iPhone Security Flaw: Using a PIN Won't Help You


pcworld.com
Using a four-digit PIN to lock your iPhone doesn't really protect your data, security and IT blogger Bernd Marienfeldt has discovered. In an article describing the iPhone's business security framework, Marienfeldt has found a "data protection vulnerability" in Apple's iPhone 3GS.

Marienfeldt, working with security expert Jim Herbeck, has been able to reproduce the vulnerability on at least three non jail-broken iPhone 3GS handsets with different iPhone OS versions installed (including the latest). All tested iPhones were protected with a four-digit PIN.

In Marienfeldt's own words:

"The unprotected iPhone 3GS mounting is “limited” to the DCIM folder under Ubuntu <>please do make sure that the native Ubuntu system is fully up to date, e.g. “apt-get update, “apt-get upgrade” - any virtualization based solution will not work as described). I used the Alternate CD with x86 and AMD64 on different hardware."
