Jonathan Zdziarski finds evidence of backdoors in Apple iOS
A number of undocumented features in iOS have been found to essentially create backdoors for siphoning large amounts of users' personal data from Apple devices.
Jonathan Zdziarski, a researcher who often trains federal and state law enforcement agencies in forensic techniques, revealed the existence of the mostly hidden features. The data-stealing avenues have evolved over the last few years and may have been used by the U.S. National Security Agency to collect data on potential targets, Zdziarski said.
In 2013, German magazine Der Spiegel reported that the NSA had developed a "software implant" for the iPhone called DROPOUTJEEP. The app could be used to pull or push information and collect text messages, contacts lists, voicemail and geolocation data. The revelations were based on documents provided by ex-NSA contractor Edward Snowden.
