![]() What this mean? Lets se on the next diagram what I made for you: In this case, the anti brute-force cracking mechanism is the time shifting technique. If the device have no anti brute-force attack mechanism then it is possible to easy crack the code. This type of security is to avoid of so called “brute-force attack” unlocking.īrute force attacking is a hacking technique to crack the code by systematically change and trying the code like this: 0000, 0001, 0002… the code is 1111. The radio has a security mechanism in the firmware, which will count more and more time to let enter the code again. It is on the screen because the unprofessional, mechanical technicians tried several times to unlock the radio without the good code. What he was done? Tried a fever attempt to unlock the radio but see what happened after entering a fever time the wrong code:ĭo you know why this “WAIT” is on the screen?
