It is reported that several brands of smart locks have been cracked by a simple plastic "small black box". As long as the small black box is placed near the smart lock, the door can be opened. After the report came out, there was an uproar. The so-called safest smart lock is vulnerable?
There is only one truth!
Uncover the "little black box" incident with Xiao Ke ~
1, Question: Where did the mysterious little black box come from?
According to the report, the black box is smaller than the mobile phone, but twice as thick as the mobile phone. There are two buttons on the black box, one is the power button at the bottom and the other is the trigger switch. I saw the little black box close to the smart lock, and then pressed the trigger switch, and the smart lock was opened.
According to a professional, the principle of this small black box is actually to use the transformer to boost the voltage to form the capacitive element of the strong magnetic pulse interference lock, thus successfully cracking the automatic lock. Another electrical automation professional said that this is because the Tesla coil interfered with the motor drive board in the lock by electromagnetic, which made the electromagnetic induction bypass the detection of the smart lock and directly acted on the motor drive part to open the lock.
2. Experts confirmed that the smart lock with small black box second opening is of poor quality.
Afterwards, authoritative experts analyzed the smart lock successfully unlocked by the black box and found that the loopholes that the black box could break were caused by unqualified circuit boards and cables. Any electronic engineer with an electrician major or above in a regular secondary school can solve this problem. The masses need not panic excessively. As long as they buy a formal and guaranteed smart lock brand that meets the national electronic lock standards, there is no security risk of being unlocked by the black box.
3. Professionals in the industry: The security of smart locks is still stronger than traditional door locks.
At present, most smart locks on the market are unlocked by means of fingerprints, identification and credit cards. , convenient and fast. Some big brands will be supplemented by other security measures. For example, Colleni AI Smart Lock, which is independently developed without opening the first protection system, is connected to the intelligent management user APP, and will immediately send out an alarm notice in case of abnormal situation, so as to prevent problems before they happen.
