Highlighters at the ready, folks: Apple has revealed details about the 2013 iteration of its Worldwide Developers Conference, which will take place in San Francisco between 10-14 June. Tickets to the annual showcase, to be held at the Moscone West exhibition centre, will go on sale to tomorrow at 18:00 BST and are widely expected to sell out almost instantly. While WWDC is pitched primarily at Apple's developer community, it is also often used as a platform for the company to launch new technology, especially on the software front. In fact, it wouldn't come as a surprise at all if Apple launched iOS 7 at WWDC 2013. Follow the link for more details about the annual Apple hobnob.

But the newly-released statement provides some juicy reading and throws more suspicion over the cyber conduct of China, so read on for all the fresh claims.

Indeed, reports of China's involvement in global cyber espionage are as common as snowflakes in winter. A second new study, Verizon's annual Data Breach Investigations Report, confirms that China was indeed behind plenty of cyber attacks in 2012, with hackers targeting data that furthers national interests, such as military or classified information, economy-boosting plans, insider information or trade secrets, and technical resources such as source code. According to this particular report, "state-affiliated actors tied to China [were] the biggest mover in 2012. " Follow the link for more details about the digital trickery that went on last year.
