Apple states that it uses data encryption to protect email message attachments, but a report from security researcher Andreas Kurtz, via ZDNet, claims iOS 7.0.4 and later does not include this security feature.
Kurtz reported this issue to Apple, which acknowledged the flaw, but provided no timetable for patching it. This isn't the first security issue Apple has faced this year. The company recently patched a serious SSL connection verification flaw in both iOS and OS X that allowed an attacker with a "privileged network position" to capture data protected by SSL/TLS.I verified this issue by restoring an iPhone 4 (GSM) device to the most recent iOS versions (7.1 and 7.1.1) and setting up an IMAP email account1, which provided me with some test emails and attachments. Afterwards, I shut down the device and accessed the file system using well-known techniques (DFU mode, custom ramdisk, SSH over usbmux). Finally, I mounted the iOS data partition and navigated to the actual email folder. Within this folder, I found all attachments accessible without any encryption/restriction
Update 3:11 PM PT: In a statement given to iMore, an Apple spokesperson said the company is working on a fix for the issue.
"We're aware of the issue," an Apple spokeswoman told iMore, "and are working on a fix which we will deliver in a future software update."
