc," a Finnish teenager identified as Julius Kivimaki, as one reported member of the Lizard Squad group - but identifying other members has proven difficult.

"The FBI is investigating the matter," according to a bureau spokesperson when speaking to GamesBeat. "Given the pending nature of the case, we cannot comment further."

Sony Pictures was having a decent year until the crippling cyberattack that made the company's operations go sideways to end the year. To help keep things operating, Sony embraced its old stash of BlackBerry smartphones to support day-to-day operations moving ahead. It's possible, following the breach, some executives will begin embracing BlackBerry smartphones because of the enhanced security protocols.

Despite losing steam among consumers - and in the business workplace - BlackBerry smartphones still rely on a secure infrastructure, making it a popular device for government employees, even with the domination of Apple iPhone and Google Android devices.

"CEO Michael Lynton routinely received copies of his passwords in unsecure emails for his family and his family's mail, banking, travel, and shopping accounts," according to the Associated Press. "Experts say such haphazard practices are common across corporate America." Using a BlackBerry device, however, could help alleviate some of the poor cybersecurity practices suffered by many company executives.

After some Origin users reported fraudulent activity on their accounts, Electronic Arts launched an investigation to try to determine if a data breach occurred. The DerpTrolling hacker group said they compromised up to 1.7 million Origin accounts and passwords, which is why some users could be reporting unauthorized game purchases.

On gaming forums and Twitter, users are reporting Origin receipts in German and Russian appearing in their email inbox - it would seem likely that this isn't a direct breach of Origin's network, and the fraudsters accessed the stolen information posted online by DerpTrolling.

"We found no indication at this point of a breach of our Origin account database," an EA spokesperson told PCGamer. "Privacy and security of user account information are of the utmost importance to use. We encourage our players to use Origin user ID and passwords that are unique to their account, and to report any activity they feel may be unauthorized to EA customer support at help.ea.com."

The FBI believes North Korea played a major role in the breach of Sony Pictures, while the reclusive North Korean government not surprisingly denied any involvement. The Norse cybersecurity firm spoke with the FBI at the start of the week, and believe a piracy group and disgruntled insiders, at least one laid-off Sony Pictures employee, were more likely the cause of the data breach.

"We are very confident that this was not an attack master-minded by North Korea and that insiders were key to the implementation of one of the most devastating attacks in history," said Kurt Stammberger, Norse senior vice president, in a statement to CBS News.

In a statement meant to Reuters, the FBI offered the following statement: "The FBI has concluded the government of North Korea is responsible for the theft and destruction of data on the network of Sony Pictures Entertainment."

ADATA has just announced its new Gold Edition XPG Z1 DDR4 overclocking RAM, which comes in four speeds; 3000/3200/3300/3333MHz. The new memory is perfect for your Haswell-E build, as it will provide some of the best DDR4 RAM for your system, period.

ADATA has decreased the operating voltage of its XPG Z1 RAM from 1.5V to 1.35V, with that 10% reduction in power providing lower temperatures for more stable operation at higher speeds. Even at 3333MHz, the CL16-16-16 timings and a transfer bandwidth of 26.6GB/sec, you can be assured, you're getting some seriously fast RAM with the ADATA kit.

The company has splashed its jet wing-inspired design with a race car carbon texture that ADATA says "embodies the pursuit of extreme performance." The XPG Z1 chips are cooled by its unique Thermal Conductive Technology and 10-layer PCBs with 2oz of pure copper, which has the chips on the XPG Z1 enjoying direct contact with the heat sinks. This means that the IC and PCB "operate at an evenly distributed temperature."

CES 2015: CES is just a week away and we all know what that means, consumer electronics and computer hardware announcements daily. One product we expect to hear about we've already tracked down thanks to someone administering one of Plextor's websites.

This was our initial lead of a new half height, half length (HHHL) PCIe SSD coming from Plextor soon. At first we weren't too sure what it means other than an unannounced 'M6e BK' model coming soon. Like the Nissan Skyline and amazing Mercedes AMG automobiles, Plextor is prepping a Black Edition of the M6e PCIe SSD released in 2014.

After digging further into the deepest trenches of the interwebs, we finally found gold, err black. This should be the first known image of the new Plextor M6e Black Edition.

CES 2015: CES 2015 is just days away, so Lian Li has sent out an e-mail blast telling the world it will be showcasing its new open-air chassis, the O-Series, at the Consumer Electronics Show 2015 in Las Vegas.

If you haven't seen the new Lian Li O-Series open-air chassis, there are a few different models to check out. We have the PC-05, PC-05S, PC-06S and PC-07S, with the company taking feedback in from the DIY community when it began constructing these new designs. All of which feature tempered glass windows, a PCI riser card, and "sleek and alum aluminum construction".

We will be on-hand with these Lian Li cases at CES 2015, so prepare for some coverage from us here at TweakTown next week.

The Interview has only been available through Google Play and YouTube for around a week now, but the movie has quickly become the top selling movie of 2014 for both sites.

During a talk with Bloomberg, a Google spokesperson spilled the beans, but nothing specific on the sales numbers of the Sony flick. Sony has said that the movie has made over $15 million online, but now that it's also on Apple's iTunes service, we should expect those numbers to rise. The James Franco and Seth Rogen comedy is also on Microsoft's Xbox Video, and Sony's own dedicated site - which hasn't been hacked, yet.

CES 2015: CES 2015 kicks off next week, with my bags not even packed yet and I jump on a plane 49.5 hours from now. But, LG is preparing a bunch of stuff to show off to the world, with a huge push in the world of 4K TVs.

The South Korean giant is reportedly going to be showing off no less than eight different product lines (UC9, UB9800, UF9500, UF9400, UF8500, UF7700, UF6800 and UF6700), where we'll see more than just the usual quantum dot technology and webOS 2.0 Smart TV updates we've been hearing about lately. LG's new Ultra HD TV's are thinner than ever before, with the company promising upgrades for the color balance and black levels.

The built-in 4K video decoder can handle both 30FPS and 60FPS inputs, and is "future-proof" for future standards.
