The FBI could have saved money with this iPhone 5c hack

The FBI may have paid a small fortune to unlock an iPhone 5c used by the San Bernardino shooter. But a security researcher has demonstrated a way to do it for less than US $100. Sergei Skorobogatov at the University of Cambridge used a technique known as NAND mirroring to bypass the passcode retry limit on an iPhone 5c. Using store-bought equipment, he created copies of the phone’s flash memory to generate more tries to guess the passcode.   Skorobogatov detailed the whole process in a new paper that disputes the FBI’s assertion that the San Bernardino shooter’s iPhone couldn’t be accessed with the NAND mirroring technique.  To read this article in full or to leave a comment, please click here

Worth Reading: IPv6 versus v4 performance map

This is a world map showing the average value of the relative performance of observed connections in IPv6 compared to IPv4. The values are in units of milliseconds. For each observed dual stack end device, the TCP SYN exchange connection times are recorded and the best IPv6 and IPv4 Round Trip Times (RTT) are retained. …. Where IPv6 is faster, the IPv6 RTT is smaller than the IPv4 RTT and the result of the subtraction is a negative number, displayed as a shade of green in the above map. Where IPv4 is faster the result of the subtraction is a positive number, displayed as a shade of red in the map. —APNIC

Nenshou Fire: Recoil

My daughter has started a new fiction series on her blog; I’ll just link to it here for anyone who’s interested.

A cold circular object is pressed to my head, a hand reaching around to cover my mouth before I can make a sound. My eyes squeeze shut reflexively. Is this it? Is this how I’m going to die? After so much time of hiding, running, escaping the war around me, am I finally reaching the end of my life? My heart explodes inside me, waiting for the explosion of powder, marking the final moments of my life…but nothing comes. I open my eyes, surprised. What is this? Why hasn’t he made that one little motion that would end my life? —Nenshou Fire
