Today's Tech: Nokia unleashes Lumia 625 4G smartphone and Canonical crowdsources Android/Ubuntu dual-OS 'converged' Ubuntu Edge

Nokia has unveiled the latest addition to its Lumia smartphone range in London, touting the Lumia 625 as "one of the most affordable 4G devices" in the UK. In addition to 4G connectivity, the Lumia 625 will feature a 4.7in LCD display with a resolution of 800 x 480 pixels, as well as packing a 1.2GHz dual-core Snapdragon S4 processor, 512MB of RAM, 8GB of on-board storage and a 2,000mAh battery. Elsewhere, the Lumia 625 sports a 5-megapixel primary camera as well as a VGA (480p) front-facing shooter. The device features key measurements of 133.25 x 72.25 x 9.15mm and weighs 159g. There's also room for a microSD card slot and the Lumia 625 will, of course, run Microsoft's Windows Phone 8 mobile OS. Nokia indicated this morning that the product will come to market in "early-September" and will retail for £200.

Despite its vocal advocacy of fair play in the cyber-sphere, the United States remains the number one source of cyber-attacks according to data security specialist Imperva. The company's annual Web Application Attack Report found that the United States was the primary source of most attack vectors in this Internet battleground, topping the charts for SQL injections, comment spam, directory traversals, and the exploitation of file inclusion vulnerabilities. In a study spanning over six months, Imperva scrutinised Internet traffic heading to 70 different web applications to identify key trends in the current threat landscape. The report does not make good reading for the US, though Imperva was keen to point out the difficulty in country-attribution for cyber-attacks, and the tendency for data to be skewed depending on natural Internet activity. "We have to remember that most of the Internet traffic comes from the US and there are a lot of servers and clients there. The Internet is still very much US-centric," Imperva's Web Security Research Team Leader, Tal Be'ery told ITProPortal. For more details of the study, follow the link above.

The Syrian Electronic Army (SEA) claims to have successfully hacked free video and text messaging service Tango. The organisation, which is loyal to Syrian President Bashar-al-Assad, boasted that it breached Tango's website and back-up, database, managing to steal sensitive personal data, including private phone numbers, contacts and email addresses. The stolen information allegedly amounts to 1.5TB of data. The SEA said it will forward the information to the Syrian government. Tango took to Twitter to confirm the data hack, writing, "Tango experienced a cyber intrusion that resulted in unauthorized access to some data. We are working on increasing our security systems." To add proof to its claims, the SEA posted screenshots of the hack to its website, prompting Internet security experts to speculate that Tango's use of an old version of the WordPress content management system was the reason for the breach.

The London-based developer of open source operating system Ubuntu is looking to crowdsource a record-breaking $32 million (£20.83 million) to produce a dual-OS smartphone that runs Ubuntu Touch OS and Android. Canonical hopes to raise the funds in just a month through Indiegogo, with donations being taken until 21 August. At the time of writing, $3.38 million (£2.2 million) has been raised. The Ubuntu mobile OS will work differently to any other smartphone OS, as when the phone is plugged into a monitor, the display will change from a smartphone display to Ubunto Desktop PC, transforming the phone into a kind of computer system unit. It will pack a 4.5in sapphire crystal screen, which is resistant to all materials except diamond, claims Canonical. Its resolution will be 1,280 x 720, but Canonical says it is focusing on "colour accuracy and brightness" rather than sharpness. The Ubuntu Edge will also carry 128GB of internal storage, at least 4GB of RAM, an 8-megapixel rear camera and a 2-megapixel front-facing one. It will also feature a yet-to-be-unannounced processor, which Canonical assures us will be the "latest, fastest processor" available at launch, which is scheduled for May 2014.
