BIOSTAR Ready to Launch Motherboards with Built-in ASICS – Great for Bitcoins

BIOSTAR is now readying a crypto currency (such as Bitcoin) mining motherboard, the BTC-24GH, with 64 ASICs on-board that offers 24GH/s performance which is equivalent to more than 30 ATI 7970 graphic cards. The product is now ready to ship, and BIOSTAR is planning to build up professional operation sites in specific countries. In the Bitcoin world, a "mining rig" is a computer system used for mining bitcoins or other crypto currencies. It can be built specifically for mining or it could be your everyday computer for gaming and surfing, and is used to mine only on a part-time basis.

With the rising price of Bitcoins, GPU mining can theoretically be profitable. What you need is a system that can do enormous amounts of mathematical calculations. Up till now, the best way to do this is the GPUs in graphics cards. Now there are ASICs (Application-Specific Integrated Circuit). ASICs are good at one thing only, solving mathematical hash functions. In this case, their strong hashing power and low power usage, making it very efficient to use.

iBUYPOWER Debuts Coin Mining Systems

Imagine a machine that went to work for you each day and earned you a paycheck, while you relaxed in front of the television. The IBUYPOWER GPU coin mining systems powered by AMD's Radeon HD 290X graphics cards do just that.

Coin mining is taking the world by storm. By crunching data to help support the currency ecosystem, consumers can earn Litecoins, Dogecoins and Lottocoins, among many others. Of course, with all that compute power on tap, you'll be able to crunch through general compute tasks faster than ever.

ASRock Unveils Two Motherboards Made for Bitcoin Mining

Dig the fact that there's probably no way you're ever going to end up dirty rich overnight, not unless you hit the jackpot or discover Davy Jones' treasure. Or maybe what you could try is to mine for the legendary peer-to-peer digital currency bitcoin.

Recently, bitcoin is gaining more and more popularity and value around the globe. A Norwegian man that invested in $27 of bitcoin back in 2009 fluctuated into $886,000 windfall. There's also a new permanent bitcoin ATM installed in Canada. The process of obtaining these digital coins through computing is called "mining", and ASRock is here to assist you to jump in the gold rush immediately with two new motherboards designed for bitcoin mining - H81 Pro BTC and H61 Pro BTC!

Windows 8 Secure Boot Feature: Not So Secure?

We have brought you the potential perils of the upcoming UEFI Forum-implemented - www.uefi.org - Windows 8 secure boot feature here, here and here. However, it appears that it may not be so 'secure' after all, since there appears to be a surefire way to circumvent it, at least for the moment, while it's in development.

Softpedia has scored an exclusive interview with security researcher Peter Kleissner, who has created various Windows (XP, Server 2003 etc) "bootkits", which allow OS infection at the highest privilege level, giving unrestricted access to the whole of the PC. His latest one, called Stoned Lite, shows how the Windows 8 secure boot process, still in development, can be subverted, as it stands. He is planning to release details of how the code works at the upcoming International Malware Conference (MalCon) - http://malcon.org - that will take place in India on November 25th. It appears that the real vulnerability exists in the legacy BIOS boot procedure, not in Microsoft's implementation of secure boot, as Kleissner said:
The problem with the legacy startup is that no one verifies the MBR, which makes it the vulnerable point. With UEFI and secure boot, all the boot applications and drivers have to be signed (otherwise they won’t be loaded). You can compare it to TPM, although Arie van der Hoeven from Microsoft announced that the secure boot feature is mandatory for OEMs who want to be UEFI certified. It is a good message that security is not an option.

Bitcoin & Password Stealer Trojan For Mac Now Available!

Hot on the heels of our previous story of Apple Macs falling prey to a DDoS trojan, we now have another Mac trojan come on the market, as explained by Sophos. Yes, the Apple platform must indeed be becoming more popular to get this one. It's an unfortunate fact of life that the popularity of any computing platform, including smartphones, can be judged by the number of criminals who will attack it. This little nasty, called OSX/Miner-D or 'DevilRobber', hijacks Mac OS X to perform various tricks, which include minting Bitcoins (the virtual and now virtually worthless currency) stealing usernames and passwords (of course) taking screenshots and stealing the victim's Bitcoin wallet while it's at it, if there is one. And for good measure:
it runs a script that copies information to a file called dump.txt regarding truecrypt data, Vidalia (TOR plugin for Firefox), your Safari browsing history, and .bash_history.
So, now the criminals also know about all the sites one has visited, eroding user privacy even more. It looks like this malware has covered all the bases, but wait, there's more.
