We often keep important data or personal information on devices that we feel is secure. Well think again. Even though these phones that Will O’Brien picked up had their personal messages locked by PIN simple plugging in a serial cable allowed the messages to be pulled right out.
“Hooking up the serial port is just a matter of connecting a 3/32″ audio connector up to a TTL USB serial cable. I was pretty amused by the two hundred SMS messages that were left inside the phones memory. I used a fake – phone number in these samples. Here’s an interesting bit: the phone actually had a pin on the messaging screen! Even without the pin I was able to pull the text messages off the phone.”
