Hacker Reveals Mobile SD Card Flaws

Hacker Bunnie Huang has exposed security issues inherent with SD cards, the removable flash memory devices that store mobile phone information, a blog post authored by Huang indicated on January 2.

“The illusion of a contiguous, reliable storage media is crafted through sophisticated error correction and bad block management functions,” Huang in a blog post addressing the topic. “This is the result of a constant arms race between the engineers and mother nature; with every fabrication process shrink, memory becomes cheaper but more unreliable.”

Huang indicated that SD card manufacturers are leaving firmware unsecured, meaning that information may never be completely removable from these devices.
