Today's Tech: New 64-bit Apple iPad to crack enterprise and send PC prices tumbling and Samsung launches curved Galaxy Round

The man thought to be behind the infamous Blackhole malware toolkit has been arrested in Russia, an inside source has revealed. The source - a former police detective with contacts in the Russian government - said that the man arrested was the notorious hacker who goes by the online handle 'Paunch'. Blackhole is an exploit kit that allows hackers to carry out so-called 'drive-by' attacks on computers, a style of infiltration that accounts for more than half of all attacks taking place on users. These drive-by hacks can include the downloading of anything from viruses to botnet Trojans and keyloggers onto infected machines. The rootkit was once considered the largest malware threat in the world, and until recently, 91 per cent of web threats detected by AVG were thought to be due to the toolkit.

The new Apple iPad is expected to scupper the struggling PC market, with analysts predicting the 64-bit model will give Apple added penetration into the corporate space. Deutsche Bank has cut estimates for growth in PC shipments for both 2013 and 2014 with it now predicting minus 10 per cent and minus eight per cent growth for the respective years, down from minus eight per cent and minus six per cent that was projected originally. The 64-bit architecture being referred to is Apple's new A7 chip that is expected to be under the hood of the new Apple iPad 5 and was the main attraction of the recently released iPhone 5S. The same analyst expects PC sellers to fight this by taking down the price of Windows 8 ultrabooks to compete with the price at which tablets are being positioned.

Panasonic is planning to bow out of the Plasma TV market by March of 2014, sources reporting to Reuters and Nikkei claim. Despite being rumoured for some time, the exit comes sooner than expected as the Japanese electronics giant focuses its attentions on the more profitable manufacturing of LDC and OLED TVs instead. Not so long ago Panasonic's TV division was the company's biggest success story, raking in more than £6.9 billion in 2010. Recently, however, it has devolved into a drain on the company's financials. The electronic company reported a combined £9 billion net loss over the last two years, with the TV division operating on a loss of £571.5 million in the last financial year alone.

Samsung is seeking to make a dent in the competitive market for high-end smartphones with the introduction of the Galaxy Round, a phablet with a curved display. The concave phone sports a 5.7in AMOLED screen – the same measurement as the recently released Galaxy Note 3 – but here the Galaxy Round throws a significant curve ball by gently bending along a vertical axis. Samsung claims that this curvature comfortably fits the contours of a person's face with no flex or bend - and at 7.99mm thick weighing just 154g, it should fit snugly in the palm of your hand too.
