No Backdoor in iOS: Apple

With the release of iOS 8 Beta 4 for developers, several security hackers are already exploring the security issues of this latest operating system version from Apple. It is interesting to note that one particular hacker has already discovered vulnerabilities in the iOS, which point to a possible backdoor.

According to 9 to 5 Mac, security hacker Jonathan Zdziarski has reportedly discovered a backdoor access point to the iOS, which is actually supposed to be locked off and encrypted.

Apple, has, however, denied of any suggestions regarding the backdoor supposedly found by Zdziarski.

The report quotes a Tweet from Apple's Tim Bradshaw, which reads, "We have designed iOS so that its diagnostic dunctions do no compromise user privacy and security, but still provides needed information to enterprise IT departments, developers and Apple for troubleshooting technical issues. A user must have unlocked their device and agreed to trust another computer before that computer is able to access this limited diagnostic data. The user must agree to share this information, and data is never transferred without their consent."

"Apple has never worked with any government agency from any country to create a backdoor in any of our products or services," Apple continued in the statement.
