Apple iPhone fingerprint sensor hacked by Germany's Chaos Computer Club
Germany's Chaos Computer Club says it has cracked the fingerprint scanner on the new iPhone 5S.
Biometrics are not safe, says famous hacker team who provide video showing how they could use a fake fingerprint to bypass phone's security lockscreen
In a post on their site, the group says that their biometric hacking team took a fingerprint of the user, photographed from a glass surface, and then created a "fake fingerprint" which could be put onto a thin film and used with a real finger to unlock the phone.
The claim, which is backed up with a video, will create concerns for businesses which see users intending to use the phone to access corporate accounts. While it requires physical access to the phone, and a clean print of one finger which is one of those used to unlock the phone, it raises the risk of a security breach.
Blackberry to cut 4,500 jobs
Blackberry has announced it is planning to cut 4,500 jobs, which is 40% of its worldwide workforce, in an attempt to staunch huge losses.
The smartphone maker said it anticipated a loss of as much as £621m when it reports its second-quarter earnings next week.
Shares in the firm closed down 17% after briefly being halted following the announcement.
In August, the Canadian company said it was evaluating a possible sale.
In a statement on Friday, Blackberry's chief executive Thorsten Heins said: "We are implementing the difficult, but necessary operational changes announced today to address our position in a maturing and more competitive industry, and to drive the company toward profitability."
"Going forward, we plan to refocus our offering on our end-to-end solution of hardware, software and services for enterprises and the productive, professional end user."
iOS 7 Tweeters complain of problems
Analysis of more than five million tweets, blogs and forums posts from across the world suggests the issues affected more people than first thought.
When iOS 7 went live on Wednesday Apple customers soon took to Twitter to voice their frustration at how long the process was taking, with some sharing screen shots showing the update would take more than 24 hours to load.
The system had been heralded as a major step forward for Apple with chief executive Tim Cook calling it "the biggest change to iOS since the iPhone".
iOS 7 will come preloaded on the iPhone 5s and iPhone 5c smartphones, launched today, and was available for people with old Apple devices to download earlier this week.
