iOS 8, that is... Apparently, Apple Inc.'s (NasdaqGS: AAPL) soon-to-be-released iOS 8, shows' evidence of significant attack surface minimization (e.g., File Relay, also known as com.apple.mobile.file_relay - the service that permits data egress via WiFi is now protected from, at least, easy attacks) . Jonathan Zdziarski's white paper informs us of the necessity to curtail iOS paths of data exfiltration, and such. Today's Must Read.

"File Relay (com.apple.mobile.file_relay) was the service responsible to causing the biggest potential privacy threat, by dumping large amounts of personal data from the device and bypassing the user’s backup encryption password. The file relay service is now guarded. While the service still exists, all attempts to extract data from it will fail with a permission denied error" -via the Jonathan Zdziarski Blog
