Smart 3D printing robot 30 seconds to crack the password lock

　　Samy Kamar independent software developers are keen to explore the vulnerability of the system. In 2005, he wrote a worm using Myspace vulnerability. Within 24 hours, he had adds 1 million friends. He designed a drone capable of wireless control other drones. He has also written a hardly removes the browser Cookie. Now, Kamar turned to a master combination lock. The robot through a 3D print, he may, within 30 seconds to open a master combination lock. Data what is the Foundation for the development of

　　Samy Kamkar unlocked hardware and software of the robot was published on the website. Known as the "combination of code-crackers" (Combo Breaker) robot can be done using 3D printing. Its central part is based on Arduino boards and Samy Kamkar software. It leverages Kamkar recently discovered a security vulnerability. In cases where no human intervention, it open a master combination lock for more than 5 minutes at a time.

　　In fact, Combo Breaker is not just using brute force. Kamkar has discovered a flaw in the password lock. Exploit the flaws, anyone can find low-end master lock combination, up to 8 attempts. Once you have the Combo Breaker, this process is fully automated. If the user is willing to learn, you can help the robot to find the first digit of the password. In this case, robot can open a combination lock in 30 seconds. "Do not do any work, it opens the locks need to try 80 combinations," Kamar on the Wired Web site says, "If you do a little test, it just need to try 8 combinations can be. "

　　Kamar say Combo Breaker does not cost more than $ 100. Meanwhile, he also pointed out that this will cause any major security problems. Master Lock 1 to 10 of the security level. His test is 3-level password lock. "A very simple principle," he said, "If you want to protect valuable items in the lockers, perhaps it should be using better locks. "

　　As to why open Combo Breaker of hardware and software, he said, this is in order to encourage hackers to try and share the "James Bond" type equipment's favorite. Meanwhile, he hopes that public awareness, the lower end of the lock is extremely unsafe. "Your security staff to understand this, but the general public does not know," he said, "I tried to make some public interest in things. I also hope that when people buy when the code lock, be able to make better choices. "
