Ex-iPhone jailbreaker Jonathan Zdziarski gave a presentation at HOPE/X conference regarding iOS security. He stated the platform is secure from malicious attacks, but backdoors are present for surveillance inside.
He presented ‘Identifying Backdoors, Attack Points, and Surveillance Mechanisms in iOS Devices,’ revealing several high-value undocumented forensic services running on the iPhone, and design omissions that appear or snooping.
A little more about Zdziarski: he was a well-known figure among the jailbreak community, and worked as a dev-team member under the name NerveGas. Since then, he has released 5 books, including Securing and Hacking iOS applications:
While the accusations do sound wild, they are in line with reports from last year that accuse iOS devices of having backdoors for surveillance. A leaked document also revealed DROPOUTJEEP, an iPhone-specific NSA-based program.
But Apple has denied it is involved in any kind of secret government projects on many occasions, and has also joined coalition of tech giants demanding transparency from the government. Apple issued the following statement after this report:
We have designed iOS so that its diagnostic functions do not 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. As we have said before, Apple has never worked with any government agency from any country to create a backdoor in any of our products or services.
